FRP Components

Fiber Reinforced Polymer Components

Over the past thirty years FRP (Fiber Reinforced Polymer) components – pultrusions, filament-wound piping and vessels, and hand-layup molded shapes such as fan stacks and casing panels – have become the go-to materials for structures of all types in many construction industries.

FRP Component Applications

Cooling towers, water treatment plants, aquariums, biofiltration systems, and more rely on FRP products to provide the strength and non-corrosive features that FRP products offer over similar steel structures.

Great Customer Service

“L S Enterprise LLC is an excellent source for Brentwood parts. They have extensive knowledge of cooling towers, and they make sure they are quoting what I actually need and not blindly quote what I ask for. They have caught my measurement errors on more than one occasion saving me from misquoting jobs and being short on parts at a job. Great customer service. ”
