In Japan, Japan before 1980 only the following production 200mmX200mm square rectangular tube and a small opening into a cold steel, the Japanese steel housing are used in the H section steel column. Sendai, Japan, earthquake o 1984, by Sendai forming machine earthquake damaged the steel structure housing study found that the forming machine welds between beams and columns easy to crack, because by the H shape steel structural characteristics of the restrictions, with steel and H H section steel welded cold roll forming, welding too little. Therefore, Japan in 1984 after the adoption of revised law, the provisions of Japan's steel structure residential square rectangular tube column must be used to increase the length of weld, thus improving the earthquake resistance house.

In the United States, noted in the survey data show that cold side and hot-rolled H section steel rectangular tube in the construction industry in the relationship between the amount of approximately 1:1, 90 in the 20th century, construction steel used in the proportion of cold-formed steel or cold Forming more than the amount of hot rolled H section steel. Among them, the cold junction pipe roll forming structure (including square rectangular tube pipe and the original) about the amount of construction Roll forming machine steel of 25% steel, all kinds of open steel cold-formed steel building steel consumption in the percentage of more than 20%. Domestic industry leader Kenuo Steel Cold Roll Forming long-director Mr. Qian Zhanxu also pointed out that: cold the next 5 years in China, will create tremendous impact steel construction.
