Electrolytically galvanized and bichromated cable trays (ZB)

EZ-ZBThis is a galvanic method, whereby by means of electrolysis a thin layer of zinc is applied to the steel wire. The process is carried out in accordance with EN12329: 2000. The applied zinc layer varies between 8 to 12 μm. This is followed by a treatment with chromium salts that improve the corrosion resistance. Mesh wire trays electrolytically galvanized and bichromated are exclusively intended for use in heated and dry rooms with negligible amounts of air pollution.

Hot galvanized cable trays (HD)

HDThis galvanizing process is also called immersion galvanizing or hot galvanizing. The application of the zinc layer is effected by means of immersion for a short time of pre-fabricated products in a liquid zinc bath. The applied zinc layer depends on the material thickness, but is approximately 70 μm for wire channels. The process is carried out in accordance with NEN-EN ISO 1461. Screws and nuts are galvanized according to EN-ISO 10684. Hot-dip galvanizing is the galvanisation method for products that are assembled by means of welding (such as parts for suspension of cable carriers). However, wire trenches can also be galvanized in this manner after manufacture. Due to the rather large zinc layer thickness, this galvanisation method is very suitable for cable supports, which are mounted in the open air. Even in aggressive environments in the industry, hot-dip galvanized products are often in place.

 

EZ1000 cable trays (RoofSupport Click)

EZ1000 is a preservation of metal similar to electrogalvanizing. However with other added components. EZ-ZBThis ensures that EZ1000 has a higher degree of protection than hot-dip galvanized steel. The degree of protection is almost equal to RVS304. Stainless steel achieves class C9 according to EN-61537, while EZ1000 achieves class C8+. This is based on salt spray tests in accordance with EN-ISO 9227.

 

 

Stainless steel cable trays (AISI 304 en 316) *

inoxIt concerns carbon steel learned with chromium, nickel, magnesium and molybdenum. The most well-known stainless steels are AISI 304 (18/8) and AISI 316. Contrary to popular belief, stainless steels are also subject to corrosion, but their behavior is generally better when handled correctly. that of any other protective coating. Their specific behavior is due to the fact that, in an oxidizing environment, chromium and nickel spontaneously generate a layer of chromium oxide, a layer that prevents subsequent oxidation. This layer is very fragile and can be destroyed by denting, machining, soldering, …
Stainless steel easily loses its properties when processed with tools that are also used with other types of steel. In that case the protective film must be regenerated by a chemical
incorporation process.

 

* Stainless steel wire mesh cable trays normally have a lead time of 4 – 6 weeks. Please contact our sales team for the current lead time.

 

Magnelis

Conduct uses Magnelis for the PVshelter.
The roof, brace plates and ballast supports are made of this material.

Magnelis has a special coating consisting of:
93.5% zinc
3.5% aluminum
3% magnesium
The magnesium ensures the formation of a stable, durable coating on the entire surface. It also guarantees much more effective protection against corrosion than coatings with a lower magnesium content.

Exceptional resistance to corrosion
Magnelis steel offers exceptional resistance to corrosion, much more so than conventional hot-dip galvanized steel. In an ammonium-containing environment, corrosion has seven times less impact with a Magnelis coating. Fog tests were also conducted where no rust was observed on the Magnelis steel.

Self-healing effect
Magnelis offers the same cathodic protection as that of a traditional metal protective coating. This in combination with the formation of a magnesium film increases the corrosion resistance of the segments. The nature of this film can vary depending on the environment and its properties also change depending on the content of aluminium and magnesium.
