Black iron galvanization is an economical and highly durable surface treatment technique, ideal for iron components requiring long-term oxidation and corrosion resistance. Through galvanization, black iron forms a compact protective layer on its surface, enhancing rust resistance and boosting its sheen. Compared to using pre-galvanized steel sheets, black iron with post-galvanization offers better flexibility in processing at a more affordable price. Pre-galvanized sheets are surface-treated before leaving the factory, which limits precision processing options and typically costs more.

In this project, we used black iron, applying custom 2D laser cutting, threading, and countersinking before galvanization, resulting in a product that is both visually appealing and highly functional.

Shangbang Steel is dedicated to providing professional, high-quality black iron galvanization services. From laser cutting and threading to countersinking, our skilled team manages every step. Our precise 2D laser cutting technology meets diverse client needs, while galvanization enhances the product’s appearance, making it brighter and more rust-resistant with lasting durability and high value.
