COSMEC Ltd. a leading manufacturer of rigid and flexible metal pipes, fittings, boxes and accessories for cable protection and more.
Metallic materials are suitable for factories, feed stores, warehouses of paper records or woodworking shops where plastic casing is subject to damage by rodents and can not guarantee adequate protection.
An appropriate electrical installation is not only designed to protect against a fire, but also to prevent its spread, and spread of toxic fumes or gases. Given this fundamental security requirement, it is clear that in public places (for example, discos, theaters, shopping centers and underground parking areas) metallic materials are preferred because there is no danger of ignition and are completely immune to external forces.
For example, an installation of PVC exposed to sunlight, the plastic loses about 20% of its mechanical properties during the first year, making it inadequate to protect the wire that was intended. Another example of the use of metallic material which does not lead to a rapid deterioration of the facility can be found in public parking areas in which pipes are positioned at lower heights where they are subject to vandalism.
