What is blue corrugated roof sheet?

Blue corrugated roof sheet is a building roof sheet with a blue appearance and wavy texture. It can be a blue PPGI sheet, a blue PPGL sheet, a blue color-coated steel sheet, or a blue color-coated aluminum sheet. It is formed by coating one or more layers of organic coating on its surface after surface pretreatment, and then baking and curing. The roof sheet is light in weight, high in strength, good in corrosion resistance, and easy to install. The blue color can meet the needs of different architectural styles.

Blue Corrugated Roofing Sheets Key Features

• Quick installation: can be directly fixed on the steel structure with self-tapping screws. Save a lot of manpower.
• Low cost: more economical than glazed tiles and aluminum-magnesium-manganese plates, but with excellent performance. Suitable for bulk purchase or home use.
• Lightweight: Corrugated sheet roofs are usually made of lightweight materials, such as galvanized steel sheets, aluminum sheets, etc., so they are light in weight and easy to transport.
• High strength: The corrugated design gives this material high strength and rigidity, and can withstand greater wind and snow pressure.
• Waterproof and anti-corrosion: Corrugated sheet roofs are usually surface-treated with high-quality coatings, which have excellent waterproof and anti-corrosion properties and can extend their service life.

Production process

• Substrate selection: Use galvanized steel sheet (GI) or aluminum zinc steel sheet (GL) as the substrate.
• Surface pretreatment: Remove oil stains on the steel sheet surface by alkaline solution, and form an anti-corrosion layer by phosphating.
• Coating process: Roller-coat anti-corrosion primer, apply blue topcoat, and bake at 200℃ to solidify the coating.
• Cold pressing: Use multiple groups of rollers to gradually press out a wavy profile. Common wave types are trapezoidal waves and sine waves. The wave height range is 15-50mm.
• Quality inspection: Check the length, wave height, wave distance, etc., check the coating thickness with a thickness gauge, and conduct mechanical performance tests such as bending and impact.
• Packaging: Use PE film to wrap to prevent scratches, and each 10-20 pieces are a bundle, indicating the specifications, quantity, and production date.

Uses of  Blue Corrugated Roofing Sheet

1. Factory buildings: roofs and walls of light steel structure factories. Large-span roofs, rainproof and rustproof. Temporary or permanent building covers.
2. Agriculture and breeding: Greenhouses replace plastic films and are more durable. Pig houses, chicken houses, cattle sheds, etc., easy to clean and corrosion-resistant. Grain storage: moisture-proof and rat-proof.
3. Commercial and public facilities: roofs of farmers’ market stalls. Parking lots/carports. Stadium stands or enclosures.
4. Residential and temporary buildings: sloping roofs or canopies, temporary housing on construction sites, disaster relief houses. Garages/storage rooms, low-cost and quick to build.
5. Others: solar panel brackets for photovoltaic projects, shielding barriers for highways or construction sites

Recommended applications for different thicknesses

1) 0.3mm (30 gauge) – Lightweight, suitable for temporary structures.
2) 0.4mm(28 gauge) – Standard for residential & commercial roofs.
3) 0.5mm(26 gauge) – Heavy-duty, used in industrial buildings.
4) 0.6mm+(24 gauge & below) – Extra strength for high-wind areas.

Key Considerations When Choosing Size

• Roof Pitch : Steeper roofs may need narrower sheets for better runoff.
• Wind & Snow Load: Thicker gauges (0.5mm+) for high-wind/snow regions.
• Overlap Requirement: Typically 100-150mm side overlapand 200-300mm end overlap.
• Local Building Codes: Some regions mandate minimum thickness for durability.
