PPGI stands for Pre-painted Galvanized Steel Sheet, commonly referred to in the industry as color-coated steel sheet or color-coated steel plate.

1. Common Substrate Types

Substrate TypeFeaturesApplication
Hot-dip Galvanized (GI)Good corrosion resistance, cost-effectiveGeneral construction, interior decoration, home appliance shells
Galvalume (GL/AZ)Higher corrosion resistance, better heat resistanceBuilding roofs/walls, outdoor construction, high weather resistance applications

2. Coating Types

Coating TypeFeaturesTypical Applications
Polyester (PE)General-purpose, bright color, good formabilityGeneral buildings, workshops, warehouses
Silicone-Modified Polyester (SMP)Better weatherability and chalking resistance than PEOutdoor buildings, roofs, exterior walls
High Durability Polyester (HDP)Excellent gloss and color retentionCoastal areas, high UV environments
Polyvinylidene Fluoride (PVDF)Top-level weather resistance, UV & chemical corrosion resistanceLandmark buildings, airports, convention centers
Epoxy (EP)Good chemical resistance & adhesionInner panels of home appliances, parts with high anti-corrosion requirements

3. Common PPGI Grades (By Standard)

Standard SystemCommon GradesDescription
China GB / Europe ENDX51D+Z / DX51D+ZMMost common commercial grade, for general bending, forming and roll forming
China GB / Europe ENDX52D+Z / DX53D+ZDrawing and deep-drawing grades for complex forming parts
China GB / Europe ENS250GD+Z / S350GD+ZStructural grades with higher yield strength for load-bearing components
Japan JISJIS G3312 CGCCMost common color-coated steel grade for general construction and appliances
Japan JISCGC340 / CGC440 / CGC570Numbers indicate tensile strength (MPa); CGC570 corresponds to high-strength material such as G550
USA ASTMASTM A755M CS-BCommercial grade, widely used in building envelope systems
USA ASTMSS255 / SS275 / SS550Structural grades; numbers indicate minimum yield strength (MPa)
