Taper Ties Data Sheet
Taper Ties
High-capacity, reusable, gangform tie that spreads the
tie spacing and reduces the number of ties
Taper Ties are used in forming situations where the ties are
completely removed from the concrete after the pour has
cured. Commonly used with gangform systems, Taper Ties
enable contractors to efficiently assemble and strip formwork.
Applying waterproof grease evenly on each Taper Tie prior to
concrete placement facilitates removal.
Taper Ties are squared-off at each end, allowing the tie to be
turned with a wrench during the removal process. The tie can
also be struck on the squared-off end of the smaller side with a
hammer for removal from the gangform and wall.
High-capacity Taper Ties reduce the
number of ties needed for gangforming.
