Fasten Plywood to Steel Bar Grate

[BSVBD]

The general contractor wants to fasten 3/4" plywood to steel bar grate.

Here are my thoughts:

Any other options?

Thank you!

Indoors? Outdoors? What is the application? What will be the loads across the plywood?

I like both your options. It's likely that the plate washer idea is cheaper.

racook... indoor. Stair landing. 100 psf.

jayrod... I also think plate is cheaper. My current ideas are 4-step. I'm hoping there is a simpler, quicker, one or two step process with TEK screws or other.

I can't dream up anything much simpler than that, I guess the hardest part will be ensuring the drilled holes in the plywood line up with the gap between the bearing bars.
