Hot-Dip Galvanized Square & Rectangular Steel Pipe (SHS/RHS)

Our Hot-Dip Galvanized Structural Hollow Sections (SHS/RHS) are manufactured from high-quality ERW carbon steel tubes and coated with a protective zinc layer in full compliance with ASTM A500, EN 10219, and AS/NZS 1163 standards.

Designed for commercial building framing, solar panel mounting structures, fencing, and general engineering applications, our galvanized square and rectangular tubes provide an excellent balance of structural strength, corrosion resistance, and cost efficiency for global buyers.

Technical Specifications & Manufacturing Capabilities

Below are the standard engineering parameters and material grades for our structural galvanized square and rectangular tubes:

Key Advantages for Global Engineering Projects

1. Reliable Anti-Corrosion Defense

·Uniform Zinc Production: The hot-dip galvanizing process ensures both internal and external surfaces are thoroughly coated, protecting the steel frame against rain, moisture, and mild atmospheric corrosion.

·Long Service Life: Provides decades of reliable performance without requiring expensive field painting or frequent maintenance.

2. Precision Fabrication & Custom Cuts

·Custom Lengths: Cut precisely to 5.8m / 5.85m for 20ft containers or 11.8m / 12.0m for 40ft containers to minimize waste and optimize shipping costs.

·Pre-Punching Available: Factory pre-drilled holes according to your structural drawings for rapid, bolt-together assembly on site.

3. International Standard Compliance

·Produced in full accordance with international building codes, making our pipes readily acceptable for public infrastructure, industrial warehouses, and agricultural framing worldwide.

Typical Structural Applications

·Solar & Energy Infrastructure: Ground-mounted solar panel racking, wind turbine support frames, and transmission tower supports.

·Commercial Building Construction: Airport terminal framing, curtain wall supports, structural columns, and steel trusses.

·Heavy Transportation & Highway: Guardrail posts, sign gantries, bridge decking supports, and trailer chassis frames.

Seaworthy Export Packaging & Container Loading via Tianjin Port

To prevent white rust and transit bending during ocean shipping, our square and rectangular pipes are packed with extreme care:

·Hexagonal Bundle Packaging: Bundled with high-tensile steel straps and protective sling belts for safe crane handling.

·Anti-Rust Water Wrapping: Wrapped with inner VCI anti-corrosion film and outer woven waterproof tarpaulin.

·6m & 12m Container Optimization: Cut precisely to 5.8m/5.85m (for 20ft containers) or 11.8m/12.0m (for 40ft/40HQ containers) to maximize container weight limits up to 26–27 Metric Tons.

Frequently Asked Questions (FAQ)

Q1: What is the difference between SHS, RHS, and CHS?

A: These are acronyms for structural hollow sections: SHS stands for Square Hollow Section, RHS for Rectangular Hollow Section, and CHS for Circular Hollow Section. We supply all three with heavy hot-dip galvanized finishes.

Q2: What is the difference between pre-galvanized and hot-dip galvanized square tubes?

A: Pre-galvanized tubes are roll-formed from pre-galvanized steel strips (lower cost, typical zinc layer $40-120{\text{ g/m}}^2$40−120 g/m2). Hot-dip galvanized tubes are dipped into molten zinc after welding, offering higher zinc protection ($180-275+{\text{ g/m}}^2$180−275+ g/m2) and full weld-seam coverage for outdoor structures.
