Lcd monitor enclosures is available in various materials; understand why the different metals are used.
Ordinarily an LCD enclosure is built from mild steel and powder coated to supply the related protection for digital outdoor signage, here the enclosure will be subjected to all kinds of weather from rain, snow, sleet and high temperatures, so make sure the casing you choose for outdoor digital signage protection has been hot dipped in zinc to stop rusting.
LCD enclosure - Why Hot dipped?
If the Monitor enclosures is not hot dipped in a zinc wash, this compound forms a galvanised finish on the base metal that stops from rust attacking the steel. Then the steel LCD enclosure is then powder coated, the reason for this process is that if for some reason such as a vandal or hooligan tries to damage the casing and chips the top coat of paint, the base material is still protected by the zinc coating, or else the base material will start to rust and the enclosure in the end will have to be replaced before it should.
So next time you are looking for a steel LCD enclosure, ask them if it is hot dipped and get them to give you addition information, if they have to email you later, they obviously do not know their product and more than likely will not hot dip the enclosure.
Stainless steel LCD enclosure.
Now in some reasons, customers have to have a stainless steel unit, this could be in a food environment or just used to present factory information systems, and the entire production area is washed down at the end of every working day.
Stainless steel substance is available in three forms 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 actually produce them they will know right away.
Nevertheless they are several LCD enclosure suppliers who buy in components from third world suppliers, getting the lowest priced product possible and assemble them, the challenge 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 enclosure was made from, so that you cans ee the original of the metal and safeguard your investment.
