With a rich history rooted in functional design, d line has consistently delivered high-quality products that cater to the needs of architects and designers. Beginning in the 1960s, d line's journey started when Knud Holscher, a Danish designer, recognized the demand for a coordinated line of stainless steel architectural products. This led to the creation of the first d line products in 1971, including two lever handles - the Ø14mm U and L.

These handles stood out with their distinctive shape, maintaining the radius of their cross sections through sharply bent sections. Since then, d line has expanded its product range and collaborated with renowned designers to bring innovative solutions to the market. Their extensive collections, such as Knud Holscher, Eisenware, Arne Jacobsen, Qtoo, and Tom Dixon, offer a wide variety of door and window hardware, bathroom accessories, taps and showers, sanitary panels, barrier-free solutions, and access control systems.

Architects and designers choose d line products for their exceptional craftsmanship, functionality, and enduring design. With d line, you can expect unparalleled quality and enduring beauty for your architectural projects
