Stainless steel step STAIRTREADS

GRPcorundum316 stainless steel

Product information
Moulded GRP stairtreads are manufactured with a closed, corundum-gritted safety nosing in black (optional yellow). The coloured nosing improves visibility of the leading edge.
The nosing design can be adapted according to span, load and required deflection limit. Variants include standardized laminated GRP flat sheets, massive mesh configurations and laminated GRP angle profiles; the appropriate type is to be agreed per project.
Various surface finishes are available. The standard stock surface is corundum-gritted (KB).
GRP stairtreads with screw-on angle side-plates in GRP or stainless steel (grade 1.4301/AISI304 and 1.4571/AISI316) are available on request.
Please refer to guidance regarding anti-skid properties.
