Our GB/T 12754 Prepainted Galvanized Steel Coils are produced in strict accordance with the Chinese National Standard for “Prepainted steel sheet and strip for building uses.” As a direct manufacturer, Bomis Steel leverages advanced continuous color coating Anti Fingerprint Stainless Steel lines to deliver PPGI that balances structural strength with superior aesthetic finishes, making it the premier choice for global infrastructure and industrial warehousing.
The GB/T 12754 standard is renowned for its rigorous classification of coating types and performance metrics. Our production process focuses on the three critical elements defined by this standard:
Substrate Reliability: We utilize high-quality hot-dip galvanized steel (consistent with GB/T 2518) as the base metal, ensuring a robust zinc iron alloy layer that prevents lateral corrosion.
Coating Designations: We offer specialized coatings including PE (Polyester), SMP (Silicone Modified Polyester), HDP (High-Durability Polyester), and PVDF (Polyvinylidene Fluoride), each tailored to specific atmospheric corrosivity categories.
Grade Variety: From commercial grades (TDC51D+Z) to structural grades (TS280GD+Z), we provide the exact mechanical properties required for diverse forming needs.
Excellent T-bend performance ($leq 3T$) ensures no paint cracking during the manufacturing of roofing tiles or sandwich panels.Surface Versatility: Available in regular gloss, high gloss, matt, or embossed textures to meet varied architectural aesthetics.Direct Manufacturer Pricing: By eliminating middleman costs, we provide “China Manufacturer Direct Prices” without compromising on GB/T standard compliance.

The prepainted galvanized steel coil, compliant with the GB/T 12754 standard, is suitable for mainstream applications in South America and Southeast Asia, primarily in the construction, industrial, and consumer sectors. These applications are highly compatible with the local climate and infrastructure needs.
Construction Sector (Highest Proportion)
Building Facades/Roofs: In the tropical/subtropical climates of South America and Southeast Asia, characterized by high temperatures, high humidity, strong UV radiation, and heavy salt spray in coastal areas, products conforming to GB/T 12754 with high-weather-resistant coatings (HDP/PVDF) can resist environmental corrosion. Customizable colors can also match local architectural styles, such as the facades of resort hotels in Southeast Asia and the roofs of residential buildings in South America.
Interior Decoration: Partition walls, ceilings, and decorative panels in shopping malls, office buildings, and residences. The standard requirements for dimensional accuracy and coating adhesion ensure aesthetics and durability after installation. Products with ordinary polyester coatings can meet these needs.
Temporary Buildings/Modular Buildings: Temporary dormitories at local infrastructure project construction sites, temporary housing after disasters. These scenarios require rapid construction. Standard-compliant products have good processing performance, and their corrosion resistance ensures the service life of temporary buildings.
1.what is GB/T 12754 Galvanized Coil
GB/T 12754 is a Chinese standard specifying requirements for steel sheets and strips. It covers coils or sheets made from galvanized steel (GI, such as DX51D+Z) as the base material, which are then coated with an organic coating (such as polyester PE, epoxy EP) after surface treatment and curing. These products possess both decorative and corrosion-resistant properties. Applications include building exterior panels, roofing panels, partition panels, appliance casings, and advertising signs.
