"Pre-galv. pipes" refers to pipes that have undergone a galvanization process before they are used in various applications. Galvanization is the process of applying a protective layer of zinc to steel or iron to prevent rust and corrosion. When pipes are pre-galvanized, they are coated with zinc before they are formed into pipes, ensuring that the entire surface, both inside and outside, is protected. This provides excellent corrosion resistance and durability to the pipes, making them suitable for various uses.

Welded steel pipe is widely used in many industries due to its low production cost, high production efficiency, varieties of specifications and stypes, simple production process.

Construction industry is one of the most dynamic and constantly evolving sectors in the world. The demand for new and innovative building projects is always high, and to meet this demand, builders and architects are always on the lookout for newer and better materials. One such material that has gained immense popularity in recent years is pre-galvanized hollow section.
