The steel frame method uses a combination of pillars and beams of steel
This includes the “ramen” construction method, which is joined by welding junctions of the main structure, as well as the bracing method, which achieves reinforcement using braces
There is also the method known as “S-ALC construction,” which utilizes lightweight foam panels in a steel framework
All these methods boast higher strength than wooden construction methods, as well as offering superior earthquake resistance.
Furthermore, because of its light weight compared to reinforced concrete, steel can be utilized for longer beams and wider pillars. This cuts down on the required number of beams and pillars, making any future renovations easier.
Steel does have some weaknesses. It is susceptible to heat, and because it is a ferrous material, rusting may occur, which degrades its strength. If proper anti-corrosion treatment, insulation work, and anti-fire treatment are carried out, steel construction can offer comfortable and continuous use.
