Performance & Compliance

Rectangle rainheads create a vertical buffer (“drop”) between box gutter and down-pipe, preventing overflow within the building under heavy rainfall. The overflow weir must be positioned 25 mm below the gutter sole, with width matching the rainhead inlet to meet Australian standards (AS/NZS 3500.3:2003).

Constructed from 0.55 mm BMT Colorbond® or Zincalume® steel, the rainhead ensures superior durability, corrosion resistance and a long service life under harsh weather conditions.
