ASTM A36 Hollow Section refers to hollow structural steel tubes manufactured using ASTM A36 carbon structural steel.

Black iron pipes and galvanized pipes are two common types of carbon steel pipes widely used in construction, plumbing, and industrial systems.

Drill pipe is a fundamental component of the drill string. It is made of seamless steel tubing (with a wall thickness typically between 9 and 11 mm). Its main functions are to transmit torque and deliver drilling fluid, and to deepen the wellbore by gradually lengthening the drill pipe.

In the building materials market, structural steel has become an indispensable raw material in various structural and building projects. Among common structural steel sections, such as U-Beam, V-Beam, I-Beam, and H-Beam, two—I-Beam and H-Beam—are often easily confused due to their similar Beam.

Concrete Weight Coating (CWC) is a heavy reinforced concrete layer applied to the external surface of steel pipelines. Its primary function is to provide negative buoyancy, mechanical protection, and structural stability, especially in offshore and underwater environments.

FBE (Fusion Bonded Epoxy) coating is a single-layer protective system that forms an anti-corrosion coating on the surface of steel pipes through an electrostatic spraying process.
