Matte Finish Cold Rolled Steel Coil

Product Specifications and Selection

The following grades, standards and configuration details provide a basis for discussing cold rolled carbon steel coil requirements. Final specifications are matched to the selected grade and confirmed for each order.

Select the Grade for Your Forming Process

The right grade depends on the component shape and the degree of deformation required during production.

• SPCC: A general-purpose option for ordinary forming and sheet-metal fabrication.
• SPCD: For applications requiring improved stamping and forming performance.
• SPCE: For deeper drawing operations involving more demanding forming requirements.
• DC01: A general cold-forming grade for common sheet-metal components.
• DC03: For more demanding cold-forming applications.
• DC04: For deeper drawing requirements.

SPCC, SPCD and SPCE belong to the JIS grade system, while DC01, DC03 and DC04 belong to the EN cold-forming steel grade system. ASTM A1008 is another applicable cold-rolled sheet specification. The grade and governing standard should be specified together when requesting a quotation.

Match the Surface to the Finished Component

A matte finish provides a subdued, low-gloss appearance. A bright finish has a brighter, more reflective appearance. This distinction matters when the steel surface remains visible on the finished component.

For parts that will be painted or receive another surface treatment, specify the required surface condition and oiling status alongside the intended finishing process. This gives the material selection and incoming inspection a clear surface requirement.

Coil Configuration and Processing Requirements

Coil configuration affects compatibility with decoiling equipment, material handling and downstream production.

Two coil inner diameters commonly referenced for cold rolled steel coil selection are 508 mm and 610 mm. The required inner diameter should be confirmed against the customer's equipment. Coil weight, outer diameter and edge condition should also be specified according to handling, storage and transportation requirements.

If narrower material is required, include the finished width and dimensional tolerances in your inquiry. Slitting and width adjustment are listed among the processing options in our steel-strip product range; their suitability for a specific cold rolled coil order can be reviewed when the requirements are confirmed.

Customers can also specify an oiling requirement for consideration. This should be matched to storage and transportation conditions and to any cleaning, painting or coating process planned after delivery.

Applications and Material Matching

Matte finish cold rolled steel coil can be considered for a range of formed metal products. The appropriate grade and surface requirements depend on the component design and production process.

For ordinary fabrication, SPCC and DC01 are possible starting points. Where a component requires more demanding stamping or deeper drawing, SPCD, SPCE, DC03 or DC04 can be evaluated against the actual forming conditions.

Manufacturing, Quality Control and Supply Support

Established in 2012, Shanxi Midas Industrial Co., Ltd. is based in Shanxi, China. Our factory covers 600,000 m², with a building area of 10,000 m². Our steel product range includes cold rolled steel coils, carbon steel coils, steel strips, steel plates, galvanized steel products and structural steel products.

This range gives customers access to several categories of steel materials through one supplier. We support the purchasing process with product selection, technical communication, quotations, order confirmation, production updates, inspection information and after-sales feedback.

For cold rolled steel coil orders, the main quality points to establish are:

• Dimensions: Thickness, width and the dimensional tolerances specified for the order.
• Surface appearance: Scratches, visible defects and consistency with the agreed matte finish.
• Material properties: Relevant mechanical properties for the selected grade and applicable standard.
• Coil condition: Inner diameter, coil configuration, edge condition and any agreed oiling requirement.
• Batch documentation: Material identification, MTC and other inspection records agreed for the order.

Confirming material specifications and inspection criteria before shipment helps align the supplied coil with the customer's receiving and production requirements.

For export orders, packaging and coil protection can be arranged according to the shipment route, storage period and handling requirements. Packaging and inspection details are confirmed as part of the order.
