When we quote an Australian garrison fence project, we do not start with a product name, a catalogue photo or a price per metre. We start with the controlling project documents, panel and post geometry, picket and rail construction, weld requirements, coating route, site interfaces, approval hold points and evidence required before shipment.
That distinction matters because “Garrison”, “Diplomat”, “Hercules” and “steel picket fence” can describe similar-looking systems without proving that their sections, connections or finishes are equivalent. The Queensland school-security example in this guide shows how detailed an owner specification can be, but it is not a universal Australian standard. The latest tender documents, drawings, addenda and local design responsibilities always control.
In this guide, we show how we turn those documents into a factory-quotable schedule, help buyers compare suppliers on the same basis and prepare a clearer request for steel spear top fence panels.
Short answer: A quotable garrison fence schedule needs the document revision, panel and post sizes, picket spacing basis, rail construction, spear method, weld details, coating system, fittings, quantities, drawings, evidence and delivery terms. “To Australian Standard” is not a substitute for those fields.
What Australian Buyers Mean by “Garrison Fence”
In Australian commercial fencing, garrison fencing usually refers to an open steel security panel made with vertical pickets, horizontal rails and square posts. A pressed or crimped spear profile commonly creates the pointed top. However, market terminology is not a controlled specification.
Commercial sources may use Garrison, Diplomat, Hercules, pressed spear fencing and tubular steel picket fencing for overlapping product families. That does not mean every panel is interchangeable. When we review an enquiry, we confirm the following before treating two offers as equivalent:
- picket or pale profile, section and wall thickness;
- whether the spear is pressed from the same tube or attached separately;
- panel height and width;
- picket centres and clear opening;
- rail section, rail position and connection method;
- post type, section and length;
- brackets, shrouds, caps and anti-tamper fixings;
- steel grade and material route;
- galvanising, pre-treatment and powder-coating system;
- required drawings, samples and inspection evidence.
If you are still comparing top styles and general security applications, read our guide to spear top perimeter security. This article has a narrower job: showing how we convert Australian project clauses into manufacturing and RFQ inputs.
Garrison is not the same as palisade or chain-mesh fencing
A tubular garrison panel uses tube or picket sections connected to rails. Palisade fencing generally uses formed pales with a different profile and connection system. Chain-mesh fencing uses woven wire fabric and a separate framework. All can serve perimeter-security tasks, but their drawings, tests, components and installation interfaces differ.
The practical rule is simple: identify the construction from the drawing, not from the sales name.
Steel and aluminium are not automatic substitutes
This guide focuses on steel. An aluminium panel may look similar, but material, section strength, connection details, coating and owner acceptance can be different. If a tender specifies steel, an aluminium alternative should only be offered through the project’s formal equivalent-product or deviation process.
For other steel configurations, use our steel fence panel range as the category page. We do not force a blade, flat-top or rod panel into a garrison specification merely because the appearance is close.
Start With the Project Specification, Not a “Standard Panel”
The phrase “standard garrison panel” is useful in a catalogue, but it is too vague for us to prepare a defensible tender quotation. One supplier may quote thinner pickets and rails, another may exclude posts or evidence, and a third may use a different coating route. The lowest price may therefore represent a different scope.
When we receive a project enquiry, we start the RFQ review with document control:
- project owner or issuer;
- specification title and document number;
- revision and issue date;
- relevant clause numbers;
- drawing numbers and revisions;
- BOQ or panel schedule;
- tender addenda and clarifications;
- approved-equivalent procedure;
- required submittals and approval dates.
If two documents conflict, do not guess which one wins. Put the conflict in the clarification schedule and ask the project team to confirm the document hierarchy.
Separate the overseas product scope from local project design
From our factory side, we can normally confirm the offered material, sections, manufacturing method, dimensional tolerances, finish route, available evidence, packing and commercial assumptions. Australian project parties normally control the site survey, underground services, wind and soil inputs, footing design, permits, installation method, local WHS requirements, engineering sign-off and final acceptance—unless the contract explicitly assigns those tasks to appropriately qualified parties.
