Q235B Corrugated galvanized roofing sheet

Corrugated metal starts with carbon steel sheet which is then
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.

Q310GNH Steel

often referred to by the genericized steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. The original COR-TEN received the standard designation A 242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A 588 (COR-TEN B) and A 606 for thin sheet. All alloys are in common production and use.
