Not sure yet. Since the elevator system is enclosed I was thinking of starting off with dull aluminum or nickel and ask the customer if he wanted any weathering. The conveyor itself will be enclosed per customer specs so may be the same scenario but we are still designing the ground level loading shed. The original design was enclosed with an opening for the conveyor and a door on the opposite end but it dawned on me there must be another opening to load the coal onto the conveyor........ If the shed ends up being open then it has to be dirty. Some more things for the customer and me to mull over.