That boundary should appear in the quotation. It protects both sides from an offer that seems complete but silently excludes a critical design or approval task.
Use a clause-by-clause response
In our quotation review, we assign one of four responses to each requirement:
- Comply: the offered product and evidence match the stated clause, subject to final approved documents.
- Deviation: the supplier proposes a stated difference and provides the technical/commercial effect.
- Clarification required: the clause is incomplete, conflicts with another document or needs an owner decision.
- Not in supply scope: the responsibility belongs to the installer, engineer, principal or another contractor.
A general statement such as “complies with Australian standards” cannot replace this matrix. Compliance is only meaningful when the item, edition, test method, sample, acceptance criterion and responsible reviewer are clear.
Queensland School Security Fencing: A Worked Example, Not a National Template
We use the current Queensland Department of Education Specification for school security fencing as a useful worked example because it turns a product name into measurable construction and evidence requirements. It also says quotations must follow the department’s tender process and include site-specific and handover information.
The values below illustrate how one owner writes a security-fence specification. They are not default TOPSFENCE dimensions and not an Australia-wide specification. Recheck the current PDF and the actual project documents before using them in an RFQ.
| Field | Queensland Department example | What to write in the RFQ |
|---|---|---|
| Minimum fence height | 2100 mm above ground | Required height, reference level and tolerance |
| Standard panel width | 2400–2500 mm | Panel width, post centres and custom-panel rules |
| Maximum ground clearance | 150 mm | Clearance, measuring point and slope/infill treatment |
| Rails | 2 rails, 40 × 40 × 2 mm | Section, wall thickness, centres and top-rail position |
| Pickets | 25 × 25 × 1.6 mm, 2100 mm long | Section, wall thickness, length and steel route |
| Picket spacing | 115 mm centres | State centres and calculated clear opening |
| Spear top | Cut and pressed/crimped from the same tube | Profile drawing; confirm no separately attached finial if prohibited |
| Straight-line post | 75 × 75 × 3 mm, 3000 mm long | Post type, section, length, cap and connection |
| Corner post | 100 × 100 × 4 mm, 3000 mm long | Identify corner/termination types separately |
| Picket-to-rail welds | Four per picket, alternate sides; silicon bronze wire | Weld locations, count, consumable and finish requirements |
| Coating | Selected by corrosion category | Substrate route, pre-treatment, primer/topcoat and evidence |
The same document differentiates corrosion environments, surface preparation, coating routes, powder application and testing. It also addresses post footings, slopes, underground services, drainage, trees and onsite welding. Those site matters should not be copied into a generic overseas panel price without confirming who owns the design and installation responsibility.
Why procurement evidence matters as much as geometry
The City of Wanneroo’s 2025 recommendation report for Tender 24008 shows that a real garrison-fencing procurement can assess more than price. Its published qualitative criteria included sustainable procurement, WHS, resources and capacity, similar experience, and methodology. The report used a schedule-of-rates contract and did not publish the confidential commercial detail.
For an importer or contractor, the lesson is not to copy that council’s criteria. It is to recognise that panel dimensions alone do not make a conforming project submission. The supply package may need evidence that supports the bidder’s wider method, capacity, traceability and quality plan.
Translate Tender Clauses Into a Manufacturer RFQ Schedule
The fastest way for us to reduce factory assumptions is to convert the tender into a structured schedule. We give every row its source clause and approval owner.
Panel and picket fields
We ask the buyer to state:
- overall panel height and width;
- reference level and ground clearance;
- standard, end, corner, stepped, raked and infill panel quantities;
- picket section and wall thickness;
- picket centres and clear gap;
- pressed/crimped, welded or other top profile;
- dimensional and squareness tolerances;
- visible face and security side.
“Picket spacing 115 mm” is ambiguous unless the RFQ says whether that is centre-to-centre or a clear gap. The drawing should show both.
Rail, post and connection fields
We ask the buyer to state the rail section, wall thickness, number, centres and distance from the picket top. We separate line, end, corner, return and gate-interface posts, then identify each post section, length, cap, bracket or shroud, fixing position and anti-tamper requirement.
