It would be very similar to the types of expansion joint covers that are available except that it would not have to accomodate movement.

I had one project where the rolling loads (racks of mouse cages) were so high that they shredded the trench cover within 2 months after installation. J.

Balco is the only manufacturer that I have found (actually someone else put me onto them).

Use stainless steel if you have a need.

Also not sure by your description on flow capacity requirements.

This lab was retrofitted in an existing building so the contractor had to cut the slab and install trenches. The product worked great though we did not exactly match the existing VCT floor.
