Galvanized 201 corrugated stainless steel sheet is cold‑rolled and specially treated with zero‑spangle galvanizing process. It combines the advantages of 201 stainless steel and galvanized layer, featuring strong rust resistance, lightweight, high strength and good waterproof performance. With professional corrugated forming, it is perfectly designed for roof covering projects, providing stable drainage and long‑term weather resistance.

Custom sizes, thicknesses and corrugation patterns are available upon request.

Zero‑spangle means the galvanized surface presents uniform matte finish without visible zinc grains. It looks neater, more delicate, and has better corrosion resistance than regular spangle surface, ideal for outdoor roof use.

• Trapezoidal corrugation: stable structure, good load‑bearing, widely used for industrial factory roofs
• Wave‑type corrugation: excellent drainage performance, suitable for large‑area roofing projects
• Custom corrugation shapes available

• Industrial factory roofs
• Warehouse and workshop roofing
• Farm barns, livestock sheds
• Temporary buildings and prefabricated houses

• Carport roofs, sunshade canopies
• Wall cladding for simple buildings
• Rainproof roofing for public facilities

• Greenhouse roofing
• Small‑house roof renovation
• Waterproof and windproof covering projects

• Cleaning: Use neutral water or mild detergent to wash dust and dirt regularly; avoid strong acid‑alkali cleaners.
• Anti‑rust: Zero‑spangle galvanized layer greatly improves rust resistance; keep roof drainage unobstructed to prevent long‑term water accumulation.
• Durability: Cold‑rolled high‑strength base material resists wind, rain and sunlight aging, with long service life.
