Question

Disadvantages of cold formed steel sections

Answer 1

Cold-formed steel refers to the products which are made by rolling or pressing steel into finished or semi-finished goods are relatively low temperatures.

The disadvantages of cold formed steel sections are:

1. Unit price is high.

2. It is difficult to connect them.

3. They have low fire resistance.

4. They have to be assembled very carefully.

5. There is residual stress on the cross-section this affects the buckling resistance of the steel.

6. It is prone to reverse when there is flexural compression.

7. It has less ability to withstand localized concentrated load.
