Q235 Hot Rolled Steel Sheets

We supply 4mm and 10mm Q235 hot rolled carbon steel sheets in stock, manufactured in strict accordance with GB/T 700 national standard. As a high-quality common carbon structural steel, Q235 steel features a yield strength of no less than 235MPa, with excellent ductility, stable hardness, superior weldability and bending performance. It is widely recognized and highly cost-effective for construction, steel structure fabrication, machinery manufacturing and infrastructure projects across Southeast Asia.

The two mainstream thicknesses (4mm & 10mm) fully meet the mainstream processing demands of small and medium-sized steel structures, infrastructure decoration, equipment bases, box frames and guardrail supports in Southeast Asian markets. Our steel sheets feature flat surface, uniform oxide layer and high cutting precision, supporting custom cutting, punching and welding to reduce processing costs and shorten construction cycles for customers.

Grade: Q235B (most versatile grade for Southeast Asian engineering projects)

Standard: GB/T 700-2006, equivalent to international SS400 & A36 standards, compliant with local project acceptance requirements in Southeast Asia

Thickness: 4mm, 10mm (custom cutting & sizing available)

Size Range: Width 1000-2000mm, Length 2000-12000mm, non-standard sizes customizable

Mechanical Properties: Yield Strength ≥235MPa, Tensile Strength 375-460MPa, stable toughness and strong deformation resistance

Processing Feature: High-temperature hot-rolled, uniform metallographic structure, smooth surface, no cracks, bubbles or delamination defects

1. Strong Durability for Tropical Climate

Specially adapted to the high-temperature, high-humidity and rainy tropical climate of Southeast Asia. The hot-rolled process ensures a dense surface structure, delivering excellent oxidation and moisture corrosion resistance. The sheets are not easy to deform or rust for long-term outdoor application, ideal for open-air buildings and mechanical equipment.

2. Excellent Machinability & Cost-saving

Q235 steel boasts outstanding bending, welding, punching and cutting performance. It can be easily processed with ordinary equipment, perfectly matching the production capacity of small and medium-sized processing factories in Southeast Asia, greatly improving processing efficiency.

3. Standard Quality & Wide Compatibility

All products undergo strict factory inspection with qualified chemical composition and mechanical properties. We can provide complete material certificates and quality inspection reports, fully compliant with local engineering standards for infrastructure and mechanical supporting projects.

4. Sufficient Stock & Stable Supply

A large number of 4mm and 10mm Q235 hot rolled steel sheets are in permanent stock. We support bulk orders and mixed batch shipment, with fast sea freight delivery to Malaysia, Thailand, Vietnam, Indonesia, Philippines and other Southeast Asian countries. Custom processing services are available.
