■ Overview
A53GrB zinc coated pipe,HDG pipe A53Gr.B,Galvanized pipe A53grb is mainly used for roofs,outer walls,ovens,explosive-proof steel.When using A53GrB galvanized steel pipe,the zinc reacts with oxygen and become a protection layer for future corrosion.And galvanized steel materials sometimes can replace of stainless steel materials in advantage of its cheaper price.
