Monitor enclosures is available in different materials; learn why the different metals are used.
Commonly an LCD enclosure is produced from mild steel and powder coated to produce the relevant protection for outdoor digital signage, here the enclosures will be subjected to all kinds of weather from rain, snow, sleet and high temperatures, so make certain the housing you choose for outdoor digital signage protection has been hot dipped in zinc to prevent corrosion.
Monitor enclosures - Why Hot dipped?
If the Lcd enclosures is not hot dipped in a zinc compound, this compound forms a galvanised coat on the base metal that stops from rust attacking the steel. Then the steel LCD enclosure is then powder coated, the reason for this method is that if for some reason such as a vandal or hooligan attempts to harm the casing and chips the top coat of paint, the base material is still protected by the zinc coating, otherwise the base material will start to rust and the case ultimately will have to be replaced before it should.
So next time you are looking for a metal LCD enclosure, ask them if it is hot dipped and get them to give you addition data, if they have to email you later, they obviously do not know their item and more than likely will not hot dip the cabinet.
Stainless steel LCD enclosure.
Now in some purposes, customers require a stainless steel unit, this could be in a food setting or just used to show factory data systems, and the entire production area is washed down at the end of every working day.
Stainless steel substance is available in three categories Ferritic, Austenitic and Martensitic, these contain option compounds and there is only one that has the most Chromium (this is a corrosion inhibitor), so ask any potential what material their stainless steel is and if they do really make them they will know right away.
Even though they are several LCD enclosure producers who buy in materials from third world suppliers, getting the lowest priced item possible and assemble them, the problem with this is they will have no control over the material used, so you have no idea and they cannot guarantee what material the enclosure will be made from.
So ask for test certificates for the Lcd monitor enclosures was made from, so that you cans ee the original of the metal and safeguard your investment.
