Striped Rectangular Hollow Section

Stripe Rectangular Hollow Section is a modern and versatile structural component, prized for its distinctive appearance and robust functionality. It finds extensive application in contemporary construction, architectural design, industrial frameworks, and creative fabrication projects. The key advantage of this product lies in its combination of a classic rectangular profile with a unique striped surface finish, which adds visual texture and can help mask minor surface imperfections. This makes it a popular alternative to standard profiles like the Black Rectangular Steel Tube. The finish is more than aesthetic; it provides a consistent, non-reflective surface that is ideal for both visible structural elements and final applications where a uniform look is required, similar to a Black Finished Rectangular Tube. As a type of hollow structural section (HSS), its closed shape offers excellent strength-to-weight ratios, making it efficient for load-bearing purposes. Whether you refer to it as a Black Rectangular Pipe or a Striped Rectangular Steel Pipe, this product delivers reliable performance with enhanced visual appeal, suitable for railings, furniture, exhibition stands, and support structures.


The manufacturing process for the Striped Rectangular Hollow Section involves forming high-quality steel into a precise rectangular shape with a hollow interior. This is followed by a specialized finishing technique that creates the signature striped texture on the surface. This texture is integral to the material and does not compromise its structural integrity. The Striped Rectangular Hollow Section is available in a wide range of sizes and gauges, allowing engineers and designers to select the optimal profile for their specific strength and dimensional requirements. Its geometric shape provides predictable and stable mechanical properties, including high torsional resistance and good bending strength in both principal axes. The hollow core also offers practical benefits, such as the ability to route utilities (wires, conduits) internally in certain applications, contributing to cleaner designs. Furthermore, the material is typically supplied with a protective coating or is readily paintable, allowing for additional customization and corrosion protection to suit various environmental conditions.

  • Galvanized Cold-Rolled Seamless Steel Pipe

    Galvanized Cold-Rolled Seamless Steel Pipe

    Xinlida's China Galvanized Cold-Rolled Seamless Steel Pipe is a seamless steel pipe produced by the cold-rolling process. Compared with hot-rolled steel pipes, the cold-rolling process endows it with higher precision and better surface quality. The wall thickness of its pipes is uniform and the dimensional accuracy is high. Generally, the outer diameter tolerance is controlled within ±0.1mm, and the wall thickness tolerance is about ±0.05mm. It can meet the demands of high-precision processing. Meanwhile, the surface of cold-rolled seamless steel pipes is smooth, which reduces the resistance of fluid flow in the pipeline and improves the transportation efficiency. They are widely used in industries such as petroleum, natural gas, chemical engineering, boilers, and mechanical manufacturing.
