Range · Composite fall protection grids
The composite fall protection grid, for open structures.
A fall protection grid has one job: to stop a fall on the day the hatch or chamber is open. The idréva bars, in GRP (glass-reinforced plastic) composite, have been validated by a 1,200 J impact test, for T1 hatches and civil works installation alike.

02 — Applications
When the structure opens onto a drop.
As soon as a hatch or chamber is opened for work, the structure becomes a drop of several metres. Collective protection comes before personal protective equipment.

Hatches
Access hatches
Wastewater treatment plant, valve chamber, reservoir: the grid stays in place under the T1 hatch and drops back down after each entry.

Non-standard structures: the module can be cut to size on site and combined with others to cover the full width of the opening.
Civil works grids03 — Why composite
The grid closes by itself.
Impact“Validated at 1,200 J.”
3 consecutive impacts following the INRS ED 6076 method: the bag does not pass through. Validated by a third-party inspection body.

Corrosion“Unaffected by H₂S and salt.”

Operation“Just one operator.”
The grid drops back into the closed position by itself: nobody has to close it.

07 — Common questions
What people ask us before choosing a grid for fall protection.
Seven short answers. For anything else, your account manager replies in the pro portal.
With a 1,200 J impact test, following the INRS ED 6076 method, Annex 5: a 50 kg bag dropped from 2.40 m onto the grid resting on its frame. The bars were validated by a third-party inspection body after 3 consecutive impacts, without the bag passing through them.
Grids for hatches come in 4 sizes: 600 × 600, 800 × 800, 1,000 × 1,000 and 1,500 × 800 mm. Each one is compatible only with the T1-Std hatch of the same size.
With the civil works module: 2 L.1200 bars to cut to size on site, spaced 200 mm apart, mounted on GRP angles. The modules combine to cover the full width of the opening.
Just one. Once opened, the grid drops back automatically into the closed position; the stainless steel comb handles locking and alignment.
Yes. Composite is chemically inert to H₂S, chlorine, ozone and saline atmospheres: in wastewater treatment plants, valve chambers or coastal sites.
So they can be seen. The GRP bars are yellow, coloured right through: the colour doesn’t flake off.
