A metal frame is a structure made from metal, typically consisting of a series of connected bars or beams that form a rigid framework. This type of construction can be used for various purposes such as building frames, furniture, and other structures where strength and durability are important factors. The term "metal frame" generally refers to any object or structure made from metal materials like steel, aluminum, or iron, which provide support and stability through their rigidity and resistance to bending or deformation.
