The Panels

70% of the raised floors annually soldworldwide is with steel tray as most of thecurrent international regulations can be fulfilled atcompetitive prices only by using galvanized steel withhigh load capacity, lightness, calibration and fast production.GW Company developed a steel encapsulated panel with aninnovative design (European patent n. 1409812); its vertical and re-entrantstructural reinforcement along the whole perimeter has been positioned wherethe static tension, due to loads, is higher. Such design provides far higher loadcapacity than all the other internationally most-sold panels.The two steel plates are glued to both sides of the core and clinched by a 250 tmechanical press, without any kind of welding; it was this idea to give birthto the fully automatic production line, at present one of the most modern inthe world.

The GW steel encapsulatedpanels offer exclusive advantages in

comparison to the traditional panels inchipboard or calcium sulphate

· Higher Load CapacityHigh mechanical characteristics due to the vertical and

reentrant structural reinforcement along the whole perimeter· Maximum use of the spaces among the floor ground

and the raised access floorUsually installed using pedestals only, without stringers.

· Better and Easier Building Site OperationUsually installed at the end of external side operations

Can be used as a working platformCan be finished at the conclusion of all the building site operations

· Naturally thought for loose-lay panel finishes· Completely suitable for traditional glued panel finishes

MainFeatures

Raised Access Floors

Flexible spaceModern office environments require flexibility and accessibility. Raised accessflooring is used to meet these requirements by creating a plenum space wherehigh concentrations of power/data cabling and other mechanical services canbe concealed under the walking surface. These subfloor services remain easilyaccessible due to the modular design of the raised access floor system, thus pro-viding flexibility for quick and easy layout changes, installation of new equipmentor repair and maintenance works.

Product applicationThe evolution in the raised floor industry has widened the application rangefrom the general computer areas to bank counters, expo stands, shopping cen-ters, hotel halls, pubs, hospitals, surgeries, industrial production sites, data pro-cessing centers, clean rooms, recording studios, casinos, dance floors stages,bowling alleys, museums and in the restoration of historical sites. Nowadaysraised floors can be also used in modern houses where domestic innovationsneed a continuous evolution of layout.

European Certification EN 12825

This European Standard, approved by CEN, got the status of a National Standard so that within 5 years from its approval any project in CEE wouldhave to comply with it.From February 2007 this standard is the only one that specifies the characteristics and performance requirements of raised access floors for internalfitting out of buildings, providing full access to the services in the plenum.It is applicable to modular, factory made flooring elements, comprising panels and pedestals, and defines their methods of testing and measurements.

The ultimate load is the main criterion for classification.This is the value of component failure during a specific ultimate load test procedure.The elements, when subjected to the test procedure, shall meet the following criteria:

a) Before the element collapses, it shall have withstood the relevant ultimate load for its class, given in table 1.b) When the load applied is equivalent to the working load, which is the ultimate load divided by a safety factor, the deflection shall not exceedthe value of table 2.

GW Company usually applies Safety Factor 2 and 2,5 mm of deflection.

Pedestal vertical load bearing capacityThe substructure has to support 4 times the working load of the system tested.The pedestal may not become distorted or damaged.

Dimensional deviationsThe panels of a raised access floor shall be manufactured with dimensions whichenable their interchangeability. Deviations of dimensions shall not exceed thevalues given in table 3 for one of the appropriate classes.

Reaction to fireWhere required, the raised access floor shall be classified for its reaction to fireaccording to prEN 13501-1. Where the procedure allows to test a representativeportion of the raised access floor, this shall be done in accordance with the re-quirements of the method (i.e. for the positioning of joints).Where it’s not possible, testing and classification shall be evaluated on theperformance of each component and/or materials of the raised access floor. Inthis case, results for the raised access floor shall be based on the reaction tofire classification of each component and/or material. Where materials or com-ponents may be classified, without testing, in reaction to fire Class A1, it shallbe declared in advance.

Electrostatic conductivity The element shall comply with EN 1081, EN 1815 and HD 384.6.61, where re-levant.

The choice of the suitable raised access floor system depends firstly on the in-tended use, as for office spaces, housing or technical rooms.

