Product Overview

RAL Custom Colors Prepainted Steel Sheet (PPGI / PPGL) refers to color coated steel sheet produced strictly according to RAL classic color system, widely recognized by architects, contractors and metal building buyers globally. Besides standard RAL codes, we also provide custom color matching service when clients provide physical color chips or reference samples.

The substrate options are hot-dip galvanized PPGI and galvalume PPGL. Buyers can pair any RAL / custom color with PE, SMP, HDP or PVDF coating grade, to combine target color appearance and required weather resistance. Popular RAL colors include RAL9002, RAL9003, RAL7016, RAL3005, RAL5010, RAL6005. Matte, glossy, wrinkle, wood grain and marble textures are available upon request.

Our factory controls color difference strictly during coil coating process. Pre-production color swatches and test panels are supplied for client approval to avoid color deviation on bulk shipment. These RAL custom color sheets are widely used for building roofing, wall cladding, prefabricated housing, curtain wall, garage doors, container housing and decorative metal panels. All sheets adopt export seaworthy packaging, with waterproof wrapping and steel protectors to prevent scratch and color damage during long sea transit. We support different thickness, width, zinc layer and paint thickness customization for international construction projects.

Important Notes for Color Ordering

Confirm the color standard**: Please specify RAL number, Pantone number or physical sample.

Check gloss requirement**: The same color will look different under high gloss, semi-gloss or matte finish.

Coating system matters**: PE, SMP, HDP and PVDF may affect final color appearance and weather resistance.

Color difference exists**: There may be slight color variation between different batches and between screen display and actual steel sheet.

Pre-production confirmation**: We recommend confirming a physical color swatch or trial sample before mass production.

Project specific colors**: For architectural projects, color grouping and color separation requirements should be confirmed in advance.

FAQs

Can I confirm RAL color via screen picture only before order?

Screen display will have color deviation. We suggest confirming by physical color swatch or pre-production panel to avoid difference after mass production.

What is the MOQ for non-standard custom matched color PPGI sheet?

Standard RAL colors MOQ is 5 tons. Custom matched colors require minimum 10 tons per color due to paint mixing setup.

How long is lead time for custom RAL color prepainted steel sheet?

Popular standard RAL colors: 7–15 working days. New custom color matching needs extra time for paint formulation, total lead time 15–25 working days.

Can I combine multiple different RAL colors into one container shipment?

Yes, multiple RAL colors can be mixed in one container, each color meets its own MOQ requirement.

What causes color difference between batches for RAL PPGI sheet?

Raw paint batch variation, curing temperature and light viewing angle may cause minor difference. Our factory controls ΔE ≤2 to guarantee consistency for construction projects.

Is RAL color coating scratch resistant during roll forming?

The coating has good flexibility for normal bending and corrugation. But sharp scratches during transportation or processing will damage the paint layer, we suggest protective film if you have strict surface requirements.
