Corten steel profiles combine strength, durability and aesthetics. Valued in architecture and design, corten stands out for its typical oxidized finish: besides giving a warm, natural look, it protects the metal from corrosion without any painting.
Sika produces open and tubular corten profiles by cold roll forming, starting from coil strip and shaping the section to the customer’s drawing. They suit both outdoor and indoor use, with a long service life and a strong visual impact.
Corten steel profiles are produced from coil strip, slit to the width required for the section. The strip is then roll formed, punched or bent according to the project. The profile keeps its high structural strength and, once exposed to the air, naturally develops the surface patina that protects it from weathering.
Cold roll forming involves passing steel strips through progressive rollers that gradually shape the section until the desired form is achieved. This method ensures excellent dimensional tolerances and allows the production of open or closed profiles with even complex geometries, while maintaining the high strength typical of corten steel.
Cold stamping uses presses equipped with dies to give the sheets three-dimensional shapes and sharp bends. With this technique, it is possible to obtain structural elements, decorative components, or specific parts for sectors such as metal carpentry and urban furnishing, making the most of corten’s distinctive surface patina.
Punching is often integrated into the previous processes, allowing holes, slots, or various openings to be created with a high level of precision. These operations facilitate subsequent assembly, reducing production times and offering better adaptability of the parts in industrial or architectural contexts.
Bending allows for the creation of arches, curves, or shaped sections using rollers or specialized bending machines. This process is especially appreciated when aiming to create aesthetically unique structures such as railings, roofing, or furniture elements without compromising the typical strength of corten steel.
Corten steel forms a stable and adherent layer of rust that halts the progression of oxidation and significantly reduces the need for maintenance. This protective phenomenon is accompanied by excellent mechanical resistance and the absence of aggressive chemical treatments, making it suitable for use in environments heavily exposed to rain, sunlight, and thermal fluctuations. Thanks to these features, corten steel profiles integrate easily into contemporary architectural projects, urban infrastructure, and outdoor furnishings, providing a distinctive aesthetic that evolves over time.
The surface patina drastically slows down the oxidation process.
The warm, natural color blends seamlessly with architectural design contexts.
Corten steel maintains excellent mechanical properties, ideal for outdoor use.
The self-protective finish requires minimal intervention, reducing time and costs in the long term.
In corten steel we produce open U, C and omega sections, closed square, rectangular and round tubes, and special sections made to drawing. Cold roll forming lets us tailor thickness, width, height and geometry to the project, with the same strength and durability in every section.
Corten steel tubes are made by roll forming the strip until the section closes, then welding it continuously with HF welding. The result is a square, rectangular or round tube with all the properties of corten: protective patina, weather resistance and no painting.
Railings, fences, pergolas, facade frames, urban furniture and garden structures: outdoor applications that need a rigid closed section and a look that improves over time.
Tubes can be punched, slotted, bent and cut to length, so they arrive ready for assembly.
One of the most appreciated applications involves corten steel vineyard posts, which ensure strength and longevity even in variable weather conditions. The naturally forming surface patina protects the post from corrosion and reduces the need for maintenance over time. Moreover, its warm, natural color blends perfectly with the rural landscape.
Corten steel profiles are used in construction, architecture and urban furniture for facades, railings, exterior cladding, pergolas and fences. Weather resistance and structural strength make them ideal outdoors, and the absence of paint keeps maintenance costs low over time.
No. Exposed to the air, corten forms a stable, adherent oxide patina on its own, which slows down corrosion. No painting or anti-corrosion treatment is needed, and maintenance stays minimal.
Yes. We produce square, rectangular and round corten tubes, cold roll formed and HF welded, which can also be punched, bent and cut to length.
