Hot Rolled Steel Strip

Hot Rolled Steel Strip

1．Product Overview

Hot rolled steel strip is suitable for narrow-width processing where medium-gauge thickness and stable strip geometry are required for downstream fabrication. Compared with wide hot rolled coil, strip material in the 30–630mm width range is more suitable for slitting, bending, profiling, welded strip blanks, and general fabricated strip components.

This specification covers 1.0–5.0mm thickness with mill edge and slit edge options. It is suitable for strip-based production routes where handling efficiency, secondary conversion, and narrower width control are important.

2．Technical Solution

The product is supplied as hot rolled steel strip under JIS G3131, GB/T 700, SAE, and DIN1623 systems. The available grades include SPHC, Q195, Q235, Q345, SAE1006, SAE1008, and ST12, which can be selected according to downstream forming route and market requirement.

The strip is supplied with 508mm coil ID and around 0.7–5MT coil weight, which is suitable for standard strip handling, recoiling, and secondary processing. Mill edge and slit edge are both available, and the minimum slit width is 30mm for narrow-width routing.

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.
