Covers

Zekan covers are made of polyurethane resin reinforced by glass fibres.

Covers meet the highest demands on utility features, aesthetics and handling. They are characterized by low weight and high strength. They do not corrode, thus long service life without maintenance is ensured.

Dural frame can be installed in all types of surfaces including asphalt, where it can withstand up to 300 ° C during laying. By following the installation procedure, the Zekan covers together with the frames meet the degree of protection IP 45. The standard cover design is with the ZEKAN logo and other references to the CWS company, however, we can add custom logo and the RAL color scale on request.

Massive frames for ZEKAN covers have been over sized so they can be used with covers even under the most demanding conditions. The frames are simply connected by a verified system of fasteners at 8 points and with the possibility of fixation by the building binder to ensure the immovability of the joint. The frame design allows the cover assemblies to be customized from the smallest solution with lightness of 335 x 600 with the top limit not limited and it depends only on the specification of the installation.

Covers are not of interest to thieves. They are suitable for chemical and food processing operations, very resistant to the effects of petroleum substances, 10% acids and lyes. The material for the production of covers is self-extinguishing, dimensionally stable, with high surface hardness, hygienically safe, insulating, non-magnetic. The covers can also be machined with conventional tools for metals.

Lockability of the covers is designed in a standard design using a metric thread bolt and a threaded sleeve mounted in the body of the chamber. It is possible to choose a classic M10 screw with hexagon head or SECURITY screws of TORX type.

Covers for paving

Composite covers in the basic load classes are also used for the requirements to unify the cover design when fitting in the pavement.

The higher version of the perimeter frame is used to match the stainless steel tubs, which can be paved with up to 10 cm tiles. In the case of lower paving, such paving is laid on a layer of inert material to the required height.

LOADABILITY OF ZEKAN COMPACT COVERS

The load distribution of covers and related structures is governed by the EN 124 standard which distinguishes 6 load classes marked A to F. The ZEKAN cable chamber system allows the use of the 4 most common load classes A 15 to D 400.

The suitability for use of individual types is described by the above-mentioned standard. The choice of the given load class is to a certain extent the responsibility of the responsible designer depending on the specific conditions of the cable shaft location. The following illustration is only for a basic orientation.

 Advanteges of composite covers:

• people do not steal them
• low weight
• shape and dimensional variability
• strength and rigidity of the product
• self-extinguishing
• colour version according to RAL scale
• choice of surface - concrete imitation, high gloss or matt component
• surface hardness
• hygienic safety
• thermal insulartor
• non-magnetic
• chemically and mechanilcally durabe
• low maintenence costs
• weather proof
• the pissibility of machining with ordinary tools
