Dan the Race Deck is a stable product , it doesn't expand or contract .
It doesn't move under load even turning the wheels and supports 80,000 pounds .
The flow through doesn't make any noise when you walk on it .
I use it in other garage in the area where the tires roll and use the solid non shinny in areas everywhere else .
Except the area under the Airstream I used the shinny and slippery ones there so I could lay on the floor and slide under it . But it's slippery when wet .
The solid ones do make a slight hollow sound when walking on them.

When I installed them in the Airstream garage I cut them to fit around the feet of the lift in there.

I strongly recommend Race Deck . Call them and have them send you a sample of the flow through and solid .
