Does tempered glass scratch?

Ask any glass manufacturer, supplier or processor worth its salt: tempered glass is tough as nails.

It's this toughness – up to five times stronger than standard annealed glass – that makes it such a critical material in so many applications. But tough or not, can it scratch?

The short answer is yes. But just as tempered glass is stronger than standard glass, so it's more scratch-resistant, too.

When buying tempered glass for a building project, it's important to transport and install it carefully to avoid scratches. And once installed, it's important to be mindful not to damage the glass.

How to safely transport tempered glass

Once the glass is in your hands, you need to ensure it's transported safely. This involves keeping it upright, keeping the panes separated in the vehicle and keeping the cargo securely strapped in place.

How to safely install tempered glass

When installing tempered glass, your installers need to be careful not to cause scratches. This means wearing proper protective personal equipment (PPE), following best practice with regards to carrying and lifting and using tools such as suction cups.

Installers must also be careful not to knock the glass into other objects. Any scratches caused during the installation process will need to be removed. In the worst-case scenario, the materials will have to be replaced.
