The completely concealed hinge system


"Making something invisible is also design!" There is a certain appeal in designing items in such a way that their actual value is initially in the background, thereby giving space to other elements. Flush mounting is a stylistic principle that exudes minimalism and involves precise technology and perfection.


In this way, the completely concealed hinge system TECTUS enables unrebated doors to be completely flush and therefore integrated into rooms designed with straight lines. When closed the door will remain visible, with an invisible hinge system. TECTUS carries load capacities up to 300 kg, enables an opening angle of 180 degrees and can be used on timber, steel and aluminium frames. Three-dimensional adjustment and maintenance-free slide bearing technology are used for high-quality interior doors and functional heavy-duty doors.

Innovation born out of tradition

The wide range of surfaces enables a variety of applications – they can be harmoniously tailored to an architectural concept and fittings and can completely blend into the background when the respective door is closed.


Since 2002, TECTUS has been an integral part of the SIMONSWERK product range and thanks to its ongoing development, it is now more innovative and efficient than ever. From simple interior doors to large, heavy-duty doors – the hinge system TECTUS is the ideal solution for any requirement.

"Black" Finish sets new accents in door design


Black is the trend colour for 2018 in interior design. From black kitchen fronts, household and electrical appliances to completely black furniture and living rooms: the black colour sets new accents in the living area and visually refines aesthetics to the essentials.

When combined and co-ordinated with other trend materials such as concrete, light oak or steel in rust-optic it gives areas  a cool and minimalist touch.


SIMONSWERK also focuses on a reduced, straight forward look to meet the demand for dark finishes.
