WOOD
Often unique
shapes are required to be formed in concrete that cannot be
formed using standard modular sized forms. In this case a
form can be designed using wood. These can either be braced
internally or used with thru-ties.

Steel
Odd shapes that
require high reuse are often formed using steel forms that
can be hinged for easy removal.
