Trislot screens are composed of a series of  parallel profiles, that are welded in an automated process perpendicularly on support profiles. All dimensions are variable (slot openings between 0,1 mm and 20 mm are possible) and Trislot offers a wide range of different triangular and support profiles  in several stainless steel alloys.

Our custom-made elements are ideal for use in prestigious building projects to suit the needs of  designers and architects. Trislot grilles are manufactured to the highest standard and are not only aesthetically pleasing but are also robust and durable in the highest demanding locations.

We can offer our technical support from concept to final design.

Pickling is our standard finish to remove all oxidation from the welding process. If required, we can also glass bead blast the screens to get a matt finish or electro polish to get a mirror effect. If a certain colour is required, we can spray paint our screens. (not advisable for pedestrian traffic)


We can supply the grilles with frames and/or fixation points
