Question 1

What flooring does a data centre need?

Accepted Answer

Different floors for different rooms: conductive epoxy such as Rayson StaticGuard CX90, earthed and tested, in the ESD-protected rooms around the data hall; self-levelling LevelShield SL120 in loading bays and plant rooms outside the ESD programme; a textured deck system in car parks; a reflective membrane on roofs.

Question 2

Which rooms need an ESD floor?

Accepted Answer

The rooms the facility’s ESD programme names, usually those around the data hall: electrical and switch rooms, UPS and battery rooms, staging and build rooms, and the loading areas where servers leave their packaging. StaticGuard CX90 is conductive through its whole body, 10⁴ to 10⁶ ohms on average, so the static path does not wear away with the surface. The ESD targets come from the facility’s own programme, often written to IEC 61340-5-1 or ANSI/ESD S20.20; the floor is specified and tested against them.

Question 3

Why does the earthing matter?

Accepted Answer

A conductive floor is useless without a path to ground. CX90 is laid over planned earthing points, its thickness kept within 1.0 to 1.5 mm because a thicker floor conducts less, and its resistance measured after cure and recorded for the facility. The earthing layout is agreed with the M&E engineer before the floor goes down; the data sheet keeps heavy traffic off for 72 hours and allows about seven days for full cure before testing.

Question 4

What about the plant rooms and loading bays?

Accepted Answer

Where the ESD programme does not reach them, they take the weight instead: generators, chillers, pallet trucks and deliveries. LevelShield SL120 self-levelling epoxy, which lists plant rooms, loading bays and storage areas, gives them a seamless, hard-wearing floor with medium to heavy chemical resistance. Where the programme does include them, they take CX90 like the other ESD rooms. Car parks take the FloorGuard R50 broadcast system, and the roofs SealForce RC40, a polyurea membrane with certified cool-roof reflectance.

Question 5

Can Rayson support the consultant’s material approval?

Accepted Answer

Yes. Rayson supplies the published data sheets, the build-up for each room and the application guidance for the consultant’s and main contractor’s submissions, and the Rayson-authorised applicator quotes and installs, contracting with the main contractor or the owner. Rayson makes the materials and warrants them; the applicator warrants its workmanship. Both are named in the submission, so the consultant knows who answers for what.

Question 6

What does data centre flooring cost in Malaysia?

Accepted Answer

Per square foot, quoted room by room after a review of the drawings and the site. Five things decide it: the area of each room, the system for each, the ESD testing and earthing details, the state of the slab, and the construction programme the main contractor sets. Rayson publishes no price list; contractors with their own crews can buy the systems direct.

Question 7

Does CX90 go in the data hall itself?

Accepted Answer

Usually not. A data hall with a raised access floor carries its static path through the raised floor, and the slab beneath is sealed, conductive where the design asks for it. CX90 is for the ESD rooms built on the slab around the hall; the specification sets out which rooms get which.

Question 8

Do you work on data centres outside Johor?

Accepted Answer

Yes. Rayson-authorised applicators work in Johor, Kuala Lumpur and the Klang Valley, and Penang; materials and data sheets are supplied nationwide for contractors with their own crews.

Question 9

Who gives the warranty?

Accepted Answer

Rayson warrants the materials as their maker; the Rayson-authorised applicator that lays the floor warrants its workmanship. Both are written into the quotation.

Compared on	Rayson system	Build	Why it fits
ESD rooms: switch, UPS and battery rooms, staging and build	StaticGuard CX90 conductive epoxy	1.0 to 1.5 mm, over earthing points	Conductive through its body, 10⁴ to 10⁶ ohms on average
