Hot-rolled rigid frames are a specialized system of steel beams and columns fastened together with tight connections that help maintain the integrity of the structure. This is a unitized construction and therefore, bracing is not necessary. Many single story buildings are made with this approach. So what is the advantage of the hot-rolled rigid frame? Well, it has a more efficient use of steel and cleaning and maintenance are easier (compared to truss construction). Also, it does a better job supporting heavier loads. The hot-rolled wide flange beam approach is, in addition, very common. There can be virtually unlimited choices to shape or size configurations with the utilization of these specific beams. A wide array of pitches and loads can be effortlessly adjusted using this approach.
