Ryterna Midrib Garage Door Ryterna Steel Sectional Doors

Ryterna Midrib Sectional Garage Door

If you want the classic look of timber planks but don't want the hassle of sanding and varnishing, the Ryterna Midrib is a brilliant solution. The panel has a groove running through the centre, creating a "two-board" effect that gives the door more character. It sits really well on homes with cladding, brickwork, or cottage-style features.

The Midrib is available in some impressive wood-effect finishes—like Golden Oak, Rosewood, and Winchester—which give you the visual warmth of real wood but with the durability of steel. It means your garage door looks great year after year with just a quick wipe-down, rather than needing annual maintenance.

Underneath the surface, you get the full benefits of a modern sectional door: 40 mm insulation to keep the warmth in, finger-safe panels for safety, and heavy-duty rubber seals to keep the British weather at bay. It's a smart upgrade that improves both the look and the comfort of your home.

Why choose this Ryterna model?

The Midrib is the ultimate "problem solver" for renovation projects. Ryterna's flexible production allows you to order this design in bespoke sizes and colours—including realistic wood-effects like Winchester and Golden Oak—that perfectly match your existing windows. Unlike competitors who only offer standard sizes, Ryterna allows you to pair this garage door with a matching side or front door, ensuring the groove lines align precisely across your home's exterior for a truly cohesive look.
