Introduction to Wallbarn’s Class A Rail Substructure

Wallbarn’s Class A Rail Substructure is an innovative solution tailored for exterior paving systems. It is meticulously designed to offer a non-combustible, heavy-duty substructure, ideal for terraces and outdoor areas. The system seamlessly integrates adjustable height pedestals, aluminium rail bearers, and specially designed lugged headpieces to ensure a sturdy and reliable framework for paving slabs or porcelain tiles. With a minimum build-up of 47 mm (excluding the paving material), this system provides a practical and robust foundation for outdoor flooring.

Key Features and Benefits

Heavy-Duty Construction

The system’s adjustable pedestals are crafted from heavy-duty steel and finished with an exterior grade coating, allowing them to support loads exceeding 2 tonnes each. This ensures a strong and durable base capable of withstanding heavy foot traffic and environmental stresses.

Fire Safety Compliance

Safety is a critical component in outdoor construction, and the Wallbarn Rail Substructure excels in this area. The rails are Class A1 rated according to EN 13501-1:2018 standards and fully comply with BS 8579 guidelines, ensuring top-tier fire resistance.

Seamless Integration

The system boasts specially profiled bearer rails and joists that easily click onto Metalpad and MetalPad EX pedestals. The I Plus single rail and double box aluminium rails attach securely onto pedestals without the need for screw fixings, facilitating a fully integrated and seamless substructure.

Enhanced Stability and Strength

Greater spans between pedestals are achievable, reducing the number of necessary components. The joists “tie together” the pedestals, providing increased lateral strength and stability to the entire frame.

Easy and Quick Installation

Designed with efficiency in mind, the substructure system is fast and simple to install. All necessary fixings and connectors are provided, ensuring a straightforward assembly process.

Versatility and Adaptability
