JIS G 3131 SPHC, SAE 1006, SAE 1008 Hot Rolled Steel Coils With Coil ID 508mm

JIS G 3131 SPHC, SAE 1006, SAE 1008 Hot Rolled Steel Coils With Coil ID 508mm

1．Product Overview

Hot rolled steel strip is suitable for narrow-width processing where medium-gauge thickness, stable strip geometry, and standard coil build are required. This specification covers 1.0–5.0mm thickness and 30–630mm width, which is suitable for recoiling, slitting, bending, profiling, and other strip-based fabrication routes.

Compared with wide hot rolled coil, strip material in this size range is more practical for downstream conversion into narrower sections and formed components. The product is supplied with 508mm coil ID and around 0.7–5MT coil weight for standard strip handling and secondary processing.

2．Technical Solution

The product is supplied under JIS G3131 SPHC, GB/T 700 Q195/Q235/Q345, SAE1006/SAE1008, and DIN1623 ST12 systems. This allows the strip to match different market requirements and processing routes while keeping the material within a hot rolled strip specification.

Mill edge and slit edge are available. Edge condition affects trimming allowance, recoiling route, and downstream profile quality, especially when the strip is processed into narrower widths. For slit strip supply, the minimum width is 30mm.

3．Specifications

4．Application

• This material is suitable for hot rolled strip processing routes that require narrow widths rather than wide coil supply.
• It can be used for recoiling, slitting, bending, profiling, welded strip blanks, structural strip components, and general fabricated strip parts.
• For medium-gauge strip applications, this size range is practical for downstream handling, storage, and conversion.

5．Processing

• The strip can be supplied with mill edge or slit edge according to downstream requirement.
• It is suitable for recoiling, slitting, cut-to-length conversion, bending, and general forming.
• For narrower strip production, slit width should be controlled above 30mm.

6．Advantages

• The 1.0–5.0mm thickness range is suitable for medium-gauge hot rolled strip applications.
• The 30–630mm width range supports narrow strip processing rather than wide-coil routing.
• Mill edge and slit edge options allow the strip to match different processing routes.
• Around 0.7–5MT coil weight is practical for strip handling and secondary processing.
• The available grade system covers JIS, GB, SAE, and DIN equivalents for broader application matching.

7．How to Choose

• Choose SPHC when the application follows general JIS hot rolled strip logic.
• Choose Q195 or Q235 when the route follows GB-based general commercial strip use.
• Choose Q345 when higher strength level is required within the listed grade system.
• Choose SAE1006 or SAE1008 when the downstream process is aligned with SAE-based material routing.
• Choose slit edge when final narrow-width processing and edge control are important, and choose mill edge when original edge condition is acceptable in the downstream route.
