It's very much like this except the roof crease is transverse -
The current door is a 3/4" plywood. I'm not after recreating the trim. I'm just after getting the right material to use in the replacement door. FWIW, the shed manufacturer will sell me a door for about $300. The original door is reinforced with 2 by 2s on the inside. From what I saw in the showroom, new doors are reinforced with angle section metal and have insulation.
