Garage Steel Gauges explained

How do steel gauges affect my garage door?

Steel gauges refer to the Base Metal Thickness (BMT) of your garage door.

Each garage door has its own BMT, influencing the scratch and dent resistance afforded to your garage door.

We use COLORSTEELĀ® where possible, which provides an excellent range of colours and superior scratch and dent resistance.

Below are a list of steel gauges (BMTs) our garages come in, and how they influence your garage door.

Our Garage Door Steel Gauges:

Icon with text that reads "STEEL GAUGE 0.4 BMT"

0.4 BMT

A lighter weight steel which provides the flexibility needed for our Series A and Series B roller doors. When combined with the deep ribs in the roller door this creates a strong secure door.

Icon with text that reads "STEEL GAUGE 0.55 BMT"

0.55 BMT

This thickness allows the steel to be roll formed and allows us to produce the widest range of styles. Also a very common thickness for secure roofing the 0.55 BMT allows for a strong yet cost effective Sectional door.

Icon with text that reads "STEEL GAUGE 0.6 BMT"

0.66 BMT

Used for our Somerset and Georgian Sectional doors the slight increase in thickness allows for an even stronger door and allows for the extra stretch required to form the pressed panels.

Icon with text that reads "STEEL GAUGE 0.75 BMT"

0.75 BMT

The thickest of the steel we use for our doors this superior heavy gauge steel must be folded instead of roll formed, reducing the range of styles available. The thickness allows for the panels to be a lot flatter than other plain panels and provides even more resistance to dents.

Steel gauges in the real world

How do steel gauges translate into real life applications?

0.4-0.55 gauge is often used for steel roofing, with 0.4 being the minimum per NZ building code.

You'll find heaver gauges such as 0.6, 0.75 and onwards in hardier roofs, steel framing and structural steel applications.

Your garage door is made and tested for New Zealand's conditions.

Our garages come in a variety of steel thicknesses to suit your environment.
