Reliance Metalcenter in Union City offers G30 galvanized steel sheet in stock and ready to ship, with next day delivery available to northern California. G30 galvanized steel sheet includes a zinc coating of 0.30 ounces per square foot total on both sides (0.15 ounces per square foot on each side) to protect from rust and corrosion. The zinc is applied through hot-dip galvanizing. G30 galvanized steel sheet has a smooth finish, good formability, moderate corrosion resistance for indoor or mild outdoor environments, and has excellent paintability, especially when pre-treated or primed. G30 galvanized steel sheet is often used in interior construction framing and enclosures, indoor HVAC ducts, electrical boxes and covers, appliance panels, and general sheet metal work when light-to-moderate corrosion resistance is needed.
Reliance Metalcenter in Union City also offers G90 galvanized steel sheet in stock and ready to ship. G90 is another hot-dip zinc-coated steel sheet, but with a much heavier zinc coating than G30, having 0.90 ounces per square foot total on both sides (0.45 ounces per square foot on each side) to provide rust and corrosion protection. G90’s heavy corrosion resistance is suitable for outdoor, wet, industrial, and coastal environments. G90 may look slightly rougher or thicker due to the heavier zinc layer. Common applications for G90 galvanized steel sheet include trailers, utility structures, agricultural buildings, roofing, gutters, downspouts, outdoor panels and siding, exterior HVAC components, and guard rails and posts.
