Casting producers and purchasers of castings can specify and assess surface quality, surface texture more accurately with definitive tactile comparators developed by us.

Potential specification disputes between suppliers and users can be avoided via this common and recognisable reference point. Scrata Surface Comparators provide a practical and functional alternative to photographic representation of casting surfaces in standards such as MSS SP-55-2001.

Thousands of comparators are in use internationally on a daily basis. The durable comparator plates are  replicas of relevant characteristics of a component surface finish and can be used to ensure compliance between casting manufacturers and specifiers.
