1 Cable TraysCable TraysTechnicalTechnicalInstructionsInstr uctions&&SpecificationsSpecificationsPro ducts Catalogue Objective and StructureThe company s main objective is the supply of quality products, with respect to: practical design increased durability easy and quick installation reasonable cost minimum delivery timeAt the same time, the correct design and selection of the Cable tray system is critical for the optimumperformance of the system, both in Technical and economical terms. For that reason, this catalogue isalso a guide to the best selection and use of Cable support products. This way, each project s specifi-cations will be fully met with a system of minimum purchase, installation and maintenance costs.

2 The first few pages provide some basic Technical Instructions for the correct selection of: corrosion resistance Cable tray support type dimensions of supports and Cable Trays material thickness and distance between supportsBy following the Instructions and the detailed product description of each product, engineers can easilyselect the correct item for each KoundourakisGeneral ManagerPage 2 GUARANTEEMETALLODOMI covers with limited guarantee of twe (2) years from the day of purchase for all theproducts manufactured Hot Dip Galvanized According to DIN EN ISO INSTRUCTIONSPage 3 Our products are classified according to their corrosion resistance level as made of pre-galvanized sheet.

3 The sheet metal is dipped in zinc bath at 450 C according to the EN ISO 10142 resulting zinc layer has an average thickness of 20 m. The next step is punching and bendingof the metal surfaces resulting from cutting and punching are also protected against corrosion (up to 2mmof sheet thickness) due to the formation of zinc : Dry-air, indoor made of mild steel sheet and then hot-dip : The mild steel sheet is punched and formed. The next step is hot-dip galvanizingaccording to the EN ISO 1461 standard. The resulting zinc thickness is about 60 m. Use: Indoor applications with high moisture or outdoor made of stainless : Stainless steel sheet is punched and formed.

4 Use: Special applications, food or chemical industries and seaside types of corrosion resistance can also be applied and offered: Products made of raw steel sheet, electro-galvanized Products made of mild steel sheet, hot-dip galvanized and epoxy powder spanThe life span of a zinc-coated material cannot be accurately predicted.

5 For example, large cross-section cables which are energy carriers release significant quantitiesof heat, therefore they need to be routed using Cable ladders in order to enable the air flow around , network, signal cables or even low power cables can be routed through Cable the cross section and the number of cables to be routed are known, the suitable Cable tray crosssection can be suggested selection process is the sum of Cable cross sections is result is multiplied by a factor of to take into account the random placement of thecables into the Cable new result is multiplied again with a minimum factor of to consider some extra free space in the Cable tray for possible additional cables to be routed through the Cable tray in the Cable tray cross section (width x height)

6 That will be selected must be equal to or greaterthan the result of the above mentioned order to facilitate calculations, the following table contains the dimensions of the most commonlyused cables. It must be noted however that the values in the table are approximate.
