Panting But on a Much Larger Scale

Have you driven over a huge bridge and wondered what it might have taken to cover the whole thing in paint? A child that’s seen their home’s walls being painted might imagine that the bridge might have been painted by a thousand workers by hand but you’d know that it would’ve cost millions of dollars to pay that many painters working at such a height and taken years to complete.

So, the question remains, how do huge metal bridges get painted, after all? You can get the full article here. The answer to that is rather clever; have you ever heard of gold plating? We’re asking you this because gold plating includes an electrical charge being run through a solution containing the gold, which then starts to form a coating on the targeted piece of metal. Metal bridges are painted with half the same concept; the metal part is charged with electricity and then a powdered coat can be applied to it.

This method of industrial painting was originally intended for metal surfaces only but thanks to how far technology has come, we can how charge wooden and plastic surfaces as well and finely coat them with payers of powered paint for a perfect finish. In the case of metal bridges that need to be coated quickly so that they can be used by the public soon, coil coating might be an even better method.

Coil coating involves rapid application of paint using a roller, which makes it great for covering large metallic surfaces like bridges and industrial containers. The powder coating method can be impractical for extremely large surfaces because of how there would be a need for way too much electricity to charge the entire bridge.
