ZSJH
Hollow steel profiles provide a practical solution for structures that require strength, dimensional stability and efficient use of steel. Their enclosed cross-sections deliver reliable performance while creating smooth surfaces for welding, connection and architectural finishing.
ZSJH Steel supplies SHS, RHS and CHS products for structural steel fabricators, contractors, equipment manufacturers and building material distributors. Customers can order standard sections or customized products prepared according to cutting lists and fabrication drawings.
From raw steel supply to processed components, we help international buyers simplify purchasing, fabrication and project delivery.
Square profiles provide similar structural behavior along both main axes. They are frequently selected for columns, support frames, posts and modular structures.
Rectangular profiles are suitable for applications where bending strength is required mainly in one direction, including beams, roof members and equipment frames.
Circular profiles distribute loads evenly around the section and are widely used in towers, trusses, columns and visually exposed structures.

Buyers can combine square, rectangular and circular hollow sections in one purchasing plan, reducing supplier management and communication costs.
Sections can be cut according to the customer’s bill of materials, helping reduce on-site cutting, scrap and labor requirements.
Connection plates, base plates, brackets and stiffeners can be welded to the profiles before delivery when detailed drawings are provided.
Galvanizing and paint systems can be selected according to the installation environment instead of applying one standard finish to every project.
Bundles are prepared for lifting, container loading and long-distance sea transportation. Packing can be adjusted according to unloading conditions at the destination.

Hollow sections are normally arranged in compact steel bundles and secured with metal straps. Depending on the project, we can also provide:
Waterproof wrapping
Protective end covers
Timber supports
Bundle separation
Component identification
Loading sequence planning
Customized container packing
Container loading plans can be optimized according to profile length, bundle weight and destination unloading conditions.
