The Dominator Sierra is a premium modern minimalist steel sectional garage door folded from heavy gauge steel to produce a strikingly flat entry point to your garage and home.

The superior flat folded design creates a truly flat finish that is solid and strong making this an excellent choice for modern home designs.


A visually crisp door choice with fine horizontal lines that complement most modern cladding designs. The Sierra is available in Zincalume™ or powder coated from a vast range of popular Dulux® Powder Coating colours.

This door style can also be fully insulated to help regulate the internal garage temperature and reduce sound transmission into and out of the garage.

Designed to be operated with an automatic garage door opener, we recommend our Dominator range of openers with either the Chain or Belt-drive configuration for the ultimate door and opener package.

Manufactured by roll-forming 0.75 BMT steel, the Sierra provides an appealing crisp focal point to the front of your home.

Whether you are upgrading your existing door or require a new one, Dominator’s new insulated series can help make the space behind your new Dominator Insulated Garage Door and Opener much more comfortable.

Temperature & Noise Control

With insulation your door becomes an excellent barrier to noise pollution. The acoustic qualities of our Insulated Series provide the perfect shield against noise entering and/or exiting your garage – great for busy roads or budding musicians! Our new Insulated Series garage doors help regulate the temperature and noise in your garage so you can use it the way you want to.

Ability To Choose

We know every home is different and every garage is used differently, we have created our Insulated Series to give you the choice should you wish to insulate your new Dominator Sectional Door.

Free Up Garage Space

We’ve taken our most popular styles of sectional doors and added a sophisticated insulator used the world over. Silver-grey in colour, this unique product is EPS infused with graphite to further absorb infrared energy and reflect heat providing around 20% better insulating performance than standard EPS. A remarkable product matched to a premium brand.

A More Distinguished Look

The Mulflute backing that houses our precision-cut insulation is a carbon-grey finish that adds a distinguished look to the internal face of the door. Low maintenance yet replaceable. All this with the same quality hardware, styles and finish on the front of the door that people around New Zealand have come to know and expect from the trusted brand of Dom.


As the largest door in the home, the garage door plays an important role in protecting what’s valuable to you.

We recommend all our Sectional Doors are fitted with an Automatic Opener from the Dominator range. The Opener is geared so that the door cannot be pushed or pulled open from the outside.


In response to a growing demand for extra security and convenience, we have released the Dominator Auto-Lock.

This smart keyless device will slide a bolt into the guide track automatically when the door is closed. This means the Auto-Lock does not require any additional action from you to operate. The lock more than doubles the force required at the lock point to lift the door from a closed position, helping protect your home and loved ones.

Emergency External Key Lock

If there are no other access points into the garage, an external key lock is recommended as optional extra. This will allow you to gain access into the garage in case there is a power cut.

Installation Clearances

Recommended Clearance Requirements:

  • Standard Headroom – 300mm
  • Standard Headroom with opener – 300mm
  • Low Headroom with opener – 200mm (Opener Recommended)
