Here at Midland trailers, we get asked how our sandblasting process work, do we do it on-site? Or do we just etch prime and powder coat?
The short answer is NO we don’t etch prime and powder coat like some of the other trailers in the market, who use a wet spray finish. We complete our trailers in our facility here in Parkes they are then transported to our Powder coaters in Cowra.
The sandblasting process is undertaken in a dedicated sandblasting room just before the zinc undercoat is applied, this is to ensure the surface does not being to rust.
There are many different grades or classes of sandblasting we sandblast every trailer to class 2 1/2 or near white finish to ensure all the millscale and rust is removed and we have a perfect surface to seal with our undercoat.
