9-Layer Painted Galvanized Steel Cross-Section Anatomy
Hot-dip galvanized steel facings (EN 10346) feature a 9-layer protective coating system engineered for high-humidity cold rooms and hygienic washdown environments:
Peelable polyethylene/PVC protective film that shields the pre-painted coil surface against scratches, handling marks, and mortar splashes until installation is complete.
Hygienic 25 µm polyester or 100–200 µm PVC/Plastisol top coat engineered for HACCP food contact safety, UV stability, and chemical washdown resistance.
Flexible corrosion-inhibiting primer layer that anchors the top coat with high adhesion and prevents micro-cracking during roll-forming.
Chemical conversion coating that passivates the zinc surface against white rust and oxidation while activating surface bonding.
Hot-dip zinc metallic coating that provides sacrificial cathodic protection to the structural steel core in high-humidity cold rooms.
High-yield 0.50–0.60 mm structural steel core (or optional AISI 304 stainless steel) delivering impact resistance, wind/snow load capacity, and self-supporting ceiling span strength.
Hot-dip galvanized zinc layer protecting the foam-facing underside of the steel sheet against vapor diffusion and internal corrosion.
Inner chemical conversion layer that stabilizes the lower zinc coating and prepares the surface for primer adhesion.
Specially formulated primer ensuring uniform, permanent bonding between the passivated steel and the back coat.
Chemical back coat that forms a cross-linked molecular bond during the exothermic 40–42 kg/m³ PUR/PIR reaction, preventing delamination under severe ΔT thermal shock.

Frequently Asked Engineering & Supply Questions
Frequently asked technical questions regarding cold room doors, panel thickness selection, thermal sealing details, and turnkey project workflows.
C11 Which cold room panel thickness should be selected for each operating temperature regime?
General engineering guideline: 60–80 mm for +8/+15°C cool storage, 80–100 mm for +2/+8°C chillers, 100 mm for 0/+4°C fresh storage, 120–150 mm for -18/-22°C freezers, 150–180 mm for -25/-30°C deep freeze, and 180–200 mm for -35/-40°C blast freezers.
C12 What is the main difference between PUR and PIR insulated cold room panels?
Both provide high thermal insulation at 40–42 kg/m³ density, while PIR (Polyisocyanurate) features an enhanced isocyanurate ring structure that delivers superior fire resistance, reduced smoke emission, and compliance with industrial property insurance standards.
C13 What is the difference between Cam-Lock modular panels and continuous-line slip-joint panels?
Cam-lock modular panels allow rapid assembly and future disassembly/relocation for walk-in cold rooms. Continuous-line labyrinth slip-joint panels are engineered for tall industrial cold storage buildings and long partition walls up to 13.5 meters.
C14 Why is floor insulation critical in cold rooms and freezer chambers?
Without proper floor insulation in sub-zero rooms, ground moisture freezes and expands (frost heave), cracking the concrete slab. Modular rooms use birch-plywood + stainless steel floor panels, while forklift-rated warehouses use multi-layer high-compressive XPS/PIR below a reinforced concrete slab with underfloor heating or ventilation.
C15 Why are hygienic cove skirtings and rounded internal/external corner profiles (A02) required?
Sharp 90-degree wall-to-floor and wall-to-wall angles trap bacteria and organic residues. HACCP, IFS, and BRCGS food safety audits require coved (rounded radius) PVC/aluminium hygienic profiles for effortless sanitation.
C16 Which cold rooms require a pressure relief valve (A03)?
Rapid air contraction after door closure or defrost cycles creates strong vacuum pressure inside sealed rooms. Heated pressure relief valves are mandatory in all sub-zero freezers and blast rooms to prevent panel implosion and vacuum-locked doors.
