This guidance gives details of various methods available for satisfactorily securing scaffold boards to prevent movement. Users should satisfy themselves when/which boards require tying down and that any proprietary equipment or fixing method selected meets their requirements. This product is available in PDF format only. 4 pages
This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
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
TG4:19 had amendments predominantly in relation to the orientation of ring bolts where current thinking is that settlement is probably greater than side wind loads so reduces potential shear loads on the bolt. Other minor changes were cosmetic. A recent update in April 2019 saw the removal of one reference only when the guidance was reissued as TG4:19. 24 pages
This document provides guidance for covering 50mm gaps in scaffold platforms through which standards protrude, as well as for covering larger gaps in decking which, due to width restrictions or obstructions, cannot be fully boarded in the conventional way. This guidance is PDF only.
The effects of heat on scaffolding equipment can have a significant and permanent effect on its strength and performance. This guidance explains the potential issues and the action to be taken if equipment has been subjected to a fire or similar conditions. This guidance is available for pdf download only.
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
TG20 provides the definitive guidance for scaffolding constructed with tube and fittings throughout the UK. TG20:21 builds on TG20:13, and makes the eGuide software, Design Guide and Operational Guide available via the new NASC ePortal, on a subscription basis. The eGuide produces pdf compliance sheets, which now include more information and an illustration. The guides are fully searchable online. The ePortal is available here from computers, tablets and smart phones via web browsers. Each subscription gives access from multiple machines, but only one machine at a time. Purchase and use of a subscription implies acceptance of the subscription agreement, found here, by all users. There will be a delay between a purchase on the website and activation on the ePortal. Purchase activation will only take place during normal office hours. The price shown includes VAT at 20%. To pay the NASC member price, log in to the web site before completing your purchase. To renew more than one subscription please add serial numbers to the basket one at a time.
BS2482:2009 defines both visual and machine strength grading standards for 38mm x 225mm boards supported at 1.2m spans and 63mm x 225mm boards supported at 2.5m spans; and machine strength grading standards only for 38mm x 225mm boards supported at 1.5m spans. This guidance is reviewed on the basis of removing A grade boards that should not exist. A visually graded board is still a BS2482 product and should be marked as such on the end band. 6 pages
