Pre-Painted Metal Coatings: HDP vs SMP

Color-coated metal (PPGI, PPGL, PPAL, Color-coated stainless steel) commonly uses High Durability Polyester (HDP) and Silicone Modified Polyester (SMP) coatings as the most mainstream options between standard polyester and top-tier PVDF. Both share similar costs and equivalent corrosion resistance lifespans, both belonging to mid-to-high-end organic coatings for outdoor use. However, HDP-coated sheets are gradually replacing

GI Sheet Gauge to mm

The thickness of galvanized steel sheet refers to the thickness of the base metal (substrate), excluding the thickness of the surface zinc layer. There are several ways to express this thickness; some regions commonly use “gauge” (abbreviated as GA), while others use metric units (mm). Both methods are widely used in the field of metal

Classification of Galvanized Structural Steel for Construction

Galvanized structural steel is ubiquitous in construction projects and industrial facilities. Leveraging its high strength for load-bearing and long-lasting corrosion resistance, it serves as the skeletal material providing structural support and decorative functions across various building components. Based on its role in construction, it can be categorized into four types: primary structural steel, secondary structural

Applications of Galvanised Steel Tube

Galvanized steel tube leverage dual advantages in corrosion resistance and structural integrity. Their distinct cross-sectional forms—round pipes and square/rectangular pipes—precisely meet diverse demands ranging from fluid transportation to framework support. Round pipes, with their uniform stress distribution and smooth inner walls, specialize in conveying water, gas, oil, and other fluids. Square and rectangular pipes, meanwhile,
