Asbra Safety Stair Treads & Nosings
Filled with slip-resistant Suregrip and Supagrit silicon carbide mineral granules for heavy and light duty applications. Service factors must be taken into consideration when selecting stair tread profiles.
All Asbraloy and Asbrabronz profiles are offered factory cut to the site required length (up to 4600mm in 1 continuous length) complete with countersunk holes, stainless steel or brass screws (depending on the selected section) and plastic plugs. If specified at time of order treads can be supplied in full manufacturing lengths of 4600mm for on site cutting and drilling to suit clients supplied fixings. All Asbraloy and Asbrabronz Safety Stair Tread Nosings are discreetly stamped on the surface close to one end “as manufactured by Latham Australia”, which ensures installed material can be identified in the future and is the clients confirmation that the specified product has been installed.
Factory Cutting Tolerance: +0/-3mm.
Screw Fixing Holes
Unless otherwise specified at time of order, holes will be provided in the treads to suit 8 gauge stainless steel or brass screws (see page 4 of Stair & Flooring Catalogue 13 for further detail) at Latham’s standard 250mm centres. Any special machining, mitering, modifications or alternative hole locations, will be carried out at extra cost.
