Details Introduction
- Standard Specifications The full name of the EN39 standard is "loose steel tubes for tube and coupler scaffolds," which specifies the requirements for non-alloy steel pipes used in conjunction with couplers conforming to the EN74 standard for erecting scaffolds and work supports in construction.
- Material Requirements Typically made from materials such as Q195, Q215, Q235, Q345, as well as S235JR, S355J0, similar to China's QA235B material.
- Dimensions and Specifications The outer diameter is usually 48.3mm, with wall thicknesses of 3.2mm (Type 3) and 4.0mm (Type 4). Common lengths are 6m or 6.4m, customizable upon request, with a minimum length of 0.5m and a maximum length of 12m.
- Surface Treatment Generally treated with hot-dip galvanizing, with a zinc coating thickness usually required to be no less than 40 microns to enhance corrosion resistance.
- Mechanical Properties Taking S235GT material as an example, its yield strength is not less than 235MPa, and tensile strength is not less than 340MPa; for S355GT material, the yield strength is not less than 355MPa, and tensile strength is not less than 470MPa.
