the advantage and disadvantage of cold formed steel?
Answers
Answer:
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.
The advantages of
cold formed steel sections are:
Cold-formed steel features superior chemical and physical qualities that give it a broad range of advantages over other framing materials.
Strength. Steel has the highest strength-- to-- weight ratio of any building material. Moreover, the strength of cold-formed steel also provides architects with greater flexibility, allowing designs that incorporate longer spans and other architectural features.
Durability. Steel is inorganic, and thus impervious to termites, rot and mold. A protective layer of zinc and other metallic coating steel provides long-term durability that research demonstrates can last hundreds of years without any deterioration.
Advantages of cold-formed steel is given below:
• The main application of cold-formed steel is it can be molded into a huge variety of shapes.
• Cold-formed steel is widely used in automobiles and manufacturing of appliances.
• Cold-formed steel is very strong and it's durability also long-lasting.
• Cold-formed steel making is very cheaper than lumber alternatives.
Disadvantages of cold-formed steel is given below:
• Cold-formed steel has a low fire resistance and the Unit of steel price also very high.
• Residual stress will affect the buckling resistance of the steel.
• Cold-formed steel is not easy to connect and they have to be built very carefully.
