Sigma Non Composite

Sandwich Panel Connector

We have been changing the way industries think about structural fiberglass components. We don't enter any market unless there is a major advantage in the products we develop and ulimately sell. We have adapted our market leading technology in fiberglass rebar to make a sandwich panel connector pin that is stronger in every measure than the leading competiton. The Sigma Pin is made from an epoxy modified vinylester and E-CR glass for extreme durability and strength. The patent pending installation adapter makes installion of the pins an absolute breeze.


With center to center spacing as wide as 24", the quantity of pins is far fewer and labor savings even bigger when it comes to using the Sigma Pin for your next insulated wall panel project.
