A36 A53 Grade B Galvanized steel pipe
A36 A53 GradeB Galvanized steel pipe is a galvanized steel pipe that meets specific standards. Among them, A36 is a common carbon structural steel standard with good strength and toughness; A53 GradeB is a standard for seamless and welded steel pipes established by the American Society for Testing and Materials (ASTM). GradeB means that the grade of the steel pipe is B, which usually has higher quality and performance. This steel pipe is galvanized to form a layer of zinc coating on the surface, which can effectively prevent the steel pipe from rusting and corrosion and extend its service life.
