Sheet Metal parts made from Galvanized steel & …

Product Details: Sheet metal parts can be made from either raw steel (CRS) or pre-galvanized steel. HY Metals offers various finish options, including Zinc plating, nickel-plating, chrome-plating, powder-coating, and E-coating. For corrosion-resistant coatings, Pre-galvanized and Zinc plating are the two main options. Pre-galvanizing involves applying a thin layer of zinc to the steel before fabrication, while Zinc plating applies a layer of zinc to the steel after it is formed into a sheet metal part. This latter method ensures complete coating, including cut edges.

Pros:
– Pre-galvanizing is often a lower cost option and allows for greater flexibility…
