0.28mm Iron Metal Steel Plate Corrugated Galvanised Steel Roofing Sheet:
GI roofing sheet is short for galvanized iron roofing sheet. It is profiled with galvanized steel sheet for roofing purposes, which has been coated with zinc. The zinc coating provides the base steel protection from moisture and oxygen.
Galvanized steel roofing sheet combines galvanized steel with corrugated design to provide great strength so that it can withstand harsh weather conditions. The common design includes wavy shape, trapezoidal design, ribbed galvanized roof sheets, etc.It is also lightweight, which makes it easy and quick to install. That’s why galvanized roof panels are widely used in agricultural, industrial, commercial and residential buildings, such as warehouses, makeshift houses, barns, garages, etc.
Galvanized Steel Coil Sheet Production Process The galvanized steel production process includes stages:
1. Contaminant removal: The steel is passed through pickling tanks to remove dirt, grease, and other impurities from the surface. The pickling process is quick and efficient, ensuring that the zinc coating adheres firmly to the steel surface.
2. Sandblasting (if needed): For steel with heavy rust or requiring polishing, sandblasting is performed to clean the steel and prepare the surface for galvanizing.
3. Acid treatment: In some cases, acid may be used to clean the steel surface in detail and remove difficult contaminants.
