ZHONGTIAN Galvanized Angle Steel Bar is a durable corrosion-resistant structural steel profile manufactured through hot dip galvanizing of high-quality carbon steel and low alloy steel materials such as Q235B and Q355B. Featuring a strong zinc protective coating, excellent load-bearing capacity, good weldability, and long service life, it is available in equal and unequal angle designs. It is widely used in steel structures, power transmission towers, construction frames, equipment supports, and outdoor engineering projects requiring reliable corrosion protection.

ZHONGTIAN Precision Cold Rolled Seamless Steel Pipe is a high-performance precision tube designed for applications requiring strict dimensional accuracy and consistent quality. Manufactured through advanced cold rolling and precision finishing processes, it delivers excellent tolerance control, smooth surface quality, uniform structure, and stable mechanical properties. It is widely applied in hydraulic cylinders, precision machinery, automotive parts, automation equipment, and other industries where reliable fit and machining performance are essential.

ZHONGTIAN Small Diameter Cold Rolled Seamless Steel Pipe is a precision steel tube manufactured through multi-pass cold rolling, precision sizing, and heat treatment processes using high-quality carbon steel, alloy steel, and special steel materials such as 10#, 20#, 45#, Q345B, and 40Cr. With a seamless structure, tight dimensional tolerance, smooth surface finish, excellent roundness, and reliable mechanical performance, it is widely used in hydraulic systems, precision instruments, automation equipment, pneumatic systems, and mechanical components requiring high accuracy and machinability.

ZHONGTIAN Hot Dip Galvanized Cold Rolled Seamless Steel Pipe is a precision seamless pipe manufactured through cold rolling or cold drawing processes followed by hot dip galvanizing treatment. It features high dimensional accuracy, smooth surface finish, uniform wall thickness, and excellent corrosion resistance. With a seamless structure and reliable mechanical performance, it is widely used in hydraulic systems, automation equipment, instrument pipelines, and precision engineering applications requiring both accuracy and long-term protection.

ZHONGTIAN Large Diameter Hot Rolled Seamless Steel Pipe is a high-strength seamless pipe manufactured from carbon steel and low alloy steel billets such as 20#, Q235B, Q345B, and 16Mn through high-temperature piercing and continuous hot rolling processes. Unlike welded steel pipes, it is formed as an integrated structure without longitudinal or spiral weld seams, providing uniform mechanical properties, reliable pressure resistance, and excellent structural stability.

ZHONGTIAN Hot Rolled Seamless Steel Pipe is a high-strength seamless pipe manufactured from round steel billets through high-temperature heating, piercing, rolling, sizing, and straightening processes. It features a uniform steel structure, excellent pressure resistance, reliable mechanical performance, and flexible specifications with larger diameters and thicker walls.
