I’d like to order 10 32″x24″ coroplast signs with step stakes. Do you think your standard step stakes can hold such a big sign?

I recommend using two H-frames for a sign of such a size. Wind can easily put a sign on a ground if you use one H-frame for a sign bigger than 24″x18″. Our standard 30″x10″ H-frames are $1/frame if you order them with coroplast signs. Another option is to buy wooden sticks from Home Depot for example and attach coroplast signs to these sticks with screws through washers.
