Authentic Steel is a premier global PPGI steel sheet supplier, manufacturer, and exporter of high-durability PPGI / PPGL steel sheet and color coated steel sheet products engineered for severe architectural, industrial, and agricultural environments. Combining the structural strength of steel with advanced organic paint systems, our prepainted galvanized steel sheets (PPGI) and prepainted galvalume steel sheets (PPGL) strictly conform to international engineering standards including ASTM A755/A755M, JIS G3312, EN 10169, and GB/T 12754.
While PPGI features a hot-dip galvanized substrate for cost-effective corrosion resistance, PPGL incorporates a 55% aluminum-zinc alloy substrate that delivers up to four times the atmospheric durability, making both options ideal long-term solutions for modern building enclosures.
Substrate & Coating Mass: Hot-Dip Galvanized Substrate (PPGI: Z30–Z275) or Galvalume Substrate (PPGL: AZ30–AZ150)
Dimensional Range: Thickness from 0.12 mm to 0.80 mm; Width from 600 mm to 1,250 mm; Custom cut-to-length sheet leveling
Paint Coating Thickness: Top coat 15–25 µm, back coat 5–12 µm applied via dual-coat / dual-bake continuous lines
Color & Aesthetic Variety: Full RAL color matching, specialized textures (matt, wrinkle, high-gloss, wood/brick patterns), optional 30–80 µm PE protective film
International Grade Reference: Commercial Quality (DX51D+Z/AZ, CS Type A/B, CGCC) and High-Strength Structural Quality (S280GD–S550GD, Grade 33–80)
Standard Compliance: ASTM A755, EN 10169, JIS G3312, GB/T 12754 supported by EN 10204 3.1 Mill Test Certificates
Our continuous color-coating lines apply premium organic paint systems engineered to withstand intense UV radiation, chalking, and chemical degradation:
Regular Polyester (PE): Economical choice with high formability and adhesion for standard interior and exterior panels.
High-Durable Polyester (HDP): Superior UV retention, thermal resistance, and anti-fading performance for tropical and high-radiation regions.
Silicon Modified Polyester (SMP): High surface hardness and abrasion resistance for dusty industrial environments.
Fluorocarbon (PVDF): Ultimate atmospheric defense providing 20+ years of maintenance-free service in aggressive coastal and marine settings.
Driven by exceptional mechanical formability, lightweight design, and vibrant aesthetic options, our prepainted steel sheets serve vital roles in modern global infrastructure:
Architectural Roofing: Cold-formed into high-tensile color coated metal roof panel for building structures, prefabricated warehouses, industrial factories, and livestock housing.
Exterior Facades: Heavily specified as architectural PPGL sheet for wall cladding, decorative facades, interior partition panels, and sandwich panel face sheets.
Drainage & Accessories: Processed into weatherproof rainwater gutters, downspouts, flashing, and architectural trims.
Appliance & Cleanroom Use: High-precision flat sheets for cleanroom partitions, ceiling panels, cold room enclosures, and home appliance bodies.
Quality control is embedded throughout our manufacturing workflow. Every batch undergoes comprehensive laboratory verification, including paint coating thickness checks, T-bend flexibility testing (0T–2T), cross-hatch adhesion trials, and neutral salt spray chamber tests. Material Test Certificates (MTC EN 10204 3.1) and third-party pre-shipment inspection reports (SGS, Bureau Veritas) are provided standard with every order.
To ensure maximum protection during long-distance maritime shipping, all shipments are secured in heavy-duty ocean export packaging: moisture-proof plastic wrapping, anti-corrosive VCI paper, protective steel edge rings, and heavy steel strapping anchored on seaworthy wooden pallets.
