Aluminized steel wire, diameter 2.0 mm.

Protective coating structure:

Series of layers of aluminium-iron alloys formed on the surace of the wire with successively higher aluminium content towards the coating surface and intermetallic layer towards inner center.
The protection layer do not have hydrogen embrittlements.

Properties of the protective coating:

Density                                                              66.68 g/m²

Thickness of aluminium layer                      20 μm

Thickness of intermetallic layer                   4  μm


Trimetal ( Aluminium, Zinc and Lead) Continuous Galvanising Line for coating of steel wire is application of the ThermoGreen technology.

Presented Line instalation provides coating with Aluminium and Aluminium alloys, but can be easily converted into coating with Zinc, its alloys or Lead-Tin.

Presented line is desined to demonstrate to operators of existing galvanising lines benefits of efficiency, flexibility and superior quality of the final protective coating at lower cost.

The qualities of the final product certified by independent laboratories.

Base material:

Wire:                                                                black steel wire, carbon content 0.1 – 0.8%
