Technical Specifications of Prime Color Prepainted Galvanized Steel Coil

Prime Color Prepainted Galvanized Steel Coil - High-Adhesion PVDF Coating

Prime color prepainted galvanized steel coil represents a premium-grade metal substrate that combines galvanized steel protection with factory-applied organic coatings, delivering exceptional durability for architectural and industrial applications. Engineered with advanced PVDF resin systems, this coated steel product offers superior color retention, weathering resistance, and corrosion protection compared to conventional painted metal substrates. Target customers include metal building manufacturers, roofing contractors, appliance producers, and architectural panel fabricators seeking long-term performance in demanding exterior environments.

What is Prime Color Prepainted Galvanized Steel Coil?

Prime color prepainted galvanized steel coil is a continuous coil-coated metal product manufactured through a precision roll-coating process that applies organic paint systems onto hot-dip galvanized steel substrates. The term "prime" indicates first-quality material meeting stringent coating adhesion, thickness uniformity, and surface finish standards per ASTM A755/A755M specifications, distinguishing it from secondary or off-grade coated steel products.

Prime Color Prepainted Galvanized Steel Coil Technical Specifications

Standard substrate thickness ranges from 0.18mm to 1.2mm with galvanized coating weights of Z80-Z275 (80-275 g/m² total both sides) per ASTM A653/A653M. PVDF topcoat thickness typically measures 25-30 micrometers with primer layers of 5-8 micrometers, achieving total dry film thickness of 30-38 micrometers. Color stability demonstrates ΔE <5 after 2,000 hours QUV-A exposure per ASTM G154, while pencil hardness reaches 2H minimum per ASTM D3363. Coating adhesion achieves 5B rating per ASTM D3359 crosshatch testing.

Why Choose Our Prime Color Prepainted Galvanized Steel Coil

Our manufacturing facility operates ISO 9001:2015 certified coil coating lines with advanced tension control systems maintaining ±2% thickness tolerance across full coil width. We utilize premium 70% PVDF resin formulations from Arkema or Solvay, ensuring 20-year warranty-grade performance in C3-C4 corrosivity environments per ISO 12944 classification. Mill-direct pricing eliminates distributor markups while maintaining complete mill test report traceability for every production coil.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Standard MOQ is 25 metric tons per color specification, equivalent to approximately 5-7 coils depending on thickness and width parameters. For high-volume construction projects exceeding 100 tons, we accommodate custom color matching per RAL, Pantone, or physical sample submission with lead times of 4-5 weeks for initial production runs.

Do you provide material test certificates?

Every shipment includes EN 10204 Type 3.1 mill certificates documenting substrate chemical composition per ASTM A653, zinc coating weight verification per ASTM A90 triple-spot testing, and coating thickness measurements per ASTM D7091 magnetic gauge readings. Additional certifications available include SGS third-party inspection reports and ASTM A755 compliance declarations upon request.

What is the typical delivery time?

Stock colors in standard dimensions (0.40-0.50mm × 1000-1250mm width) ship within 15-18 days ex-works from our coating facility. Custom color orders require 35-40 days including color approval sample production, batch coating, quality inspection, and export documentation preparation. Sea freight transit adds 18-25 days to major ports depending on destination routing.

Can you cut to custom sizes?

Our precision slitting lines accommodate width tolerances of ±3mm for widths ranging 600-1500mm, with recoiling capabilities for coil weights between 3-8 metric tons per customer specifications. Sheet cutting services provide length accuracy of ±5mm for panels up to 12 meters, with protective PE film application available to prevent transit damage during handling and installation phases.
