There are numerous fabricators through out the country that can supply FRP (fiberglass reinforced plastic) corrosion resistant ductwork but a select few that can supply the level of quality and service Belco provides to each and every customer regardless of scope or size.

Belco can manufacture any size or shape FRP Duct, fitting or accessory that your process may require.  All of our equipment is manufactured in house, giving us the ability to construct special fitting shapes, sizes, transitions etc.  Our capabilities are limited only by your imagination.

All of our duct is manufactured to meet or exceed the Voluntary Product Standard PS 15-69, ASTM 3982 "Standard Specification for Contact Molded Fiberglass Duct and Hoods", and AWWA M-45 when FRP ductwork is used in buried applications including design for H-20 axial loading.  

We have provided a Sample Specification that would typically be followed during the Manufacturing and Installation process. This specification is written so that all industry standard design criteria and manufacturing procedures are followed whether or not Belco is the supplier of choice.
