Frequently Asked Questions
Which finish suits outdoor use?
Powder coating over a conversion coating is the default. For marine exposure, combine it with A360 alloy and a thicker film.
How many hours of salt spray can you achieve?
Up to 500 hours on the right system. Tell us the requirement and we will specify the coating stack to meet it.
Can you match a specific RAL or Pantone colour?
Yes, for powder and liquid paint. Send the reference and we will confirm before production.
Do you finish parts cast elsewhere?
Yes, subject to a sample review to confirm the substrate is suitable.
