PPGL AZ150 Trapezodial Steel Tiles PVDF Sherwin-Williams 40-Years Warranty Residential Building Roof Sheet PPGI Z180

1. Product Category

Color coated plates combine the benefits of organic polymers and steel, offering a unique blend of properties that make them highly versatile and valuable in various applications. They feature the colorability, formability, corrosion resistance, and decorative qualities of organic polymers, along with the high strength and ease of processing of steel. This combination enables these plates to be easily punched, bent, deep-drawn, welded, and processed in other ways, making them practical, decorative, and durable.

Color coated sheets come in a vast array of over 600 varieties, but due to the diversity and lack of a unified classification system, they are generally categorized based on customary practices. Each manufacturer may have unique equipment, technologies, and product varieties, further complicating standardized classification. Here, we outline the general categories for clarity.

2. Types of Color Steel Tiles

1. Corrugated Steel Tiles

- Description: These are traditional roofing sheets with a wavy pattern, offering good water drainage and aesthetic appeal.

- Applications: Used for industrial, commercial, and residential roofing.

2. Trapezoidal Steel Tiles

- Description: Featuring a trapezoidal shape, these tiles provide excellent strength and durability.

- Applications: Ideal for industrial buildings, warehouses, and large commercial structures.

3. Tile-Effect Steel Tiles

- Description: Designed to mimic the appearance of traditional clay or concrete tiles while providing the benefits of steel.

- Applications: Popular in residential buildings and commercial buildings for aesthetic purposes.

4. Standing Seam Steel Tiles

- Description: These tiles have a raised seam running vertically up the roof, providing a sleek, modern look and superior weather resistance.

- Applications: Used in contemporary residential buildings and high-end commercial projects.

5. Sandwich Panel Steel Tiles

- Description: Composed of a core insulating layer sandwiched between two steel sheets, offering excellent thermal and acoustic insulation.

- Applications: Used in cold storage, warehouses, and buildings requiring temperature control.

3. Color and Paint Systems for Color Coated Steel Sheets Used in Cold Storage

1. Color Selection

Common Colors:

- White: White is a common choice for cold storage facilities due to its reflective properties, which help in maintaining a consistent internal temperature and enhancing brightness.

- Light Blue: Light blue is also used for its aesthetic appeal and reflective qualities, which contribute to a cooler interior environment.

- Silver: Silver or metallic finishes can be chosen for their high reflectivity and modern appearance.

Color Considerations:

- Reflectivity: Lighter colors are preferred as they reflect more light and heat, helping to maintain cooler temperatures inside the facility.

- Aesthetics: The color may be selected based on the facility's design requirements or branding.

2. Paint Systems

Common Paint Systems:

- Polyester (PE): Polyester coatings are commonly used for cold storage applications due to their durability, cost-effectiveness, and good resistance to chemicals and weathering.

- Silicon Modified Polyester (SMP): SMP coatings offer enhanced hardness, better heat resistance, and improved outdoor durability compared to standard polyester coatings.

- Polyvinylidene Fluoride (PVDF): PVDF coatings are known for their exceptional weather resistance, chemical resistance, and long-term color stability. They are less common due to their higher cost but are preferred for high-performance applications.

Paint System Features:

- Thermal Reflectivity: The paint system should have good thermal reflectivity to aid in temperature control within the cold storage facility.

- Chemical Resistance: Paint systems should be resistant to chemicals and moisture to prevent degradation over time.

- Ease of Cleaning: The paint should have a smooth surface to facilitate easy cleaning and maintenance.

3. Steel Material Specifications

Steel Grades:

- Pre-Galvanized Steel: Often used for its good corrosion resistance, especially when combined with appropriate paint systems.

- Hot-Dip Galvanized Steel: Provides an additional layer of protection against corrosion, suitable for harsh environments.

- Aluzinc (Galvalume) Steel: Offers superior corrosion resistance compared to pure zinc, providing long-term protection for cold storage applications.

Material Requirements:

- Strength and Durability: Steel used should have high tensile strength to withstand the structural demands and potential impact during installation and operation.

- Corrosion Resistance: The steel must be resistant to corrosion, especially in environments where moisture and temperature fluctuations are prevalent.

- Thickness: The thickness of the steel sheets should be appropriate for the structural requirements and insulation needs of the cold storage facility. Common thicknesses range from 0.4 mm to 0.8 mm, depending on the application.

Additional Considerations:

- Pre-Treatment: The steel should be pre-treated to improve adhesion of the coating and enhance its performance against corrosion.

- Compatibility: The steel and coating system should be compatible to ensure the longevity and effectiveness of the protective layer.

Summary Table

By selecting appropriate colors, paint systems, and steel grades, cold storage facilities can achieve optimal performance, durability, and aesthetic appeal, ensuring the efficient operation and longevity of the storage environment.
