Prisma composite stringers are manufactured and constructed from high quality fiberglass knit fabrics and 2 pcf flotation grade polyurethane foam by a patented process. These preforms stringers feature a built-in dead rise converters (DRC).
Common installations usually only require a simple, three-step process. Wet out the underside of each Prisma beam, position them where desired, wet out the top side of each beam, roll the tabs, and you're done. Prisma preforms saves time, material, and labor costs on just about every installation.
Sold in 4ft lengths.
