RS TENSILE PVT IN DELHI When the material is under tension, it is known as tensile. The forces that are acting along the axis of force are responsible for the stretching of the material. The external force per unit area of the material resulting in the stretch of the material is known as tensile stress. Tensile testing helps ensure that a weld meets the required levels of strength and ductility. Filler metal manufacturers perform tensile testing on many of their products for several reasons. Like many end users, they may perform tensile testing to help monitor process quality. A tensile membrane structure is most often used as a roof, as they can economically and attractively span large distances. Tensile membrane structures may also be used as complete buildings, with a few common applications being sports facilities, warehousing and storage buildings, and exhibition venues.
