Custom Galvanized Steel Frame and Structure Applications: Durable Solutions for Industrial Excellence
CAFU Machinery specializes in custom galvanized steel fabrication, delivering robust and corrosion-resistant solutions for industries that demand longevity and reliability. Our galvanized metal structures are engineered to be widely used in harsh environments, from coastal facilities to heavy industrial plants. With advanced hot-dip galvanizing processes and precision fabrication, we create galvanized steel frame, platforms, beams.
Why Choose Hot-Dip Galvanized Steel Structures?
Hot-dip galvanizing (HDG) is the gold standard for corrosion protection, offering 25+ years of service life with minimal maintenance. Our process ensures:
1. Superior Zinc Coating: ≥275g/m² (exceeding ISO 1461 requirements)
2. Full Penetration Protection: Zinc bonds metallurgically to steel, covering edges and welds uniformly
3. Environmental Resistance: Withstands salt spray, humidity, and chemical exposure
Our Galvanizing Process: Extra-large hot-dip galvanizing tank ensures that welded parts are galvanized in their entirety to ensure the quality of the galvanized layer
1. Pre-Treatment:
• Degreasing: Alkaline cleaning removes oils and contaminants
• Acid Pickling: Eliminates mill scale and rust (HCl or H₂SO₄)
• Fluxing: Zinc ammonium chloride prepares surfaces for galvanizing
2. Hot-Dip Galvanizing:
• Immersion in molten zinc at 450°C (842°F)
• Formation of zinc-iron alloy layers (delta and zeta phases)
3. Post-Treatment:
• Passivation with chromium-free passivation solution to minimize environmental contamination
