Advantages of N galvanized square tube

Galvanized square tube has the dual advantages of rust prevention, durability, and economic practicality: its surface hot-dip galvanized layer (thickness ≥ 65 μ m) forms a dense protective film, and its corrosion resistance is 5-8 times higher than ordinary steel pipes, extending its service life to more than 20 years; The square structure has strong bearing capacity, which is 15% -20% higher than that of circular pipes, and is suitable for load-bearing scenarios such as building frames and mechanical supports; The zinc layer is metallurgically bonded with the steel substrate, which is scratch resistant, impact resistant, and suitable for harsh outdoor environments; And zinc resources can be recycled and reused, which meets the standards of green building materials. The comprehensive cost is reduced by 40% compared to stainless steel, making it a cost-effective structural material. ews
