SPHC Hot Rolled Steel Coil

Overview of SPHC Hot Rolled Steel Coil

SPHC is a commercial-quality hot-rolled mild steel grade specified under the JIS G 3131 Japanese industrial standard. The designation “S” represents steel, “P” for plate/sheet, “H” for hot-rolled, and “C” for commercial quality. SPHC is the most widely utilized hot-rolled carbon steel for general-purpose applications, offering an exceptional combination of cost-efficiency, reliable mechanical performance, and superior processability. It serves as the fundamental material for a vast range of industrial components that require basic forming, bending, and high-integrity welding.

Shandong Tanglu Metal Material Co., Ltd. supplies premium SPHC hot-rolled coils in a broad range of thicknesses and widths. Our SPHC material is characterized by its consistent chemical composition and uniform mechanical properties, ensuring predictable behavior during stamping and fabrication. For B2B buyers in the automotive, construction, and appliance manufacturing sectors, SPHC provides a versatile and reliable substrate that balances structural stability with ease of manufacturing, making it the primary choice for large-scale industrial production.

Key Features and Fabrication Advantages

The defining advantage of SPHC is its excellent ductility and formability for commercial-grade applications. With a minimum tensile strength of 270 MPa, it provides the necessary structural capacity for secondary parts and general enclosures. One of the most critical engineering benefits of SPHC is its outstanding weldability; its low carbon and manganese content ensure that it can be easily joined using all standard industrial welding processes (arc, MIG, TIG) without the risk of hardening or cracking in the heat-affected zone.

Shandong Tanglu offers SPHC coils in both “Black” (mill scale) and “Pickled & Oiled” (P&O) surface conditions. The P&O treatment removes the surface oxides, providing a clean, smooth finish that is ideal for precision stamping, laser cutting, and subsequent coating or painting processes. Every SPHC coil from Tanglu is delivered with original Mill Test Certificates (MTC) documenting compliance with JIS G 3131, including detailed chemical analysis and tensile property data, ensuring full material traceability for international quality management systems.

Main Applications of SPHC Steel Coil

SPHC is the industry workhorse for a diverse array of manufacturing and construction sectors. It is primarily used for the fabrication of structural components in the automotive industry, such as inner panels, brackets, and frame reinforcements. In the construction sector, it is a vital material for producing welded pipes and tubes, light-gauge structural sections, and specialized hardware components.

Beyond automotive and construction, SPHC is extensively utilized in the appliance and furniture industries for manufacturing cabinet shells, shelving systems, and internal structural supports. It is also an indispensable choice for general engineering applications, including the production of electrical enclosures, small material-handling parts, and hardware accessories. Due to its proven versatility and excellent cost-performance ratio, SPHC remains the trusted global standard for commercial-quality hot-rolled mild steel coils.
