Glass top cutting table (deep scratches)

Recommended Posts

Hello peeps, we have been using a 74" x 110" glass top table as our main cutting surface for most of our Solar, Security and frost/etch films. The glass is regular annealed and over the last 10 years we have replaced it 3 times because of deep scratches due to various reasons (carbon blade, blade angle vs too much pressure, dragging heavy boxes across table with dirt or staples scathing glass top etc) I called our local glass company to talk about what glass would be less apt to get deeply scratched and they tell me that there is not much difference between regular annealed and tempered when it comes to scratching the surface, and if the tempered surface scratches too deep, the glass could shatter. All of the edges of the glass are totally protected using a 1" aluminum flat bar which we then use a drywall T-Square to use as straight edges.  Any extra advice on glass types (annealed, tempered, heat strengthened) vs deep scratches would be greatly appreciated. PS. the new table is going to have some new rules around it for sure!

We use huge ass cutting mats in our production area.. The only way to make anything last longer is to take care of it. You are cutting film not 2x4's . Encourage Stainless blades only in your shop . Toss the carbon blades. Make rules about film only on the glass.


If you do decide to go tempered. Keep the logo side up. The only downfall of tempered is the earth shattering KAboom when its had enough of your $h!T.
