Comparison of Sheet Types Used in Cold Room Panel Production
Comparison of Sheet Types Used in Cold Room Panel Production: PPGI, PVC, and INOX
In cold room panel production, the choice of cladding sheet is as critical as the insulation core. It impacts durability, hygiene, appearance, and panel lifespan. This article compares the three main types: PPGI, PVC-coated, and INOX.
🔹 1. PPGI (Pre-Painted Galvanized Iron)
What is it?
PPGI sheets are galvanized steel sheets that are coated with protective paint and cured in a furnace. They offer basic corrosion resistance and a wide range of color options.
Advantages:
Cost-effective.
Available in various colors .
Lightweight and easy to install.
Suitable for general food storage.
Disadvantages:
Limited resistance to chemicals.
Moderate resistance to physical impacts.
Common Applications:
General food cold rooms (fruits, vegetables, dairy, etc.)
🔸 2. PVC- Coated Sheet
What is it?
A galvanized steel sheet coated with a layer of PVC. This adds an extra level of protection against moisture, chemicals, and impact.
Advantages:
Highly hygienic and compliant with food safety standards.
Resistant to acidic cleaning agents.
Durable and impact-resistant.
Can be produced with anti-slip texture (used in floor panels).
Disadvantages:
May discolor slightly under prolonged UV exposure.
More expensive than PPGI.
Common Applications:
Meat, dairy, fish processing plants, pharmaceutical cold rooms.
🔹 3. INOX (Stainless Steel )
What is it?
Stainless steel (commonly AISI 304 or AISI 430) offers maximum resistance to corrosion, making it ideal for high-hygiene applications.
Advantages:
Top-level hygiene and easy cleaning.
Highly resistant to chemical agents and moisture.
Long lifespan, rust-proof.
Premium, professional appearance.
Disadvantages:
Significantly more expensive than other options.
Requires precision in cutting and welding during installation.
Common Applications:
Hospitals, laboratories, cleanrooms, seafood facilities, pharmaceutical warehouses.
🏁 Summary: Which Sheet Type is Right for Your Project?
| Sheet Type | Cost | Hygiene | Durability | Best for |
|---|---|---|---|---|
| PPGI | ⭐⭐ | ⭐⭐ | ⭐⭐ | General food storage |
| PVC | ⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐ | Meat, dairy, seafood |
| INOX | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Medical, pharma, high-hygiene |
When choosing the right sheet type for your cold room panels, consider your sector needs, hygiene requirements, and budget. A well-selected cladding material ensures longer panel life, better performance, and customer satisfaction.
