Fiberglass Fabricators, Inc. specializes in fully designed, thoroughly engineered, low-profile composite cover systems. FRP covers are a cost-effective alternative to aluminum covers.

What is Fiberglass Reinforced Plastic (FRP)?
Fiberglass Reinforced Plastic is most often referred to simply as "fiberglass" in practice (as in fiberglass tanks, fiberglass grating, fiberglass structural shapes, etc.) Used in this context "fiberglass" is a composite consisting of a plastic resin matrix reinforced by embedded glass fibers. The strength of a fiberglass part is determined primarily by the type, orientation, quantity, and location of the glass fibers within the part.

What are the advantages to using FRP products in water and wastewater facilities?

  • Greater strength, pound for pound, than steel
  • Lightweight
  • Formability - Can be molded into complex, one piece designs
  • High impact resistance
  • High resistance to chemicals and corrosion due to the wastewater process
  • High resistance to heat and extreme cold
    (Unaffected by frequent temperature variations)
  • Attractive - molded in colors
  • Exceptional uniformity, dimensional accuracy and stability
  • Easy to clean surface
  • Low maintenance/down time
  • Easy to install - structural members are all cut to length and match-marked
  • Cost effective

What does FFI mean when they say all Fiberglass is NOT created equal?
All Fiberglass laminates manufactured by FFI are engineered based upon directional loading conditions and the chemical environment.

By which standard does FFI build their covers?
FFI produces the most technologically sound and durable advanced composite components that meet or exceed ASCE standards.

What kind of loading can a flat cover handle?
The covers are designed to be fully walk-able and to handle all environmental loading conditions based on ASCE standards with a maximum deflection limit of L/360.

What is Pultrusion?
Pultrusion is a manufacturing process for producing continuous lengths of reinforced plastic structural shapes. Raw materials are a liquid resin mixture (containing resin, fillers and specialized additives) and flexible textile reinforcing fibers. The process involves pulling these raw materials (rather than pushing as in the process of extrusion) through a heated steel forming die using a continuous pulling device. The reinforcement materials are in continuous forms such as rolls of fiberglass mat or doffs of fiberglass roving. As the reinforcements are saturated with the resin mixture ("wet-out") in the resin bath and pulled through the die, the gelation (or hardening) of the resin is initiated by the heat from the die and a rigid, cured profile is formed that corresponds to the shape of the die.

While pultrusion machine design varies with part geometry, the basic pultrusion process concept is described in the following schematic.
