Built for height, stability & productivity
When working at elevated heights, stability and confidence are critical. Our size 3 builders’ trestles are engineered to provide a secure platform that allows tradespeople to work comfortably without the limitations of ladders.
When used in pairs or more, these size 3 trestles create an excellent low-level or mid-height access platform. They comfortably accommodate four standard 225mm-wide timber scaffold boards or two 450mm-wide lightweight aluminium staging boards. Simply lay your planks across the trestles (max 1.2m apart) to form a strong, continuous platform ideal for plastering, painting, rendering, and other high-level trade work.
For many jobs, this eliminates the need for more complex access systems, saving time and setup costs while still maintaining professional safety standards.

Benefits of size 3 builders trestles
Designed for higher working levels
They are engineered specifically for elevated tasks; these size 3 trestles provide the additional height needed for ceilings, upper walls, and external elevations without compromising stability.
Consistent platform at height
When used with scaffold boards, they create a steady, continuous workspace that allows you to focus on the job rather than repositioning access equipment.
Strong, site-ready construction
They are built from reinforced steel, and are designed to withstand the demands of busy construction environments and regular transport.
Reduces need for larger access systems
They offer a practical alternative to scaffold towers for many jobs, helping minimise setup time while maintaining a safe working position.
Suitable for demanding trade work
These bandstands are commonly used across multiple trades, from large-scale decorating to installation work, where both height and reliability are essential.
What are size 3 builders' trestles used for?
Our size 3 trestles are best suited for high-level construction and finishing work, including:
- Ceiling installation and plastering
- High wall painting and decorating
- External rendering and façade work
- Window fitting at height
- Mechanical and electrical installations
- Refurbishment and structural work
They are commonly used where a larger working height is required, but full scaffold access isn’t practical.
Built to industry standards
They are manufactured in accordance with BS1139 requirements and are designed to meet established UK expectations for strength and safety.
The structural design focuses on maintaining stability under load at increased heights, with reinforced sections that improve durability during repeated use. This makes them a dependable option for professionals who require consistent performance across multiple projects.
Frequently asked questions
What high-reach tasks are they designed for?
They are perfect for high-level ceiling painting, installing or repairing light fittings, coving and cornice work, high wall plastering, or cladding work on single-storey extensions. They bridge the gap between standard trestles and full scaffolding for jobs that still fall under low-level access rules.
Does the extra height of size 3 trestles require additional safety precautions?
Yes, always treat the upper end of the 1.68m range with extra care. Ensure the ground is perfectly level, use sole boards, and consider adding handrail posts (where available) for added security. Their robust 10.5kg construction provides the necessary rigidity at taller heights when set up correctly.
How stable are they when fully extended compared with smaller sizes?
The taller frame is engineered with additional bracing, and when pinned correctly, they remain extremely stable thanks to the 970mm width and BS1139 compliance. Many roofers and ceiling specialists we supply confirm they feel more secure than equivalent height alternatives.
Can they be used for creating elevated display or event platforms?
Yes, they are popular with event companies and exhibition contractors for creating temporary stages or display plinths at 1.2m–1.6m. The adjustable height lets you match exact venue requirements while maintaining a high safe working load.
What maintenance is recommended for them due to their taller design?
It is recommended to inspect the leg pins and welds more frequently than on smaller sizes, especially if used outdoors regularly. The galvanised steel with red powder coating offers excellent corrosion resistance, but wiping down after use in wet conditions extends service life significantly.
Are they suitable for outdoor work on uneven sites?
They perform very well outdoors, provided you use adequate sole boards or base plates to spread the load and level the platform. Their extra height makes them ideal for external rendering, soffit work, or gutter repairs on low-rise buildings.
How many size 3 trestles do contractors typically use for longer runs?
Most use them at 1.0m–1.2m centres (never exceeding 1.2m) for heavy loads. For lighter ceiling work, 1.5m spacing is sometimes acceptable after a site-specific risk assessment, but always follow the 460kg SWL guidance at 1.2m centres.
When is size 3 the only practical choice over size 1 or size 2?
Whenever your required working height exceeds 1.2m, the size 3 becomes the safest and most efficient option. Using two smaller trestles stacked or combined is never recommended. This size provides the correct single-platform solution that complies with industry best practice and keeps your team safe and productive.
