Moulded GRP Stairtreads
Product information
Moulded GRP stairtreads are manufactured with a closed, corundum gritted and black coloured (optional yellow) safety nosing. Due to the colour the nosing is clearly visible.
Depending on span, load and required deflection limit, the GRP-stairtread can be supplied with a responding safety nosing type.
The types range from standardized laminated GRP flat sheets, over massive mesh sizes to laminated GRP angle profiles and is to be discussed.
There is a range of different surfaces. The surface of the in-stock GRP-stairtreads is corundum-gritted (KB).
Please consider our explanations regarding anti-skid properties.
GRP stairtreads with screw-on angle side-plates made of GRP or stainless steel grade 1.4301/AISI304 and 1.4571/AISI316 are available on demand.
