Cold Formed Rectangular Hollow Sections are widely utilized as structural components due to their excellent strength and weldability. These sections are available in sizes ranging from 10 x 15 mm to 800 x 1200 mm, with thicknesses varying from 0.5 mm to 60 mm for larger sections.
The Cold Formed EN10219 Black Rectangular Hollow Section adheres to the EN 10219 standard and is frequently employed in construction and engineering applications. It is ideal for creating robust, lightweight structures such as bridges, buildings, and machinery. The design of the hollow section promotes efficient material use, making it both cost-effective and environmentally sustainable.
Advantages of Cold Formed Rectangular Hollow Section
- High Strength:
The cold forming process occurs at room temperature, preserving the material's grain structure, which results in enhanced tensile and yield strength.
- Outstanding Mechanical Performance:
These sections feature smooth surfaces, precise dimensions, and exceptional mechanical properties.
- Corrosion Resistance:
With surface treatments such as galvanizing or coating, cold formed rectangular hollow sections exhibit strong corrosion resistance, prolonging the lifespan of structures.
- Ease of Processing:
They possess excellent processing capabilities, allowing for straightforward cutting, welding, and other fabrication processes.
