Why is Galvanized Steel more Expensive than PPGI Steel

Today we’ll address a common question from many customers: “Why is PPGI steel often cheaper than GI steel in the quotes I receive?” Is it normal for galvanized steel (GI) to cost more than pre-painted galvanized steel (PPGI), which has already undergone color coating? What are GI and PPGI? GI: Full name: Galvanized Steel. This

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,

Galvanized Hard Wire VS Galvanized Flexible Wire

Galvanized wire, a metal wire with excellent corrosion resistance, is one of the most basic yet indispensable materials in construction, agriculture, industrial manufacturing, and everyday hardware. It is widely used in construction binding, agricultural greenhouses, and industrial protection. Galvanized wire can be divided into galvanized hard wire and galvanized soft wire according to its material

Comparison of VCM Sheets for PET, PVC, and PET Film

What is VCM Sheet? VCM Sheet consists of three layers: substrate, adhesive, and film. The substrate provides structural strength, while the film offers scratch resistance, yellowing resistance, decorative appeal, and rust prevention. Substrate Layer: Cold-rolled steel sheet (SPCC) or hot-dip galvanized sheet (DX51D+Z). Bonding Layer: Water-based or solvent-based adhesive. Coating Layer: PET, PVC, or PETG
