Thanks for posting, Northern. It doesn't sound like the conveyor belts are going to work for me in my situation. The reason I need flooring is because the floor is really smooth slick cement....it was actually built to be an auto-shop. I'm going to need it all the way to the entrance and so getting it getting wet will be an issue.
You could also buy a stone finish for the floor that will rough it up and still be lots tough. Its like a paint almost. Use TSP to prepare the cement, then apply with a roller, I believe.
I do have a lumber mill in my area. If the dimensions aren't the same for the rough cut lumber and pressure treated lumber, won't it look kind of odd if I use both? The floor is cement, so I'm sure there will be plenty of times where I have to take up the stall mats and hose the floor. So I will probably have to use treated on the bottom, right?
Treated on the bottom foot or two would last longer for sure. As for looking funny -- honestly, if looks are terribly important to you, then you've got to $pend. Personally, I don't think it will look funny because it will be consistent from one stall to the next. 1/2" is not going to be noticeable when you are looking down. Where you need to pay attention is if you have a hinge on the treated wood and another on the rough wood, you will have to shim the lower hinge. It's for things like that, that you have to pay attention to the dimensions.
Thanks for your help, Paint. I assumed that the lumber yards would be cheaper than Lowes or Home Depot. That is suprising. Thanks for the tips about the screws. Sounds like I will save myself a lot of time and headaches by investing in a good drill.
In my area, the small name building supply stores and the lumber yards are cheaper on just about everything wood and the fasterners than Lowes and Home Depot. So shop around. Also, service and knowledge are your friend. You might
get service from Lowes/HD, but you absolutely won't get knowledge.
Screws -- yes! Absolutely. Paint is VERY right about that. And spend the extra to get cordless Dewalt power tools if possible. It's well worth it. They do go on sale from time to time for great deals and that's where the franchise stores are your friend.