Panel width and post centres are not automatically identical. Brackets, clearances and site layout can change the relationship, so both belong on the approved drawing.
Material and coating fields
We ask for the required steel grade, referenced material standard, substrate coating route, fabrication sequence, surface preparation, primer, powder topcoat, colour/gloss, thickness criteria, repair method and required evidence. If the project team has not selected a corrosion category or coating system, we mark that input as not confirmed instead of making an invisible factory assumption.
Drawings, samples and approval hold points
Specify:
- shop-drawing format and required sections;
- language, units and revision system;
- sample or first-article inspection (FAI);
- inspection and test plan (ITP);
- evidence required before material purchase, mass production and shipment;
- who can approve a deviation;
- what happens if the sample and drawing conflict;
- change-control procedure after approval.
Commercial and export fields
A technical schedule is still incomplete without quantities and delivery scope. List quantities by panel and post type, spare parts, hardware kits, packing marks, destination port, Incoterm, container/handling limits, documentation, target approval date and required delivery date.
| Tender clause or input | RFQ field | Supplier response/evidence | Approval owner |
|---|---|---|---|
| Panel geometry | Height, width, tolerance, clearance | Marked-up shop drawing + first-article measurement | Project designer / buyer |
| Picket spacing | Centres and clear gap | Drawing calculation + gauge/measurement photo | Buyer / inspector |
| Pressed spear | Same-tube or attached component | Section detail + sample close-up | Project designer |
| Punched rail | Opening and picket path | Section drawing + sample/fixture photo | Buyer / technical reviewer |
| Welding | Location, count, consumable, finish | Welding instruction/record as required + close-up | Technical reviewer |
| Coating | Route, pre-treatment, thickness, colour | Material/coating documents + inspection record | Coating reviewer / buyer |
| Posts and brackets | Type, section, length, fixing | Component schedule + drawings | Engineer / installer / buyer |
| Export packing | Bundle, protection, marks, unloading limits | Packing drawing + packing/loading photos | Importer / warehouse |
Punched-Through Rails vs Face-Welded Pickets
Two black spear-top panels can look similar from a distance while using different picket-to-rail construction.
In a punched-through design, the picket passes through an opening in the rail. The RFQ should define the opening, alignment, weld locations and treatment of cut or heat-affected areas. In a face-welded design, the picket terminates at or attaches to the rail face. The fabrication method, load path, weld access and finish treatment differ.
If the owner specification requires punched-through rails, we will not present a face-welded panel as “equivalent” without the formal deviation and approval process.
Define the weld instead of writing “fully welded”
“Fully welded” does not tell our production team:
- which faces receive welds;
- how many welds apply to each picket and rail;
- weld size or visual acceptance criteria;
- required consumable or process;
- whether a welding instruction, procedure or personnel qualification is required;
- how zinc-coated surfaces and finished welds are treated;
- whether onsite welding is allowed.
The Queensland example specifies alternate-side weld locations and silicon bronze wire. That is an owner requirement, not proof that the same method suits every project or that a supplier can provide it without confirmation. Ask for a marked-up drawing and a sample close-up before mass production.
Evidence for sample and mass production
Subject to the confirmed project scope and our capability review, we can plan a practical approval pack that may include:
- first-article height, width, diagonal/squareness and spacing report;
- front, back and section close-ups of the rail/picket interface;
- spear profile photo against the approved drawing;
- weld-location photo index;
- material batch or certificate reference;
- coating-process and finished-thickness records required by the project;
- nonconformance and deviation log;
- signed sample approval before mass production.
Do not publish or accept a certificate without checking which product, batch, method and acceptance criterion it covers.
Galvanising and Powder Coating: Specify the Route and the Proof
“Galvanised and powder-coated” still leaves major questions unanswered. The RFQ needs to state the substrate, when the metallic coating is applied, how cutting and welding are handled, what pre-treatment precedes powder coating, and what evidence is required.
