Raised Access Floor Understructure

RAISED ACCESS FLOOR - Understructure

“ALTAIR offers two types of understructure systems to cater for all heights, load performance requirements, and applications. All ALTAIR panels are interchangeable within the two understructure systems. The available finished floor height ranges from 75mm to 1800mm.”

The Cross-Head System

Utilizing a unique steel head that offers positive location of the panel corners onto the pedestal head, the Cross-Head system is recommended for areas of low finished floor height where extensive sub-floor services need to be installed. The stringer-less Cross-Head system offers the same ease of installation and maintenance, as well as increased unobstructed access to all sub-floor services. Electrical continuity and quiet underfoot performance are achieved with the use of a black conductive pvc gasket placed between the panels and the understructure head.

The main characteristics of ALTAIR understructure systems are structural strength. Both systems made of electro-galvanized steel and / or die-cast aluminium and are corrosion resistant in conditions of up to 95% RH. For extreme loading and climate conditions, please consult with ALTAIR for further technical details.

The Cross-Head system is ideal for general office and light duty applications with finished floor heights not exceeding 300mm. A specialty variation of the Cross-Head system allows for finished floor heights as low as 60mm.

The Stringer Grid System

Used in all applications, the Stringer Grid system is especially recommended for greater finished floor heights and heavy duty applications. Stringers are mechanically fastened onto the pedestal head thus providing a monolithic frame into which the panels are inserted. For further strength, bare panels may also be mechanically fastened onto the pedestal heads. This system ensures improved rigidity and lateral stability, as well as a superior underfoot feel. Panels are easily interchangeable within each stringer frame without the need for any alterations in the system.
