Corten steel roof extractor Corrosion Resistance: It protects itself by forming a stable patina that prevents further oxidation. Reduction of electrochemical corrosion thanks to the porous external layer and the waterproof internal layer rich in copper, chromium and phosphorus. Tensile Strength: High mechanical resistance, higher than that of traditional steel. Durability: Longevity and less need for maintenance. Resists up to 700° C - Even in the event of a fire in the chimney 8 year warranty Up to 3800 M³/h (equipped with 6-speed regulator) Product certified in accordance with CE law Universal (for any type of flue, even irregularly shaped ones) CHIMNEY EXHAUST FAN GEMI ELECTRONICS Professional Model Corten Steel Corten Steel Characteristics The term "Corten" comes from the combination of "CORrosion resistance" and "TENsile strength", indicating its two main properties. Corrosion Resistance: Self-protects by forming a stable patina that prevents further oxidation. Reduction of electrochemical corrosion thanks to the porous outer layer and the impermeable inner layer rich in copper, chromium, and phosphorus. Tensile Strength: High mechanical strength, superior to traditional steel. Durability: Longevity and less maintenance required. Protective coating that evolves in about 18-36 months, giving the material a rust color that varies from initial orange to reddish-brown. Aesthetics: Distinctive and variable appearance, with a matte and uniform surface. Used in modern architectural designs for its aesthetic and protective effect, but even more so in rural settings, as this type of material perfectly harmonizes with greenery and nature. Versatility: Suitable for both indoor and outdoor use, applicable in various settings. Paint or wax treatments to prevent flaking to the touch. Sustainability: Reduction in the use of paints and chemical coatings, minimizing environmental impact. Strengths compared to iron Compared to Iron: Does not require constant protective treatments. Not subject to flaking and peeling like oxidized iron. Combines aesthetics and functionality, offering unique designs. Greater resistance to atmospheric agents compared to painted materials. Why Choose It: Longevity: Long-term investment due to its durability. Low Maintenance: Minimal maintenance requirements compared to other materials. Aesthetic Impact: Perfect for those seeking a distinctive and modern design. Versatility: Suitable for multiple applications, both indoors and outdoors. Unique. 20 reasons to choose it.
