Custom Cut White Black Sky Blue JIS CGCC PPGI Prepainted Color Steel Coils 0.12–1.20mm for Roofing and Building Panels

Custom Cut White Black Sky Blue JIS CGCC PPGI Prepainted Color Steel Coils 0.12–1.20mm for Roofing and Building Panels

1．Product Overview

Custom cut PPGI prepainted color steel coils are produced using hot dipped galvanized steel substrate combined with an organic paint coating system. The product is suitable for roofing sheets, wall cladding, appliance panels, and other visible fabricated sheet applications where both corrosion resistance and decorative appearance are required.

The material follows JIS G3312/94, GB/T 12754, and EN 10169 standards. The galvanized substrate and painted surface work together to improve durability, outdoor performance, and forming stability during downstream processing.

2．Technical Solution

The substrate uses galvanized steel with zinc coating range from 20–275g/m2. The painted side adopts 10–20 micron polyester plus 5 micron primer, while the reverse side uses 5–7 micron or 7–8 micron polyester plus 5 micron primer.

Available paint systems include polyester, SMP, and PVDF. Polyester is suitable for standard building applications, SMP improves weather resistance, and PVDF provides stronger UV resistance and longer outdoor durability.

The product is suitable for commercial quality processing and lock forming quality applications, supporting common roll forming and roofing panel production.

4．Application

This material is suitable for roofing sheets and wall cladding in workshops, warehouses, airports, commercial buildings, and industrial facilities.

It is also used for household appliance panels, container sheets, electrical equipment housings, and visible decorative steel parts requiring coated surface protection and stable forming performance.

The product supports downstream roll forming, cut-to-length production, and slitting processing.

5．Processing

• The coil can be supplied for cut-to-length sheet production according to customer size requirements.
• It can be slit into narrower widths for roofing sheet and wall panel processing.
• Protective film can be applied on the top side for visible surface protection during transportation and fabrication.
• The product is suitable for roll forming, bending, profiling, and common sheet fabrication operations.

6．Advantages

• The product uses galvanized steel substrate with zinc coating range from 20–275g/m2 for corrosion protection.
• Thickness range of 0.12–1.20mm covers mainstream roofing sheet and panel fabrication requirements.
• Width range of 700–1250mm matches standard roll forming and panel production lines.
• Polyester, SMP, and PVDF paint systems are available for different outdoor exposure environments.
• The product supports custom RAL color production and customized cutting service.
• Commercial quality and LFQ grade support stable forming performance during downstream processing.

7．How to Choose

• Choose polyester coating for standard roofing and indoor building applications.
• Choose SMP coating when better weather resistance and coating hardness are required.
• Choose PVDF coating for projects requiring longer outdoor service life and stronger UV resistance.
• Choose higher zinc coating levels for humid or coastal environments.
• Choose thickness according to panel rigidity and forming requirements.
• Confirm width and coil weight according to downstream roll-forming equipment capacity.
