Product Description:
PPGI steel coil, a pre-coated galvanized iron product, undergoes a zinc coating process to improve its resistance to corrosion. It is further treated with an epoxy or modified polyester paint coating to ensure better adhesion and durability. Known for its excellent formability and paintability, PPGI steel coil is suitable for a wide range of applications. The coil has an inner diameter of 508/610mm, a zinc coating weight of 30-275g/m2, and a width that varies from 600-1250mm. It comes in a variety of colors, including plus green, beige, final blue, and others. This type of steel coil is particularly well-suited for roofing and walling purposes and finds use in various industries.

Key Features of PPGL Steel Coil
1. Superior Corrosion Resistance
The aluminum-zinc alloy coating provides robust protection against rust, even in coastal or high-humidity environments.
The prepainted layer (PE/SMP/PVDF) adds an extra barrier against UV rays, chemicals, and abrasion.
2. Long-Term Durability
Withstands extreme weather conditions (heat, rain, snow) and maintains structural integrity for over 20-25 years.
UV-resistant coatings prevent fading, ensuring lasting color vibrancy.
3. High Strength & Lightweight
Offers excellent load-bearing capacity (35–50 kg/sqm for 0.5mm panels) while remaining easy to install.
Ideal for large-span roofing and façades without compromising structural safety.
4. Aesthetic Flexibility
Available in multiple colors, textures (matte/gloss), and finishes to match modern architectural designs.
Applications:
Construction:Roof, walls, doors and Windows, rolling doors, steel structure workshop, warehouse, temporary housing, solar panels.
House Appliances:Refrigerator panel, freezer, air conditioning system.
Traffic Facilities:Airport, subway station, traffic signs.
Packing and Shipping:
PPGI Steel Coil are usually packaged and shipped in coil form, tied with steel strips and wrapped with plastic film to protect from moisture. The steel coil can then be loaded onto trucks and vessels for transportation.
FAQ:
Q1:Which is better galvanized or galvalume?
A: As we've mentioned already, Galvalume tends to last almost twice as long as galvanized steel before it shows any signs of wear. This is mainly due to the aluminum that is added to the coating to prevent oxidation.
Q2: Can I get some samples?
A: Can provide small samples for free. Customized sample takes 5-7 days.
Q3: How about the delivery time?
A: Small trial order takes 5-7 days. Container order need 15-20 days.
Q4: What is the difference between PPGI and GI sheet?
A: GI is preferred in situations that require high resistance to corrosion and harsh environmental conditions, PPGI is used in situations where aesthetics matter or where a specific color or texture is required. Overall, both GI and PPGI are reliable and versatile materials that can be used in a variety of applications.
