In wardrobes for example, each Q increase makes the seller an extra 60c.
In Wardrobes you need 5 steel for every wardrobe made
In wardrobes, Q4 steel gains you 1Q in wardrobes
So the math goes
60/(4X5)=3
So each extra q of steel is worth in theory 3c of profit for the wardrobe maker.
So if wardrobe makers actually paid a decent price for the steel, for example, 130+2.5Q the profit margins on steel would be far better.
Hope this might change someone's mind on steel pricing and the market itself.
