One year and counting

In 2018, Brisant-Secure announced that one of their Sweet door handles had managed survive in a salt spray chamber for 8,056 hours, when the standard is only 240 hours.

Twelve months on, and Brisant put a Sweet letterplate into the same accredited test chamber and waited. Even though the letterbox had not failed, it was taken out of the chamber after one year and 28 days. A standard requirement is for only 10 days, and enhanced is 20.

Nick Dutton, CEO of Brisant-Secure, said: “We kept the test quiet because there wasn’t anything to really talk about until we passed the previous benchmark. When we passed our previous of 8,000 hours, we felt we may as well see if it manages a whole year before announcing it. Even though it was still going strong at this point, we thought it timely to bring something out of isolation. Underneath the salt it still looks amazing.”

Sweet is rounded, and so water runs off it quickly, and it has the same six-coat plating process that is used on bathroom products. These are designed from the outset to be submerged in water yet never pit or corrode.

Therefore, Brisant felt confident to double the direct-to-homeowner corrosion guarantee to 20 years on all of the colours.
