Why choose 60 G color coated coil? Everything you need to know about high quality coated steel

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/).

2. The unique advantages of 60 G color coated coil

Runfei’s 60 g color-coated coil has unique competitive advantages in the coated steel market, based on strict quality control, customer-centered services and cost-effectiveness.

Strict production quality control to ensure zero compensation. The coil has passed ISO 9001/SGS/RoHS certification and its performance is stable under harsh conditions.

2.2 cost-Effective Pricing with Premium Services

Factory direct pricing of trade-grade services provides competitive costs without loss of quality. Small trial orders are accepted for SMEs or pre-large-purchase testing.

2.3 Multiple packaging options

Standard seaworthy packaging (horizontal/vertical) can meet all kinds of transportation needs: horizontal packaging is used for regular transportation, and vertical packaging (pallet fixing) is used for long-distance/fragile transportation, and complete delivery is ensured through waterproof/shockproof design.

3. Product Specifications of 60 G Color Coated Coil

Understanding specifications is key to choice. The following are key details: standards, origin, certifications, coating and substrate parameters.

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.
• Furniture/decoration: used for frames/shelves/panels, and customized colors/paints to match designs.
• Auto Parts: for internal/external use; For outdoor exposed parts, it is recommended to use PPGL.

5.3 Infrastructure and agriculture

• Warehouse/workshop structure: the standard export packaging can protect the coiled material during long-distance transportation to construction sites.
• Agricultural Greenhouses: an ideal choice of frame/cover. PPGL (55% aluminum) is recommended for wet/coastal areas (resistance to moisture/pesticide corrosion).
• Fence/guardrail: durable coating ensures long-term outdoor performance.

6. Step-by-Step Guide to Selecting the Right 60 G Color Coated Coil

Follow this guide to select the right 60G color coated coil:

1. Determine the application environment: indoor/outdoor, exposed to humidity/salt fog/extreme environment, select PPGI and PPGL, coating thickness and paint type.

2. Determine Substrate Thickness: Based on structural needs (load-bearing/rigidity); 0.3-0.45 mm has a high cost performance in most cases.

3. Choose coating Type: PPGI (23-25g zinc) is suitable for indoor/mild climates; PPGL (55% aluminum) is used in harsh environment.

4. Selection of paint type/thickness: single/double coatings are selected according to durability; General purpose PE paint, high durability Nippon/PVDF.

5. Determine the packaging: simple (short distance), standard export (long distance) and special (fragile/customized).

7. Frequently asked questions about 60 G color coated coil

Q 1: What is the difference between PPGI and PPGL of 60g color coated coils?

A 1: The core difference is the metal coating: PPGI (pure zinc) and PPGL (aluminum-zinc alloy, which has better corrosion resistance in harsh environment). The aluminum content in PPGL is 25% /55%; The price of PPGI depends on the thickness of zinc.

Q 2: What is the recommended type of paint for outdoor applications?
