General Rubber acquired by CECO

Adds industrial flow control Leader, nearly doubles addressable market size

“You need to buy these things, guys. It’s going to save you money in the end.”
Mike Zirpolo
Principal Port Engineer, USNS Port Cesar Chavez


Proven Experience

Our FRP composite louvers are utilized aboard both LPD San Antonio-class ships and T-AKE class ships, such as the USNS Cesar Chavez. Louvers on the former use a tongue-and-groove assembly technique so they can be mounted into bulkhead openings with radiused corners. Louvers aboard the latter utilize less expensive, square-corner frames as these are mounted flush behind an opening in the hull.

On June 19, CECO Peerless had an opportunity to present a technical paper on corrosion within marine environments to a highly distinguished group of peers and naval engineers at the 2019 ASNE Conference in Washington, DC. This paper was chosen out of hundreds of entries and illustrates our body of work with the US Navy, the business impact of applying FRP composites aboard ship and recommendations for the future.
