A quote for a heavy duty temporary fence for construction sites usually arrives as one line: “2400 × 2100 mm panel.” That is width and height — 2.4 m across, 2.1 m high — and it is the shortest sentence on a page that should carry far more. The numbers say how the panel fits a run; they say nothing about the steel, coating or hardware that decide whether the fence survives a season.
DB Fencing builds the format around a 40 mm frame tube, hot-dip galvanises its temporary fencing line to above 42 microns, and supplies against AS 4687-2022 / AS 4687-2007 from Anping, Hebei Province — the Global Wire Mesh Town. Australia and New Zealand take 75% of those exports. This guide reads one line by line: what each figure means, which rows should never be blank, and what to demand before comparing prices.
Key Takeaways
- 2400 × 2100 mm is width × height: 2.4 m of coverage at 2.1 m high — roughly 42 panels per 100-metre run. Confirm the orientation on a drawing.
- “Heavy duty” is steel, not a label: this line’s construction-grade panel carries a 40 mm frame tube; the Econo lightweight grade in the same family uses a lighter 3 mm tube build.
- Coating is fixed on paper: the temporary fencing line is hot-dip galvanised above 42 microns. Ask for a batch coating report, not a brochure claim.
- Blank rows are the tell: wire diameter, mesh aperture and tube wall thickness belong on the sheet — request missing figures in writing before order confirmation.
- The panel is half the purchase: feet, clamps, bracing and ballast decide whether it stands, and AS 4687 wind obligations are site-specific.
- Commercial baseline: minimum order 100 panels, 20–25 days bulk, 7-day stock dispatch, FOB / CIF / CFR / DDU / DDP, flexible and negotiable payment terms.
What 2400 × 2100 mm Tells You — and What It Doesn’t
DB builds this format for its Australia and New Zealand market, which takes 75% of its exports. Do the arithmetic before the quote arrives: a 100-metre perimeter needs roughly 42 panels; 240 panels fence about 576 metres. Couplings, feet and bracing scale at the same ratio, so a width misread multiplies through the whole accessory list.
Two suppliers can both write “2400 × 2100” and mean different things — one lists width first, the other height. Imperial formats add a layer: some imperial quotes list height first — confirm on the drawing. Ask for a drawing with the quote and check which figure the supplier calls the height.
The Fields a Complete Spec Sheet Carries
A sheet earns the word “spec” when every row affecting price or performance carries a number. Run any quote through the table below. A blank row is what a later dispute is argued over: request the missing figure in writing before order confirmation.
| Spec field | What the sheet should state | Buyer check |
|---|---|---|
| Overall panel size | 2400 mm wide × 2100 mm high, orientation on a drawing | Confirm which figure is the height |
| Frame tube | 40 mm diameter on the heavy duty line | Ask for wall thickness if the row is blank |
| Mesh wire diameter | A stated millimetre figure for the infill wire | Check it against the class you ordered |
| Mesh aperture | Vertical × horizontal opening dimensions | Blank row? Request it in writing |
| Coating | Hot-dip galvanised after fabrication, above 42 microns on this line | Demand a batch coating report |
| Feet, clamps, bracing | Model and quantity per panel listed with the panels | One supplier, one compatibility risk |
Wall thickness is the row most often left vague and the one that quietly moves price. A tube that reads 40 mm on the outside can carry different steel depending on the wall, so two quotes identical on size can differ in weight per panel. Ask for the wall figure and panel weight together; a factory building to a written specification has both.
Heavy Duty Temporary Fence for Construction Sites vs Econo: Same Job, Different Steel
DB Fencing also offers an Econo lightweight grade in this product family: the construction-grade panel on a 40 mm frame tube, the Econo on a lighter 3 mm tube build. The Econo suits short-duration, low-load work — a weekend event line, light demarcation. It fails at what heavy duty exists for: repeated handling, impact from plant, and looking professional after a full season of weather.
The purchasing error is not buying the wrong panel; it is comparing two quotes that describe different panels. If the cheapest line item names neither the frame tube nor the wire class, the price gap is steel, not efficiency. For a live construction-site perimeter, specify the 40 mm-tube panel and treat Econo pricing as a different product family.
Coating: 42 Microns and the Figure from Another Line
Zinc thickness is the durability number, quoted in microns. DB Fencing hot-dip galvanises its temporary fencing line to above 42 microns after fabrication — the class held for outdoor and coastal exposure, which matters when panels live outdoors between hire jobs. The coating does the structural work; colour is a separate line item, and a smart finish over thin zinc still rusts.
