T&D distribute the complete range of Earth Bosses that are designed to provide an earth connection point on a steel structure – the boss is welded onto steel vessels, tanks and other structures.
The earth bosses are manufactured from mild steel with stainless steel fittings – the earth boss size, material type and design configuration can be designed to accept onshore or offshore project applications.
Stainless steel earth boss manufactured from marine grade type SS316L can be be produced for corrosive applications in offshore applications including wind turbine base foundations where sea water splash, submersion and general exposure would cause rusting and oxidisation of standard mild steel type bosses.
As standard earth bosses are supplied with fixing bolts, flat washers and spring washer.
Where earth connection points are required in concrete structures and welding earth bosses is not a viable option then earth bonding points manufactured from Gunmetal can be installed.
Thorne & Derrick stock and distribute the complete range of Copper Earthing Products manufactured by AN Wallis.
Earth bosses can be produced as standard in a range of dimensions and also customised to client specification and requirement – standard thread size is M10. Mild steel and stainless steel material available.