Panels and floor coveringsThe first criterion of selection is the working load; it is advisable to preliminarycheck the comparison table (pag. 12, 13 and 14). The load classes from 3to 5 efficiently fits most of functional requirements.The load class 2 is more suitable to non-permanent loads whilst class 6 is nor-mally used for areas with specific and extremely high load requirements. At thesame time, it is necessary to choose the most suitable finishes for the intendeduse, to be compatible with the desired type of panel.In general, within the wide range of choice, it is advisable to use stone or ce-ramic finishes in high traffic areas, such as corridors, lift entrances and halls;moreover these finishes can also be applied in all those office or housing spaceswith an a high profile appearance. Considering the nature of these materials, veryresistant to abrasion but also very fragile in case of excessive deflection of thepanels, the use of the steel encapsulated panels grants an higher resistance todeflection, avoiding snapping or breaking of the covering surface.Resilient materials (PVC, rubber, linoleum) can be used for almost all opera-tional office spaces.About wood, its extremely natural beauty of the essences have to be preservedby a careful use, particularly focusing on humidity control and maintenance, intotal absence of water. Given these premises, wood coverings can be used in anyspace, with the only obvious exclusion of technical rooms. The coverings withmulti-layered parquet are the most suitable to be glued to the steel of theencapsulated panels.It’s possible to use the bare GW panels as walking surface, along with possiblevariations in stainless steel, to fit specific minimalist or hi-tech aesthetic andarchitectural choices. It can be successfully applied with no particular restrictionsin modern offices, show-rooms, display areas and shops (see the photo 1).Last element to evaluate in the panel/covering matching process is the flexibilityof use along with the optimal site management feature offered by the magneticloose-laid tiles, exclusive of GW Company. In this case, the bare faced steel encapsulated floor can be first installed on site,leaving the option to loose-lay the desired final covering at a later stage, withoutusing adhesives, thanks to the magnetic layer of the tiles. The final coverings/fin-ishes will so avoid all the potential post-installation damages caused by workingoperations during the building process of the site. Furthermore the choice of loose-laid Janus covering can be customized area by area, even at different times andwithout interfering or operating on the main steel encapsulated raised accessfloor.The total flexibility also involves format and design, allowing future varia-tions at low costs. The magnetic loose-laid tiles is perfect to developers wishingto offer, in business or commercial centers, finishing solutions that are tailored tothe end-users or easy-to-change destination of use.

Guide to the choice

SubstructuresThe type of substructure to match the chosen panel/covering mainly dependon the height of the finished floor; for floor heights up to 400 mm pedestals(ST1 or ST1 Gold) can be used with all the panels from the GW series; in caseof heights over 400 mm it is always advisable to use stringers (substructuretype ST2 – ST3 Standard or Gold) to ensure the correct lateral stability.As an alternative to stringers or to grant a better protection of the subfloorplenum, a “corner lock” system can be put in place, with the panels screwedto the pedestals heads.

Acoustic requirementsDensity and weight of the materials determine significant variations ofthe acoustic properties. Encapsulated raised floor systems, especially thosewith calcium sulphate core, have high soundproofing features. Care mustalso be taken in the choice of the final floor covering (textile, resilient,stone or metallic) as it can determine variations of the acoustic perfor-mances.Due to the complexity of this subject, it is recommended, if in doubt, to con-sult our Technical Department.

Antistaticity and conductivityProblems due to electrostatic charges generated on the floor surface can beavoided by an appropriate choice of the materials. In particular, antistaticand/or conductive coverings (laminates, textiles, pvc, etc.) with electrical re-sistance ranging between 106 and 1010 Ohms, can be chosen depending onthe intended use of the area, applied with conductive adhesive.

Resistance to humidityRaised access floors can notoriously be sensitive to sudden changes of tem-perature or to high relative humidity rates.In case, for instance, of constructions like high raise buildings/ skyscrapers,where many months can pass before the air conditioning is fully functioning,or in geographical areas like the Middle or Far East, characterized by high tem-peratures and humidity, GW panels are the perfect choice, both with chip-board or especially with calcium sulphate core. Furthermore, thanks also tothe micro area for dilation, GW panels are the best performing panels in theworldwide market.