AS 1397, AS 4792 and AS/NZS 4680 are not interchangeable labels
The Queensland school document references several standards for different materials and processes. In simplified terms:
- AS 1397 relates to continuously hot-dip metallic-coated steel sheet and strip;
- AS 4792 relates to hot-dip zinc coatings on ferrous hollow sections applied by continuous or specialised processes;
- AS/NZS 4680:2025 is the current Standards Australia catalogue entry for hot-dip galvanised coatings on fabricated iron and steel articles and supersedes the 2006 edition.
Those descriptions do not authorise a supplier to choose a standard by marketing preference. The specified material form, fabrication timing and owner documents decide which reference is relevant. Review the current AS/NZS 4680:2025 catalogue entry and obtain the controlled standard through authorised channels when needed.
Corrosion category drives the system
The Queensland example uses the installation’s atmospheric corrosion category to determine coating requirements. It gives different routes for C3 and C4 conditions. That is useful procurement logic: start with the owner’s confirmed environment and then select the substrate, pre-treatment, primer, topcoat and evidence package.
Do not describe all of Australia as one corrosivity zone. Coastal exposure, industrial contaminants, shelter, wetness, maintenance and local microclimate can change the decision. The appointed project professional should confirm the category and acceptance criteria.
Ask for evidence with a defined scope
Possible evidence includes a material certificate, coating supplier technical data, pre-treatment record, batch reference, thickness measurements, cure or adhesion results, required test report, approved repair method and finished-product photos. The project must decide which items are mandatory and whether manufacturer records, third-party reports or an accredited laboratory are required.
NATA explains that ISO/IEC 17025 accreditation supports competent testing and calibration. However, a NATA name or logo does not prove that every test is accredited. Use NATA’s accredited-organisation search to confirm the organisation, location, test or standard and accredited scope. Then check that the report identifies the relevant sample and batch.
Our coating, inspection and export packing process shows the normal order path from confirmed specifications through cutting, welding, coating, final checks, packing and loading. We still agree project-specific evidence before production.
Drawings, Slopes, Returns and Installation Interfaces
We use the shop drawing to turn the buyer’s words into a manufacturable panel schedule. At minimum, we show:
- project and drawing identifiers, revision and date;
- panel marks and quantities;
- height, width and post centres;
- picket/rail/post sections and wall thicknesses;
- picket centres and clear opening;
- rail centres and top-rail position;
- spear profile and manufacturing method;
- weld and bracket details;
- ground clearance;
- finish code and visible face;
- interfaces with returns, adjacent fences and openings.
Stepped and raked panels belong in the schedule
Do not send only the total fence length for a sloping site. Identify the gradient, change in level, step height, shortest panel, raked-panel geometry and any infill or drainage interface. A site survey and approved layout are required; there is no safe universal slope limit for every panel and foundation.
Keep gate scope to the interface
This article does not attempt to specify a complete gate or access-control system. The panel schedule should still identify the gate-interface post, return, adjacent full panel, clear opening and who approves the local gate design. Wide vehicle gates, foundations, hardware and operators require separate project-specific engineering and procurement.
Factory Evidence Buyers Should Request Before the PO
Evidence is most useful when it is planned before the price and lead time are fixed.
Before quotation
Ask us for a capability response against the schedule, representative construction photos, available material and finish routes, proposed deviations, evidence availability and commercial assumptions. We mark an item “clarification required” when we cannot verify an input.
Before sample approval
Request the marked-up shop drawing, document samples, first-article inspection format, welding/coating evidence plan and packing concept. If the project needs a laboratory report, confirm the method, sample selection and accepted laboratory scope before making the sample.
Before mass production and shipment
Confirm the approved drawing, sample approval, ITP and hold points. Agree on batch traceability, inspection sampling, nonconformance handling, final report, bundle marks, packing list and loading-photo index.
The following claims require specific evidence and reviewer approval:
- “compliant with Australian standards”;
- a stated salt-spray duration or service life;
- “NATA tested” or “NATA certified product”;
- structural or engineering certification;
- government, school, airport or other project references;
- fixed warranty performance in an unconfirmed environment.
