Product information
Moulded GRP stairtreads are supplied with a closed, corundum-gritted safety nosing (black standard, yellow optional) to increase visibility of the tread front. Panels are manufactured for stair and platform use and can be adapted to span, load and allowable deflection.

Characteristics / technical specifications

• Material: moulded GRP (glass-fibre reinforced plastic).
• Closed, corundum-gritted safety nosing (black standard, yellow optional) for improved visibility and slip resistance.
• Surface options: several anti-slip finishes; stock surface = corundum-gritted (KB).
• Construction variants: laminated GRP flat sheets, massive mesh formations, laminated GRP angle profiles — selected according to span and load.
• Side plates: GRP or stainless steel (1.4301 / AISI304 and 1.4571 / AISI316) available, fixed by bolting.
• Typical geometry: H = 38 mm; bar thickness Su/So = 5/7 mm; mesh spacing = 38.1 x 38.1 mm; open mesh ≈ 31 x 31 mm.
• Weights and stock sizes: examples provided in technical tables above.
• Please consult product-specific anti-slip information when specifying.
