Concealed vs. Exposed Cylinder Hydraulic Doors: Which Is Right for You?

The Short Answer

PowerLift builds two kinds of hydraulic doors, and the right one comes down to looks and size. A concealed cylinder door hides its hydraulic cylinders when closed for a clean, architectural appearance — ideal for homes, storefronts, and design-forward spaces up to 30' wide. An exposed cylinder door mounts the cylinders in view — simple, serviceable, and proven — and handles the big stuff: aircraft hangars, shops, and commercial openings up to 130' wide and larger. Both are custom-fabricated on the same all-welded steel frame.

Here's how to decide.

The Core Difference: Where the Cylinders Live

• Concealed Cylinder: when the door is closed, the lifting cylinders are completely hidden. All you see is the door and its finish — no visible hardware. It's the choice when the door is part of the architecture.

• Exposed Cylinder: the cylinders are mounted in plain view. There's nothing wrong with that look — on a hangar or working shop it reads as purposeful and industrial — and it keeps the hardware simple and easy to service.

Both open the same way (a single panel lifting up and out on hydraulics); the difference is whether the mechanism shows.

Size and Scale

This is often the deciding factor:

• Concealed Cylinder ranges from small openings up to 30' wide by 12' tall. Great for residential and architectural openings.

• Exposed Cylinder goes from small up to 130' wide by 30' tall standard — and larger with specialized engineering. This is what you need for aircraft hangars and big commercial or agricultural spans.

If your opening is bigger than 30' wide, exposed cylinder is your door.

Best Applications for Each

Concealed Cylinder is ideal for:

• Homes — great rooms, kitchens, pool houses

• Storefronts, restaurants, and hospitality spaces

• Architectural openings where a clean, hardware-free look matters

• ADA-friendly, no-threshold openings

Exposed Cylinder is ideal for:

• Aircraft hangars

• Farm shops, equipment storage, and ag buildings

• Commercial and industrial buildings

• Large shops and car barns

What They Share

No matter which you choose, you get the PowerLift fundamentals:

• One single-unit, all-welded steel door — no bolts or screws to loosen.

• Custom-built to your exact opening and clad in glass, wood, steel, or virtually any material.

• Best-in-class weather seal and zero maintenance on most doors.

• Single-source accountability — we design, build, deliver, install, and support it, usually installing in a single day.

Quick Comparison

How to Choose in One Question

Ask yourself: "Is this door a design feature or a workhorse?"

• If the look is paramount and the opening is 30' or under → Concealed Cylinder.

• If you need scale, simplicity, and serviceability → Exposed Cylinder.

And if you're not sure, that's what we're here for — we'll look at your opening, your building, and how you'll use it, and recommend the right door.
