All lines are made out of first-rate materials and undergo stringent quality controls (MEDAL is ISO 9001 certified).

MEDAL cremone bolts come in the following materials:
  • die-cast aluminium
    • internal mechanisms (12-15 ISO EN 1774 Standard Zn+Al+Mg alloy)
    • enclosure and handle (EN 1774 Standard die-cast aluminium alloy)
     
PVD coating

PVD coating is a recently applied technique that enhances material surface resistance and is hence an especially suitable treatment for heavy-duty items.

What's more, the treatment confers an appealing colour. That's why MEDAL has also adopted the technique for its cremone bolt lines, thus combining good looks with maximum surface resistance over time.

The treatment is wholly environmentfriendly and consists in applying a zirconium nitride layer under controlled atmosphere conditions, an undisputed improvement over the traditional and highly polluting chromium plating technique...

Other advantages of PVD coating include:
  • high abrasion resistance;
  • high corrosion resistance;
  • long-lasting and persistent colours capable of safely with standing high temperatures;
  • enhanced appearance;
  • no processing-derived pollution.
