Simpson Strong-Tie Composite Strengthening Systems™ are designed, tested and manufactured to offer high-performance solutions and lasting results. Simpson Strong-Tie Composite Strengthening Systems (CSS) provide efficient fiber reinforced polymer (FRP) solutions for the structural reinforcement and strengthening of concrete, masonry and timber structures in need of repair or upgrade. The primary benefit of FRP systems versus traditional retrofit methods is that significant flexural, axial or shear strength gains can be realized with an easy-to-apply composite that does not add significant weight or mass to the structure. Steel plate bonding, concrete section enlargement and steel jacketing have been the renovation methods of choice for decades, yet corrosion, bond degradation and installation difficulty are consistent challenges to overcome, and the resultant retrofit generally adds weight, reduces usable space, clearance, or both. In many cases, FRP is the most economical choice given the reduced preparation and labor costs. FRP can usually be installed without taking the structure out of service.
