UK manufacture, fast turnaround

Graham Sweet Studios has been manufacturing custom 3D letters, signs and logos since 1969. Over more than 50 years we've produced everything from reception signs and retail displays to exhibition lettering, branded displays and television props.

Every project is manufactured to order in our Cardiff workshop using modern CNC cutting, specialist finishing techniques and traditional craftsmanship. The result is 3D lettering that not only looks impressive but is designed around how it will be used.

Whether you have production-ready artwork or just an initial sketch, we can manufacture letters, logos and shapes in almost any size or font, accurately matching brand colours and design guidelines. Samples and finish options are available where required.

From exhibition stands and retail displays to corporate events, wall signs and graduation ceremonies, every project is completed in-house. This allows us to maintain consistent quality, reliable lead times and careful nationwide delivery from start to finish.

Trusted by leading brands

Over the years we’ve worked with businesses of every size, from independent retailers and creative agencies to some of the UK’s best-known organisations. When required, we can also work confidentially on a white-label basis for creative agencies.

Choosing the Right Material

There isn't one "best" material for every project. The right choice depends on where the letters will be used, how long they need to last, how they will be installed, and the overall look you're trying to achieve. For example, lightweight polystyrene may be the perfect choice for a large exhibition stand, while a set of wooden letters could be better suited to a reception area that will be seen every day. If sustainability is a priority, cardboard letters may provide the ideal solution. With over 50 years' experience manufacturing custom 3D letters, we'll help you choose the material that's right for your project, balancing appearance, durability, practicality and budget.
