Steel, stainless steel, and Corten provide versatile design options while ensuring high stability and efficient fabrication. Each material has distinct properties that influence performance and aesthetics. Steel requires corrosion protection through galvanization, powder coating, or wet lacquering, whereas stainless steel naturally resists corrosion due to its high-quality alloy, maintaining its durability without additional treatment. Its unique color and surface structure enhance its refined appearance. Corten steel, known for its pre-rusted finish, is ideal for achieving an industrial aesthetic while preserving the strength and structural integrity of standard steel.

Jansen applies specialized treatments to materials, ensuring both functional durability and aesthetic versatility. From raw steel to chemically or mechanically refined surfaces, each process enhances the visual and structural properties of profiles and fittings. Surface treatments, including powder coating and mechanical finishing, define color, gloss levels, and metallic effects while meeting specific material requirements. Techniques such as grinding, brushing, and polishing further refine the appearance, offering a range of design possibilities. Beyond aesthetics, Jansen’s approach to surface treatment enhances material protection and can optimize thermal performance by managing heat absorption and solar reflection.
