These black door handles from the 'STERK' brand, finished with a matte black coating, stand out due to their high manufacturing standards, excellent material quality, and all at a very attractive price.
The black project door handles, made of stainless steel, have passed multiple tests, including the PN-EN 1906:2012 fire-resistance test, the level 7 durability test (which requires no fewer than 200,000 test cycles), and a 96-hour salt spray test that resulted in a level 3 corrosion rating. They also passed the fire-resistance test, meaning they can be used on doors with an EI30 fire resistance rating.
In short, high-quality door handles on sprung metal rosettes with cams, perfect for frequent use in residential, office, or public spaces at a competitive price.
