FAQ: Industry Terms & Technical Questions

1. What is the major material used in zinc steel fences?: Galvanized Low-Carbon Steel (Q195/Q235): provides optimal balance between tensile strength and anti-rust capability, further protected by zinc-rich coatings per ASTM A653.
2. What are the common surface treatment standards?: Double-layered coating—zinc rich primer followed by polyester powder finish (EN ISO 1461, 14713), exceeding 1000h neutral salt spray for superior outdoor oxidation resistance.
3. How does panel thickness affect security and durability?: Standard thickness ranges from 1.0mm–2.5mm; thicker panels result in higher mechanical impact strength, critical for industrial/utility perimeter security, measured by Charpy impact testing (ISO 179/180).
4. Is the welding process certified?: Yes, our zinc steel fence uses robotic MIG welding, inspected per ISO 3834—with documentation of visual/dimensional tolerance and mechanical seam strength testing (≥450MPa shear strength).
5. What installation standards do you follow?: Compliant with ISO 1461 for galvanizing and EN 1090/ISO 9001 for mechanical/joint tolerances. Site installation manuals and training provided.
6. How is anti-corrosion life tested?: Via accelerated salt-spray (ISO 9227, ASTM B117), UV-exposure (ASTM G154), and natural field aging simulation. Panel remains rust-free ≥20 years in most environments.
7. Can fences be customized for aesthetics and branding?: Absolutely. Offers customizable RAL/Pantone colors, cap/tip styles, laser-cut patterns, and logo integration—supporting landscape architects and branding projects.
