Hot Rolled Rectangular Tube 100×180×8.0 (High Strength 700)

1. Product Overview

This is a hot rolled rectangular tube made of high strength 700 steel, size 100×180×8.0mm. It is a high-strength hollow structural section with straight tube body and uniform internal structure. It features high strength and light self-weight, with original hot-rolled black surface. It is widely used for heavy-load export projects of trailers and engineering machinery, and can be further treated with rust removal or painting for anti-corrosion.

2. Application Scenarios

• Chassis frame and beam for semi-trailers and dump trucks (preferred high-strength material in Liangshan trailer industry)
• Support frames and load-bearing structures for mining equipment
• Heavy-duty platforms, equipment bases and support structures at ports
• Trailer manufacturing, freight trailers and special vehicle structural parts for overseas markets
• Heavy-load steel structure supports and large load-bearing frames

3. Core Advantages

1. Made of high strength 700 steel. High yield strength helps reduce dead weight of vehicles while maintaining load capacity, so as to improve cargo carrying capacity. It is the preferred high-strength steel for trailer industry.
2. Hot rolled forming with even wall thickness, excellent bending and torsion resistance, not easy to deform under heavy load and bumpy working conditions.
3. Good weldability, easy for cutting, punching and splicing, suitable for processing in overseas workshops.
4. Stable specifications and sufficient stock for bulk export orders.
5. Better strength performance compared with ordinary Q235 / Q355 profiles, with competitive overall material cost.
