Originally made by hand, these are now produced by Gridiron using highly technological and entirely automated systems that ensure high quality levels.
The iron bars, 50 mm high and 4 mm thick, are notched and then crossed by 10 mm diameter round iron bars to create a mesh of 30x50 mm.
The resulting grating is then hot-dip galvanised. Withstands the strongest pressures.
Each drain cover comes complete with hot-dip galvanised frame, 3 mm thick.
