#1 – DOES THE BACK SIDE NEED TO BE PAINTED/SEALED?
No. Since weathered steel is an alloy made of non-corrosive metals, the properties run through the whole product. Therefore, the backside of the panel will form the same protective layer as the face.
#2 – DOES WEATHERED STEEL CORRODE INDEFINITELY?
No. The naturally occurring outer layer prevents any further exposure to the climate, and effectively “seals” the panel.
#3 – I’VE HEARD WEATHERED STEEL CAN STAIN ADJACENT AREAS OF THE BUILDING. IS THAT TRUE?
It depends. When panels are first installed they have the highest likelihood to bleed and stain adjacent areas of the building. Based on our experience with past projects, Kovach has developed ways to reduce the impact of staining. For example, allowing panels to patina naturally prior to installation can significantly reduce run-off. If you are concerned about staining, please give us a call and we can talk through ways to manage this on your project.
#4 – WHAT APPLICATIONS ARE NOT RECOMMENDED FOR WEATHERED STEEL CLADDING?
Environments that are heavy with salt, fog, and generally wet climates. Weathered steel must have periods where it can dry out, otherwise the corrosive protective layer will never fully form. Also, any applications where water is continually running, such as gutters, leaders, water features, etc. are not recommended.
#5 – ARE THERE PAINTED OPTIONS THAT LOOK LIKE WEATHERED STEEL?
Yes. If you desire the look of weathered steel but project constraints eliminate it as a viable option (such as climate), you can opt for painted products. Kovach has a great network of vendors that can supply painted products that are practically indistinguishable from naturally occurring weathered steel.
