BS1139 galvanized scaffolding standard is the most commonly used standard. It uses internal and external hot-dip galvanizing process. The outer diameter of this steel pipe is 48.3mm and the wall thickness is 4.0mm. According to BS EN ISO standards, the carbon, silicon, phosphorus, sulfur, nitrogen and other elements are strictly analyzed and controlled.
Bs 1139 Galvanized Steel Pipe The chemical composition of carbon, silicon, phosphorus, sulfur, nitrogen and other elements needs to meet certain requirements. Specifically, the carbon content shall not exceed 0.20%, the silicon content shall not exceed 0.30%, the phosphorus content shall not exceed 0.05%, the sulfur content shall not exceed 0.05%, and the nitrogen content shall not exceed 0.009%. For hot-dip galvanized steel pipes, the silicon content cannot exceed 0.05%.
The mechanical properties of BS1139 sch40 gi steel pipe include tensile strength, yield point and elongation. According to the BS1139 standard, the tensile strength (R m) should not be less than 340 N/mm2, the yield point (R eH) should not exceed 480 N/mm2, the elongation (A) should not be less than 235 N/mm2, and The actual elongation should not be less than 24%.

Medium Galvanized Steel Pipe
The standard size deviation of BS1139 Hot Dipped Galvanized Scaffold Tubes is also one of the important technical requirements. For a steel pipe with a wall thickness of 4.0mm and an outer diameter of 48.3mm, the deviation requirement of the standard quality TYPE4.0 is that the allowable deviation of the wall thickness is within the range of -10.0%, the outer diameter including ovality should be maintained at about 40.3mm, and the inner diameter The allowable deviation is between +0.5mm and -2.6mm.
