Cold-rolled Steel Sheet: High Strength, Smooth Finish, and Diverse Specifications
Dinglian Co., supply Cold-rolled Steel Sheet, a steel product processed at room temperature after hot rolling to achieve tighter tolerances and improved surface finish. This results in higher strength and a smoother surface ideal for painting. Commonly used in automotive body panels, appliances, furniture, and construction materials. Classifications are based on factors like steel grade (carbon, alloy), surface finish (matte, bright), and temper (hardness), catering to diverse manufacturing needs.
Specifications
- Thickness Range: Common thicknesses typically span from 0.15 mm to 3.0 mm, catering to various structural and forming requirements.
- Width Range: Standard widths generally vary from 600 mm to 1500 mm, accommodating diverse fabrication processes and application needs.
- Length (for sheets): Standard sheet lengths often range from 2000 mm to 3000 mm, with custom lengths available based on specific orders.
- Coil Inner Diameter: Typical inner diameters for coils are usually 508 mm or 610 mm, fitting standard industrial handling equipment.
- Coil Outer Diameter: Outer coil diameters generally range from 1000 mm to 1800 mm, influenced by thickness and coil weight limitations.
- Steel Grade: Common grades include commercial quality (CQ), drawing quality (DQ), and structural grades (e.g., SAE 1008), each with distinct properties.
- Surface Finish: Typical finishes include matte, semi-matte, and bright, influencing the material's appearance and suitability for painting or coating.
- Edge Condition: Edges can be mill edge or slit edge, depending on the processing and intended use of the steel sheet.
- Temper/Hardness: Temper designations (e.g., full hard, half hard, quarter hard) indicate the steel's hardness and formability characteristics.
- Surface Treatment: Oiling or passivation is often applied to prevent rust and maintain surface quality during storage and transportation.
