On Concrete Slab Style
For on-concrete applications the legs of an inground style stringer are cut to the desired length, next a bolt-on stair kit bracket is screwed to each leg. The stringer legs are then able to be anchor bolted down into place. (A bolt-on stair kit consists of 2 angle brackets and tek screws for fixing to the legs).
Standard stringers are fabricated with a Rise of 175mm and a Going of 250mm. Stair Stringers, generally available as a pair, come complete with top hanger brackets & riser brackets The stringers are supplied in 2 different finishes SUPAGAL
All Stringers are fabricated from Australian Made 100 x 50 x 3.0mm Supagal RHS. This product is a pre-galvanized (both inside and out) grade AS1163 - C350/450LO material. The total coating thickness of Supagal pre-galvanized sections is twice that of any other product currently available. On Supagal Stringers all the welds and brackets are then coated with Cold Galvanized Paint after fabrication. These units are normally then painted HOT DIPPED GALVANISED (HD GAL)
Should you require extra protection from the elements, then we recommend using Hot Dip Galvanized Stringers. Hot Dip Galvanizing is a process where the stringer, after manufacture, is completely immersed in molten zinc. This thick metallic zinc coating, that completely covers the stringer surface, providing a superior corrosion resistant finish. There is no need to paint these units but can be if required.
