Polyester does not rust. Mine water, acid rain and coastal salt fog leave it unchanged — there is no galvanising to wear through and no weld points to break.
Burns only while a flame is applied and extinguishes once the source is removed, with no molten drip. Measured flame time ≤ 2.9 s; afterglow ≤ 2.2 s.
A conductive additive keeps surface resistance inside the safe band, so the net does not build up charge, does not attract dust, and cannot throw a spark.
UV stability comes from the polyester molecule itself rather than a surface coating that erodes — specified for a 20-year service life.
A single strand breaks at 2746 N. Across a one-metre width the knitted mesh carries 102 kN/m.
At 0.8 kg/m² it is a fraction of the weight of a welded steel mesh of comparable pitch — one person can carry and place a roll.

High-tenacity polyester yarns are warp-knitted into a continuous mesh. The knitted structure is what carries load across the roll — there is no border rope and no woven edge to fail.

The mesh is coated with a flame-retardant and anti-static polymer. These two additives exist because underground regulations require them — a net that burns, or that accumulates static charge, cannot go underground at all.

Every production lot is sampled and tested for strand diameter, break load, elongation, flame time and surface resistance before release. Results are recorded per batch, not per catalogue.

Break load on the current grade has been verified by an accredited national labour-protection testing centre (report 2025-004). That report, the batch record and the certificate of origin travel with the goods.
Blowtorch, fifteen seconds
Hold a torch against the panel, then take it away. The net should stop burning on its own and must not drip molten material.
Utility knife and shears
Work a knife across a single strand, then try heavy shears. Note how much force it takes to part one thread.
Known weight, measure deflection
Hang a known weight — a bucket of water works — from a strand. Measure how far it stretches, and whether it springs back.
A sample kit contains a 0.2 m² panel cut from production stock and is credited back in full against your first roll order.
