Cold Rolled Sheets

Description

1. Product Overview
   Cold Rolled Sheets are high-precision flat steel products manufactured through a controlled cold rolling process that enhances surface finish, dimensional accuracy, and mechanical strength. They are widely used across automotive, construction, appliances, and precision engineering industries where tight tolerances and superior surface quality are critical. The key value proposition lies in their exceptional formability, strength-to-weight efficiency, and consistent performance under demanding fabrication conditions. Strategically, cold rolled sheets are a foundational input in modern industrial manufacturing, enabling downstream innovation, product durability, and cost-efficient mass production.
2. Key Specifications & Technical Characteristics

• Material Composition: Low-carbon steel (typically Fe with 0.05%–0.25% carbon), trace manganese, phosphorus, sulfur within controlled limits
• Steel Grades: Commercial Quality (CQ), Drawing Quality (DQ), Deep Drawing Quality (DDQ), Structural grades (as per ASTM, JIS, EN standards)
• Surface Finish: Bright, smooth, and scale-free surface due to pickling and cold reduction
• Thickness Range: Typically 0.3 mm – 3.0 mm (customizable depending on application)
• Width Range: 600 mm – 1500 mm (standard industrial supply range)
• Mechanical Properties: High tensile strength, improved yield strength, excellent elongation for forming
• Coil/SHEET Form: Available in coils, slit coils, and cut-to-length sheets
• Surface Treatment: Oiled or non-oiled options for corrosion protection
• Packaging Options: Standard export seaworthy packaging with anti-rust protection, steel strapping, and edge guards
• Shelf Life: Indefinite under proper dry storage conditions with corrosion prevention measures

3. Core Industrial Applications
   Cold Rolled Sheets are extensively used in automotive body panels, chassis components, and structural reinforcements where precision and surface quality are essential. In the construction sector, they serve in roofing systems, cladding, ducting, and structural frameworks requiring high strength and uniformity. Appliance manufacturing relies on these sheets for refrigerators, washing machines, air conditioners, and metal enclosures due to their aesthetic finish and formability. Compared to hot rolled alternatives, cold rolled sheets deliver superior dimensional accuracy, smoother surfaces, and enhanced mechanical performance, reducing post-processing costs and improving manufacturing efficiency.
