Coating on exposed canopy steel
The draft says the coating follows the corrosion specification. Outdoor steel over a gate or a drop-off is not indoor shop primer.

Steel skylights and steel canopies, including glass canopies that sit inside a window contract.
Name the environment
A canopy in a coastal city and a canopy in inland Anhui do not take the same system. If the spec is silent, say the location and whether the steel is fully exposed. Do not leave only the word galvanized.
Edges and site welds
Site welds and cut edges lose the shop coating. The specification should say how those spots are repaired. That repair is part of installation, not a later touch-up argument.
Colour of steel against the panel
Exposed canopy steel is often required to match the aluminum panel, and a shop primer will not. Name the finish colour and the gloss, and say whether a site topcoat is allowed. Matching by eye after installation is not a specification.
