Concrete Inserts for Strength and Permanence

Unistrut Concrete Inserts

Unistrut Concrete InsertsConcrete Inserts Create a Permanent Steel Framework of Support

Concrete Inserts are used in concrete poured walls, floors, ceilings, foundations and pre-cast culverts. Unistrut concrete inserts offer a fully-engineered solution, integrating steel channel and parts, to create a cast-in-place concrete framework. This framework provides superior strength and durability to your system.


concrete insertsUnistrut Concrete Inserts are mounted into place prior to pouring concrete. The steel framework is cemented into place, as the concrete hardens, thus providing a permanent solution.

Inserts are firmly attached to the concrete side of the form prior to pouring. When the forms are removed, the insert is ready for use. Brackets and other components are now ready to connect to the embedded steel frameworks to create light structural support.

Standard duty inserts support such things as raceway, conduit, water lines, gas lines and other light weight systems. Whereas heavy duty inserts support systems of five thousand pounds or more, as in the case of anchoring curtain wall.
