Premium Quality Square Steel Tubes: Superior Corrosion Protection, Structural Strength & Precision Engineering for Industrial Applications
Unmatched Quality in Square Steel Tubing
Dongpeng Boda Steel Pipe Group specializes in manufacturing high-performance square steel tubes for construction, infrastructure, and industrial applications. Our product range includes hot-dipped galvanized square tubes, mild steel square tubes, ASTM A500 compliant tubes, ERW square tubes, and standard 38x38mm square tubes – all engineered for durability, precision, and cost-efficiency.
1. Hot-Dipped Galvanized Square Tube – Ultimate Corrosion Resistance
Our hot-dipped galvanized square tubes undergo a rigorous zinc-coating process, ensuring superior protection against rust, moisture, and harsh environmental conditions. Ideal for:
Outdoor structures (fencing, railings, signage)
Industrial frameworks (support beams, machinery guards)
Infrastructure projects (bridges, highway barriers)
Why Choose Dongpeng Boda?
Thick, uniform zinc coating for extended lifespan
Compliant with international corrosion resistance standards
Available in custom sizes and thicknesses
2. Mild Square Tubes – Versatile & Cost-Effective
For general fabrication and light structural applications, our mild steel square tubes offer excellent weldability and machinability. Common uses include:
Furniture & shelving
DIY projects & interior frameworks
Temporary construction supports
Key Advantages:
Smooth surface finish for painting or powder coating
High strength-to-weight ratio
Competitive pricing for bulk orders
3. ASTM A500 Square Tube – Structural Integrity Guaranteed
Engineered for heavy-load applications, our ASTM A500 square tubes meet rigorous U.S. standards for structural steel tubing. Suitable for:
Building construction (columns, trusses)
Warehouse & factory frameworks
Transportation equipment (trailers, racks)
Dongpeng Boda’s Commitment:
Strict adherence to ASTM A500 Grade B/C specifications
Superior yield strength and load-bearing capacity
Third-party tested for consistency
4. ERW Square Tube – Precision-Welded for Consistency
Our ERW (Electric Resistance Welded) square tubes provide seamless joints and dimensional accuracy, making them ideal for:
Automotive chassis
Agricultural equipment
Architectural metalwork
Why Our ERW Tubes Stand Out:
High-frequency welding ensures strong, defect-free seams
Excellent roundness and straightness tolerances
Available in multiple wall thicknesses
5. 38x38mm Square Tube – The Standard for Reliability
A popular choice across industries, our 38×38 square tubes balance strength and workability. Applications include:
Handrails & safety barriers
Machine frames & conveyor systems
Retail displays & exhibition stands
Customization Options:
Cut-to-length services
Pre-drilled or punched holes upon request
Multiple surface treatment options (galvanized, painted, or bare)
