Why should metal be powder coated rather than painted?
When you enquire about certain products that we offer here at K&S Metals (http://www.ksmetals.net), such as our safety barriers, you may be given the option to have them powder coated. Certainly, this is not the only finishing option that you can specify for your metal components, with zinc plating being another speciality of ours, but perhaps the most obvious alternative to powder coating is simply having the metal painted. What makes powder coating the better option for your next order with us?
Painting metal was, after all, the norm prior to the development of powder coating as a direct alternative in the 1940s and 1950s. One of the problems with paint is that it bonds poorly with items created via metal fabrication, with only a certain amount of paint also able to be applied before the maximum thickness is reached. Powder coating, in contrast, ensures a rather more uniform coating on metal. The coat can be thicker, in addition to offering greater durability and resistance against scratching, peeling, rusting and cracking.
Another major attraction for those who turn to us for metal components is our extremely competitive pricing, and sure enough, powder coating is highly cost-effective, on account of the recyclability of the overspray. This cuts down on wasted paint, not to mention hazardous waste. The powder coating process itself is easy to understand for those purchasing the likes of fall prevention products from us. First, the coat of powder material is applied to an item. Secondly, the powder needs to be cured.
The application of the powder can be done with an electrostatic gun, from which the powder is sprayed. Alternatively - and this happens less often - the item can be dipped into a fluidised bed. To cure the powder, the item needs to be heated up in a gas-fired convection bake oven. This results in the powder melting and forming a smooth film. Although it has long been customary for the powder to require curing for 10 to 15 minutes at 400 degrees F (204 degrees C), subsequent technological developments
have brought further energy savings that can be passed onto the customer, with powders now able to be cured at lower temperatures of 300 to 325 degrees F (149 to 163 degrees C).
Once the curing process concludes, the products are left to cool off, leaving a very rugged and absolutely flawless finish - as is necessary given the required applications of such products in industries including construction. The inexpensiveness, environmental friendliness and long-lasting durability of powder finishes has made them widespread in metal fabrication. But whatever components you request from K&S Metals (http://www.ksmetals.net), from hand tools to tube spanners, we can ensure that the item meets your exact specification and sports the most appropriate finish for the task in hand.
