TCB’s were a British concept but found popularity first in the Far East and then the USA. The bolt has now established a firm foothold in the UK structural steel industry and throughout Europe. The TCB is widely replacing HV & HR high strength friction grip bolts and nuts due mainly to its speed of installation and quality advantages.
Tension Control Bolts Ltd pioneered the Greenkote® coating system it was probably the most significant moment in the company’s history. With corrosion protection being high on the engineers list of priorities, Greenkote, with its natural advantages, instantly revolutionised the coating of threaded fasteners
Today, tension control bolts are used around the world in the construction of Wind Energy Towers as well as Nacelle, Flange & Jacket connections. TCBs are the first choice for engineers who demand the highest standards of bolting integrity.
