I'm not sure if there is a steel mesh for that purpose, but I do know there are concrete pavers that are for that purpose. They are about 1.5' wide, 2.5' long and about 3 or 4" thick. They have a cut out diamond pattern that allows the grass to grow through and water to escape. They are thick enough to drive on without breaking them. After installed and the grass matures, it is hard to tell they are there.
