Steel door hardware is generally installed on site, while steel wood doors are normally assembled with frame leaves, reducing on-site installation costs. Steel frame fixing is faster and more convenient than that of wooden frame.

In addition, in the basement and the coastal area, the steel frame avoids the disadvantages of the wooden frame being easy to absorb water and deform.
