Grade 700 Hot Rolled Rectangular Hollow Section 50×100×2.0×6m

1. Product Overview

This is Grade 700 hot rolled high-strength rectangular hollow section (RHS), sized 50mm×100mm with 2.0mm wall thickness and 6m fixed length. It is made of hot rolled high-strength base strip with original hot rolled black surface. The base material adopts controlled rolling and controlled cooling process for refined grain structure and stable mechanical performance with excellent bending resistance. It is a lightweight load-bearing structural material for trailer and engineering machinery export, suitable for bulk cargo shipment.

2. Application Scenarios

• Frame and sub-beam of semi-trailer cargo box, support structure for van trucks, realizing vehicle weight reduction and higher payload capacity
• Frames, supports and guardrails for mining engineering machinery, suitable for rough and heavy-load working conditions in mining areas
• Heavy-duty supports for ports and large-scale load-bearing warehouse frames
• Agricultural machinery, heavy-duty photovoltaic brackets and light long-span steel structures
• Structural components for infrastructure and mining projects in Africa and Southeast Asia

3. Core Advantages

• Stable performance with hot rolled high-strength Grade 700 raw material. Controlled rolling & cooling process brings high yield strength, good toughness, fatigue and impact resistance, resisting deformation under heavy load
• Outstanding lightweight performance. Lighter weight than ordinary Q355 tubes under the same load requirement, lowering vehicle dead weight and fuel consumption
• Good workability. Uniform material for easy cutting, punching, assembly and painting without weld cracking
• Regular section with tight tolerance. Good straightness and flat end face for high matching accuracy in mass assembly
• Suitable for bulk export. 6m fixed length for stable stacking and easy loading & unloading for bulk transport
