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)
