Does Aluminium Thickness Really Matter for My Garage Door?
It’s a question we hear regularly from homeowners comparing garage door quotations:
“Surely aluminium is aluminium, right?”
The short answer is: No, not all aluminium garage doors are created equal.
When you’re investing in a new garage door, it’s important to look beyond the price and understand exactly what you’re getting for your money.
Why Does Aluminium Thickness Matter?
The thickness of the aluminium directly affects the strength, stability, durability, and overall appearance of your garage door.
Some suppliers use thinner, rolled aluminium, often around 0.8mm thick. While this may initially reduce the purchase price, the difference can become noticeable over time.
Thinner aluminium can:
- Flex more easily
- Appear wobbly during operation
- Be more susceptible to dents and damage
- Offer less rigidity over larger spans
- Show signs of wear sooner
This is why comparing quotes based solely on price can be misleading.
What Does Immac Systems Use?
At Immac Systems, we believe a garage door should be a long-term investment.
That’s why we prefer installing extruded aluminium garage doors, typically manufactured from 1.5mm or 2.2mm aluminium profiles.
The benefits include:
Superior Strength
Thicker extruded aluminium provides greater structural integrity, helping the door maintain its shape and stability over many years of use.
Better Appearance
A stronger profile creates a more solid, premium look and feel, without the waviness or flex often associated with thinner alternatives.
Improved Durability
Garage doors open and close thousands of times during their lifespan. Thicker aluminium is better equipped to withstand daily use and the coastal conditions we experience along the Garden Route.
Long-Term Value
While a higher-quality door may cost more upfront, it often delivers greater value through longer service life, reduced maintenance, and a better overall ownership experience.
How Can You Tell the Difference?
The best way is to see and feel it for yourself.
A specification sheet may simply say “aluminium garage door,” but that doesn’t tell the full story. The thickness and manufacturing method make a significant difference to the final product.
That’s why we encourage homeowners to visit our showroom and compare the options firsthand. Once you feel the difference between thinner rolled aluminium and thicker extruded aluminium, the quality becomes immediately apparent.
The Bottom Line
When comparing garage door quotations, always make sure you’re comparing like-for-like products.
Ask questions about:
- Aluminium thickness
- Whether the aluminium is rolled or extruded
- Warranty coverage
- Expected lifespan
- Overall build quality
A garage door is one of the largest moving parts of your home. Choosing quality materials today can save you money, frustration, and future repairs down the line.
At Immac Systems, we believe quality matters. That’s why we install products that are built to last and perform reliably for years to come.
