W ith different types of solution and materials available, choosing the correct cable management for a particular building or application is not always simple. While PVC-U is often the go-to because it is cost-effective, easy to install and versatile, for some applications like; steel, aluminium or Glass, Reinforced Polyester (GRP) can offer additional benefits. To select the most suitable product, the requirements of the building users, the environmental conditions and installation factors must all be considered. Mechanical strength Often one of the most basic and ultimately important considerations is ensuring the cable management system can withstand the level of wear it will likely be exposed to. Dado trunking, due to where it is mounted within the room, may receive accidental heavy impacts, especially in busy environments. For example; where equipment or materials are moved frequently, such as inwarehouse environments, the trunking can be damaged if it is not sufficiently robust. In these situations, a steel or aluminium systemmay bemost suitable. While the initial cost is often higher, the greater mechanical strength that ametal systemoffers can minimise the need for additional maintenance and replacement of damaged sections. Antimicrobial systems For certain environments, such as hospitals and other healthcare facilities, ensuring maximum hygiene and protecting those using the building is of the highest priority. As a surface mounted product that may be touched by many people, it is important to carefully consider the specification of trunking products. Cable management systems with advanced antimicrobial properties can help minimise the spread of germs and bacteria. There are a range of different antimicrobial agents. However, silver ion-based technology is one of the most effective forms of continual protection. The silver ion formulation can either be added to the PVC-U or ABS when it’s manufactured or applied to the surface post-production. ➜ Which cable management systemmaterials and applications are most suitable
