Authentic Steel supplies premium Anti-Fingerprint Galvalume Steel Coils (AFP GL Coils) featuring a high-performance organic acrylic or inorganic chemical sealing layer applied over a 55% Aluminum-Zinc alloy coating. The specialized resin treatment prevents fingerprint smudging, surface oxidation, and transit moisture staining, while significantly improving lubricity during continuous cold roll-forming and stamping processes.
Available in Transparent (Clear), Green, Blue, Gold, and Custom Tinted Finishes, AFP galvalume steel coils offer an aesthetically pleasing, smooth surface appearance combined with superior atmospheric durability. The anti-fingerprint coating bonds chemically with the Al-Zn alloy substrate, serving as both a protective barrier against hand sweat and minor scratches and an ideal bonding primer if post-painting is required.
AFP Coating Color Options: Transparent Clear (Natural Metallic Silver), Sea Blue, Jade Green, Golden Tint, or Customized Chromate-Free Organic Resins
Alloy Coating Mass: AZ20 to AZ180 (55% Aluminum, 43.4% Zinc, 1.6% Silicon dual-sided continuous hot-dip layer)
Thickness Range: 0.1mm to 3.5mm precision gauge control
Width Availability: 600mm, 752mm, 914mm, 1000mm, 1200mm, 1219mm, 1250mm, or custom slitted strips
Substrate Mechanical Grades: Commercial Quality (CQ / DX51D+AZ), Structural Quality (S350GD+AZ, S550GD+AZ / G550 Full Hard)
Compliance Standards: ASTM A792 / A792M, EN 10346, JIS G3321 (SGLCC), GB/T 14978
Architectural Roofing & Wall Cladding: Widely processed into Spandek roof profiles, standing seam panels, and architectural wall cladding sheets where aesthetic cleanliness and vibrant tinted finishes are required.
Home Appliances & HVAC Cabinets: Used in refrigerator back plates, microwave oven internal chassis, washing machine side panels, air conditioner outdoor units, and ductwork enclosures.
Electrical Enclosures & Structural Channels: Ideal for cable trays, distribution box housings, light steel framing, and electrical junction boxes exposed to frequent handling during assembly.
Deep Drawing & Roll-Forming Applications: The self-lubricating resin film reduces tool wear and eliminates the need for stamping oils during complex profiling.
Superior Resistance to Handling & Moisture: The acrylic seal layer shields the reactive zinc-aluminum surface from sweat, oil, atmospheric oxidation, and black-spot corrosion during storage and installation.
Self-Lubricating Roll-Forming Performance: The surface resin acts as a dry lubricant, preventing sheet binding, die galling, and coating abrasion during high-speed roll-forming lines.
Export-Grade Seaworthy Packaging: Every coil is packaged with multi-layer VCI anti-rust paper, protective inner plastic wrapping, heavy outer steel drums, corner protectors, and high-tensile steel straps on sturdy wooden skids.
