Authentic Steel manufactures and exports high-performance High Durability Polyester (HDP) and Polyvinylidene Fluoride (PVDF / Fluorocarbon) PPGI steel coils engineered specifically for aggressive chemical atmospheres, extreme solar UV radiation, and high-salinity coastal environments. Utilizing continuous automated multi-layer coil coating lines, premium hot-dip galvanized steel substrates are treated with complex chemical passivation layers, heavy anti-corrosive primer coats, and advanced HDP or Kynar 500® PVDF topcoats.
High Durability PPGI steel coils represent the pinnacle of architectural coil coating technology. Designed for monumental public structures, industrial landmarks, and heavy chemical installations, HDP and PVDF painted coils provide exceptional gloss retention, color stability, anti-chalking endurance, and chemical resistance, guaranteeing a maintenance-free service life exceeding 20 to 30 years.

Major Transportation Hubs & Public Buildings: Widely specified for international airport terminal roofs, high-speed railway station canopies, convention centers, and stadium envelopes.
Coastal Infrastructure & Seaport Facilities: Ideal for seaside industrial parks, marine storage hangars, port logistics warehouses, and desalting plant structures exposed to salt spray.
Heavy Industrial & Chemical Plants: Utilized in power stations, chemical processing plants, fertilizer storage facilities, and smelting plants exposed to acid fumes and industrial emissions.
High-End Commercial Façades: Applied in architectural curtain wall panels, metallic cassette cladding, and standing seam roof systems requiring long-term aesthetic fidelity.
Unrivaled UV & Chemical Resistance: The fluorocarbon carbon-fluorine molecular bond in PVDF topcoats possesses extreme chemical stability, resisting degradation from harsh solar radiation, acid rain, and airborne industrial pollutants.
Zero Chalking & Superior Color Retention: Engineered to maintain original color intensity and gloss level over decades, preventing chalking, surface cracking, or film erosion even in equatorial and high-UV desert climates.
Seaworthy Protective Packaging: Every coil is wrapped with VCI anti-rust paper, protective inner plastic wrapping, outer steel drums, heavy corner protectors, protective PE film, and high-tensile steel banding on reinforced wooden skids.
