Ryterna Rib Garage Door Ryterna Steel Sectional Doors

Ryterna Rib Sectional Garage Door

The Ryterna Rib is a timeless, versatile choice that looks right at home on almost any UK property, from modern new builds to traditional semis. The horizontal ribbed pattern adds just enough detail to break up the surface, ensuring the door doesn't look plain or "blocky," especially on wider double garages.

Practicality is a huge plus here. The door is built from 40 mm thick insulated steel panels, which acts as a thermal barrier to keep the cold out. If your garage is attached to your house, or if you use the space for a gym or workshop, this insulation—combined with proper weather seals—makes a massive difference compared to an old, draughty up-and-over door.

You can order the Rib design in a durable stucco texture or a smooth woodgrain finish, and there are endless colour options. While Traffic White and Anthracite Grey are the go-to favourites for a modern look, you can match virtually any paint colour. Because every door is made to measure, you can also add windows or choose a matching side door to really tidy up the front of your home.

Why choose this Ryterna model?

While most manufacturers treat ribbed doors as a "budget" standard product with limited sizes, Ryterna manufactures every Rib door to the exact millimetre. This ensures a perfect fit for your opening without expensive "non-standard" surcharges. Crucially, you can also specify a matching Ryterna aluminium front entrance door (RD80/RD100) using the exact same ribbed panel and colour batch, guaranteeing a perfectly coordinated "grand entrance" look that's nearly impossible to achieve when buying from separate suppliers.
