Steel-framed houses are still a new thing for Chinese people who are used to reinforced concrete.

The steel structure residential system was developed on the basis of wooden structure houses in foreign countries, especially in North America. Although these two systems are very mature and perfect in foreign countries, they are completely new things for China, so the difficulties are almost everywhere.

"First, in terms of building materials and parts, many of the materials needed for the construction of steel structure test projects are shipped from abroad. Some parts that are commissioned by foreign companies in mainland China often can only be purchased abroad. The market has not been found for a while."

"Secondly, in terms of personnel, since there is less content involved in the steel structure housing system in the teaching content of medium or high-level professional schools in China, and the lack of skilled workers, even this system is purely There is not much difficulty on the technical level, but the real implementation often lacks a capable backbone."

"Thirdly, in terms of building management, China's current building management model and steel-structured housing are not suitable for industrial production. After China's accession to the WTO, many foreign housing manufacturers hope to enter the Chinese mainland market, but they can't figure out their own. What qualifications should I apply for when I come to China? What is the identity – design unit, construction unit, integrator or manufacturer?” Zhang Yancai said.

Du Zonghan, president of the China Building Metal Structure Association, holds the same view. He said: "Chinese consumers have long been accustomed to brick-and-mortar or reinforced concrete structures, and they have gradually begun to accept the gradual preference for light-steel houses, and a gradual process is needed."
