Our thickened galvanized Q235B perforated angle iron, available in 40*40 specifications, includes double universal and unequal designs, ideal for diverse structural needs. The robust Q235B steel core, combined with a thick galvanized layer, delivers exceptional corrosion resistance and durability, ensuring long-term performance in harsh environments. Precisely punched holes facilitate quick installation and versatile connections, eliminating the need for on-site drilling. With excellent weldability, these angle irons enable strong, secure joints, enhancing structural stability. Whether for frameworks, supports, or bracings, their universal design adapts to various applications, making them a reliable choice for construction and industrial projects.
Stable mechanical properties: It has a minimum yield strength of 235 MPa and good tensile strength (375-500 MPa), ensuring the angle iron can bear static loads (such as building supports) and moderate dynamic loads without deformation or fracture.
Good weldability: Low carbon content makes it easy to match with common welding methods (e.g., arc welding, gas shielded welding). Weld joints have high strength and are not prone to cracks, which is critical for subsequent assembly and structural connection.
Cost-effectiveness: As a widely used standard carbon steel, Q235B balances performance and cost, making the product suitable for large-scale construction or industrial batch applications.
The "thickened" feature directly targets scenarios requiring high structural stability:
Increased section thickness: Compared with ordinary thin-walled angle iron, its thicker web and flange (the two right-angle sides) significantly improve the section modulus and moment of inertia. This means it has stronger resistance to bending, torsion, and compression.
Extended service life under heavy load: For applications like heavy equipment supports, building truss nodes, or mechanical frames, the thickened structure reduces fatigue damage caused by long-term stress, avoiding premature deformation.
Galvanization is a key process to improve the durability of carbon steel angle iron, especially in harsh environments:
Zinc layer protection mechanism: The surface is coated with a uniform zinc layer (hot-dip galvanizing is commonly used for thickened products). Zinc acts as a "sacrificial anode"—it corrodes first to prevent the underlying Q235B steel from rusting due to contact with moisture, oxygen, or corrosive media (e.g., rainwater, industrial fumes).
Wide environmental adaptability: Suitable for both indoor dry environments (e.g., workshop shelves) and outdoor/humid scenarios (e.g., outdoor billboards, construction scaffolding, or water treatment equipment frames), effectively extending the product’s service life to 10-20 years (depending on the environment).
Low maintenance cost: The galvanized layer has good wear resistance and does not require frequent painting or anti-rust treatment, reducing long-term maintenance expenses.
