When it comes to withstanding harsh weather conditions, roofing and cladding materials need to provide exceptional durability and resilience. In recent years, PPGL steel coils have become a preferred choice for such applications. Known for their weather-resistant properties, these coils offer superior protection against intense heat, heavy rainfall, and even extreme cold.
Their durability, combined with cost-effectiveness, makes them ideal for use in both residential and industrial projects. In this guide, we will explore how PPGL steel coils perform under extreme weather conditions, their benefits, and why they are the best steel for extreme weather.
What Are PPGL Steel Coils?
PPGL (Pre-Painted Galvalume) steel coils are made from galvalume-coated steel with a layer of paint applied to enhance protection and aesthetic appeal. The galvalume coating consists of 55% aluminum, 43.5% zinc, and 1.5% silicon, which offers exceptional corrosion resistance. The additional paint layer boosts the coil’s ability to withstand harsh weather conditions, making it suitable for roofing, cladding, and structural applications.
Key Features of PPGL Steel Coils
- Corrosion Resistance: The galvalume coating protects against rust and oxidation.
- Thermal Reflectivity: Reduces heat absorption, making them perfect for hot climates.
- Weather Resistance: Withstands heavy rain, humidity, and temperature fluctuations.
- Aesthetic Appeal: Available in various colours and finishes, adding visual value to structures.
Why Choose PPGL Steel Coils for Extreme Weather?
Using PPGL roofing for high temperatures or heavy rainfall offers several advantages, making it the best steel for extreme weather. Here’s why they are the go-to choice:
1. High-Temperature Resistance
In regions with scorching temperatures, roofing materials must withstand prolonged exposure to UV rays without deteriorating. PPGL steel coils feature a reflective surface that minimises heat absorption, keeping the internal environment cooler. This makes them ideal for industrial warehouses, commercial buildings, and residential properties in hot climates.
2. Corrosion and Moisture Resistance
Heavy rainfall and humidity can quickly deteriorate standard steel. However, weather-resistant PPGL steel has a protective coating that prevents rust and corrosion. This makes it perfect for coastal areas and regions with frequent rainstorms.
3. Cold Weather Endurance
In freezing temperatures, some roofing materials can become brittle or crack. However, PPGL steel coils maintain their flexibility and strength, making them ideal for regions with extreme winters. Their anti-corrosive properties protect against damage from snow and ice buildup.
4. Wind and Storm Durability
PPGL steel roofing and cladding offer superior tensile strength, making them resistant to high winds and storms. Their robust design ensures they remain intact, reducing the risk of damage during extreme weather events.
Applications of PPGL Steel Coils in Extreme Weather Conditions
Here’s how PPGL steel coils are effectively used in various applications to combat extreme weather:
1. Residential Roofing
- Withstands heat and rain effectively.
- Ensures long-term protection against UV rays and moisture damage.
- Reduces cooling costs due to reflective properties.
2. Commercial Buildings
- Ideal for industrial warehouses and factories.
- Resistant to temperature fluctuations and corrosion.
- Provides structural stability during storms.
3. Infrastructure Projects
- Used for bridges, tunnels, and transportation shelters.
- Withstands weather-related stress, including heat, rain, and snow.
- Enhances longevity with minimal maintenance.
Comparison of PPGL Steel Coils with Other Roofing Materials
Here’s a comparison table highlighting why PPGL steel coils are a superior choice for extreme weather conditions:
| Feature | PPGL Steel Coils | Galvanised Steel | Aluminium Roofing |
| Weather Resistance | Excellent (Resists heat, rain, and cold) | Good (Prone to rust over time) | Moderate (Prone to denting) |
| Corrosion Resistance | High (Galvalume + paint layer) | Moderate (Zinc coating only) | Low (Prone to salt damage) |
| Thermal Reflectivity | High (Reduces heat absorption) | Low | High |
| Lifespan | 40+ years | 20-30 years | 25-30 years |
| Maintenance | Low | Medium | High (Frequent cleaning) |
| Cost-effectiveness | High (Durable, low maintenance) | Medium (Frequent repairs) | High (Higher material costs) |
Tips for Using PPGL Steel Coils in Extreme Weather
To ensure optimal performance in harsh climates, here are some tips for using PPGL steel coils effectively:
1. Choose the Right Thickness
- For regions with heavy snowfall or storms, opt for thicker coils (0.50 mm or above) to withstand impact and pressure.
- Thinner coils (0.35 mm – 0.45 mm) are suitable for moderate weather conditions.
2. Ensure Proper Installation
- Use weatherproof fasteners and sealants to prevent leaks.
- Ensure proper overlap and alignment to avoid gaps that can let in moisture or wind.
3. Regular Maintenance
- Clean the roofing annually to prevent dirt buildup and maintain reflectivity.
- Inspect for scratches or paint wear and touch up with compatible coatings to prevent rusting.
Why Choose PPGL Steel Coils from a Trusted Manufacturer?
To guarantee the best performance, source your coils from a reputable PPGL steel coils manufacturer in India. Reliable manufacturers offer:
- High-grade steel with consistent coating quality.
- Customisable options in thickness, width, and colour.
