DX51D Galvanized sheet

DX51D (European Standard EN 10346) and SGCC (Japanese Standard JIS G3302) are two widely used international standards that specify commercial-grade hot-dip galvanized steel sheets. This product is manufactured by processing a low-carbon steel substrate through a continuous hot-dip galvanizing process, resulting in a steel product coated with a pure zinc layer. It is primarily intended for forming applications rather than structural load-bearing purposes.

DX51D / SGCC Galvanized Sheet Description

DX51D (European Standard EN 10346) and SGCC (Japanese Standard JIS G3302) are two widely used international standards that specify commercial-grade hot-dip galvanized steel sheets. This product is manufactured by processing a low-carbon steel substrate through a continuous hot-dip galvanizing process, resulting in a steel product coated with a pure zinc layer. It is primarily intended for forming applications rather than structural load-bearing purposes.

Key Features

Substrate: Low-carbon mild steel, offering excellent formability (deep drawing, bending).

Coating: A surface layer of pure zinc that provides sacrificial anode protection, preventing rusting of the substrate.

Primary Use: Suitable for formed components requiring subsequent painting or direct use.


Scope of Application

Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.

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. ‌
