Safety & Quality

When you’re responsible for handling heavy machinery and producing large structures, there is no question that safety must sit at the top of your priorities list. At PennFab, we take safety incredibly seriously. This applies not just to those working at our facilities, but anyone who may come in contact with one of our finished structures out in the world. We ensure nothing short of certainty when it comes to the safety of our products.  We have an in-house certified weld inspector (CWI) and utilize third-party non-destructive testing (NDT) to ensure welds meet required specifications.

While other fabricators and manufacturers look to cut corners to increase efficiency, and reduce costs, PennFab upholds rigorous record keeping and strict adherence to customer specifications without sacrificing the quality of our work.
