Bolts, Setscrews, Coach Bolts & Machine Screws.The system is complemented by the use of a black colour zinc spray that is suitable for the protection and aesthetic improvement of cut rods and possible damage caused during installation. This system offers the same corrosion resistance of Class C8 for everything, improving the performance of the system against aggressive environments and enhancing the performance of a hot dip galvanized finish, where accessories and brackets do not reach this classification. Rejiband® BLACK C8, product range includes a complete catalogue of accessories and supports, providing a high corrosion resistance and a better visual aspect to the whole installation. The BLACK C8 coating is manufactured in a process which significantly reduces energy consumption and waste generation over other coatings which consume more resources like hot dip galvanised. These features retain the properties of flexibility and the forming of accessories with rejiband®, bends, level changes, in any format. It is possible to bend the the tray without causing any damage to the finish. 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. Increased capacity for selfhealing, or self-repairing, of the protective layer The most appropriate coating for Data CentresīLACK 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 Centres. This feature allows bonding to other exposed conductive elements and, in case of a fault, the evacuation of electrical currents to the earth. 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. Black colour provides excellent aesthetics which are suitable for decorative applications, commercial facilities, false ceilings, etc.No irregularities or areas with reduced thickness.The smooth finish is much more aesthetic than that of 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. 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. Where necessary, cable tray systems and cable ladder systems may be used for the division or arrangement of cables into groups.ĭuration (h) Salt Spray Chamber Chamber Test – acc. This International Standard specifies requirements and tests for cable tray systems and cable ladder systems intended for the support and accommodation of cables and possibly other electrical equipment in electrical and/or communication systems installations. 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. High Corrosion Resistanceĭemonstrated 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. Pemsa has developed a high resistance coating for rejiband® wire mesh tray which provides an excellent resistance to corrosion in wet and aggressive environments.
