Description
inc-Aluminum-Magnesium (Zn-Al-Mg) Square Pipes are high-performance square hollow sections (SHS) made from carbon steel and coated with an advanced alloy layer of zinc, aluminum, and magnesium. This innovative coating technology offers significantly enhanced corrosion resistance compared to traditional galvanized steel, making these pipes ideal for long-term use in outdoor and harsh environments.
Manufactured from high-quality steel such as Q195, Q235, or Q355 through precision forming processes, Zn-Al-Mg square pipes provide excellent structural strength, dimensional accuracy, and durability. They are widely used in construction, infrastructure, and photovoltaic (PV) mounting systems.
