12 Gauge Galvanized Corrugated Steel Roofing Sheet Color Coated

Brand ZCXH
Product origin Shandong,China
Delivery time 10-20 days
Supply capacity 1000 tons/ month

Our Galvanized Color Coated Corrugated Steel Roofing Sheets combine durability and aesthetics. The galvanized base with a zinc coating resists rust and corrosion, while the color layer adds UV protection and vibrant, fade-resistant hues. The corrugated profile boosts strength, handling wind, rain, and snow. Lightweight yet sturdy, they’re easy to install, cutting labor costs. Ideal for roofs in residential, industrial, or agricultural settings—offering long life, low maintenance, and a polished look. A perfect blend of functionality and visual appeal.

Production Process

Galvanized Corrugated Steel Roofing Sheet Color Coated

Product Description

Superior Structural Strength
With a thickness corresponding to 12 gauge (approximately 2.73mm), the sheet offers excellent load-bearing capacity and impact resistance. It can withstand moderate snow loads, strong winds, and minor external impacts without easy deformation, ensuring long-term structural stability for roofing systems.
Enhanced Corrosion Resistance from Galvanization
The base steel is hot-dip galvanized (coated with a layer of zinc). Zinc acts as a sacrificial anode, effectively isolating the steel substrate from moisture, oxygen, and corrosive substances (such as rainwater, humidity, or industrial fumes). This significantly prevents rusting and extends the sheet’s service life, especially in outdoor or moderately corrosive environments.

Corrugated Steel Roof Sheet

Vibrant & Durable Color Coating
The surface is covered with a high-quality color coating (typically polyester, PVDF, or PE coatings). This coating not only provides a wide range of color options (to match architectural aesthetics) but also boasts excellent weather resistance—resisting fading, chalking, and peeling even after long-term exposure to sunlight, UV rays, and extreme temperatures (high heat or cold).
Corrugated Design Advantages
The corrugated profile enhances two key performance aspects:

Increased Rigidity: The wave-like structure improves the sheet’s bending resistance, reducing the need for excessive supporting frames and lowering installation costs.
Efficient Water Drainage: The sloped corrugations facilitate quick runoff of rainwater and melted snow, preventing water accumulation on the roof (which could lead to leaks or structural damage).

Lightweight & Easy Installation
Compared to traditional roofing materials (e.g., concrete tiles, clay tiles), 12 gauge galvanized color-coated steel sheets are much lighter. This reduces the overall load on the building’s roof structure and simplifies transportation, handling, and on-site installation—saving time and labor costs.
