I can't say that all of these are right for our company but the ones I feel good about, I think are very good. I'm definitely liking sharper edges over rounded. Also, now that I'm looking at these, I'd say the red accents are a good idea to make the logo more noticeable. #1 might be even better with some red..
Also based on your feedback in the earlier round, I wanted to see how it will look if we give the it sharper edges in the main shape of the logo and have it sit on a rounder surface in this case a (circle).
Here are two options with a different font for the CONCRETE PRODUCTS INC. You may find any of those superior regarding the font selection, though I think each has merits.
