Straight Open Black Rectangular Steel Pipe
Introduction to the Straight Open Black Rectangular Steel Pipe
For projects demanding clean lines, structural integrity, and a modern aesthetic, the Straight Open Black Rectangular Steel Pipe is an exceptional choice. This versatile structural component is engineered for precision, offering a robust and visually striking solution for a wide range of applications. Its defining feature is the straight, open channel, designed to facilitate easy integration with mounting hardware, cables, or other structural elements. This design is particularly beneficial in architectural frameworks, industrial shelving, and custom fabrication where both strength and accessibility are paramount. Our commitment to quality ensures each pipe is fabricated from high-grade steel, finished with a durable black coating that provides corrosion resistance and a sleek, professional appearance. When your specifications call for specialized variations, we also offer a comprehensive selection of related profiles, including the Black Rectangular Tube with Vertical Slot for vertical mounting systems, the Linear Slot Black Rectangular Steel Tube for adjustable fixtures, the Black Rectangular Pipe with Straight Opening for similar open-channel needs, and the Vertical Slotted Black Rectangular Hollow Tube designed for specific directional fastening requirements.
Detailed Specifications and Material Properties
To ensure the Straight Open Black Rectangular Steel Pipe meets the rigorous demands of professional use, it is manufactured to exacting standards. The primary material is ASTM A500 Grade B or equivalent structural steel, known for its excellent strength-to-weight ratio and weldability. The standard finish is a powder-coated black epoxy layer, which offers superior protection against rust, scratches, and UV degradation compared to standard paint. Below are the key technical parameters available from stock, with custom sizes available upon request.

The manufacturing process for the Straight Open Black Rectangular Steel Pipe involves precise cold-forming of the steel coil into a rectangular hollow section, followed by high-frequency welding to create a consistent, strong seam. The open section is then milled or saw-cut to ensure clean, burr-free edges. Finally, the pipe undergoes a multi-stage pre-treatment (cleaning, phosphating) before the electrostatic application and thermal curing of the powder coat, resulting in a uniform, durable finish. The open design not only reduces overall weight but also allows for internal routing of utilities or the insertion of complementary components, adding to its functional versatility in complex assemblies.
