Flangeforms are installed
by lapping 2', 3' and 4' segments over one another
to create a void length specified by the design engineer.
While they are capable of providing the structural
profile
required, the lapping of the forms creates offsets
that create a class "D" finish (up to 1" offsets)
If the finish required is better than a class "D",
then some other type of form should be specified. |
