COMPOSITE REPAIR TECHNOLOGY
Fiber reinforced polymers (FRP) composites can dramatically increase a structure’s carrying capacity. FRP composite systems offer a low-cost, low-downtime, and low-weight solution for increasing the performance and lifetime value of structural steel while improving stability in seismic events.
Composites that Protect and Strengthen
Structural strengthening systems are made of high strength fibers such as glass, Kevlar, and carbon embedded in resin. The resin protects the fibers, maintains their alignment, and distributes the loads evenly among them. FRP’s, which have been widely used in industries such as aerospace, automotive, and sport equipment, are now becoming used extensively for the structural upgrade of steel and concrete structures.
Experts in the Field
Important characteristics of FRP’s for structural repair and strengthening applications are their non-corrosive properties, timeliness and ease of installation, low cost relative to demo and reconstruction. FRP materials can be adhered to beams and slabs to increase their shear and flexural capacity, and can be wrapped around columns to increase their load carrying capacity and ductility during seismic events.
FRP systems may also comprise of pre-manufactured strips and plates that are bonded to structural slabs, steel, deck, etc. using epoxy resin. Pre-cured FRP elements are more suited for flexural upgrade of columns, beams, and slabs. As with any other externally bonded system, the bond between the FRP system and the existing concrete is critical to achieve a composite behavior with the existing member. Accordingly, the most current National Association of Corrosion Engineers, and Society of Protective Coating Standards are used for proper surface preparation for ensuring a successful FRP structural upgrade.
SAFETY AND CERTIFICATIONS
Environmental, health, and safety are ingrained into our culture. At Coatings Unlimited, we firmly believe that no job is worth the life and wellbeing of any one of our team members or the community around us. For nearly seventy years, our team has worked diligently to create and sustain a culture of safety by taking a proactive approach to task-specific training, education, and responsibility. We believe safety is a responsibility we all share.
Compliance with industry certifications lowers the risk shouldered by facility owners when selecting a specialized contractor. We are proud to meet the Society for Protective Coatings requirements for QP-1, QP-2, QP-8, and QS-1 certifications, and more, meaning we are cleared to prepare surfaces, apply industrial coatings, as well as to remove and manage potentially hazardous materials
