EN39 SCAFFOLD TUBE

EN39 Scaffolding Tube

Scaffold tube is frequently used in construction sites to build into platform together with steel couplers, steel planks, in aim to support workers to walk on the high area.

For scaffolding tubes, the BS or EN standard is popular, such as BS1139, EN 39 and MS1462.

Regarding the Southeast Asia market, BS1139 tube is frequently used. Now also some countries require the EN39 scaffold tubes, such as Vietnam, Malaysia for MS1462 scaffolding tubes.

EN39 scaffold tube is commonly used in UK and other Europe markets.

Compared with BS1139 steel pipes, EN39 tube has special requirement on the Aluminium components, it has to be above 0.02%.

Besides the chemical components, a flattening test is requested. The test shall be carried out in accordance with EN 10233, The tube section shall be flattened with the weld, The distance between the platens, measured under load, shall not be greater than 75 % of the original

outside diameter of the tube and no cracks or flaws observed. The test shall be continued until the distance between the platens, measured under load, is not more than 60 % of the original outside diameter and no cracks or flaws observed in the metal elsewhere than in the weld.

With the Aluminium requirement and flattening test, the EN39 tubes has high tensile strength than BS1139 pipe. Accordingly the price is higher than common BS1139 pipes. While some factory use BS1139 tubes to replace the EN39 scaffolding tubes.
