1. Construction and Infrastructure Sector
Basic applications: beams, columns, and floor slabs for steel structure workshops, load-bearing slabs for bridges, supporting elements for curtain walls of high-rise buildings, and shield segments for metro and tunnel tunnels;
Common types: Hot-rolled steel plates of grades Q235 and Q355 (for structural applications), weathering steel plates of grade Q355NH (for bridges and outdoor landscaping), and stainless steel plates of grade 304 (for decorative curtain walls).
2. Automotive and Transportation Sector
Primary applications: Body structures (cold-rolled steel sheets, such as DC01), doors/front cover (high-strength cold-rolled steel sheets), chassis components (alloy steel sheets, such as 40Cr), truck cabins (wear-resistant steel sheets, such as NM360);
Requirements: Lightweight (using partial use of high-strength thin steel plates), impact-resistant (ensuring collision safety), easy to process (adaptable to complex shapes).
3. Machinery and Equipment Manufacturing Sector
Core applications: machine bed frames (constructed from steel and cast iron plates), construction machinery arms (Q355 alloy steel plates), mining equipment liners (NM450 wear-resistant steel plates), pressure vessels (low-temperature steel plates 16MnDR, stainless steel plates 316L);
Requirements: High strength, high corrosion resistance, and resistance to corrosion by specific media (such as acid and alkali resistance for chemical equipment).
4. Food and Chemical Industry
Basic applications: food storage tanks, transfer pipelines (304 stainless steel plates), chemical reaction vessels, acid and alkali storage tanks (316L stainless steel plates), fermentation equipment (304L stainless steel plates);
Requirements: Non-toxic (food-grade), highly corrosion-resistant (to prevent contamination of the medium and damage to equipment), and easy to clean.
5. Construction and Decoration Fields
Primary applications: Home appliance casings (cold-rolled steel sheets, such as SPCC), security doors (cold-rolled sheets made from hot-rolled steel grade Q235), furniture frames (cold-rolled steel sheets), outdoor landscaping (weather-resistant steel sheets, such as Q295NH);
The appearance must be aesthetically pleasing, the dimensions must be precise, and some components must be rust-resistant (such as stainless steel panels used for exterior decoration).
