Detroit style is a lot like a Sicilian, with a foccacia-like chewy dough and extremely crispy crust which fries in the liberal amount of oil put in the pan for baking.
This recipe is made for this Detroit-style 10x14 pan from LloydPan but should scale easily to other sizes if you adjust the water and flour. The important thing is that the pan needs to be totally flat, so that the crust fries evenly.
