STEEL WIRES

Kromtel carbon steel wires are produced from finest wire rods. These wires are adequate for flattening use and will neither burst nor crack.

Carbon steel wires are mainly used for springs and mattresses, other than those mentioned it is also used for other woven applications; woven cage productions, CO2 welding wires, zig-zag spring wires, music wires and rope wires.

Our products comply with global standards and have quality certificates issued by institutions like ISO and TÜV.
