Pre-coated galvanized color-coated coils use galvanized steel (GI) or galvanized steel (AZ) as the substrate. After surface degreasing and chemical conversion treatment, they are coated with an organic coating (such as polyester PE or fluorocarbon PVDF) and then baked and cured to form a colored coating. The core process includes substrate pretreatment, coating, and curing. The coating thickness is typically 15-25μm.

Bright Surface Steel Sheet Prepainted Galvanized Color Coated PPGI Steel Coil

The substrate is galvanized steel (GI) or galvanized steel (AZ). The zinc coating weight is 40-275g/m². The bright finish is achieved through skin-pass rolling. The reflectivity is ≥85%.

Coating options include polyester (PE) and fluorocarbon (PVDF). The front coating thickness is 15-25μm, and matte and gloss finishes are available.

GI Color Coated Steel Coil: A steel coil with an organic coating applied to a galvanized steel (GI) base, offering both the corrosion protection of the galvanized layer and the decorative appeal of a color coating.

PPGI Steel Roll: Prepainted galvanized steel coil. The base is galvanized steel, coated using a continuous roll coating process and then baked. It offers weather resistance and a variety of colors.

The AZ150 substrate features an aluminum-zinc alloy coating (55% aluminum content) with a zinc coating weight of 150g/m², conforming to ASTM A792M.

Pre-coating options include polyester (PE), silicone-modified polyester (SMP), or PVDF. Coating thicknesses range from 15-25μm on the front and 5-8μm on the back, supporting standard colors such as RAL 9019. Thickness ranges from 0.12-2.0mm, widths from 600-1250mm, roll weights from 1-6 tons, and inner diameters from 508/610mm.

Tensile strength ≥ 280MPa, yield strength ≥ 140MPa, elongation ≥ 14% (per GB/T 2518). Salt spray resistance reaches 1000 hours (red rust ≤ 5%), suitable for C3-C4 corrosion environments.

DX51D/DX52D/DX53D pre-coated galvanized steel coil (PPGI/PPGL) is a high-performance steel widely used in the construction, home appliance and automotive industries.

PPGI Steel Coil (pre-coated galvanized steel coil) is galvanized steel with a color coating.
