Spouting Support Systems
The spouting bracket system must withstand the potential weight of a gutter full of water. In snow load areas, spouting may be fitted with snow straps and brackets at a maximum of 600 mm centres to withstand the additional potential weight of any snow build-up.
Brackets should be made of compatible material or non-ferrous metal. Brackets for unpainted spouting should be hot dipped or galvanised, or have an AZ150 or Z450 or equivalent coating. Unpainted Z275 brackets are not acceptable nor are painted or unpainted electro-plated brackets. Brackets for pre-painted spouting must be painted or powder-coated before installation, where required. In severe marine areas, brackets should be epoxy primed before powder coating or should be formed from non-ferrous metal.
Brackets for external gutters should be located close to all stop-ends, at both ends of sumps and rain-heads at a maximum of 750 mm spacing for gutters less than 180 mm wide, and at 600 mm for gutters 180 – 300 mm wide. Brackets must be installed to provide a 1:500 (2 mm per metre) minimum gutter gradient towards the outlets.
