This guidance gives details of the stress corrosion cracking (SCC) that can occur in certain materials when subjected to tensile stress and specific corrosive environments. Although rare in our industry, it can lead to unexpected sudden failure of certain metals. Whilst chemical environments and alloys are highly specific, this guidance explains the process by which SCC can occur and advises that specialist advice may be needed where SCC is possible or has occurred in the past. This guidance is available for pdf download 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.
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.
This guide is intended to aid those who commission scaffold designs by summarising the responsibilities of each party involved at each stage of the process. It also details the requirements for preparing a design brief with information required by the Designer to enable a suitable and sufficient design to be produced, as well as outlining the design process, checking requirements and expected output information. This document is complimented by CG6: Scaffold Design. 6 pages.
A temporary roof or building is a sheeted structure designed to protect the area inside from the effects of weather, dust, etc. This guide is intended to give design and construction information to the suppliers and erectors of temporary roofs and buildings and intended for use by contractors during the building process. 56 pages
