In order to be able to visually identify EN74 certified couplers, this guidance document identifies the specification and minimum markings to be found on all EN74-1:2005 and EN74-1:2022 scaffold couplers, together with brief details regarding the differences between the two standards. This product is available in PDF format only.

Aluminium tubes, prefabricated beams and other components are widely used throughout the scaffolding industry. Whilst aluminium is not as stiff as steel and will deflect more when subjected to equivalent loads, it is much lighter and provides great advantages with regard to manual handling or the reduction weight. As aluminium couplers are not readily available, aluminium tube and beams are invariably connected with steel couplers and joint pins. Unfortunately, when two dissimilar metals such as aluminium and steel are in contact, a phenomenon known as ‘galvanic corrosion’ can occur where the corrosion of one of the metals, in this case aluminium, can be greatly accelerated. In severe cases this could seriously affect the integrity of the scaffold structure.

Many free-standing scaffolding structures, such as access towers, major signboards, fences and enclosures, need to be anchored to the ground, primarily to resist wind forces. Whilst all structures requiring restraint via anchoring to the ground should be subject to a bespoke design produced by a competent engineer, the guidance considers different types of anchors available and typical indicative holding capacities, the possibility of disturbing underground services, the use of guys and scaffold tube restraint. 6 pages
