PPGI ASTM A653 Prepainted Color Steel Coils 700–1250mm Width for Roofing and Construction Panels

1．Product Overview

PPGI ASTM A653 prepainted color steel coils are manufactured using hot dipped galvanized steel substrate combined with continuous organic coating technology. The product is suitable for roofing sheets, wall cladding, household appliance panels, and visible construction sheet applications requiring decorative appearance together with corrosion resistance.

The product complies with ASTM A653, JIS G3312/94, GB/T 12754, and EN 10169 standards. The galvanized substrate and painted coating structure provide stable outdoor durability and good downstream forming performance for roofing and panel fabrication.

2．Technical Solution

The product uses galvanized steel substrate with zinc coating range from 20–275g/m2. The exposed surface 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 coating is suitable for standard construction projects, SMP improves weather resistance and coating hardness, while PVDF provides stronger UV resistance and longer outdoor service life.

The product supports commercial quality processing and lock forming quality applications for roll forming and profile sheet production.

3．Specifications

4．Application

The product is widely used for roofing sheets, wall panels, steel structure buildings, warehouses, airports, workshops, and commercial construction projects.

It is also suitable for household appliance panels, container plates, transportation equipment panels, and electrical equipment housings requiring coated decorative steel surfaces.

The product supports downstream roll forming, bending, slitting, and cut-to-length fabrication.

5．Processing

• The coil can be supplied for cut-to-length sheet production according to customer size requirements.
• It supports slitting service for narrower coil widths used in roofing and wall panel production.
• Protective film can be applied to the top side for visible surface protection during transportation and forming operations.
• The material is suitable for roll forming, bending, profiling, and standard sheet fabrication processes.

6．Advantages

• The product uses galvanized steel substrate with zinc coating range from 20–275g/m2 for improved corrosion protection.
• Thickness range of 0.12–1.20mm supports mainstream roofing sheet and panel fabrication requirements.
• Width range of 700–1250mm matches standard roll-forming and construction panel production lines.
• Polyester, SMP, and PVDF coating systems are available for different outdoor exposure environments.
• The product supports customized RAL colors and downstream cutting or slitting services.
• Commercial quality and LFQ processing performance improve forming stability during fabrication.

7．How to Choose

• Choose polyester coating for general roofing and indoor construction applications.
• Choose SMP coating for projects requiring better weather resistance and coating hardness.
• Choose PVDF coating for long-term outdoor exposure and high UV environments.
• Choose higher zinc coating levels for coastal or humid environments requiring stronger corrosion resistance.
• Confirm thickness according to structural rigidity and roll-forming requirements.
• Select coil width according to downstream roofing sheet or wall panel production equipment.
