LYSAGHT TOPSPAN® 120 is a 120mm deep profile used as a roof purlin or wall girt. It is commonly used in the rural, residential and small commercial market for shed, garages and awnings where longer spans or strength is required. It is commonly used in lieu of the smaller and lighter gauge traditional Cee and Zed purlins. It is commonly called a "rural purlin".
Its versatility has resulted in applications other than a purlin such as shelving and flooring.. Strong and rigid, LYSAGHT TOPSPAN® 120 is maintained even when lapped because the profile permits a precise, snug lap without the need to deform the section's shape.
