Flat steel refers to steel with a width of 12-300mm, thickness of 3-60mm, and a rectangular cross-section with slightly rounded edges. Flat steel can be a finished steel product or serve as billet for welded pipes and thin slab for hot-rolled thin plates.
Flat bar is primarily categorized into two types: equal-flange flat steel and unequal-flange flat steel. Equal-flange flat steel is also known as square steel. Flat steel specifications are denoted by the dimensions of its flange width and thickness.
Characteristics of Flat Steel
Currently, commonly used flat steel specifications range from 3mm*20m to 150mm, with corresponding steel grades. Beyond specification numbers, flat steel also features specific composition and performance series. Cold-drawn flat steel is delivered in fixed lengths or multiple lengths. The fixed length selection range varies from 3 to 9m depending on the specification number, allowing customers to choose based on actual needs.
Applications of Hot Rolled Flat Bar:
Application 1: Hot-rolled flat steel is suitable for fabricating structural components, staircases, bridges, and fencing. It offers excellent strength and features a smoother surface finish compared to other steel products. Additionally, its tightly spaced thickness specifications make it highly weldable. Notably, flat steel possesses substantial load-bearing capacity. Welding is an indispensable process in manufacturing structural components, staircases, and fences. These items also demand smooth steel surfaces capable of supporting heavy loads. Flat steel's characteristics perfectly meet these requirements, making it the raw material of choice for fabricating such structures.
Application 2: Hot-rolled flat steel can serve as billet material for welding or as slab for hot-rolled thin plates. As a steel product with a rectangular cross-section, it can be regarded as a segment of a long steel plate. This property enables hot-rolled flat steel to be processed into larger steel plates.
