Technical QA/QC Verification

Yield Strength & Mechanical Audit: G550 structural coils undergo rigorous tensile testing to ensure the 550MPa yield threshold is met, preventing structural deformation in roofing applications.

Certification & Security: We provide EN 10204 3.1 MTCs with every shipment. To protect global buyers, SXY Steel Group supports 100% Irrevocable Letters of Credit (L/C) at sight to ensure zero capital risk.

Internal Protection & Ocean Logistics

Transit Preservation: Coils are wrapped in anti-corrosion vapor-barrier paper and encased in galvanized steel shells to prevent moisture ingress and white rust.

Port Efficiency: We negotiate up to 21 days of free container demurrage on your Bill of Lading, saving you from destination administrative penalties.

Galvanized sheet G550 belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.

PPGI is galvanized color plate, PPGL is galvanized color plate, both are color plates, the substrates are different, one is galvanized structure, the other is galvanized structure, the substrate is different, which determines the difference in performance.

Advantages: It not only has the mechanical strength and easy forming properties of steel plates, but also has good decorative properties and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. Application: Widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.

Application Areas

Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments. ‌
