Pemsa Rejiband BLACK C8 - THE most suitable system for Data Centers.

Back to Blog Listing

Pemsa has developed a high resistance coating for rejiband® wire mesh tray which provides an excellent resistance to corrosion in wet and aggressive environments. It presents the following advantages.

1. High Corrosion Resistance

Demonstrated with more than 1000 hours in the neutral salt spray tests and obtained through a new manufacturing process that improves both the barrier effect against the aggressive media and the ability of self healing in damaged areas. With the result obtained in the neutral salt spray test, more than 850 hours, the corrosion resistance is classified as Class 8, according to Table 9 of the current standard BS EN 61537 trays.

rejiband® BLACK C8 has obtained the AENOR N Marking (Spanish Association for Standardization and Certification) and the certification IECEE CB Scheme of IEC (International Electrotechnical Commission), garanting the Class C8 of resistance against corrosion, with more than 1000 hours on the Salt Spray Test

2. Better Features than Hot Dip Galvanised.

Hot dip galvanised normally ranges from between 45 to 70 microns mean coating thickness, so it should be Class 5, 6, or 7, having a lower corrosion resistance than BLACK C8

3. Aesthetic appearance.

The smooth finish is much more aesthetic than that of hot dip galvanised.

  • No sharp edges or ends.
  • No irregularities or areas with reduced thickness.
  • Black colour provides excellent aesthetics which are suitable for decorative applications, commercial facilities, false ceilings, etc

4. Electrical continuity

This coating maintains the electrical continuity of rejiband®, complying with the requirements of BS EN 61537 standard for cable tray system with electrical continuity characteristics. This feature allows bonding to other exposed conductive elements and, in case of a fault, the evacuation of electrical currents to the earth.

5. The most appropriate coating for Data Centers.

BLACK C8 coating avoids the emergence of the phenomenon of Zinc Whiskers, or loosening of filaments of zinc, which can be a serious problem within the electronics of clean rooms in Data Processing Centers

6. Increased capacity for selfhealing, or self-repairing, of the protective layer.

The characteristics of self-healing, or self regeneration, on scratches, minor defects or in the cutting of the wire, are remarkably better than that of the zinc

7. Excellent ductility.

It is possible to bend the the tray without causing any damage to the finish. These features retain the properties of flexibility and the forming of accessories with rejiband®, bends, level changes, in any format
