Do they make industrial strength laptop keyboards?

My old computer keyboard had the letters worn off of most of the keys and a worn place almost completely through the space bar on the right side. I paid attention and I do use my right thumb to press the space bar when typing. I kept using it, because I know where the keys are, but it wore out in other ways and I had to replace it.

I have had my new laptop for just over a couple months now and the space bar on the keyboard is starting to get worn on the space bar in the same spot. Washing that spot doesn't seem to remove the worn looking place. Everything else seems to polish up nicely. So, I know it's not dirty. It's just worn.

My question is do they make industrial strength keyboards or at least space bars? That poor space bar seems to take the most wear and tear. Maybe plastic (or whatever most laptop keyboards are made of) isn't my best option.
