Problems related to the incompatibility between traditional building structures, conceived as to remain unaltered in time, and technical wiring, which need to be changed continously and adapted to user new necessities, are extremely important in buildings provided with high technological environments. In the beginning, access floors had been projected only to solve problems of plant engineering in data processing centres. Today, access floors are the best solution for many other projects where technical flexibility is required.

Bridging profiles are used when a raised floor must be installed over ducts, channels, conduits, or holes of large sizes.
These bridging profiles enable to suppress one or several pedestals.

This all steel pedestal fully complies with the heavy grade requirements of the PSA MOB PF2 PS/SPU specification and is used for finished floor heights from 600mm to 1200mm. The pedestal design utilises a 90mm diameter head which allows the use of standard plastic head caps. The baseplate is 120 mm square and includes provision for the use of mechanical fixing to the sub-floor in addition to the use of pedestal adhesive if required. The pedestal head design allows for the use of snap-on and bolt-on stringers if required.

System Description
The structural stringer bar is press formed from 1.20mm galvanised steel. The tang at each end of the stringer positively locates through the pedestal head and can be mechanically fixed if required. The structural stringercompliments the MaxspanHeavy grade panel enhancing the system to Extra Heavy grade.

System Description
Each pedestal consists of a flat steel base plate 100mm x 100mm x 2.5mm thick. The base plate has four 6mm holes near each corner. The holes are on the diagonal 11mm in from the corners. A 25.4mm outside diameter by normally 20mm inside diameter steel tube 25.4mm high is spot welded to the centre of the base plate A threaded steel stud with a thread diameter of 19.8mm is pressed into the base plate tube. A 15.5mm steel nut fits onto the free end of the steel stud. The head consists of a circular steel plate 89mm outside diameter with a 31mm inside diameter hole at the centre, formed by pressing down a circular flanged lip 12mm deep in it. The head is 2mm thick and has four 5.8mm holes spaced evenly around it on a 65mm PCD, 10mm in from the circumference. The last 6mm outer edge of the circular plate is profiled downwards slightly and the circumference truncated slightly at four points evenly spaced around the circumference. A steel tube 70mm long x 25.4mm outside diameter x 20.3mm inside diameter is swaged over the last 25mm of one end such that the free end has an outside diameter of 38.5mm.

Structure composed of Base resting on the slab floor and Head which the panel rests on.
Base: round, 93 mm in diameter and 1.5 mm thick, specially reinforced with strengthening ribs to give it structural rigidity and predisposed with holes for attachment to the slab floor.
The base is moulded for attachment to a shaft measuring 20x2 mm of variable height, pressure-fixed to the base by means of press-fitting of the shaft itself.
Head: square-shaped 80x80 mm and 2.5 mm thick, this is cold-formed and predisposed with a socket to receive the gasket for the head.
Stringers: absent
Adjustment system: At the centre of the head the screw + nut group allows variation of the height of the entire structure using the micrometric, anti-back-off mechanism so as to achieve the final height.

Structure composed of Base resting on the slab floor and Head which the stringers rest on.
Base: with plate of 95 mm diameter 1.5 mm thick, suitably moulded for attachment with a non-grooved, cold galvanized shaft measuring 20x2 mm.
Head: supports the stringers by means of a square plate 110x110 mm 3 mm thick with lateral screws M5x10 for attachment to the stringers. The edge of the plate is suitably shaped for insertion of the stringers.
Stringers: with connective and load-bearing functions, these are rectangular section bars of 50x25 mm, 1 mm thick; available in the following lengths: 2400 mm/1800 mm/550 mm. The stringers are fitted with self-adhesive anti-static gaskets designed for coupling with the panels of the raised floor.
Adjustment system: at the centre of the plate a tension rod is screwed on with relative anti-back-off nut providing micrometric adjustment of the final height.

The Freeway access floor is elevated flooring formed by 600 x 600-mm steel panels with cold-drawn corners and cement cores installed by positive positioning onto height-adjustable, metal pedestals fixed to the sub-floor. Recommended for use in buildings in which easy plenum access is required.
The panels are extremely easy to remove thanks to the screwless, positive positioning system making this floor highly suitable for buildings in which frequent access to the installations is required.
Can be adapted to any type of space given that the steel/cement combination provides the panels with outstanding performance under all kinds of load %u2014static, dynamic and impact.
Pleasant for users given that the density of the materials used, the weight of the panels and the precise fit make for a floor as silent as an original concrete floor.
Meets all of the requirements of sustainable architecture: unalterable regardless of conditions of humidity and temperature, thereby making installation prior to building or wall completion possible. The panels can also be changed around and even reused at different sites.
