How does the price of steel affect the price of a commercial playground equipment?

Commercial playground equipment is made out of steel or aluminum posts, steel decks dipped in plastics, and steel clamps, bolts and other hardware. Also used are steel climbers, overhead ladders, rock walls and other playfield equipment. Slides and climbers are also made out of plastics and steel.

So with gas/oil prices falling how will this affect the price of NEW commercial playgound equipment or NEW school playground equipment?
