Cold rolled galvanized steel is a ferrous metal material produced through cold rolling and hot-dip galvanizing. It combines the strength and formability of cold-rolled steel with the corrosion resistance of the zinc coating. Commonly sold in coil, sheet, and strip forms, it serves as a fundamental material widely used in industrial and construction applications.

Specifications
| Dimension | Common Range |
| Base Material Thickness | 0.15mm – 6.0mm |
| Width | 600mm – 1250mm |
| Length | Coils or Cut-to-Size Sheets |
| Zinc Coating Weight | Z30 – Z350 |
| Surface Treatment | Regular Zinc Flower, Small Zinc Flower, No Zinc Flower, Phosphating, Oiled |
Grade
| Standard | Grade Example | Performance and Applications |
| European Standard (EN) | DX51D | Most commonly used. Low carbon steel base, excellent formability, used for deep drawing, bending, etc. |
| DX52D, DX53D | Better anti-aging stability, used for higher forming processing requirements. | |
| S220GD, S350GD | Structural grade. Used for components requiring higher strength, such as beams, columns, and load-bearing structures. | |
| Chinese Standard (GB/T) | DC51D | Corresponds to EN’s DX51D, cold-rolled low carbon steel sheet for stamping. |
| DC52D, DC53D | Corresponds to DX52D, DX53D. | |
| S250GD, S350GD | Corresponds to EN’s structural grades. | |
| American Standard (ASTM) | A653 | Common grades include CS Type B (commercial grade), FS Type B (forming grade), SS Grade 33 (structural grade). |
Property
| Property | Description |
| Corrosion Resistance | Core performance. Directly determined by the zinc coating weight. In standard atmospheric conditions, Z275 lasts far longer than Z90. The “sacrificial anode” protection of zinc also protects areas like cuts and scratches. |
| Formability | Determined by the base material performance. Most cold-rolled galvanized steel can undergo cutting, stamping, bending, and rolling forming (roof tile pressing), among other processes. |
| Coating Property | Surface can serve as a substrate for color-coated sheets (PPGI/PPGL), with good paint adhesion. |
| Weldability | Can undergo welding operations like spot welding. |
| Strength | Structural-grade materials have high yield strength and tensile strength, capable of bearing larger loads. |

Cold Rolled Galvanized Steel Process
Cold rolled galvanized steel utilizes high-quality cold-rolled steel coil as the substrate, coated with a dense zinc layer. It offers excellent strength, formability, corrosion resistance, and decorative properties, making it widely used in construction, interior decoration, industrial production, and other fields.
Processing
- Process: Cold-rolled steel is immersed in molten zinc (approximately 450-460°C), causing a metallurgical reaction between zinc and the steel surface to form a zinc-iron alloy layer.
- Characteristics: Thick coating, strong adhesion, excellent corrosion resistance.
- Process: Zinc ions are deposited onto the cold-rolled steel surface through electrolysis, forming a uniform zinc layer.
- Characteristics: Thin coating, smooth surface, excellent workability.
Characteristics
- Corrosion Resistance: In humid or salt-fog environments, the zinc layer corrodes preferentially, extending the service life of the cold-rolled steel.
- Processability: Retains the strength, toughness, and machinability of cold-rolled steel.
- Appearance & Aesthetics: Features a silver-gray metallic finish that is both visually appealing and durable, with further enhancement possible through painting.
- Environmental Considerations:
- Cost-Effectiveness: Offers a highly economical rust-proof solution compared to other corrosion-resistant metals like stainless steel.
- Environmentally Friendly: The galvanizing process meets environmental standards. Zinc is recyclable, and the zinc coating prevents heavy metal pollution caused by steel corrosion.
Applications
- Construction Industry: Roofing, walls, partitions, door/window frames, steel bridges, ventilation ducts, etc.
- Automotive Industry: Manufacturing vehicle bodies, chassis, exhaust pipes, and other components.
- Home Appliance Manufacturing: Outer casings for refrigerators, washing machines, air conditioners, etc.
- Agriculture & Infrastructure: Construction of grain silos, water troughs, guardrails, traffic signs, etc.
- Energy Sector: Used in solar panel mounts, wind turbine towers, etc.
- Advanced Processing: Galvanized sandwich panels, galvanized doors,GI purlins, pre-painted galvanized steel coil (PPGI), etc.
