What is cladding and how does it relate to roofing and walling?
Cladding is a collective term for any sheeting that covers a building, whether it be on the roof of the building, or on the walls. Roof cladding is made from thicker steel and is rolled to a profile capable of supporting roof loads e.g. live loads. In most cases, these roof claddings can also be used for walling as well. Wall cladding is made from thinner steel, rolled to a less rigid profile. They are generally not designed for live loads. Some roofing is designed to be non-trafficable (architectural roofs) ad in general, metal roofs are not meant for frequent or heavy foot traffic. Indian Standard (IS 875) limits live load on roofs to 75 kg per sq.m in general.
