Roofing Sheet is a plain carbon steel sheet coated in a galvanizing process that applies a barrier of zinc to insulate it from the elements. Most corrugated roofing and siding products today are manufactured with a galvanized finish, recognized for commercial, agricultural, industrial, and residential applications.
Key Advantages: Galvanizing protects the steel from immediate rust. This electro-coated, hot-dipped process creates a silvery, spangled finish that enhances durability compared to normal steel sheets.

A: Depending on the zinc coating thickness and environmental conditions, galvanized sheets can last between 20 to 50 years. Higher zinc coating (up to 275g/m²) offers better corrosion resistance in harsh environments.
A: Yes, corrugated galvanized sheets are extremely versatile and are commonly used for commercial, agricultural, industrial siding, and residential roofing.
A: Spangle refers to the visible metallic grains on the surface. Regular spangle has the traditional "flower" pattern, while zero spangle has a smooth, uniform finish, often preferred if the sheet is to be painted.
A: We use a 3-layer professional packing system including kraft paper, waterproof plastic film, and an outer GI steel sheet cover secured with steel strips to prevent moisture and physical damage.
A: Absolutely. We accept and encourage inspections from independent parties like SGS, BV, and AI to ensure the highest quality standards are met before shipping.
A: A standard order is typically 25 tons (one container), but we can accommodate smaller quantities. Please contact us to discuss specific requirements.
