Galvanized Rectangular Hollow Section

Superior Corrosion Resistance
Available in Pre-Galvanized (60-150g/m²) and Hot Dip Galvanized (200-400g/m²) options. The robust zinc barrier significantly extends service life and drastically reduces long-term maintenance costs in harsh environments.
Optimized Strength-to-Weight Ratio
The hollow rectangular profile maximizes bending and torsional resistance while minimizing structural mass. This directly lowers transportation expenses and simplifies on-site installation.
Precision Engineering & Fabrication
Manufactured via strict ERW and cold-forming processes to guarantee uniform wall thickness and smooth weld seams. The flat surfaces allow for faster, more cost-effective cutting, drilling, and welding.
Cost-Efficient Lifecycle
Combines high initial structural integrity with minimal upkeep requirements. The durable finish prevents rust degradation, ensuring reliable performance and lowering total project ownership costs.
Versatile Customization
Fully adaptable to specific project demands with bespoke dimensions, customized zinc coating thicknesses, and professional processing services including cut-to-length and export-standard bundling. 

Steel Structure Buildings
Primary load-bearing columns, beams, and trusses for industrial warehouses, commercial skyscrapers, and heavy-duty steel frameworks.
Solar Mounting Systems
Robust and weather-resistant structural supports for photovoltaic (PV) panel arrays, ensuring long-term stability in outdoor environments.
Infrastructure & Guardrails
Highway isolation barriers, bridge supports, and pedestrian guardrails requiring high impact resistance and anti-corrosion performance.
Agricultural Facilities
Structural frameworks for multi-span greenhouses, livestock breeding pens, and automated irrigation systems exposed to high-humidity conditions.
Machinery & Equipment Frames
Precision structural bases and protective enclosures for heavy industrial machinery, agricultural equipment, and automated assembly lines.
Fencing & Security Systems
Durable perimeter fencing, security gates, and modular guardrail systems for residential, commercial, and industrial zones. 

We provide end-to-end tailored solutions to meet specific project demands:

Dimensional Customization
Bespoke width, height, wall thickness, and cut-to-length services.
Surface & Packaging
Custom zinc coating thickness, surface marking, and export-standard waterproof bundling.
Supply Chain Reliability
Direct factory supply from China (Tianjin/Shandong). Major shipping ports include Xingang and Qingdao, with typical delivery times of 15-30 days depending on order volume.
