Gang Forms: Tru-beam Forms

Tru-beam Gang Forms

Tru-beam gangs have been used on a variety of projects such as deep foundations, high-rise buildings, tunnels, shafts, retaining walls, sewage treatment plants, reservoir, water treatment plants, and many others.


The basic components of this system are 3/4" plywood attached to    2 1/4" x 7 1/4" laminated wood beams. Backing these beams with 8" double steel channel wales.


The advantage of the wide tie spacing is the reduction in labor to set and strip custom built Tru-beam gangs. Studies have shown that as much as 38% of the cost of a concrete structure is related to form labor, with almost 40% of form labor to handle, set, strip, and patch ties.


Specifically designed channel wales can be fabricated for walls with haunches at the top or bottom to accommodate a variety of shapes.


Various types of plywood, M.D.O., H.D.O., or phenolic coated birch, are available, depending on the number of uses and the concrete finish required.

Curved Forms

Forming Concept's curved forms use vertical Tru-beams backed with double steel channel wales and the radius is formed using wood packing wales. If a project has wall heights that are fairly close but different radii, the packing wales can be changed to accommodate them.


Forms are delivered in widths from 8' to 12'. Gangs are delivered to the jobsite pre-assembled to your required radius, unloaded from a truck, and set in place with a crane.


All in all, the Tru-beam gang form system is one of the most cost efficient systems available today.
