Scope of Application
Home appliances
Steel is used in hundreds of appliances in the home. Fridges, freezers, microwaves, extractor hoods and washing machines all use mild steel. The metal is given layers of coatings and its surface is treated to make the products safe, reliable and long-lasting. It also helps protect against wear and tear, and corrosion. Flat steel bars are also used in garage doors, latches and heaters, as well as many other elements of residential construction.
Building frames
Steel flat bars have a major role to play in frame construction. The parts can be pre-fabricated in the factory, while girders and angles can be bought ready-made, saving time spent building. Steel flat bars function in the same way as hollow steel sections or may be used in many different types of building installations together with hollow steel bars. Steel flat bars are so versatile that they can be made to take any shape and clad with any materials.
Structures within the energy industry
For decades, steel beams and bars have provided the infrastructure for everything from refineries to pressure valves, and are going to come into play more than ever before with renewable energy infrastructure too. They are also used as the foundation in water tower structures and as concrete-reinforcing bars for foundations in water gates, generators and turbines.
Ornamental/artistic pieces
Flat steel bars are so malleable and workable that they lend themselves to endless forms of art, decor and industrial art pieces. From sculptures to modern shelving units, well-chosen steel flat bars can be used in just about anything. Steel sections that go through additional manufacturing processes are given a smoother finish and outer layering, giving pieces of art a cleaner, sharper appearance as well as a more reflective surface. Stunning works of art can also be made from scrap steel bars.
