The dimensions of the angle iron must be at least 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel
tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).
Weld the yellow-green grounding cable to the angel iron or steel tube and use cathodic protection to
protect the joint from corrosion.
