Galvanized square tubing is a type of hollow, cold-formed steel section with a square or rectangular profile. It is manufactured from hot-rolled or cold-rolled strip steel or coils through cold-forming and high-frequency welding, followed by a galvanizing process for surface corrosion protection. Common specifications range from 20\u00d720 mm to 600\u00d7600 mm, with wall thicknesses between 0.8 mm and 40 mm and typical zinc coating weights of 60\u2013275 g\/m\u00b2. Characterized by a uniform structure and a high section modulus, these tubes offer superior bending resistance and load-bearing capacity compared to round tubes of the same weight, while also facilitating easier positioning and assembly.<\/p>\n

Hot-dip galvanized square tubes: Produced by immersing formed square tubes into molten zinc, these feature strong zinc adhesion and long-lasting corrosion resistance; they are suitable for highly corrosive outdoor environments and represent a mainstream choice in construction projects.<\/p>\n

Electric galvanized (cold-galvanized) square tubes: Produced by depositing a zinc layer onto the tube surface via an electric chemical process, these feature a uniform, smooth coating and lower zinc consumption; they are better suited for dry indoor environments where a high-quality surface finish is required.<\/p>\n

Square tubes made of ordinary carbon steel (such as Q195 and Q235) and low-alloy steel (such as Q345) can be flexibly selected based on the structural load requirements.<\/p>\n

As a core material in steel construction, it is used to erect primary steel beams and columns, as well as roof and floor support frameworks, serving as a common structural material for large-span industrial plants and public venues.<\/p>\n

Widely used in the primary and secondary framing for glass curtain walls; its uniform cross-section allows for the direct attachment of curtain wall mounting hardware, significantly enhancing construction efficiency.<\/p>\n

Used in photovoltaic mounting systems for building-integrated photo voltaic (BIPV), outdoor architectural railings, municipal street light poles, and structural supports for enclosures at airports and transportation hubs.<\/p>\n
