Mild steel rectangle pipes are commonly used in construction, infrastructure, and manufacturing due to their strength, durability, and versatility. These pipes are typically made from mild steel, a type of carbon steel with low carbon content, making it more malleable and easier to work with compared to other types of steel.

Rectangle pipes are shaped like rectangular prisms, with four sides and two long parallel sides. They come in various dimensions to suit different applications and are often used for structural support, framework, fencing, and transportation of fluids or gases.

Mild steel rectangle pipes are favored for their affordability and suitability for welding, bending, and forming. They can be easily customized to meet specific project requirements and are available in different grades and thicknesses depending on the intended use and load-bearing capacity needed.
