Steel EMI Shielding –

In the midst of all of this electronic activity are random electrical signals that pass through the air and can cause serious damage to our devices. To protect equipment, it is important to have some form of blockage that can prevent the random signals from damaging or destroying vital equipment. The best form of protection is EMI steel shielding.

The random electrical pulses that float through the air are called electromagnetic interference (EMI). Steel shielding is designed to either absorb or resist EMI’s and is best form of shielding since it can deflect or absorb stray electrons. Steel is a very durable metal that has many features, which makes it a perfect solution for protecting technical equipment.

A critical factor in the battle against EMI’s is corrosion, which can interrupt electrical signals and permanently damage equipment. Of the many forms of shields on the market, steel shielding, with an added alloy such as zinc, tin or aluminum, is exceptional in avoiding and preventing corrosion. The dangers associated with corrosion are not normally seen until it has already destroyed equipment.

An additional factor that makes steel shielding attractive is its ability to be soldered. The various forms of shields include cabinets and cases that can hold racks. Steel shielding can be seamlessly soldered and formed to any size for these types of enclosures. The tight seal between connections does not interrupt the protective quality of the steel shielding.

For the best protection, shields need to be assembled in layers since single layered shields do not have sufficient protective capabilities. Steel shielding is produced in multiple thicknesses that makes it capable of being formed into layers in the production process.

The most impressive aspect of steel shielding is its low conductivity making it a perfect choice for a shield designed to prevent the passage of electrons. Its density absorbs electromagnetic interference and sends it to a ground material. The process is completed efficiently without the need for any concern on the part of the user.

There are many forms of shields on the market that may have attractive selling points. For the most economical and cost-efficient choice, steel shielding is far superior to any of the other materials available.