Coating figures circulate across product families. The same factory’s galvanised livestock corral panels run to a different benchmark of 18–28 microns — right for that product, wrong for a site fence. Check any micron figure refers to the temporary fencing line, then the paperwork: DB Fencing is ISO9001 certified and SGS audited, and a batch coating report settles what a brochure claim cannot.
The Hardware Lines Below the Panel
A panel is a component; the fence is a system, and the sheet should carry the accessories with the same detail as the steel. On Australian sites the panel stands on flat steel feet or plastic feet — DB Fencing moulds its own plastic feet on an injection machine it is the only Anping supplier to run, and offers recyclable rubber feet as an alternative. Clamps join panels through their verticals, bracing props the line, and ballast blocks or reusable ballast load the feet where ground is hard or the site exposed. Each item raises a compatibility question — foot cavity to tube size, clamp to post — and our temporary fence foot compatibility chart works through the matching logic.
Wind is where the standard bites. AS 4687-2022 and AS 4687-2007 govern temporary fence structures in Australia, but the bracing and ballast a site needs depend on wind exposure, run length and ground conditions — variables only the site’s own assessment settles. Confirm the bracing schedule for your conditions rather than copying a catalogue default; one factory for panels and hardware keeps three suppliers’ tolerances from meeting on one pallet.
When 2400 Is Not the Right Panel
The same sheet family carries longer formats. The 3300 × 2100 mm Maxi panel covers 3.3 m per unit against 2.4 m — about 30 panels per 100-metre run instead of roughly 42, so fewer couplings and feet, at the cost of heavier handling and bigger stacks. The 6ft × 8ft and 6ft × 9.5ft formats stocked for the Perth market sit in the same conversation: imperial names, metric reality, and a height-first habit the drawing must resolve.
Mixed fleets create the quiet problem. A hire yard adding Maxi units to a 2400-panel fleet needs to know which feet, clamps and spares cross over, because the accessories rarely do. Before extending a fleet, read the panel section of our guide to temporary fencing panel sizes, tube gauges and tolerances, and ask any supplier which accessories each format shares.
The Commercial Block: MOQ, Lead Time, Incoterms
The last third of the sheet is commercial. The minimum order is 100 panels — about 240 metres of fenced run at this format. Bulk production runs 20–25 days from order confirmation; stock configurations dispatch in 7 days, and the 7-day stock program covers a sudden perimeter without waiting on a production slot. Behind the dates sits capacity: ten welding lines, output up to 2,000 sets per week, a factory established in 2009 with 14 years of export experience.
Quotes come on FOB, CIF, CFR, DDU or DDP terms, payment terms are flexible and negotiable to the order, and a written specification returns a quote within 24 hours. Read those lines like the steel rows: the lead time that matters sits next to your configuration, and the incoterm is the one your freight reality supports.
Frequently Asked Questions
What does 2400 × 2100 mm mean on a temporary fence panel?
The panel is 2400 mm wide and 2100 mm high — 2.4 m of coverage at 2.1 m of height. Suppliers do not all write the pair in the same order, so confirm on a drawing which figure is the height before counting panels.
What makes a temporary fence panel “heavy duty”?
The steel behind the outline: this factory’s construction-grade 2400 × 2100 mm panel carries a 40 mm frame tube, while the Econo lightweight grade in the same family uses a lighter 3 mm tube build.
What galvanising thickness should construction-site panels have?
Hot-dip galvanising above 42 microns, applied after fabrication — the class this factory holds on its temporary fencing line. Check that any micron figure refers to that line, and request a batch coating report with the order.
Do 2400 × 2100 mm panels comply with AS 4687?
DB Fencing supplies the format against AS 4687-2022 / AS 4687-2007, but the standard’s wind, bracing and ballast obligations depend on site exposure and run length — confirm the schedule with the site’s engineer.
What is the minimum order and lead time for these panels?
The minimum order is 100 panels. Bulk production runs 20–25 days from order confirmation, stock configurations dispatch in 7 days, and a quote on a written specification comes back within 24 hours on FOB, CIF, CFR, DDU or DDP terms.
Conclusion
A 2400 × 2100 mm panel is a standard outline carrying non-standard steel underneath. The sheet decides the argument: the tube and wire class behind “heavy duty,” the micron figure behind the galvanising, the wall-thickness row that price comparisons rest on, and the hardware that keeps the fence standing in wind. Read those rows and two identical-looking quotes stop being comparable — which is when you start buying well.
Send your panel count, format and the rows above as a written specification, and have the drawing, coating report and accessory schedule attached to the 24-hour quote.
