Product introduction

Product Title

ERW HFW Structural Tube 76mm-660mm Exhibition Hall Steel Frame Pipe / High Frequency Welded Round Structural Pipe for Exhibition & Convention Hall Steel Structure Frame

Brief Introduction

ERW HFW Exhibition Hall Structural Tube is high-frequency welded round structural steel pipe specially designed for exhibition hall, convention center and large exhibition venue steel frame construction. Manufactured by mature HFW high-frequency resistance welding technology, the outer diameter covers the full range from 76mm to 660mm.

This structural tube features high compressive strength, good bending resistance and excellent weld integrity, meeting the load-bearing requirements of large-span exhibition hall steel frames, support columns, trusses and space frame structures. Online normalization eliminates welding residual stress, ensuring stable mechanical performance under static and wind loads. The pipe has tight dimensional tolerance, smooth surface and is easy for cutting, welding, drilling and spraying finishing. Available in black bare pipe or customized surface treatments including anti-rust primer, zinc rich primer and hot-dip galvanized. Custom fixed-length pre-cut service is supported to speed up on-site steel frame assembly. It is the preferred tubular material for large exhibition centers, expo pavilions and temporary & permanent exhibition venue steel structures. Hebei Huayang carries out full mechanical property testing to guarantee structural safety for exhibition building projects.

Production Process & Structural Performance

Structural-Grade Raw Material Selection We select hot rolled structural steel coils with stable tensile and yield strength. Raw materials are inspected for chemical composition and mechanical properties before production to ensure the base metal can withstand dead load, live load and wind load of large exhibition hall buildings.

HFW High Frequency Forming & Welding Continuous multi-pass rolling forms round tube. High-frequency welding without filler metal, inner and outer welding flash is removed by online scarfing. The weld is metallurgically bonded, achieving strength matching the base material, critical for large span exhibition steel frames.

Online Weld Normalization Heat Treatment This key process relieves welding residual stress and refines grain structure. It avoids weld cracking and deformation under long-term static load and temperature variation, ensuring the safety and stability of exhibition hall steel trusses and support frames.

Sizing, Straightening & Custom Cutting Multi-stand sizing mill controls OD and roundness tolerance. Full-length straightening reduces pipe bending. Pipes can be pre-cut to project fixed lengths, deburred and chamfered, convenient for on-site assembly and welding of exhibition steel frame.

Full Batch Structural Inspection 100% online ultrasonic inspection for weld seams. Each batch undergoes tensile test, bending test and impact test to verify structural mechanical performance. Hydrostatic test is available upon request. All test records and MTR reports can be supplied for structural engineering acceptance.

Packaging, transportation and delivery

Packaging, transportation and delivery

At Hebei Huayang Steel Pipe Co., Ltd., we apply standardized and reliable packaging solutions for all our steel pipe products. Our pipes can be securely packed by hexagonal bundling or circular bundling according to product diameter, wall thickness and customer requirements. Each pipe end is protected with high‑strength plastic pipe caps to avoid collision damage, dust and moisture during transportation and storage. The whole bundle is firmly wrapped with durable woven bags to enhance stability and prevent scratches or deformation.

We support a complete range of transportation methods to satisfy global customers, including road transportation, railway transportation, sea freight and container shipping. Based on our strategic location in Cangzhou, Hebei Province, we enjoy convenient access to major ports such as Tianjin Port, which greatly improves logistics efficiency and reduces transportation costs.
