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 flat square surfaces of RHS has the ability to ease construction, and they are sometimes preferred for architectural aesthetics in exposed structures, but circular Hollow Structural Sections are becoming more popular in exposed structures for the same reasons.
Our company provides a square tube main brands, ASTM A500, ASTM A36, ASTM A572GR50, the allowable deviation of square pipe wall thickness, when not more than plus or minus 10% of the nominal wall thickness of the wall thickness is less than 10mm, when the wall thickness is greater than 10mm plus or minus 8% of the wall thickness, bending angle and weld zone wall thick except.
The usual delivery length of the square moment tube is 4000mm-12000mm, with the majority of 6000mm and 12000mm. The 2x3 rectangular tubing 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.
