EN10219 carbon steel cold formed rectangular hollow section
Cold-formed rectangular hollow sections have become a staple in the construction industry due to their superior strength and versatility. These sections are manufactured in a variety of sizes, ranging from small dimensions like 10 x 15 mm up to large profiles measuring 800 x 1200 mm, with wall thicknesses that can vary between 0.5 mm and 60 mm depending on the size. This adaptability makes them suitable for an extensive range of applications.
The Cold Formed EN10219 Black Rectangular Hollow Section complies with the European standard EN 10219 and is commonly used in both civil and industrial projects. Its robust yet lightweight design is perfect for constructing durable frameworks in buildings, bridges, and machinery. By optimizing material usage, these sections offer not only economic benefits but also contribute to environmental sustainability.
One of the key advantages of using cold-formed rectangular hollow sections lies in their high strength-to-weight ratio. The cold-forming process preserves the integrity of the steel’s grain structure, resulting in increased tensile and yield strength compared to hot-rolled alternatives. Additionally, these sections boast excellent mechanical performance, featuring smooth surfaces, precise dimensions, and reliable load-bearing capabilities.
Another significant benefit is their inherent corrosion resistance when treated with coatings or galvanization. This protective layer enhances longevity, making these sections ideal for environments where durability is paramount. Moreover, they are easy to fabricate, allowing for seamless cutting, welding, and assembly during construction phases.
For those interested in specific dimensions, here is a glimpse into the wide array of options available:
| Outer Dimension (mm) | Wall Thickness (mm) |
|-----------------------|--------------------|
| 20x20 | 1.3 |
| | 1.4 |
| | 1.5 |
| | 1.7 |
| | 1.8 |
| | 2.0 |
The applications span across multiple sectors, from structural support in residential and commercial buildings to critical elements in transportation infrastructure like bridges. They are also integral parts of manufacturing equipment and heavy-duty machinery. Whether you need a sturdy column for a skyscraper or a resilient pier for a bridge, cold-formed rectangular hollow sections provide the reliability and efficiency required for modern engineering challenges.
