GALVANIZED SHEET AND COILS
Due to its quality, it is the ideal material for a wide variety of uses; the steel sheet galvanized by the hot dip process and an annealing process provide the highest quality in terms of coating, surface and stamping ability.
In addition, there are the best quality controls with specialized measurements such as the thickness of black sheet based on gamma rays, zinc coating through automatic X-ray calibrators, in addition to mechanical testing and chemical analysis of zinc required by the customer.
