Zinc 60g 275g Gi Pre Painted Steel Sheet CRC PPGI Galvanized Steel Coils For Roofing Materials

Zinc 60g 275g Gi Pre Painted Steel Sheet CRC PPGI Galvanized Steel Coils For Roofing Materials

1. Product Overview

PPGI galvanized steel coil is used where a zinc-coated steel substrate and a finished color surface are required in one material. It is suitable for roofing materials, wall cladding, façade panels, and general fabricated sheet parts where corrosion resistance, appearance, and forming compatibility need to be considered together.

This product range covers 0.2–1.0mm thickness and 700–1250mm width in the main page configuration. It is designed for roofing and construction use, while also remaining suitable for downstream sheet conversion and profile forming.

2. Technical Solution

The product uses a galvanized steel base combined with an organic paint system. In practical use, final service performance depends on the zinc coating level, the paint film build, the forming route, and the installation environment.

The page lists a zinc coating range of 60–275g/m2 for galvanized roofing material use. The top side uses a primer plus finish coat structure, and the back side uses a lighter protective back coat. This combination supports sheet forming and exterior use while keeping the visible surface suitable for direct installation.

For roofing materials, actual durability is also affected by cut edge exposure, overlap design, drainage detail, and the local atmosphere at the installation site.

3. Specifications

4. Application

This material is suitable for roofing sheets, roof panels, wall cladding, and façade panels in residential, commercial, and light industrial buildings.

It can also be used for home appliance panels, decorative sheet parts, automotive related components, and general construction sheet fabrication where a finished painted surface is preferred over post-paint processing.

For roofing applications, it is more suitable when the zinc coating level, sheet thickness, and profile design are selected according to the actual service environment.

5. Processing

• The coil can be supplied for cut-to-length processing, roll forming, slitting, plain sheet production, and corrugated roofing sheet production.
• It is suitable for bending, profiling, and general sheet metal fabrication. For visible surface parts, careful handling during storage, transport, and installation is important to reduce scratching on the painted face.
• When the product is used for deeper roofing profiles or tighter bends, thickness, hardness, and paint structure should be checked together to keep forming stability and surface quality in balance.

6. Advantages

• The 0.2–1.0mm range covers common roofing and cladding sheet processing.
• The zinc coating range of 60–275g/m2 allows the product to be matched to different corrosion environments instead of using one fixed coating level for all projects.
• The painted surface provides direct installation appearance and helps reduce downstream painting work.
• The 700–1250mm width range matches mainstream roofing and cladding processing lines.
• Multiple substrate and grade routes listed on the page make the product adaptable to different fabrication and project requirements.

7. How to Choose

• Choose a lower zinc coating level for lighter service conditions and a higher zinc coating level within the listed 60–275g/m2 range when the environment is more demanding.
• Choose thinner gauges when easier forming and lower panel weight are important. Choose thicker gauges when more rigidity is needed.
• Choose width according to the final effective coverage, roll forming line, and panel layout.
• Check the top and back coating structure together when the project has specific requirements for visible surface quality, roof exposure, or fabrication severity.
