Food-Grade PE Coated PPGI Steel Coil Cold Storage Sandwich Panel 0.4-0.8mm Z180

Food-Grade PE Coated PPGI Steel Coil is a hygienic pre-painted galvanized steel coil developed for cold storage rooms, sandwich panels and clean industrial interiors. The product starts with a hot-dip galvanized steel substrate carrying a Z180 zinc coating for strong corrosion protection, then receives a food-safe chemical pre-treatment and a smooth polyester coating that forms a non-porous, easily washable surface. Because the paint film is continuous and free from pores, it resists moisture, condensation, cleaning agents and food residue, helping processors maintain hygiene and meet food safety requirements.

The smooth surface makes cleaning fast and reduces the risk of bacterial growth, while the galvanized and coated layers withstand the cold, humid and slightly corrosive conditions found in refrigerated warehouses and food factories. The coil is easy to cut, bend and laminate into insulated sandwich panels, so it is a practical facing material for cold room walls and ceilings, refrigerated truck bodies and hygienic processing partitions. Each coil is produced to international colour coating standards and is supplied with a mill test certificate for traceability.

• Food-Grade and Hygienic: A non-porous, easily washable polyester surface resists moisture, food residue and cleaning chemicals for food-safe cold store interiors.
• Cold Storage and Sandwich Panel: Optimised as the facing material for insulated cold room panels, refrigerated warehouse walls and hygienic processing partitions.
• Strong Corrosion Protection: A Z180 hot-dip zinc coating plus primer and topcoat withstand the cold, humid conditions of refrigeration and food processing environments.
• Smooth Easy-Clean Surface: The continuous paint film has no pores or crevices, so walls and ceilings are quick to clean and stay hygienic over long service.
• Good Formability: The ductile substrate and flexible coating allow cutting, bending and profiling into sandwich panels without cracking the paint film.
• Certified and Traceable: Produced under ISO 9001 management with SGS inspection and a mill test certificate covering coating weight, thickness and mechanical properties.

Food-Grade PE coated PPGI steel coil is used as the facing material for cold storage room panels, refrigerated warehouse walls and ceilings, refrigerated truck and container bodies, clean room partitions and hygienic processing rooms. It is also suited to food factory wall cladding, slaughterhouse and dairy plant interiors, beverage and bakery production halls, and pharmaceutical cold chain facilities. Wherever a washable, hygienic and corrosion resistant metal surface is required at low temperature, this coil provides a durable and easy to maintain solution.

Q: What is food-grade PPGI steel coil used for?
A: It is used as a hygienic facing material for cold storage panels, clean rooms, refrigerated warehouses and food processing interiors that must be easy to clean.

Q: Is PPGI suitable for cold storage?
A: Yes. With a Z180 zinc coating and a smooth polyester film, food-grade PPGI resists the cold and humid conditions of refrigerated and food processing environments.

Q: Can the surface be cleaned easily?
A: Yes. The continuous, non-porous paint surface resists moisture and food residue and can be wiped or washed with standard cleaning agents.

Q: What thickness is recommended for sandwich panels?
A: For cold storage sandwich panels, 0.4 mm to 0.8 mm thickness with a Z180 coating is typical, balancing strength, weight and cost.

Each coil is wrapped with PE film and waterproof paper, secured with steel strapping and loaded onto fumigated wooden pallets for ocean transport. Every coil is labelled with grade, zinc coating weight, colour, thickness, coil number and weight for full traceability. We supply mill test certificates, SGS inspection reports and pre-shipment photographs on request, and our ISO 9001 certified process ensures consistent hygienic quality. Sample coils and colour chips are available for approval before mass production.
