What our clients say
We could not have accomplished the growth that we have had in the last ten years without PennFab’s dedication to Quality, Competitiveness and all around customer satisfaction.
Frankly, you are one of the few companies that really do care about what you do and it shows in your every action. I wish you could handle every fabrication job we do.
The degree of professionalism and level of quality is second to none
Mike Mabin and his employees at PennFab represent what a company can achieve when they continually set the bar higher. You are no doubt one of the finest companies in our County and I am proud to deliver this Proclamation naming July 28, 2003 PennFab, Inc. day, on this your 20th Anniversary.
I so much respect the bedrock of your philosophy—hard work, smart work and an uncompromising sense of doing the right thing. ‘It is in giving that we receive’, says Saint Francis. If he is as dead on as I think he is, than PennFab’s destiny is a rosy one.
Every time I’m in this plant and see the level of Quality and Pride your company has it aggravates me to no end that we can’t just give you every job we have to fabricate.
You guys are the Best! Period. Without exception. No one does what you do.
PennFab is a World Class fabrication company and without their help we could not have obtained the level of expertise and craftsmanship that we did.
We could not have accomplished the growth that we have had in the last ten years without PennFab’s dedication to Quality, Competitiveness and all around customer satisfaction.
