![]() Steel and metal building constructionModern steel buildings are built using a portal frame structure with the frames co-ordinated into the form of bays. In use, the frame bears the weight of the building and walls. And for bigger buildings, more bays are used to spread the design to the available space. The beams that build up the frame allows the weight of the building to be held without needing supporting walls or interior columns. This frame structure provides for a huge amount of flexibility in design and allows for many types of walling or cladding and doors and windows.. | ![]() Materials and optionsThe basic steel frame of your steel building can be used with different wall coverings, doors, windows depending on use.
