Are you looking for an upgraded architectural solution that provides double the corrosion resistance of standard pre-coated metals in harsh industrial or marine environments? Prepainted Galvalume Steel Coil (PPGL) is the premier choice for elite engineering projects. Featuring an advanced aluminum-zinc alloy substrate, our color-coated galvalume solutions offer unparalleled sacrificial protection and structural longevity. Authentic Steel is your dedicated factory-direct partner, delivering high-performance color-coated metal coils straight from Tianjin to global industrial centers.
Every batch of our prepainted aluminum-zinc alloy coil is meticulously engineered to achieve exceptional paint bonding capability and continuous thermal reflectivity, matching international criteria:
Thickness Range: 0.085mm – 1.4mm (Perfectly engineered for commercial roofing sheets, purlins, and premium cladding panels)
Width Options: 900mm – 1250mm, or customized according to specific regional standards.
Color Customization: Fully synchronized with the universal RAL Color Chart, or precisely duplicated based on customer-supplied paint coupons.
Advanced Coating Types: Available in high-performance PE, SMP, HDP, and PVDF paint formulas designed to sustain severe atmospheric exposure.
Coating Thickness: Top Side: 5 – 35 Microns | Back Side: 5 – 20 Microns.
Unit Coil Weight: 3 – 24 Tons.
Coil Internal Diameter (ID): 508mm / 610mm.
Global procurement directors and premium metal fabricators prefer Authentic Steel PPGL products because they deliver enhanced performance in extreme settings:
Superior Al-Zinc Corrosion Barriers: The 55% aluminum, 43.4% zinc, and 1.6% silicon alloy substrate provides a dual barrier. Combined with our HDP/PVDF paint coatings, it yields supreme resistance to rust creep at cut edges, even in humid tropical zones or heavy industrial regions.
Excellent Heat Reflectivity & Energy Efficiency: The underlying galvalume layer naturally reflects a high percentage of solar radiation. When combined with our specialized cool-roof paint pigments, our PPGL steel coil helps reduce building cooling costs globally.
Outstanding Fabricability: Despite its dense alloy barrier, the coating remains highly ductile. It withstands complex stampings, tight structural lock-seaming, and profiling without suffering microscopic paint delamination.
Operating under the corporate umbrella of AUTHENTIC (TIANJIN) I AND E LTD, we offer direct access to massive industrial capacities and wholesale pricing structures. We minimize your supply chain risks by ensuring that all cargo meets mainstream testing requirements and is backed by thorough technical documentation.
Heavy-Duty Maritime Shipping Protection: To protect the unique surface brilliance of our PPGL steel coil shipments during transoceanic transit, each coil is enveloped in premium heavy-duty waterproof wrapping and secured within rigid steel protective outer casings. This eliminates salt-air contamination and mechanical chafing.
