Built to last and easy to install, our interior steel doors are made for standard sized doorways throughout New Zealand homes.

Whether you're a builder or a confident DIYer, you can easily replace your existing door with our Single Pivot Steel Door and Cavity Slider Steel Door for a clean architectural look.

Why Choose a Steel Interior Door?

  • Modern minimal aesthetic

  • Durable steel frame that resists warping or swelling

  • Double-glazed glass for insulation and sound reduction

  • Custom colour options to match your interior design

Which Door Are You Replacing?

We offer two models:

1. Single Pivot Steel Door - Designed to replace standard hinged doors.

2. Cavity Slider Steel Door - Perfect for replacing existing cavity sliding doors in walls.

How To Replace Your Door

First you will need to remove the existing door and unscrew and remove the existing door hinges. You’ll want to ensure the doorway is still square. Sometimes in older houses things can tend to move around a bit. 

Once the opening is square and ready to go, you can use our custom templates to effortlessly line up and secure your new Single Pivot Steel door. If you are installing a Cavity Slider Steel Door, simply lift the new door onto the rollers, secure the safety latch and install your new lower guide to ensure your new door slides effortlessly open and closed.  

More light, more style.

Our steel interior doors enhance your space with natural light and a sleek architectural edge.
