Concealed Cylinders Hydraulic Doors

Our patented concealed cylinder design tucks the lifting cylinders fully out of sight behind the door panel, so a closed door shows nothing but your chosen finish. When it opens, the motion becomes a kinetic architectural feature rather than visible hardware.

Concealed cylinder doors are built from 4'×4' up to 30' wide and 12' tall. Every door is fabricated to your exact opening on an all-welded steel frame — never cut down from a stock size — so the fit is exact.

Yes. We build the entire door, not just the hydraulics, so it can be finished in virtually any cladding material to match your siding, storefront, or interior. You choose the finish and we fabricate the door around it.

Yes. Concealed cylinder doors operate with no steps and no thresholds in the opening, which makes them well suited to homes, restaurants, and storefronts where accessible entry matters as much as the finished look.

Remote controls, custom switch gear, and high wind-load requirements are all integrated into the door during fabrication rather than added afterward. Tell us how you want to operate it and we engineer it in from the first drawing.

They’re built for spaces where the finished look matters as much as the function — homes, storefronts, restaurants, wineries, and architectural openings. For hangars, shops, and agricultural buildings at larger spans, exposed cylinder is usually the better fit.
