Vertical Slotted Black Rectangular Hollow Tube

Our premium Black Rectangular Tube with Vertical Slot is engineered for demanding applications requiring both structural integrity and versatile mounting capabilities. This product, also known as a Linear Slot Black Rectangular Steel Tube, features a precision-cut vertical opening along its length, allowing for adjustable hardware placement and easy integration into frames, railings, and support systems. The clean, black finish provides a modern, professional appearance while offering enhanced corrosion resistance. For designs needing a streamlined look with functional access, this Black Rectangular Pipe with Straight Opening is an ideal choice. Its design is perfect for architectural features, industrial furniture, and machinery guards where adjustability is key. We also offer this solution as a Black Rectangular Tube with Linear Cut, ensuring you find the precise component for your project's specifications and load-bearing requirements.


The Vertical Slotted Black Rectangular Hollow Tube distinguishes itself through a combination of robust material properties and meticulous manufacturing. Constructed from high-grade steel, each tube undergoes a forming and welding process to ensure consistent wall thickness and dimensional accuracy across its entire length. The vertical slot is then cleanly cut with laser or plasma technology, resulting in smooth edges that require minimal finishing. This tube is not merely a structural element; its hollow, slotted design is engineered for the internal routing of cables, wires, or small pneumatic lines, helping to organize and protect critical systems within a sleek enclosure. The durable black powder-coated or painted finish is applied after fabrication, creating a uniform layer that adheres tightly to the metal, providing long-lasting protection against scratches, moisture, and UV exposure. This makes the Vertical Slotted Black Rectangular Hollow Tube suitable for both indoor and outdoor installations where aesthetics and durability are equally important.
