Linear Slot Black Rectangular Steel Tube

For industrial and architectural applications that demand both structural integrity and modular flexibility, finding the right framing component is crucial. Our precision-engineered Black Rectangular Tube with Vertical Slot provides the ideal solution. This component is designed to facilitate easy assembly and adjustment in construction projects, exhibition stands, machine guards, and workspace furniture. Its sleek, black finish offers a professional appearance while the integrated slot system allows for versatile connectivity. We also manufacture this versatile profile as a Black Rectangular Pipe with Straight Opening, ensuring a perfect fit for various bolted joint designs and mounting requirements.

Engineered from high-quality steel, this tube is built for durability and load-bearing performance. The linear slot, a defining feature, is machined with high precision to guarantee consistent alignment when connecting brackets, panels, or other accessories. This product is synonymous with our Vertical Slotted Black Rectangular Hollow Tube, offering the same reliable structural properties. For designs requiring clean lines and customized fixture points, our profile is also available as a Black Rectangular Tube with Linear Cut, providing ultimate design freedom for engineers and fabricators.

The Linear Slot Black Rectangular Steel Tube is manufactured to exacting standards, ensuring consistent quality and performance across every batch. The steel used is typically a low-carbon, high-strength grade, which is first formed into a rectangular hollow section (RHS) before undergoing the critical slotting process. This slot is precision-cut using laser or plasma technology to achieve clean, burr-free edges, which is essential for smooth assembly and safety during handling. Following forming and slotting, the tube undergoes a surface preparation process and is finished with a durable black powder coating or paint. This coating not only enhances corrosion resistance, protecting the tube from rust and environmental wear in both indoor and select outdoor applications, but also provides a uniform, matte-black aesthetic that is both modern and professional.

Key dimensions and mechanical properties for common sizes are listed below. All tubes are supplied in standard 6-meter (approx. 20-foot) lengths, with custom cutting services available.
