At Majestic Aluminium Finishing Ltd, we offer a wide range testing services in house and by one of our approved testing suppliers that is a UKAS accredited metallurgical test laboratory to ISO 17025, fully equipped to meet most metallurgical testing needs.

Our primary testing departments are analytical and corrosion science including chemical analysis, painted/plated finish salt spray and humidity testing, mechanical testing and metallography including failure investigations.

We also offer PCN certified Non Destructive Testing including ultrasonic, magnetic particle and dye penetrant inspection on customer site locations. We can also provide radiographic interpretation and arrange for radiography to be carried out at a fixed location.

Our list of services include:

Analytical and Corrosion Science
