Metal Galvanized Roofing Sheet consists of hot-filled galvanized metal sheet and other metal sheeting, that are rolled and then cold-forming into different corrugated shapes. As per the desired surface condition, they may be divided into flat spindles, small rounded spindles, flat whole metal products and spot metal products. The flat spindles and small rounded spindles are used for internal roof deck as well as external roof deck. The flat spindles are formed by welding or metal caging while the rounded spindles are formed by forging. However, when flat spindles and rounded spindles are used for internal as well as external roof decking, flat galvanized roofing sheet is widely click here.
Flat galvanized roofing sheets are manufactured with the assistance of metal electro galvanizing equipment. Initially, the metal spangle is manufactured using steel feed and roll process. Then, it is further processed to give shape to the metal spangle. After the metal spangle is shaped, it is cut into different sizes using standard G shaped saw. After each cutting process, theoretical weight of each piece is calculated to determine material specification and cut length.
For external roof decking, metal galvanized roofing sheet is manufactured in two-inch size. Generally, galvanized steel sheets are manufactured in six-inch size. The galvanized sheets are then welded onto galvanized steel beams. After welding, the metal roofing sheet is painted with gloss paint to provide long-lasting protection. This coating also prevents corrosion.
