PRODUCT INTRODUCTION

ASTM A283 Grade A/B/C/D Carbon Steel Coils are low-carbon steel coils for structures that comply with the standards of the American Society for Testing and Materials (ASTM), and are designed for general industry and construction. This series of products covers four strength grades (A, B, C, D), manufactured through a hot rolling process, with excellent formability, welding performance and moderate tensile strength (Grade A-D strength range: 310-485 MPa), which can meet diverse engineering needs. The surface is smooth and uniform, and the thickness tolerance is strict, which is suitable for further processing (such as cutting, stamping, bending), and provides uncoated or customized surface treatment options (such as sandblasting, galvanizing). All products are quality tested by a third party to ensure that the chemical composition (carbon, manganese, sulfur, phosphorus content) and mechanical properties meet the ASTM A283 standard certification.

PRODUCT FEATURES

Multi-grade coverage:

Grade A (lowest strength) is suitable for light load scenarios, and Grade D (highest strength) meets higher load-bearing requirements. Customers can flexibly choose according to project budget and performance requirements.

Process adaptability:

Hot rolling process provides good surface quality and reduces subsequent processing costs; supports customized sizes (thickness: 1.2mm-25.4mm, width: ≤2000mm).

Compliance guarantee:

Provide Mill Test Certificate (MTC) and third-party inspection reports to ensure material traceability and meet global engineering project bidding requirements.

APPLICATION

1.Building and Infrastructure

• Steel building frames, roof supports, bridge components.

• Non-pressure vessel structures such as storage tanks, silos, and pipe supports.

2.General manufacturing

• Agricultural machinery, conveying equipment, and material handling system housings

• Transportation equipment such as truck chassis and trailer components

3.Medium and low pressure container manufacturing

• Grade C/D steel coils can be used for low pressure liquid or gas storage tanks (must comply with ASME standard supplementary requirements)

4.Energy and public facilities

• Power towers, substation structures, ventilation ducts

• Water treatment system support frames

5.Customized processing areas

• Production of hardware and connectors through secondary processing such as cold rolling and stamping