Special finishesParticular aesthetic requirements can make sometimes difficult to adopt thebest suitable covering materials.One of the features that characterizes GW panels is indeed the high level ofexperience in proposing a wide range of special finishing materials.

GW series is also available with a “Corner Lock” option, a system

which allows the fastening of each panel to the pedestals heads

by means of self tapping screws.

The system offers:

- maximum rigidity and stability even at higher finished floor

heights, without the need for additional stringers.

- protection from unauthorised access to the underfloor area.

- maintenance of structural properties even in case of special ser-

vicing/alterations of the fixtures and fittings in the underfloor area.

The drilling on the 4 corners is made by CNC machines assuring

the best possible calibration and interchangeability

of every single element.

Installation and Maintenance

To optimise the installation of raised access floors it is advisable to followthese important directions:

StorageImmediately after offloading, the materials must be stored for at least 24 hoursin a dry area, closed to weather conditions preferably in an environment attemperatures ranging between 5° and 35° and relative humidity between40% and 70%.

Site preparationIn case of newly constructed buildings, the screed / subfloor must be free ofmoisture and properly cured (for at least 2 months if made of traditional con-crete).The screed must be free of debris or dirt and sufficiently flat, treated with antidust sealants.Windows and door frames must be in place and all other trades must have fi-nished their work (i.e. installation of ceilings, ducts/piping, electrical fixtures,plastering, cladding, curtain walling, etc.) and removed their equipments atleast 24 hours prior to starting the raised access floor installation.Services must be finished before the installation starts and must be situatedfollowing the designed positioning in the pedestal grid. The grid must havepreviously been traced on the subfloor with paint so that ductworks, piping,cabling or obstructions do not interfere with the raised access floor under-structure pedestals.Services (ductworks etc.) should not be placed in close vicinity of the perimeterwalls or columns in the room. The layout of the above mentioned grid mustallow, where possible, for perimeter cut panels at least 15/18 cm wide for sta-bility and aesthetic reasons.It is good practice to check with a rotating laser that doors thresholds and/orother traditional floors areas are all levelled at the same height.

InstallationIt is important to determine carefully the staring point for the installation takingas reference point of the structure two orthogonal axes and laying out the controllines verifying their accuracy with the Pythagorean Theorem (see pic. 1). It is ad-visable to have the starting point checked on plans by the Architects, Main Con-tractors or the floor manufacturers. While the installation proceeds it is veryimportant to keep checking the levelling of the system by means of spirit levels,levelling bars or rotating laser devices.Assembling or disassembling of partial areas of the system must be carriedout only by specialised personnel.Moving heavy equipments (safes, heavy filing cabinets, etc.) must be carried

out by using spreader plates or special trolleys to spread the weight onto theraised access floor system and at the same time avoiding damaging the floorcoverings.It is mandatory to attach the pedestals to the subfloor by means of adequateadhesive; pedestrian traffic can only be allowed after at least 12 hours frominstallation.Installation of floor accessories / ancillaries i.e. electrical and data outletboxes should be done following the layout specified in the Contractor’s shopdrawing. The installation will be completed with all the required accessories(see pag. 16)

Floor maintenanceCleaning should be done only by means of vacuuming or using specific equip-ments for this purpose. Water must not be used directly on the floor surfaceas this might cause delamination or debonding of the panel covering andeventually swelling of the panel itself, especially when not using steel encap-sulated chipboard core panels.Washing of the surface can be carried out only by strictly following the direc-tions given in the maintenance technical data sheets or after consulting ourTechnicians.The cleaning methods vary according to the chosen covering materials.On some resilient coverings (linoleum, PVC), wax treatments should be appliedto optimise the day-to-day and scheduled cleaning operations. Our TechnicalDepartment will be pleased to be of assistance for any clarification required.The raised access floor system is composed of removable panels, for structuralsafety and for the safety of its users, dismantling or replacement of panels(i.e. when installing new services in the floor cavity) should be carried out bylifting only alternate panels at a time to maintain the correct panels alignment.
