Customizable RAL Color Coated Prepainted Steel Coil for Diverse Fabrication

Overview

The Customizable RAL Color Coated Prepainted Steel Coil is a premium metallurgical product designed to meet the aesthetic and functional demands of modern manufacturing and construction. Built on a galvanized (PPGI) or galvalume (PPGL) steel substrate, this coil features a pre-applied polymer coating in any shade from the RAL color system, offering precise color matching for global projects. The production process integrates advanced roll-coating technology, ensuring uniform color distribution, excellent adhesion, and resistance to environmental degradation.

Available in thicknesses ranging from 0.15mm to 2.0mm and widths up to 1250mm, the coil balances formability with corrosion resistance. The RAL color customization (over 200 standard shades plus bespoke options) makes it ideal for applications requiring consistent branding, architectural harmony, or decorative finishes. Whether used in raw form for industrial components or as a pre-finished material for visible surfaces, this coil delivers reliability and visual appeal.

Features

Precision Color Matching: Utilizes the internationally recognized RAL color system to achieve exact shade replication, critical for brand consistency in commercial projects or architectural coherence in multi-building complexes.

Superior Coating Technology: Combines a zinc-rich primer and polyester/PVDF topcoat to resist UV fading, chalking, and chemical corrosion, with salt spray test results exceeding 1,000 hours for coastal applications.

Exceptional Formability: Maintains ductility after painting, enabling complex stamping, roll-forming, and bending without coating cracking—ideal for producing intricate shapes in automotive or appliance manufacturing.

Efficient Production Ready: Supplied in large coils for continuous processing, reducing downtime in roll-forming lines and minimizing material waste through custom slitting and cutting services.

Environmental Compliance: Meets EU RoHS and REACH standards, with lead-free, low-VOC coatings that contribute to sustainable building certifications (LEED, BREEAM) when used in green projects.

Application

Building Cladding & Roofing: Creates visually striking facades and roofs for commercial buildings, hotels, and residential complexes, with color options ranging from bold primaries to subtle metallics.

Home Appliances: Forms panels for refrigerators, washing machines, and air conditioners, where consistent color and surface smoothness enhance product aesthetics and durability.

Automotive Components: Used for truck bodies, trailer panels, and interior trim, offering resistance to road salt and UV exposure while enabling OEM-specific color customization.

Signage & Furniture: Fabricates durable outdoor signs, store fixtures, and metal furniture, with scratch-resistant coatings that preserve color vibrancy in high-traffic environments.

FAQ

Q: How many RAL colors are available?

A: We offer all 213 standard RAL Classic and RAL Design colors, plus custom color matching for non-standard shades upon request.

Q: Can the coil be painted after fabrication?

A: While pre-painted for convenience, the surface is compatible with additional topcoats if specific performance (e.g., anti-graffiti) is required, though priming may be necessary.

Q: What is the minimum order quantity for custom colors?

A: Standard RAL colors have no MOQ, while bespoke shades require 50 tons to cover pigment calibration costs.

Q: How does temperature affect the coating?

A: The coating withstands -50°C to 120°C continuously; for higher temperatures (e.g., industrial chimneys), a heat-resistant topcoat upgrade is available.
