The inground foot style is the most popular form of stringer. After bolting the top hanger brackets into place, the base of the stringer is simply concreted into a suitable hole in the ground. The leg on the stringer is approximately 350mm long, a cross bar is welded to the leg to assist in holding into the concrete footing.
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 insiide 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 you install the stairs
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.
