Q235 Galvanized Steel Coil Advantages

1. Excellent Corrosion Resistance: The zinc coating effectively isolates the base material from air and moisture, significantly improving the steel’s corrosion resistance. Compared to ungalvanized Q235 steel, its service life can be extended by 3-5 times, making it especially suitable for humid, outdoor, or mildly corrosive environments (such as building facades, livestock farms, and pipe supports).
2. Excellent Processing Performance: Inheriting the plasticity advantages of Q235 steel, it can undergo various processing operations such as shearing, bending, stamping, and welding. It can be manufactured into different forms of products such as plates, profiles, and pipe fittings according to needs, adapting to diverse production scenarios.

3. High Cost-Effectiveness: The Q235 base material itself has a low cost, and the galvanizing process is mature and cost-effective due to large-scale production. Compared to materials such as stainless steel and aluminum alloys, it offers a more competitive price while meeting basic anti-corrosion requirements, making it an ideal solution for “low cost + long service life.”

4. Stable Mechanical Properties: The zinc layer thickness is typically 50-100 g/㎡ (double-sided), which does not significantly affect the core mechanical properties of Q235 steel, such as yield strength and tensile strength, ensuring the load-bearing safety of structural components.
