Alispar

Alispar Nosings and Treads are designed to take heavy foot traffic and are suitable for use on external stairs where a high degree of slip resistance is required, even in wet conditions.

They are manufactured to order from high quality tensile aluminium and come fully assembled and drilled for fixing

Typical applications are Railway Station Footbridges and Subways, Hospitals, Schools and High Rise Housing blocks.

Fixing Recommendations

For fixing onto stone or concrete stairs, ensure that surface is sound and level. Make good any worn or broken areas with rapid cement or epoxy repair mortar.

Position Alispar on step. Spot through to mark with a 4mm dia masonry drill. Lift off Alispar and drill 6mm dia hole where indicated to take a red plug. Apply a layer of bedding compound (e.g. exterior grade tile adhesive) to step and relay Alispar. Screw down with 4mm dia stainless steel countersunk screws.

For steel stairs position Alispar on step, spot through with 4mm HSS drill bit. Lift Alispar off and drill steel through with 5mm HSS bit. Apply layer of insulation membrane (e.g. Bituthene). Use Countersunk machine screws, nyloc nuts and washers to fix.

For timber stairs ensure surface is flat and level. Use 4mm woodscrews.
