For durability, corrosion resistance, tensile and shear strength, stainless steel louvers are a great choice. Stainless steel louvers are chosen often for their long lasting attractive appearance, perfect for building facades where louvers will be highly visible. Stainless steel also retains its strength at high temperatures, which can be a factor in extreme environments. Stainless steel has hygienic advantages, making it the right choice for louvers that might be used in clean room environments, in laboratories, and in pharmaceutical or food processing situations. Stainless steel louvers do not require painting, anodizing or other surface treatments. Stainless steel louvers are a great choice for harsh and corrosive environments. And while stainless steel is initially more costly than other materials, its low maintenance needs and long life expectancy can make it the most cost-effective over the long run.
