Black iron refers to steel that has not been coated or treated, giving it a dark appearance. It is primarily used in applications that require strength and durability. While black iron is strong, it is susceptible to rust and corrosion when exposed to moisture and air. To overcome this limitation, galvanization is employed. This process involves coating the black iron with a layer of zinc, which protects the steel from corrosion and extends its service life.

4. Pricing and Minimum Orders Assess the supplier’s pricing structure and minimum order quantities. Finding a supplier who offers competitive pricing without compromising on quality is essential for budget-conscious buyers.

The galvanization process typically involves hot-dip galvanizing, where the malleable iron components are submerged in molten zinc. This method forms a robust bond between the zinc and iron, resulting in a thick, protective layer that shields the metal from corrosion. Manufacturers often employ stringent quality control measures to ensure that the galvanization process is performed correctly, as any defects can compromise the integrity of the protective layer.

After rolling, the sheets undergo a series of treatments, including coating and painting, to enhance their appearance and durability. These coatings often include weather-resistant finishes that provide additional protection against rust and UV radiation.
