In the fields of architecture, manufacturing and infrastructure, demand for durable and cost-effective building materials is on the rise. Coated steel products are preferred, with 60 g color coated coil standing out. What is this? What is the difference between PPGI and PPGL? How do I choose? This guide provides authoritative, data-backed answers to help you leverage its value.

1. What Is 60 G color coated coil? Definitions and core concept
In order to understand 60g color coated steel plate, please clarify the definition of key coated steel plate (including PPGI and PPGL), because they are often confused, but they are different.
1.1 An important Definitions
- Coated Steel: steel plate/coil with protective layers (paint, zinc, aluminum-zinc alloy) to improve corrosion resistance, durability and aesthetics, prevent rust and extending service life (Source: World Steel Association, https://www.worldsteel.org/).
- PPGI (Pre-Painted Galvanized Iron): Coated steel with zinc coating first, then 1-2 organic paint layers. Zinc provides the main protection against corrosion; Paint enhances beauty and protection.
- PPGL (Galvalume Iron Precoated): Similar to PPGI, but with an aluminum-zinc alloy coating (not pure zinc), it has better corrosion resistance in harsh environment.
- 60 g color coated coil: Coated steel plate, with total coating weight of 60 g/me (metal+paint). Produced by Runfei (Tianjin, China), it conforms to AISI/ASTM/BS/DIN/GB/JIS standards, and the quality is stable.
1.2 Data Insight: The Market demand of coated steel
Due to urbanization and the development of infrastructure, the global coated steel market has grown steadily. Grand View Research projects the pre-painted steel market (including PPGI and PPGL) to reach USD 58.7B by 2030 (CAGR 5.2%), driven by construction, automotive and industrial use (Source: Grand View Research, https://www.grandviewresearch.com/).

4. Factors influencing the price of 60 G color coated coil
The price of 60 color-coated coil is influenced by raw materials, coating specifications and packaging. Knowing these will help to optimize procurement and improve cost-effectiveness.
4.1 Zinc or Aluminum-Zinc Coating Thickness
The thickness of zinc (applicable to PPGI) or aluminum-zinc (applicable to PPGL) will affect the pricing. 20g zinc is cheaper than 50 zinc; It is suggested that 23-25 g zinc should be used in general. For PPGL, 25% aluminum is cost-effective for general environments, 55% for wet/tropical areas (better corrosion resistance).
4.2 Paint thickness and type
Single-coated PPGI is cheaper than double-coated (less paint). Type of coatings affect the cost: PE resin coatings are economical and widely used; Japanese/polyvinylidene fluoride/azonobel paints last longer, but their prices are higher. They are selected according to the needs of environment and durability.
4.3 Thickness of base material steel
Thinner substrates (0.13-0.16mm) cost more (more surface area, more paint/labor). Thicker substrates (0.45-0.7mm) have stable price and are economical and effective for most applications.
4.4 Packaging Form
Packaging choice: simple (short distance, low cost, waterproof paper), standard export (long distance, waterproof paper+galvanized iron sheet, steel wire reinforcement), special (vertical/customized, high cost due to materials/labor).
5. Main application scenarios of 60 color coated coil
Durable and versatile, 60g color coated coil (PPGI and PPGL) are widely used. The following are key applications recommended by coatings.
5.1 construction Industry
- Roofing/wall coating: suitable for residential/commercial/industrial buildings. PPGL (55% aluminum) is suitable for tropical/coastal regions; PPGI (23-25g zinc) is suitable for indoor/mild climates.
- Partition/ceiling: used for offices/shopping malls/factories. Single – coated PPGI (PE paint) is cost-effective.
- Precast Buildings: the key material of prefabricated/modular/temporary structures, which is easy to install due to its light weight.
5.2 Manufacture Industry
- Home appliance shell: used for refrigerator/washing machine/air conditioner. Double-coated PPGI (Nippon/PVDF paint) preferred for aesthetics and scratch resistance.
