Floor panels form the visible walking surface of the raised floor system. They are designed to withstand different load capacities while providing easy access to the underfloor space whenever maintenance or future modifications are required.

Depending on the project requirements, floor panels can be manufactured from different core materials, including:

• Steel Cementitious Panels

• Calcium Sulphate Panels

• High-Density Wood Core Panels

These panels can be finished with various surface materials, such as:

• Carpet Tiles

• Vinyl Flooring (PVC or LVT)

• High Pressure Laminate (HPL)

• Ceramic Tiles

• Natural Stone

• Rubber Flooring

The ideal panel depends on several factors, including load requirements, fire resistance, acoustic performance, moisture resistance, and interior design preferences.

Pedestals are the primary structural supports of the raised floor system. They are anchored to the concrete slab and adjusted to the required height to create the underfloor void.

High-quality pedestals provide:

• Excellent structural stability

• Accurate height adjustment

• High load-bearing capacity

• Long-term durability

• Corrosion resistance

Pedestal heights vary according to the amount of building services that need to pass beneath the floor.

Stringers are horizontal steel members that connect adjacent pedestals, increasing the rigidity and stability of the flooring system.

Although some low-height systems can operate without stringers, they are highly recommended for projects requiring:

• Higher structural performance

• Heavy rolling loads

• Reduced floor vibration

• Increased lateral stability

The floor finish is selected according to the building's functional and aesthetic requirements.

Common finishing options include:
