Steel frame is a building method with a framework of standing steel columns and parallel I-beams, built in a rectangular grid to hold up the floors, roof and walls of a structure which are all fixed to the frame.
The process is carried out in such a way that the rolled steel or cross sections of steel columns are shaped in a form of letter "I". There are two flanges of a column which are thick and wide than the flanges situated on a beam to which gives a better hold up compressive pressure in the structure. Usually square and round tubular segments of steel are used which are often filled with concrete and cement. Steel beams are fitted to the columns with bolts and threaded clasps.
These are also connected by rivets. Frame of the Steel Frame Buildings or the steel framed house is covered by wide sheets of steel deck. It forms asolid layer of concrete and steel reinforcing bar. One moreacceptedoption is a floor of precast concrete floor covering units with some type of concrete topping. Frequently in office buildings, the floor surface is provided by some type of raised floor covering system with the void between the walking surface and the structural flooring being used for cables and air handling tubes.
The steel frame needs to be secured from fire, since steel starts to get soften at high temperature. This can cause the structure to fall down. The beams may be fitted under concrete, plasterboard or sprayed with a covering to pad it from the heat of the fire or it can be secured by a fire resistant ceiling edifice. Asbestos was an admired material for fireproofing the steel structure, until the near the beginningof 1970s, before the health risks of asbestos fibers were completely understood.
