What are the advantages of steel hollow section in relation to the open sections?

BS EN 10219-1:2006

Cold formed hollow sections for steel construction ensure high mechanical resistance and high yield strength. They are used as a fixed load-bearing structures in the building and civil engineering, are suitable elements in mechanical engineering because of its static advantages, and are also used in aerospace and automotive industry. They are not suitable for dynamic loads. They are produced at room temperature, by cold forming the sheet which is longitudinally welded at the ends, and therefore also known as welded hollow sections.

At the request and the technical possibilities, the inner weld can be removed or smoothed, while the outer weld is already processed in most cases. Due to the process of cold forming, there is a high level of residual stress remaining in the hollow sections which the can cause cracks during workload.

Unlike warm-formed hollow sections, cold-formed have considerably greater accuracy of wall thickness, and they are visually more attractive thanks to the flat and smooth surface. Cold formed hollow sections are defined by the European standard EN The greatest advantage of cold formed hollow sections is the way they are made that enables the production of round, square or rectangular pipes from almost any material at an affordable price.

There are uniform names prescribed to facilitate the administrative work with these or other types of hollow sections, so that everyone would know which product it is when seeing the specification.

According to EN the following denotements are defined: Common materials of which cold-formed hollow sections are made according to EN The square hollow section of total produced lenght of It was measured that the flatness deviation is 16 mm.

Tolerated deviation on the length of 12, mm is Measurement can be made on a meter in length from an arbitrary starting point, and find out that at one point deviation is 3. No matter that the total length of the deviation is within the limits, more precise measurements determined impermissible deviation, and the product can be declared as defective and to be reclaimed.

Round tube in a fixed length of 3. The tolerance on the total lenght is not considered in this case which is beyond the allowed limitsbut the deviation is measured for every meter away from any arbitrary point. All measurements have shown that the deviation from flatness is within the allowed 3 mm per meter of length.

Therefore, the product is correct though not flat. Learn more I understand. Cold formed welded hollow sections according to EN Related items What are hollow sections according EN ?
