HJ FenceAS 4687 Temporary Fencing: The Importer's Compliance Guide
If you sell, hire or install temporary fencing in Australia or New Zealand, AS 4687 is the number that decides whether your product is accepted on site. Head contractors write it into purchase orders, councils write it into event permits, and inspectors reach for it when something goes wrong. Yet a large share of imported "AS 4687 compliant" fencing has never been near the standard. This guide explains what AS 4687 actually requires, where imports typically fall short, and how to buy compliant fencing with confidence.
What is AS 4687?
AS 4687:2007, Temporary fencing and hoardings, is the Australian Standard covering the design, stability and strength of temporary fencing systems — the portable panel-and-foot fencing used around construction sites, roadworks, events and demolition zones. It exists for one reason: temporary fences fall over surprisingly easily, and a falling 2.1 m steel panel injures workers, children and passers-by.
The three things the standard actually checks
- Strength — panels, frames and clamps must withstand defined loads without permanent deformation. Welds and tube wall thickness are what deliver this.
- Stability — the installed fence must resist overturning from wind and incidental impact. This is where most non-compliant systems fail.
- Footing and ballast — feet must provide adequate ballast mass and footprint; bracing (stays) is required where the base configuration is insufficient.
Wind loading: the number one failure point
A 2100 × 2400 mm fence panel is effectively a sail. Add shade cloth or printed banner mesh — which site managers love for dust control and advertising — and wind load multiplies several times over. AS 4687 requires the fence system to be assessed for the wind conditions of its region, and in practice that means:
- Sheltered urban sites — standard feet at every panel may suffice
- Exposed, elevated or coastal sites — heavier ballast and bracing stays become necessary
- Any fence with shade cloth or banners — treat as exposed regardless of location, add stays and extra ballast
Hardware is where compliance is won or lost
Panels themselves rarely fail an inspection — hardware does. Undersized clamps that slip, thin-wall frame tube that kinks, and stays sold as optional extras when the design needs them. A compliant system is panels plus feet plus clamps plus stays, engineered together. Buying panels from one supplier and hardware from another is how non-compliant fences get built from compliant parts.
What to demand from an "AS 4687 compliant" supplier
- Panel dimensions and frame specification in writing (2100 × 2400 mm, 32 mm OD tube, stated wall thickness)
- The stability assessment or test data behind the compliance claim
- Foot ballast mass stated per foot (not per pair)
- Stays and clamps included in the system offer, with quantities
- Interchangeability with Australian hire-fleet dimensions
Galvanizing: pre-galv versus hot-dip after welding
Budget panels are welded from pre-galvanized tube and wire, leaving every weld as a bare steel rust point — visibly bleeding rust within months in Australian sun and coastal air. Hot-dip galvanizing after welding coats welds, cut ends and all, and is what the Australian market expects of quality fencing. HJ's standard is a minimum 300 g/m² zinc coating, verified by SGS testing, with temporary fence panels built specifically to AS 4687 geometry and ballast requirements.
Importer's AS 4687 checklist
- Get the full system specification — panel, frame, clamp, foot, stay — in writing
- Confirm foot ballast mass and the wind configuration it supports
- Ask for the stability assessment or test documentation
- Specify hot-dip galvanized after welding, minimum 300 g/m²
- Verify frame tube wall thickness (and weigh a sample foot on arrival)
- Check panel dimensions interlock with your existing fleet
- Order stays with the panels, not after the first storm
- Keep the paperwork — inspectors ask for it
Frequently asked questions
Is AS 4687 compliance legally mandatory in Australia?
The standard itself is voluntary, but Work Health and Safety regulations require site perimeters to be safe — and AS 4687 is the accepted benchmark courts and inspectors use to judge that. Most head contractors, councils and event permit authorities simply write "temporary fencing to AS 4687" into their requirements, making it mandatory in practice.
Does AS 4687 apply in New Zealand?
New Zealand has no direct equivalent standard, so AS 4687 is widely referenced there as best practice for temporary fencing on construction sites and events. Fencing built to AS 4687 is accepted across the Tasman without modification.
What wind rating does temporary fencing need?
AS 4687 requires the installed fence to resist overturning under wind loads appropriate to the region. In practice that means standard feet are adequate for sheltered sites, while exposed or coastal sites and any fence carrying shade cloth or banner mesh need bracing stays and/or heavier ballast. Your supplier should state the wind category their configuration was assessed against.
What is the standard temporary fence panel size in Australia?
2100 mm high × 2400 mm wide is the dominant size, with 32 mm OD frame tube. Concrete-filled blow-molded feet and two clamps per panel joint complete the standard set. HJ's standard panel matches these dimensions exactly, so imported panels interlock with existing Australian hire fleets.
How heavy should temporary fence feet be?
Common concrete-filled plastic feet run 18 kg, 25 kg and 32 kg. Around 25 kg per foot is the typical baseline for AS 4687 stability on standard 2100 mm panels in moderate wind areas; exposed sites step up to 32 kg feet plus stays. Featherweight feet under 15 kg are a red flag.
Who can certify that fencing meets AS 4687?
Manufacturers self-assess against the standard, backed by engineering calculations or physical testing of stability and strength. Ask your supplier for their assessment documentation and test data — reputable factories provide it without hesitation. Independent labs such as SGS can also verify materials and coating mass.