If the evidence is not available, remove the claim or write “available subject to project confirmation”.
Compare Garrison Fence Quotations on a Like-for-Like Basis
First normalise the product. Then normalise the commercial scope.
| Comparison group | Fields to align | Common hidden difference |
|---|---|---|
| Panel | Height, width, tolerance, picket count/spacing | Centres confused with clear gap |
| Pickets and rails | Sections, wall thickness, top profile, connection | Face-welded offered against punched-through requirement |
| Posts and fittings | Post types, sections, lengths, brackets, fixings | Gate/corner posts excluded or priced as line posts |
| Coating | Substrate route, preparation, primer/topcoat, colour, evidence | “Powder-coated” with no metallic-coating route |
| Approval evidence | Drawing, sample, FAI, reports, photo index | Documents priced later or unavailable |
| Packing | Separators, bundles, labels, hardware cartons | Finish protection and unloading limits omitted |
| Commercial | Quantity tolerance, spares, Incoterm, lead-time trigger | Freight or approval delay assigned differently |
Red flags include a one-line “standard garrison fence” offer, a price per metre without components, no document revision, no coating route, drawings that disagree with the quotation, an unexplained “certified” claim, or missing exclusions and deviations.

Frequently Asked Questions
Is garrison fencing an Australian Standard product?
No. “Garrison fencing” is a market product description, not one universal Australian Standard product. A project may reference several material, welding, coating, design or installation standards plus owner-specific dimensions. Assess each clause and item separately.
Are Garrison, Diplomat and Hercules fences the same?
The names may be used for similar tubular steel picket systems, but they are not reliable proof of equivalence. Compare the picket/pale profile, rail connection, spear method, posts, coating and approved drawing.
What is a typical garrison fence panel size?
Market sizes vary. The Queensland school example uses a minimum height of 2100 mm and standard panel widths of 2400–2500 mm, but those figures belong to that owner specification. Use the current project schedule for the offered panel.
Should picket spacing use centres or clear gaps?
State both. Centre-to-centre spacing and the clear opening are different measurements. The drawing should show the reference faces and tolerance so the factory and inspector use the same method.
What is the difference between punched rails and face-welded pickets?
A punched-through picket passes through an opening in the rail; a face-welded picket terminates at or attaches to the rail face. Their fabrication, weld access and finish treatment differ. Do not substitute one for the other without approval.
Is pre-galvanised steel the same as hot-dip galvanising after fabrication?
No. The metallic coating is applied at a different stage and the relevant material/process references differ. Cutting, punching and welding also create different treatment questions. Follow the project’s specified route.
Which Australian coating standard should I put in the RFQ?
Do not choose from the standard number alone. Start with the owner specification, material form, fabrication route, confirmed corrosion category and evidence requirements. Have the project’s qualified technical reviewer confirm the applicable edition and acceptance criteria.
What does a NATA-accredited report prove?
It supports the competence of the accredited organisation for activities within its listed scope. Check the organisation, location, method/standard, scope and report sample. A logo alone does not prove every test is accredited.
Can TOPSFENCE design post footings for an Australian site?
We can provide product geometry and agreed manufacturing information. Site wind, soil, footing, permits, installation and engineering sign-off remain with the appointed Australian project parties unless a contract explicitly assigns them to an appropriately qualified provider.
What should I send for an accurate quotation?
Send the latest specification, drawings, BOQ or panel schedule, project location/environment, quantities, finish/evidence requirements, destination port, preferred Incoterm and required dates. Mark unknown fields as not confirmed.
Can a supplier quote an approved equivalent?
Only through the tender’s equivalency and approval process. The supplier should identify each deviation, technical impact and supporting evidence. An alternative is not approved merely because it looks similar or is described as heavy duty.
How should panels be packed for import?
Agree the bundle size, finish protection, panel/post separation, hardware cartons, labels, forklift and container limits, unloading plan and photo records. Packing should match the importer’s warehouse and project-release sequence.
