Steel frame

Steel frame is like a super strong skeleton made out of metal that holds up buildings and other structures. Just like your bones hold your body up, a steel frame holds up a building. The steel used in frames is made from iron and other metals that are melted together and poured into molds to make big metal beams, columns, and other shapes. These pieces are then welded or bolted together to make a strong frame that can bear a lot of weight and resist strong winds and earthquakes. Steel frames are popular because they are durable, long-lasting and require less maintenance than other materials, like wood or concrete. Plus, they can be formed into many different shapes and sizes, allowing architects and engineers to create buildings that are beautiful, safe, and efficient.
