A metal purlin is a lightweight, horizontal beam or bar that is used for structural support in roofing. In addition to providing support, metal purlins also increase a building's resistance to heavy winds. Purlins are a key component to the secondary frame of commercial, residential and industrial metal buildings.
Steel purlins are typically made from cold-formed steel. As opposed to working with hot metal, cold-formed steel is made by rolling and pressing thin sheets of steel into the desired shape. Cold-formed steel is stronger than hot-formed steel and easier to work with.
