A "metal flat bar" is a solid, rectangular strip of metal that is typically used in a variety of construction, fabrication, and manufacturing applications. The flat bar can be made from various types of metal, including aluminum, steel, and stainless steel, each offering different levels of strength, corrosion resistance, and weight. Aluminum flat bars, for example, are lightweight and resistant to rust, making them suitable for use in outdoor projects or areas exposed to moisture.

In the UK, suppliers like Aluminium Warehouse offer metal flat bars in various sizes and thicknesses, allowing customers to choose the right dimensions for their specific needs. These bars are often used in structural frameworks, support braces, brackets, and other applications where a strong, durable material is required
