Following picture shows the shuttering used for slabs.

This kind of steel shuttering is very useful as it reduces the plastering works. More over wooden logs are hard to remove and also cause breaking of edges. The steel shuttering when used with proper oiling is much easier to remove and also offers excellent finishing. All large projects use this kind of shuttering, only small house constructions are still using wooden planks and that too only in developing countries
