Totally Encapsulated Support System, a patented process in which the tread blocks and dead end blocks are moulded into the step at time of forming, using no glue or mechanical fasteners. The step encapsulates the supports resulting in a system superior to that of the competition.   Click on the side view picture to enlarge. Molded-in dead-end block allows for water-tight, screw installation. Raised, non-slip tread pattern allows for safe and easy pool entry and exit. Performance Steps are molded from a solid sheet of coextruded Luran® S with an ABS substrate from BASF resulting in a strong, one-piece design, that will never delaminate, splinter, corrode or puncture. The high-impact strength and flexibility of weatherable polymers enables Performance Steps to withstand the stress of frost and back fill saturation far better than other materials. One-piece molded thermoplastic grid system supports the entire tread surface and prevents material fatigue. Modular bracing allows for optional deck support. A stylish cantilever edge for poured concrete decking is created with optional styrofoam forms. Extruded aluminum coping provides an attractive border for poured concrete decking
