What Is Hollow Section Steel

Hollow structural section" is a term that is frequently abbreviated to "HSS" for convenience. It refers to a hollow-sectioned metal profile. This term is most likely heard in the United States or other countries with similar construction or engineering jargon. HSS members' cross-sections do not have to be circles, squares, or rectangles. They can be any of the remaining shapes. According to the code, HSS can only be made of structural steel.

People frequently confuse high-strength steel and hollow structural steel. If you want to buy hollow section steel Leeds contact GHE Sstansfeld UK Ltd. Square or rectangular HSS is also known as tube steel or box section. People frequently refer to circular HSS steel pipe by mistake, even though real steel pipe is measured and classified differently than HSS. This is because HSS occurs in cycles. The external dimensions of the profile are used to calculate the HSS dimensions.

Uses in Structures

Pipes are also manufactured to an external tolerance, but this tolerance is determined by a different standard. All of the HSS edges have been rounded to a radius about twice the thickness of the wall. The wall thickness is the same around the section.

Regarding construction and engineering, the term "HSS" is not used in the United Kingdom or any other country that follows the British terminology standard. These hollow sections are not known as CHS, SHS, or RHS. They are instead known as circular, square, and rectangular hollow sections. When constructors buy hollow section steel Leeds these are the same terms they use. These symbols depict various hollow section shapes, such as squares, rectangles, and circles. Because these designations frequently refer to metric sizes, the sizes and tolerances will differ slightly from HSS.

Their Best Choice

When members of a welded steel frame are loaded from different directions, HSS sections, particularly rectangular ones, are frequently used. Square and circular HSS are very good shapes for the multiple-axis loading used because their geometry is the same along two or more cross-sectional axes, and their strength is the same. They are good choices for columns because of these factors. They are also very strong and difficult to bend in any way.

Although HSS beams can be used, I-beams and wide flange beams are more common and often provide better structural efficiency when used for this purpose. Nonetheless, HSS is much more resistant to buckling than most other materials.

Conclusion

Engineers also buy hollow section steel Leeds sometimes to use them in exposed structures because of its flat, square surfaces because it looks better. However, for the same reasons as rectangular HSS, elliptical HSS is becoming more popular in exposed structures.
