Scaffolding BS1139 standard is a British standard for scaffolding installation, specifying the specific parameters of the size, thickness, material and load capacity… of the materials used for the scaffolding. This standard also covers a system of pipes tightly linked together by clamps, couplers, putlogs, boards, ladders…
In the following article, we will learn more helpful information about this scaffolding standard: history, applicable organization, essential components of prefabricated scaffolding, and how this standard is applied at VIVABLAST.
There are four main ideas in this article including:
In 1974, at Denmark’s request, CEN/TC 53 started work on standardizing “Maintenance and working trusses made of prefabricated elements – Materials, Dimensions, Design loads and Safety Requirements.” As a result, twelve draft proposals were studied. At its 19th plenary meeting in March 1984, CEN/TC 53 published a draft amendment in the form of an Instrument of European Concord.
In November 1986, CEN/TC 53 decided to propose an amended Harmonization Document and sent it to the Central Secretariat for a final vote. Once there are International Reference Standards for materials and safety factors in place, this Harmonization Document can be considered for adoption as an EN.
During the draft discussion, it was recognized that the average human height is gradually increasing, so it is necessary to consider versions for vertical resizing. CEN/TC 53 is undertaking work to prepare European Standards for:
Under the General Rules of CEN/CENELEC, these countries will be obliged to implement the Instrument of Harmonization: Finland, France, Germany, Greece, Ireland, the Netherlands, Norway, Portugal, Spain, Switzerland, Sweden, Switzerland, and the United Kingdom. And this is how the Scaffolding BS1139 standard was established.

To create a scaffolding system that meets the scaffolding BS1139 standard to ensure the safety and quality of the work, the construction contractor must acquire many different conditions.
Scaffolding BS1139 is a scaffolding system made up of galvanized steel pipes that are tightly connected by accessories such as swing shackles, couplers, clamps, putlogs, boards, ladders,…
Detailed specifications are shown in the tables below:
1. Tubes
| Outer Diameter (including coating) | 48.3 mm (± 0.5 mm) |
| Pipe wall thickness | 3.2 mm 3.6 mm 3.8 mm 4.0 mm |
| Materials | Steel Hot-dip galvanized steel (corrosion resistance and high durability) |
| Requirements | Hardness Tensile strength |
2. Scaffolding clamps and couplers:
| Elements | Essential clamps Rotating clamps Pipe-connecting clamps Single clamps Clamps of the cheeks Clamps of beams Clamps of bipedal planks |
| Material | Steel Galvanized steel (corrosion resistance and high durability) |
| Requirements | Hardness Tensile strength |
| Application | Shackles and scaffolding clamps are used to necessarily link 2 sections of steel pipes with diameters from 42 to 49 mm together and insist on beams Scaffolding and tubes are used to ensure rigidity and stability. |
3. Scaffolding boards:
| Width | 310 mm – 360 mm |
| Length | 1000 mm 1500 mm 2000 mm 3000 mm |
| Material thickness | 1.2 mm 1.5 mm |
| Materials | Ton zinc Hot-dip galvanized steel (corrosion resistance and high durability) |
| Requirements | Hardness Tensile strength Withstand large loads (according to the design) Flat surface with non-slip holes Safety keychain (optional) |
| Application | Used to create a workspace for the construction operator |
