Interior Signage

The signs inside a building do two jobs at once. They get people where they need to go, and they tell everyone who walks in what kind of place this is. We design, make and install interior signage that does both, from a single door plaque to a complete wayfinding scheme across every floor of a building.

Cutting, finishing, printing and assembly all happen in our own workshop in Bolton, Greater Manchester, so the sign you approve is the sign that arrives on site. Our own teams then install it, whether the building is in Manchester or anywhere else in the UK.

What we make

Finished to match your interior

Interior signage is seen at arm’s length, under office lighting, often for years. That makes the finish matter more than almost anywhere else. We CNC cut acrylic and aluminium to shape and paint to exact references, including metallic finishes and any RAL colour, so your signage sits properly alongside the doors, frames and ironmongery around it.

Designed for everyone who uses it

Good interior signage has to work for every visitor. We design to BS 8300 and Approved Document M, with the contrast, character heights and mounting positions that make signs readable for people with visual impairments, and we manufacture tactile and braille signage in house.

See it before it is made

Before anything goes into production, we show you exactly how it will look in place, with visuals of the signage in your building and physical samples of the finishes where you need them. Nothing is manufactured until you have approved it.

Questions we’re often asked

What finishes can interior signs have?

Almost anything. We paint to any RAL colour and to metallic finishes including bronze and satin nickel, matched to the ironmongery and frames around them.

How are interior signs fixed?

Usually bonded with high strength adhesive tape or fixed on concealed locators, so there are no visible screws.

Can you work from our designer’s drawings?

Yes. We regularly manufacture to designs from architects, interior designers and wayfinding consultants.

Can I see samples first?

Yes. We produce physical samples of the finishes before manufacture wherever you need them.

Do you work outside Greater Manchester?

Yes. We are based in Bolton but manufacture and install across the whole of the UK, including multi site rollouts and framework contracts.

Are you accredited?

Yes. We hold ISO 9001, ISO 14001 and ISO 45001, and Principal Contractor accreditation with SafeContractor.
