We have also attached data sheets for the options requested also. However the European NORM for Raised Access Floors does not require testing of the distributed load, however based on the loading characteristics of the options we have offered, a theoretical distributed load per m² of 30,000 N/m² is achieved.

 We make note that the number requested for distributed load is made in mm², and would draw your attention to this being an error because mm² is not an area defining distributed load. 

  The following is the selection of Crespi products for this application :-

  THE UNDERSTRUCTURE

 With reference to the request, we would firstly like to discuss the Crespi under structure selected for this application.

 We have selected two type of understsructure :-

 1.A)          Understructure for FFH of 170mm

 1.A.1) The MR10CT-BOLT under structure incorporates a three dimensional pedestal head, which is ribbed to increase strength, making it the strongest of its type on the market.

 1.A.2) The modular stringers selected for this application are of a closed rectangular section with dimensions 50 x 25x1mm. They are supplied with self extinguishing gaskets and bolts and nuts to secure to pedestal head.

  

1.B)          Understructure for FFH of 500mm

 1.B.1) The MR8H-BOLT under structure, in difference to all other manufacturers who produce flat pedestal heads, has a three dimensional head manufactured in die cast aluminium and is the most rigid available on the market, and in conjunction with stringers offers the highest level of structural rigidity at the height required.

 At the required height of 50CM, the pedestal base will require to be glued or screwed to the building slab for rigidity. Price of glue is included within pricing as an option.

 1.B.2) The modular stringers selected for this application are of a closed rectangular section with dimensions 50 x 25x1mm. They are supplied with self extinguishing gaskets and bolts and nuts to secure to pedestal head.

 

PLEASE SEE BELOW FULL DESCRIPTIONS

  1.A) UNDERSTRUCTURE  – MR10CT

 This understructure has been in production since 1984.

 Adjustable pedestal MR10CT is composed from a head and a tube manufactured with galvanized steel.

 The stamped head section is ribbed for rigidity, with three dimensional arms.

 The steel tube is fitted to the head for better strength.

  The pedestal bases are produced in galvanized steel with a threaded rod. They are supplied with a locking nut to secure the height.

MR10CT stringers are manufactured in stamped steel with Omega section and formed ribs to obtain a high moment of inertia.

 MR10CT stringers are inserted in the three dimensional arms of the head and can be fixed with bolts or screws.

 The stringers are available with the following sections:

- Ω 38 with dimensions of 38x25x1mm;

- Ω 27 with dimensions of 27x25x1mm;

- Ω 10 with tapered section;

- € 30 with rectangular section of 30x25x1mm;

- € 50 with rectangular section of 50x25x1mm.

- SELECTED FOR THIS APPLICATION

 Structure MR10CT can also have diagonal stringers in order to obtain a more rigid bracing (e. g., for seismic zone).

 All elements of MR10CT under structure have self extinguishing polyethylene gaskets.

  1.B) UNDERSTRUCTURE – MR8H

 This carrying structure has been in production since 1978 and today is still considered the best on the market.

 Adjustable pedestal MR8CT is composed from a three dimensional head with threaded tube manufactured from pressure die cast aluminum, and a steel threaded rod insert. The head section is ribbed diagonally to offer higher rigidity and support for the threaded bases. They are supplied with a locking nut to secure the height.

  The pedestal bases are produced in galvanized steel with a tube. They are supplied with a locking nut to secure the height.

MR8CT snap-on stringers are manufactured in stamped steel with Omega section and formed ribs to obtain a high moment of inertia.

 MR8CT stringers are inserted in the three dimensional arms of the head and can be fixed with bolts or screws.

 The stringers are available with the following sections:

- Ω 38 with dimensions of 38x25x1mm; - Ω 27 with dimensions of 27x25x1mm;

- Ω 10 with tapered section;

- € 30 with rectangular section of 30x25x1mm;

- € 50 with rectangular section of 50x25x1mm.

- SELECTED FOR THIS APPLICATION

 Structure MR8CT can also have diagonal stringers in order to obtain a more rigid bracing (e. g., for seismic zone).

 All elements of MR8CT understructure have self extinguishing polyethylene gaskets.

  GENERAL NOTE FOR UNDERSTRUCTURES

 The galvanization of the steel components is realized according the EEC directives 2002/95 –2005/63 – 2005/438 – 2005/673 concerning the restriction to use of harmful substances.

 THE MODULAR PANELS

 2.A)     For this application we have selected a “high resistance” modular panel with a Structural core made with Calcium Sulphate, “Knauf Integral KG” original, certified ISO 9001 / fire reaction class ZERO, according norms UNI ISO 1182/95 & A1fl  according to UNI EN 13501/ fire resistance in excess of F60 (60 minutes) in accordance with DIN 4102 part 2 / thickness 36 mm.

2.B)     The under covering of the modular panels will be in aluminium foil.

2.C)     The upper coverings for the modular panels are selected of firstly a range of High Pressure Laminate (non conductive) with a thickness of 0,9mm.

 Secondly from the TARKETT, TORO SC range of static conductive PVC (electrical resistance acc. EN 1081 --- R1 5 x 104 ≤ R ≤ 10--- R2 5 x 104 ≤ R ≤ 106), with a thickness of 2mm.

 2.D)     The border of the panel is manufactured in a shock resistant, self extinguishing ABS material.

 We trust the attached information fully covers your current requirements, and look forward to further communication in the near future.

 Should you have any queries, or require any further information or clarification, please do not hesitate to contact us.
