Features

Dual Substrate Options:

PPGI (Pre-Painted Galvanized): Zinc coating for general corrosion resistance, ideal for inland or moderate-humidity environments.

PPGL (Pre-Painted Galvalume): Aluminum-zinc alloy coating for superior coastal/industrial protection, with 30% longer lifespan.

Enhanced Mechanical Properties:

Tensile strength: 270-550 MPa, depending on thickness and substrate.

Wind resistance: Tested to withstand 150 mph (240 km/h) in hurricane-prone regions.

Low Thermal Expansion: The corrugated design accommodates seasonal temperature changes, reducing stress on fasteners and minimizing cracking risks.

Design Flexibility: Over 50 standard colors and custom painting services allow alignment with brand identities or local building codes, including metallic and matte finishes.

Sustainable Choice: 100% recyclable at end-of-life, with low embodied energy compared to ceramic or asphalt roofing materials.

Application

Residential Roofing: Popular for single-family homes, apartments, and cottages, offering a cost-effective, low-maintenance alternative to traditional roofing materials.

Commercial & Institutional Buildings: Used in schools, hospitals, and office parks, where fire resistance (non-combustible steel) and long warranty periods (10-20 years) are critical.

Industrial Facilities: Protects warehouses, factories, and workshops from airborne pollutants and heavy machinery vibrations, with darker colors hiding dirt in polluted areas.

Infrastructure Projects: Suitable for airports, train stations, and stadiums, combining large-span capability with modern aesthetic appeal.

FAQ

Q: Can I walk on these sheets during installation?

A: Yes, but use protective footwear and distribute weight evenly; avoid stepping on the crest of the waves to prevent denting.

Q: What is the difference between PPGI and PPGL in terms of coating?

A: PPGI has a pure zinc base with polymer topcoat, while PPGL uses a galvalume base for enhanced corrosion resistance—choose based on environmental severity.

Q: Do these sheets require an underlayment?

A: An underlayment is recommended for insulation and additional waterproofing, especially in regions with heavy rain or snow.

Q: Can they be used in combination with solar panels?

A: Yes, the corrugated structure provides secure mounting points for solar brackets, with proper flashing to maintain watertightness.
