Detail Information
Rectangular Hollow Sections

Rectangular hollow section is a rectangular steel tube made from steel coils or billets through a special forming process. Rectangular hollow sections have excellent support properties, good weldability and so on. Rectangular hollow sections are widely used in building structures and machinery manufacturing. Rectangular steel pipes produced by Yuantai Derun not only have more complete product size specifications, but also have tighter weld seams, excellent physical and mechanical properties, and the price is also very affordable.

Bright And Clean Surface

Bright And Clean Surface

The inner and outer walls of the rectangular hollow section are flat and smooth,it has very right and clean surface.

The surface of the rectangular hollow section is free of rust, clean and hygienic, without pits or burrs. The inner wall weld seam is clean, round and full, and the surface of the hollow section does not hurt hands when touched.

Hollow Section End No Burrs

In order to prevent burrs on the rectangular hollow section ends from injuring people, the rectangular hollow section ends of Yuantai Derun are all polished by technicians before leaving the factory, ensuring both aesthetics and safety during secondary lifting.
Hollow Section End No Burrs
Uniform Thickness

Uniform Thickness

A qualified rectangular hollow section must have a uniform wall thickness. It is very important in subsequent applications. The uniform wall thickness of the rectangular hollow section ensures that it receives even force when carrying heavy loads, without any weak points in load-bearing capacity, making the steel structure or weighing structure more stable.

Tight Weld

At Yuantai Derun, the welding seams of rectangular hollow sections are tighter and stronger. In addition to advanced equipment and the support of engineers' processes, it is also related to the quality of welding flux used by Yuantai Derun. The welding materials we use are more compatible with the steel hollow section base material, and the welding seams are highly integrated with the base material, greatly reducing the risk of cracking of rectangular hollow sections.
Tight weld

Making Process

1. Direct molding technology
At Yuantai Derun, advanced direct molding technology is used for rectangular hollow sections, especially for large-diameter rectangular hollow sections, which is leading the industry.
2. Round before forming technology
Yuantai Derun adopts advanced round before forming technology, which is completed in the same unit, greatly improving production efficiency.
3. Circular to Square Forming Technology
The technical process of first making circular tubes and then placing them in the round to square conversion unit for reshaping. This mainly targets rectangular hollow sections with extra large diameters, and all three molding technologies are leading in the world.

Application

1. In the field of architecture:
Rectangular hollow sections can be used for structural support in buildings, such as beams, columns, etc. Their unique shape and strength characteristics enable rectangular hollow sections to withstand large loads, ensuring the stability and safety of buildings. In addition, rectangular pipes can also be used for exterior wall decoration of buildings. Through different surface treatments and coatings, buildings can be made more beautiful and durable.
2. Mechanical manufacturing and shipbuilding:
Rectangular hollow sections are widely used in manufacturing machinery and industrial equipment, including conveyor belts, pipelines, and storage equipment such as tanks and warehouses. Its flat internal surface and large cross-sectional area can improve the efficiency of material transportation, while its strength and sealing performance can ensure the safe storage of materials.
3. Hardware and steel structure engineering:
Rectangular hollow sections are used in hardware products and steel structure engineering. Their bending and torsional strength is comparable to circular hollow sections, but they are lighter in weight. Therefore, they are widely used in the manufacturing of mechanical parts and engineering structures. In addition, rectangular steel hollow sections belong to special-shaped tubes and are widely used in various structural components, tools, and mechanical parts, which can greatly reduce structural weight and save steel.

FAQ

How to remove the internal stress of a rectangular hollow section?
At Yuantai Derun, there is residual internal stress around the welds of rectangular hollow sections produced using welding technology. To address this issue, Yuantai Derun has long been equipped with a heating furnace, which greatly reduces the internal stress of the rectangular hollow sections after heating treatment.
When do you need a custom seamless rectangular hollow section?
Seamless rectangular hollow sections are often custom-made because different applications require different specifications and materials.
1. Specifications: If the square tube size, thickness, width, or length is not standard, you can customize it.
2. Special material requirements: Some applications require special materials, such as 20Cr alloy steel or other special materials. Customization ensures the use of suitable materials.
3. Processing services: If the square tube needs to be processed, customization can ensure it meets specific usage requirements.
4. Quality assurance: For some applications that have special quality requirements, customization can ensure the square tube meets the standards.
Normally, welded rectangular hollow sections and seamless rectangular hollow sections are universal. However, when you encounter the four situations mentioned above, you will have to customise seamless rectangular hollow sections.
Can I start with a test order for a rectangular hollow section?
Of course, the fact is that most of our rectangular hollow section partners start with a trial order. Don't hesitate to contact us.
What are the unique rectangular hollow section properties?
The rectangular hollow section has the following unique characteristics:
1. Better stability
Compared to square hollow sections, circular hollow sections, rectangular hollow sections have better stability when placed horizontally on one side of the long side.
2. Some special structures have more decorative and supportive effects
On some spatial structures that are only suitable for rectangular hollow sections, replacing them with hollow sections of other shapes cannot achieve the decorative and supporting effects of rectangular hollow sections.
