Black Rectangular Tube with Linear Cut
For applications demanding both structural integrity and functional design, our Black Rectangular Tube with Linear Cut offers an exceptional solution. This component is engineered to provide a clean, linear aperture along its length, enabling easy access, attachment, or integration of other elements in assemblies. It is an ideal choice for framing, machine guards, enclosures, and modular support systems where a sleek, professional finish is required. If your specific project calls for a slightly different configuration, we offer several related products. You might consider the Black Rectangular Tube with Vertical Slot for oriented access points. Our Linear Slot Black Rectangular Steel Tube provides the same precision-cut functionality with a focus on material strength. For designs prioritizing a straightforward opening, the Black Rectangular Pipe with Straight Opening is available. Finally, the Vertical Slotted Black Rectangular Hollow Tube offers an alternative slot orientation for specific mounting needs.
The Black Rectangular Tube with Linear Cut is manufactured from high-quality, durable steel, ensuring long-term performance and resistance to deformation under load. The tube undergoes a precise cutting process to create a consistent, burr-free linear slot, followed by a uniform black oxide or powder-coated finish. This finish not only enhances the product's corrosion resistance but also provides a modern, matte black appearance suitable for both industrial and commercial aesthetics. The hollow rectangular profile offers an excellent strength-to-weight ratio, making it efficient for building robust structures without excessive bulk.

Key features and benefits include:
- Precision Machining: The linear cut is manufactured with high accuracy, ensuring consistent width and clean edges for smooth integration with bolts, panels, or slides.
- Enhanced Functionality: The slot allows for adjustable positioning of fixtures, mounting hardware, or wiring, adding versatility to the structural design.
- Durable Protection: The black finish acts as a protective layer against rust and wear, suitable for both indoor and protected outdoor environments.
- Structural Efficiency: The rectangular hollow section provides superior resistance to bending in both primary axes compared to solid bar or alternative shapes.
- Ease of Assembly: Pre-cut slot eliminates the need for secondary drilling or milling operations, saving time and labor during fabrication.
- Aesthetic Versatility: The clean lines and dark finish offer a professional look that integrates well into modern architectural and machine design.

Galvanized U-channel
Tianjin Xinlida Steel Pipe Co., Ltd. has long specialized in the manufacturing of steel pipes and structural steel, establishing a comprehensive business ecosystem that integrates domestic production, overseas bases, and global trade. Our galvanized U-channels offer a core competitive advantage by combining long-lasting corrosion resistance—achieved through hot-dip galvanizing that meets national standards—with a high-strength, one-piece formed structure. This solution effectively addresses four major industry pain points: structural corrosion, insufficient load-bearing capacity, lengthy construction periods, and high maintenance costs—challenges often encountered in coastal saline-alkali areas, humid mountainous regions, and environments subject to rain, snow, and low temperatures. We operate our own intelligent production facilities with substantial annual capacity and a full suite of advanced structural steel processing equipment. Adhering to the GB/T13912 galvanizing standard, we manufacture all U-channels using Q235B and Q355B grade steel, while offering services such as custom specifications, precision cutting, and prefabricated processing. Clients—whether for domestic projects or overseas trade—benefit from rapid production scheduling and flexible order adjustments; profile specifications and order quantities can be modified during production to meet project timelines and minimize inventory waste.
