Authentic Steel offers high-definition printed prepainted galvanized steel coils engineered as an innovative, sustainable alternative to natural building materials. By transferring detailed graphic patterns directly onto prime zinc-coated steel substrates using automated multi-tone rotogravure printing technology, these coils achieve realistic visual textures including natural wood grains, classic masonry brickwork, granite stone, and military camouflage patterns.
Incorporating printed steel coils into modern exterior cladding and interior design eliminates common maintenance drawbacks associated with natural materials, such as moisture rot, termite vulnerability, flammability, and high structural weight. Combining the high tensile strength and rust resistance of hot-dip galvanized steel with UV-inhibited clear topcoats, our patterned PPGI coils deliver vibrant aesthetics, fire safety, and long-term durability for residential, commercial, and industrial architectural projects.
Standard Visual Patterns: Classic Oak, Natural Teak, Dark Walnut, Red Clay Brick, Weathered Stone, Marble, Forest Camouflage, Desert Camouflage, and Customized Graphic Motifs
Surface Finish Variations: Smooth Matt, High-Gloss Clear Varnish, or 3D Tactile Embossed Grain
Topcoat Protective Layer: 5to 35 microns of weather-resistant clear fluorocarbon or high-durability polyester varnish
Base Metal Substrate: Hot-Dip Galvanized Steel (Z20 to Z275 g/m²) or Galvalume Steel Substrate (AZ20 to AZ150 g/m²)
Thickness Range: 0.085 mm to 1.40 mm
Standard Widths: 750 mm, 914 mm, 1000 mm, 1200 mm, 1219 mm, 1250 mm, or slitted narrow strips
Applicable International Standards: ASTM A755, EN 10169, JIS G3312 CGCC, GB/T 12754
Building Envelopes & Exterior Wall Siding: Used in residential villa wall panels, modular house facades, garage door skins, and decorative soffits that mimic timber or brick without heavy foundation loading.
Interior Decor & Partitioning: Applied in office partition systems, decorative suspended ceiling tiles, elevator interior linings, and cleanroom wall panels.
Security Doors & Commercial Furnishings: Formed into fire-rated security doors, indoor metal doors, office filing cabinets, and commercial display shelving.
Specialized & Military Facilities: Used in field shelters, military equipment enclosures, perimeter fencing, and camouflaged storage units.
High Resolution & Color Consistency: Advanced rotogravure rollers ensure sharp graphic details, natural color gradients, and seamless pattern repetition across long coil runs.
Formability Without Image Distortion: Thermally cured flexible ink layers bond tightly with the conversion coat, allowing severe roll-forming, deep drawing, and tight-angle bending without cracking or pattern stretch marks.
Fireproof & Low Maintenance: Non-combustible steel substrates provide Class A fire performance while the smooth clear varnish layer repels dirt and allows easy cleaning with water.
