At SBB Scaffolding, ensuring the highest safety standards and compliance with industry guidelines is at the heart of everything we do. As scaffolding professionals, we recognize the critical importance of following established guidelines that govern scaffolding design, safety, and installation. Among the most important standards are TG20:21 and TG9:18, which provide essential frameworks for scaffolding systems used in tube and fitting projects and temporary roof structures, respectively.
Both of these guidelines are crucial for ensuring safety, efficiency, and quality across all our scaffolding projects, whether we’re working on a major commercial construction site, a delicate heritage restoration, or a temporary building structure.

What is TG20:21?
TG20:21 is the latest edition of the TG20 series, which outlines the necessary guidelines for designing and installing tube and fitting scaffolding. This type of scaffolding is commonly used for a wide range of projects, from small repairs to large-scale developments. For SBB Scaffolding, TG20:21 represents the gold standard of scaffolding safety and design, allowing us to create secure scaffolds that stand up to the demands of each project.
Key Features of TG20:21
- Design Compliance
At SBB Scaffolding, we understand that scaffolding is not a one-size-fits-all solution. TG20:21 provides comprehensive design principles that ensure scaffolding meets safety requirements for height, stability, and load-bearing capacity. For us, adhering to these principles ensures every scaffold we design and erect is structurally sound and safe. - Safety Guidelines
Safety is our top priority at SBB Scaffolding, and TG20:21 helps guide our teams in following safe installation practices. With detailed instructions on material use, assembly techniques, and risk reduction, we’re able to ensure every scaffold is erected with minimal risk to workers and the surrounding environment. - Custom Design Solutions
Every project is unique, and TG20:21 gives us the flexibility to create scaffolds tailored to specific needs. By following the guidelines, we ensure our custom scaffolds offer the necessary stability and support without compromising on safety or compliance.
Why TG20:21 is Important to SBB Scaffolding
At SBB Scaffolding, we take pride in our commitment to safety and compliance. By following the TG20:21 guidelines, we ensure that all our tube and fitting scaffolding projects are built to the highest standards, reducing the risk of accidents, delays, and costly mistakes. Whether it’s a routine scaffold for maintenance or a more complex construction project, TG20:21 provides the framework that guarantees safe, reliable scaffolding solutions for our clients.
What is TG9:18?
For SBB Scaffolding, TG9:18 is another critical guideline, especially when working on heritage projects or creating temporary structures. This guide outlines best practices for scaffolding that supports temporary roofs and buildings—structures that are essential for protecting heritage sites during renovations or creating additional workspaces on construction sites. TG9:18 helps us design scaffolding systems that ensure stability and safety, particularly in challenging environments.
Key Features of TG9:18
- Design Guidelines
TG9:18 provides clear design instructions for scaffolding supporting temporary roofs and buildings. From load-bearing capacities to wind loads, the guide ensures our temporary structures are capable of withstanding environmental stresses. For SBB Scaffolding, this means creating robust and reliable temporary roofs that protect heritage buildings during restorations. - Risk Assessment
Before we begin any project, TG9:18 encourages a thorough risk assessment. This is something we take very seriously at SBB Scaffolding. Whether we’re erecting scaffolding for a heritage building or installing a temporary roof, assessing weather conditions, ground stability, and structural integrity ensures we anticipate and mitigate any potential hazards. - Best Practices for Erection and Dismantling
TG9:18 outlines the safest methods for erecting and dismantling temporary structures. We follow these practices closely to ensure that scaffolding systems are safe throughout the project and properly dismantled once the work is complete, reducing risks to workers and surrounding properties. - Exclusions and Special Considerations
TG9:18 helps clarify which types of scaffolding are excluded from its scope and which should follow alternative standards. Understanding these nuances allows SBB Scaffolding to apply the right standards to the right projects.
Why TG9:18 is Crucial for SBB Scaffolding
For SBB Scaffolding, TG9:18 is invaluable when working on temporary roof systems, especially in projects involving heritage buildings. Protecting these structures from weather damage during renovations or construction is vital. By adhering to the guidelines in TG9:18, we ensure our temporary scaffolding systems provide the necessary support, stability, and safety—protecting the building, workers, and materials on-site.

Ensuring Safety with TG20:21 and TG9:18 at SBB Scaffolding
For SBB Scaffolding, understanding and adhering to TG20:21 and TG9:18 is crucial for delivering scaffolding solutions that are not only safe but also compliant with industry standards. These guidelines ensure that we can provide our clients with reliable scaffolding systems, whether we’re working on large construction sites or delicate heritage restoration projects.
By following these comprehensive guides, we’re able to offer safe, effective scaffolding solutions that protect both workers and the buildings we serve. For any scaffolding project, TG20:21 and TG9:18 serve as the blueprint for success and safety.
