SGCC PPGI

SGCC is a grade of galvanized steel defined in the Japanese JIS G3302 standard. It offers good formability, corrosion resistance, and surface quality. When coated with a layer of paint to produce pre-painted galvanized steel coils, it further enhances the metal’s corrosion resistance and improves its decorative appeal.

SGCC PPGI steel can be supplied as full coils or further processed into color-coated steel sheets, slit coils, and cut-to-length sheets. They are suitable for applications in construction, home appliances, doors and windows, equipment enclosures, and various metal fabrication projects.

Why SGCC Is Suitable as a Substrate for PPGI

SGCC is one of several commonly used substrates for PPGI and has a well-established track record in PPGI production. The specific reasons are as follows:

Good formability: SGCC is suitable for various processing methods, including roll forming, bending, cutting, punching, and profiling. These processing capabilities are crucial for manufacturing complex shapes such as corrugated roofing sheets and home appliance casings.
Good Corrosion Resistance: SGCC is a hot-dip galvanized material; the zinc coating on its surface protects the steel, providing basic corrosion resistance for PPGI sheets used in outdoor construction.
Strong Adhesion: The hot-dip galvanized coating on the surface of SGCC has excellent affinity with paint coatings, resulting in superior paint adhesion.

SGCC PPGI Steel Applications

Construction Industry: Used for roofs and walls in buildings (factories, stadiums, convention centers, etc.) and building facades.
Home Appliance Manufacturing: Side and back panels for refrigerators; housings for outdoor and indoor units of air conditioners; washing machine enclosures; and water dispenser housings.
Doors and Interior Finishing Products: Used in the manufacture of metal doors, garage doors, interior trim panels, ceilings, and interior partition panels.

SGCC PPGI Coil Processing Options

Slitting: Slitting master coils into smaller coils of various widths according to customer requirements. The resulting PPGI steel strips are suitable for purchase by door and window manufacturers, profile manufacturers, and metal fabricators.
Cut to Length: Processing steel coils into PPGI steel sheets of fixed lengths. Suitable for metal panels, home appliance panels, and roofing panels.
Customized Coil Weight: Some customers in certain countries have limited capacity to handle certain coil weights, so customized coil weights are required.

What Needs to be Confirmed When Purchasing SGCC PPGI?

When purchasing PPGI, it is essential to consider not only the price per metric ton but also the following factors:

Base metal + Zinc coating + Paint system + Paint thickness + Color + Coil size + Coil weight + Packaging + Delivery

For example, consider two 0.45 mm SGCC PPGI steel coils: if one product uses a thinner zinc coating and a standard PE coating, while the other uses a thicker zinc coating and an HDP coating, their costs and final performance characteristics will differ.

Therefore, if you need pricing information, please confirm these parameters. If you are unsure, feel free to contact us—we will recommend the product best suited to your specific application and environment.
