Q235B Corrugated Galvanized Roofing Sheet
pressed into three-dimensional patterns, called corrugations,
using a series of rollers in a cold roll forming process.
Different roller die arrangements produce different types of
corrugation,including waves, squares and angles.
Cold rolling allows a thicker and stronger product that also
presents a better appearance than hot-formed steel.
Finished sheet is then sheared off to the desired length.

Product information
Immersing it in a zinc bath maintained at 460 degree centigrade carries out hot dip galvanizing of the strip. The chemistry of the bath is carefully controlled to ensure proper adhesion and formability of the applied zinc together with bright blemish free uniform spangles.The galvanized coils are chromated to improve its resistance to white rust. The chromating parameters are continually monitored and sheets are regularly tested through salt-spray tests to ensure the performance of this process.
