TECHNICAL DATA
Steel products will be rollformed from ASTM-A-446 grade D (50,000 psi minimum yield),
G-90 hot dipped galvanized coil.
Aluminum products will be rollformed from 3003-H-16 aluminum alloy coil.
Paint finish is a baked on polyester finish of at least 1 mil thickness applied in a two
coat system to all finish sides. The underside of all coated material will have a white
wash coat primer. |
