Seamless Steel Tube
Seamless steel pipe is widely used. The general purpose seamless steel pipe is produced by ordinary carbon structural steel, low alloy structural steel or alloy structural steel. The output is the largest, and is mainly used for conveying fluid pipes or structural parts.
Seamless steel pipe has a hollow section, a large number of pipes used for conveying fluid, such as pipelines, such as oil, natural gas, gas, water and some solid materials. Widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing circular parts, can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.

Square Or Rectangular Tube
A Hollow Structural Section, or HSS, is a type of metal with a hollow tubular section. These sections can be circular (CHS), square (SHS) or rectangular (RHS). Hollow Structural Sections, especially RHS steel is commonly used in welded steel frames while SHS and CHS are more often used in columns. Hollow Steel Sections are also commonly used as beams.
The usual delivery length of the square moment tube is 4000mm-12000mm, with the majority of 6000mm and 12000mm. The square tube is allowed to deliver short and non - scale products that are not less than 2000mm, and can also be delivered in the form of an interface tube, but the buyer should remove the interface tube when it is used. The weight of short and non - scale products does not exceed 5% of the total deliveries, and the square moment pipe with theoretical weight greater than 20kg/m should not exceed 10% of the total delivery.
