Dominator Sierra

The Dominator SierraTM 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.

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

Have you thought about insulating your new garage door?!

It’s been another season of weather extremes and while we can’t do much about the climate outside we can help make the space behind your new Dominator Insulated Garage Door and Opener much more comfortable.


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.


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.

At the same time 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!

All this is fancy stuff but the bottom line is our new Insulated Series garage doors will help regulate the temperature and noise in your garage so you can use it the way you want to. Yet another reason to talk to your nearest Dominator Dealer today about a door & opener package that perfectly fits your lifestyle.


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 Dominator.

• Pre-painted steel, to stand up to the harsh New Zealand climate.
• Bottom weatherseal which is soft and pliable, helping to stop leaves and rain coming in under the door.
• Mohair option available to reduce gaps between the door and the door jamb, to keep out the weather.


Your Dominator sectional door will continue to operate like new, with features such as:

• Springs designed to exceed the Aus/NZ Standard for garage doors – 20,000 cycles.
• Factory fitted, muntins and end styles ensure consistent panel tolerances for trouble free operation.


It’s important to have peace of mind when you make a purchase, that’s why your Dominator sectional door comes with the following warranty:

  • 5 years for steel door curtain & associated labour, 1 year for surface coating, locking mechanism & all other components & associated labour.
  • Industrial/Commercial use – 1 year for all components & labour.
