Китайский поставщик и производитель холоднокатаной стальной пластины

Sanhe Steel is a professional cold-rolled steel plate manufacturer in China, deeply engaged in the production of cold-rolled steel plates for many years. With advanced equipment and strict quality control, it creates cold-rolled steel plate products with flat surface, precise size, and stable performance, suitable for precision machining and structural material needs of various industries, and provides a global one-stop cold-rolled steel solution.

Cold rolled steel plates are made from high-quality hot-rolled steel coils and processed through multiple passes of rolling, degreasing, annealing, and leveling at room temperature. They do not require high temperature heating, have no iron oxide scale, have a smooth surface, small dimensional tolerances, and uniform thickness.

Sanhe Steel cold-rolled steel plates use high-quality substrates and advanced annealing processes, with excellent stamping, bending, and welding properties. They can provide customized processing such as flattening, slitting, and cutting, without the need for customer secondary processing, improving production efficiency.

Compared to traditional products, Sanhe Steel cold-rolled steel plates have advantages in corrosion resistance, surface smoothness, and dimensional accuracy. After strict physical and chemical testing, they meet national and industry standards and are widely used in industrial manufacturing, gaining customer recognition.

Core classification of cold-rolled steel plates (subdivided by four major dimensions)

Classified by material grade (suitable for different processing strengths)

The material grade determines the processing performance and applicable scenarios of cold-rolled steel plates. Sanhe Steel can produce various grades of core products as needed:

SPCC ordinary cold-rolled sheet: basic version, uniform material, moderate toughness, suitable for metal stamping, sheet metal parts, office furniture, etc., with high cost-effectiveness and large usage.

SPCD stamping grade cold-rolled sheet: With good stamping formability, it can withstand medium strength stamping and is suitable for complex sheet metal parts, home appliance liners, small automotive parts, etc.

SPCE deep drawn cold-rolled sheet: high-end version with high elongation, capable of deep drawing, suitable for high-end automotive parts, precision instruments, high-end home appliance shells, etc.

National standard cold-rolled sheet (Q195, Q235): Complies with GB/T 708-2016 standard, with high strength and stable toughness, suitable for structural load-bearing components, mechanical supports, etc.

Customized grade cold-rolled sheet: Develop special material properties as needed, suitable for high-end equipment, aerospace and other special fields.

Classified by surface treatment (meeting rust prevention and appearance requirements)

Sanhe Steel offers a variety of surface treatment processes to adapt to different usage environments and appearance requirements:

Bright cold-rolled sheet: The surface is as smooth as a mirror and does not require spraying. It is suitable for home appliance casings, decorative panels, precision instrument casings, etc.

Frosted cold-rolled sheet: With a frosted texture, it is anti slip and wear-resistant, suitable for furniture countertops, mechanical equipment casings, elevator panels, etc.

Phosphating rust proof plate: Phosphating film rust proof, improves spray adhesion, suitable for automotive parts, electrical cabinets, outdoor hardware, etc.

Oil coated protective plate: Apply anti rust oil to prevent rust during storage and transportation, suitable for products that are stored for a long time and transported over long distances.

Coated cold-rolled sheet: covered with protective film to prevent scratches and stains, suitable for high-end home appliances, decorative panels, etc.

Classified by thickness specifications (suitable for different size requirements)

Sanhe Steel cold-rolled steel plates come in a complete range of specifications and support customization of special thicknesses. Specific classifications:

Thin cold-rolled sheet (0.2mm-0.5mm): lightweight, good formability, suitable for precision hardware, electronic component casings, etc.

Conventional cold-rolled sheet (0.6mm-1.5mm): widely used, balancing toughness and strength, suitable for household appliances, automotive interiors, office furniture, etc.

Medium thick cold-rolled sheet (1.6mm-3.0mm): High strength, suitable for mechanical supports, structural components, large sheet metal parts, etc.

Special thickness customization (over 3.0mm): Suitable for special needs such as heavy machinery, building structures, and large equipment casings.

All thickness cold-rolled steel plates can be customized with widths (conventional 1000mm, 1250mm, 1500mm), suitable for production lines, reducing waste and lowering costs.

Classify by application purpose (accurately match industry)

Sanhe Steel divides cold-rolled steel plates by purpose for customers to quickly select:
