Default Weight Capacity of Steel Plate

I know there are some engineers on here that might know the answer to my question. I need a steel floor plate that will cover a hole in the floor that is 3ft x 3ft and it need to support 5000lbs, how thick of a plate would I need?

I just bought another property and the garage has a sink hole in the floor that is just under 3ft x 3ft and about a foot deep. In the spring I'm going to be ripping the entire thing down but until then I dont want that damn hole open and have some trespassing monkey step in it and break a leg.......we all know how the laws are here in ****achusetts, they pretty much protect the criminals. I will also be parking a 4000lbs machine in that spot from time to time.

Solid steel...not Diamond Plate. If its a true plate of steel you can get away with 1/4 to 1/2 inch of thickness. Granted that its wide enough to distribute the weight to the four corners of the plate. The more you distribute the weight the thinner the piece can be. I would get a 4"x4" plate at 1/4" thickness. Then I would have the four corners drilled and shoot bolts into the floor so it doesn't move.

I'd go for the 1/2" plate. It's a lot harder for some jerk to try and walk away with it, and you can easily drive 1000 lbs over it on a wheeled vehicle (weight on one corner).

i would go 1/2" just for the decrease in deflection if the choice was between 1/4 and 1/2

Now hold on you half inchers...its going to cost more for a 1/2 inch. And the OP is not putting a stack of weights that weigh 5000lbs on it directly. I'm guessing its only one wheel of a 5000lbs or less vehicle that will be resting on the plate. So only a 1/4 of the cars weight will be bearing on the plate.

Plus to drill a stabilization hole in a corner will take much longer. You need something to stop the plate from moving. In Chicago they cover areas of potholes and trenches on the roads with 1.25in steel plates...and those move after time. Mainly from buses and truck hitting them. A 1/4 or even a 1/2in plate will move after awhile.

up here a 4ft x 8ft 1" hot rolled sheet is $275 so guessing less then $100 for a 1/2" 4x4

Hey guys thank you very much for the help, I was going to purchase a 4 x 8 1/2" plate but they wanted $290 locally which seemed really high, but I kinda fell into a 1" 8 x 8...........well actually it was more like bumped into it lol.

While I was checking out all the crap in the houses basement I nearly broke my freaking toe on an old *** boiler..........well the thing is home made with 1" thick steel lol, so I cut off one of the sides and it works amazing.
