Sign Trade Supplies introduces new bolt-down sign post kit for car parks and hard-to-dig environments

New baseplate system simplifies signage installation across multi-storey and built-up parking facilities

Sign Trade Supplies has introduced a new bolt-down sign post kit, designed and distributed to meet the practical challenges of installing signage in car parks and other environments where digging is not possible.

Developed specifically for concrete and reinforced surfaces, the system provides a permanent, secure alternative to traditional post foundations. It is well suited to multi-storey and basement car parks, transport hubs and dense urban sites where excavation is restricted or would risk damaging structural slabs.

The bolt-down kit enables clear wayfinding, safety and information signage to be installed without cutting into decks or disrupting operations. It is built around a four-bolt round baseplate that provides a stable fixing point for post-and-panel signage, while maintaining a clean and professional finish.

Each kit is supplied as a complete solution, including a high-strength aluminium post, a 300mm baseplate, high-tensile bolts and an aluminium cap. Installation is straightforward and can be completed on site using an 8mm Allen key and a PZ2 screwdriver.

Garrick Dartnell, Head of Marketing at Sign Trade Supplies, says: “Car parks are one of the most common environments where digging simply is not an option. This kit has been designed to give sign-makers, installers and facilities teams a reliable, professional solution that can be fixed directly to the surface without compromising the structure below.”

The four-bolt system has been independently strength tested and is 2.5 times stronger than a welded aluminium baseplate. Manufactured from 6005A high-strength aluminium alloy, it offers long-term corrosion resistance and durability in exposed parking environments. The weld-free design also avoids visible weld lines, helping signage remain neat and consistent across a site.

Available in a neutral grey powder-coated finish, with post heights ranging from 1000mm to 3000mm, the kit supports a wide range of car park applications. These include directional signage, bay identification, pedestrian guidance and safety notices.

From an operational perspective, the system is designed to reduce disruption and lead times. Its non-welded construction makes it easier to transport and handle, while the ready-to-assemble format removes the need for fabrication. It also offers a lower-cost alternative to traditional welded baseplates, without compromising strength or performance.

Garrick adds: “This is a practical innovation for both new builds and retrofit projects. We would encourage sign-makers, facilities teams and car park operators to speak with Sign Trade Supplies or their signage suppliers to find out how the kit can be used across their sites.”
