S235, S275, S355 JR/JO galvanized round pipe is a kind of steel widely used in construction, machinery and transportation. These steels are favored for their good performance and corrosion resistance.
A500 standard steel pipes are usually made of low carbon steel with good weldability and mechanical properties. Grade: A500 standard is divided into four grades: Grade A, Grade B, Grade C and Grade D. Among them, Grade B, Grade C and Grade D differ in strength and performance, and Grade C and Grade D usually have higher yield strength and tensile strength.
Q235B is a carbon structural steel. Q235B galvanized square tube has high strength and toughness, can withstand large external forces, and can meet most engineering needs. Its yield strength is 235MPa, and its tensile strength is between 370-500MPa. It has good weldability, is easy to process and install, can be connected with other components through welding process, and is widely used in the construction of various engineering structures.
A36 and A53 GradeB galvanized square pipes are common construction and industrial steels with a variety of characteristics and uses. A36 is a common carbon steel with good strength and toughness; A53 GradeB is a welded or seamless carbon steel pipe commonly used in structural and mechanical applications. Galvanizing can improve the corrosion resistance of steel and extend its service life.
SS400: This is a common structural steel with good weldability and formability. Its yield strength and tensile strength are moderate and suitable for general structural purposes. SS490: This steel is stronger than SS400 and is suitable for structures that require higher strength and durability. It also has good weldability and formability. SS540: This is a high-strength structural steel with higher yield strength and tensile strength and is suitable for structures that require extremely high strength and durability.
S235/S275/S355/JR/JO galvanized square tube is a kind of steel widely used in construction, structural engineering and various industrial fields.
