Introducing TG30
The new good practice guidance for system scaffolding
NASC has developed TG30 with the support of leading system scaffolding manufacturers as the new definitive guidance for system scaffolding.
TG30 compliance sheets provide a compliance solution for system scaffolding consistent with the industry leading TG20 for tube and fitting scaffolding.
TG30 compliance sheets are now available for TG30 compliant rosette scaffolding systems, with other scaffolding systems coming soon in 2025.
Includes the innovative TG30 eGuide software, TG30 Operational Guide and TG30 Design Guide.
Industry standard compliance sheets
New TG30 compliance sheets for system scaffolding complement the industry standard TG20 compliance solution for tube and fitting scaffolding.
Easy to follow good practice guidance for scaffolding contractors and clients to ensure compliance with standards.
Choose from standard arrangements of scaffolding checked by calculation to BS EN 12810, BS EN 12811 and related codes of practice.
Scaffolds that are TG20 or TG30 compliant are in accordance with Schedule 3, Part 2 of the Work at Height Regulations 2005 and do not require bespoke design.
Industry support
The application of consistently high standards is key to both safety and productivity on construction projects. Almost everyone on site works off a temporary working platform at some point, and should be able to carry out their job confident in the knowledge that scaffold structures have been properly designed and constructed.
Written by NASC and industry experts, supported by structural research and calculations, and eliminating the need for bespoke designs on the most commonly used structures, TG20:21 sets the standard for scaffolding across the UK.
