Lock Lock anti-pitting test exceeds 3,000 hours – 2,760 over standard


Lock Lock, the new high security handle from Brisant Secure, has spent over 3,000 hours or four MONTHS – in independent corrosion testing, with no sign of pitting or blistering. Just 240 hours, or 10 days, of salt spray testing is required to achieve the EN 1906:2012. The highest corrosion grade measured is 480 hours.

“Pitting on door furniture is one of the industry’s dirtiest secrets,” says Nick Dutton, CEO of Brisant Secure. “In fact, Lock Lock has spent longer in the salt spray chamber than some handles I used to buy lasted on the door. Many manufacturers only offer a guarantee on performance, or a token one on the finish. Some recommend stainless steel for coastal areas but 63% of the UK population live less than 9.3 miles from the sea. And 36% live within just 3 miles! In fact, most of us are near the coast, and the issues we have in the UK with corrosion on door handles reflects that. What might be fine for inland Europe, America or Australia, just isn’t suitable for an island like ours.”

Nick adds: “As manufacturers we can and should do better. Lock Lock took 24 months to develop. Each handle is coated twice with copper and then twice with nickel, and its designed with a seamless curve so there are no edges or corners, traditional weak spots for corrosion. The industry needs to ask itself why it’s finish guarantees aren’t anywhere near those for performance or security. Homeowners expect their handles to look good for years, not months. But all too often the reality is sadly different.”
