Even high-grade stainless steel coils can degrade without proper care. Regular cleaning with pH-neutral solutions removes contaminants like chlorides or acids that cause pitting corrosion. For coils exposed to saltwater or chemicals, duplex grades provide added protection. Inspect for scratches or dents, which can trap moisture and accelerate rusting. Storage matters too—keep coils dry and elevated to avoid ground moisture. For architectural projects, opt for brushed or polished finishes to simplify upkeep. Partner with suppliers offering post-purchase support, including maintenance guidelines tailored to your coil type.
