PPGI Color Coated Steel Sheet for Home Appliance and Electrical Housing

Product Description

PPGI / Color Coated Steel Sheet

Material

Carbon Steel Base: Q195, Q235, SGCC, DX51D, DX52D, DX53D etc.

Selection Recommendations

Corrosion resistance requirements: Zinc-aluminum coated substrate (GL/PPGL) is recommended for coastal and high-humidity areas.

Processing Requirements

Mild steel base (Q195-Q235) features good ductility, easy bending, stamping and cutting for roofing & wall panels.

Cost Control

Ordinary galvanized substrate + color coating is cost-effective, ideal for bulk procurement of construction projects.

Process of Color Coated Steel Sheet (PPGI/PPGL)

The production of color coated steel sheet mainly consists of two major stages: base coil manufacturing (galvanized/aluminum-zinc coated coil) followed by color coating treatment. The specific process is structured as follows:

1. Base Coil Manufacturing

  • (1) Hot-dip galvanized steel coil (GI) Raw materials: hot-rolled or cold-rolled steel coils (Q195-Q235, DX51D, SGCC, etc.)
    Process flow: Steel strip uncoiling → leveling → continuous hot-dip galvanizing → cooling → passivation → oiling → inspection
    Common types: regular spangle, minimized spangle, zero spangle galvanized coil.
  • (2) Aluminum-zinc coated steel coil (GL) Raw material: cold-rolled carbon steel strip
    Process flow: Strip cleaning → high-temperature zinc-aluminum alloy plating → cooling → passivation → inspection
    Plating characteristics: stronger corrosion resistance than ordinary galvanized coil, ideal for coastal and high-humidity environments.

2. Color Coating Process

The main types of color coating are single-coat single-bake and double-coat double-bake, of which double-coat double-bake is widely used for outdoor construction materials:

  • (1) Double-coat Double-bake Color Coating Process: Alkali degreasing → surface cleaning → chemical conversion treatment → drying → primer coating → baking → topcoat coating → baking → cooling → film thickness inspection
    Coating characteristics: uniform paint film, strong weather resistance, anti-ultraviolet, long service life, suitable for roofing, wall panels and outdoor engineering use.
  • (2) Single-coat Single-bake Color Coating Process flow: Surface cleaning → passivation treatment → single layer topcoat coating → baking → cooling → inspection
    Coating characteristics: thin paint layer, cost-effective, suitable for indoor decoration, temporary buildings and general industrial applications.
