Angle steel iron is a commonly used building material used to support and connect structural members and has excellent strength and corrosion resistance. A36 steel angle bars means that the material meets the requirements of the American ASTM A36 standard.

Although casing pipe and carrier pipe are similar in name, they are different in structure and function.

Angle steel, also known as angle iron or l shaped angle steel, is a long steel bar with two sides perpendicular to each other. The cross-section of angle steel is usually L-shaped, and it is usually made of hot rolling, cold drawing or welding.

Steel sheet pile is a type of steel with a lock. The cross-sections include linear, Z-shaped, U-shaped, H-shaped, hat-shaped, etc.

Boiler steel plates mainly refer to hot-rolled medium-thick plate materials used to manufacture superheaters, main steam pipes and boiler firebox heating surfaces.

The most fundamental difference between ASTM A53 Grade A and Grade B steel pipes is their mechanical properties, especially their minimum yield strength and tensile strength.This makes Grade B more suitable than Grade A for high pressure applications.
