How much weight will this support


I have a wooden platform, made of 1.5 inch thick redwood. The platform looks like this, with a dimension of 5 feet X 28 inches X 7 inches. It seems to be heavy, at least around 50lbs or more. The picture is of the underside of the platform.

I would like to hang this platform from the sides of two redwood planters at each end.

Each planter is made of of 1.5 inch thick redwood pieces. The planter dimension is 31 inches X 13 inches

So basically the final arrangement would be to have each planter at both ends and the platform hanging/resting on a reverse L shaped piece made of 1.5 inch thick redwood and bolted to the planter. The sides of the platform will rest on the opening of the reverse "L". Each "L" piece would be bolted using 2, 3/8"x5 inch hex bolts.

I am curious if this arrangement will support the stress. This is meant to be used as a patio bar.


Thanks!

that should work though the planter is 13" and the platform 28, so you will have to figure out where/how to mount the platform to the planters. maybe bolt the planters down to make them stonger or add reinforcements and then bolt the platform.

Good question . I was concerned about that. I can make the planter pretty heavy by putting bricks or rocks in it. It's already decently heavy but so is the platform. Any other ideas?

Thanks!

bolt both planters down and add the platform between them, this should hold them up

add blocking at the bottm of planter internally and go from below deck and add screws/bolts up through into planter blocking

Thank you!

The challenge here is that this thing will be sitting on a concrete patio, not a wood deck. Would rather not drill into the concrete to bolt the planters. Any other way to stabilizing the planters?

add/nail/screw 2x4's to the sides at the bottom of planters that stick past the planter toward both the front and the back( 4 pieces total , 2 per box). let the 2x's stick past one foot and that should foot it. you do not need them sticking sideways because the entire thing put together will keep it from tipping sideways.
