We now have 37 manufacturing locations.
Welcome to our website from our founder, Jeff Knotts! We have been in the steel fabrication and irrigation pivot business at our shop near Felton, Delaware since 2000.
We specialize in building PowerLift hydraulic doors. With many PowerLift door installations across Delaware, Pennsylvania and Maryland our leadership in the door industry is clear. A PowerLift door is the best choice for your aviation, commercial, farm or architectural project.
Replace existing doors with a PowerLift hydraulic door and eliminate struggles with older sliding, bifold or overhead doors. We’ll be glad to stop and look at your existing building and suggest a simple PowerLift door solution.
Each PowerLift door is custom built in our own shop featuring all-welded construction and a precise fit. Once your door is complete we personally deliver and install it. You’ll appreciate the peace of mind this single source accountability provides.
We’re just a phone call away at every stage of your PowerLift door project including long after completion! We look forward to serving your door needs today and in the future.
