Prefabricated Curbs

Economical and Convenient Alternative to Site Built Curbs

Wasco’s prefabricated curbs are fully welded and assembled to reduce installation time and cost, with no chance of missing parts and no field assembly. Available in insulated and non-insulated models as structural or non-structural.

Choose the optional 14 gauge steel to eliminate the need for costly structural reinforcement by eliminating the need for structural steel sub frames when mounted to the steel joists of the building prior to deck installation.

Curbs come standard with an impact tested security screen. The screens are fabricated in a 6″ x 6″ welded grid pattern using 3/16″ cold-rolled galvanized steel rod.
