Shandong Churan Metal Materials Co., Ltd.

G550 Galvanized coil

Galvanized coil 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.

Product Details

G550 galvanized coil is a surface galvanized sheet with yield strength of  235MPa.

Galvanized coil, a thin steel sheet that is dipped into a molten zinc bath to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, in which rolls of steel sheet are continuously dipped into a bath of molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed coating of zinc and iron. This type of galvanized coil has good paint adhesion and weldability.

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. ‌
