Key Engineering & Commercial Benefits
Eccentric Cam-Lock Fasteners
Internal foamed-in steel hook locks compress joint gaskets hermetically without through-screws.
Double-Labyrinth Tongue & Groove
Stepped labyrinth profile completely eliminates thermal bridges between cold interior and warm exterior.
HACCP Food-Safe Antibacterial Surfaces
Certified 120µm antibacterial PVC film or AISI 304 Stainless Steel withstands aggressive sanitizing detergents.
40-42 kg/m³ High-Density Core
Maximum density closed-cell polyurethane matrix drastically reduces refrigeration compressor run-hours.
Available Systems & Models
Select the optimal profile and core configuration for your building envelope requirements.
Engineered with factory-embedded eccentric cam-locks or precision double labyrinth joints to ensure airtight seals, eliminating energy losses in cold rooms from +4°C down to -40°C.
Suspended ceiling panels equipped with aluminum T-profiles and thermal-break tie rods to support ceiling loads while preventing condensation and frost formation.
High compressive strength flooring designed to withstand static and dynamic rolling wheel loads while eliminating ground frost heaving.
High-frequency industrial cold doors engineered with anodized aluminum hardware, safety inside-release pushbars, and perimeter heating cables to prevent seal freezing in negative temperature chambers.
Sanitary curved PVC coving profiles eliminate 90-degree internal corners between floors, walls, and ceilings in cold rooms and food facilities. Certified to international HACCP standards, they prevent bacterial growth, facilitate high-pressure washdown, and ensure zero dirt accumulation.
Designed specifically for -40°C blast freezing tunnels and commercial sub-zero preservation, these panels incorporate an extended double-stepped labyrinth edge profile combined with heavy-duty internal eccentric cam-locks, preventing thermal leakage under extreme temperature differentials.

Critical Engineering Guidelines for System Selection
Standards for purlin spacing, live loads, fire containment and joint detailing.
1. The Eccentric Cam-Lock Fastening System
Cam-lock panels feature factory-foamed male/female eccentric hook locks operated by an Allen wrench. Turning the lock draws panels tightly together, compressing internal gaskets to form a hermetic vapor-tight seal. Panels can be disassembled and relocated without damage.
2. Hygienic Food-Safe Surface Coatings (PVC, Inox, Plastisol)
Standard coils deteriorate under heavy detergent washdowns and chemical sanitizers. We laminate panels with certified 120µm Food-Safe antibacterial PVC or AISI 304/316 stainless steel to comply with global HACCP food-contact directives.
3. Subfloor Frost-Heave Prevention & Heating Mats
Sub-zero temperatures freeze groundwater beneath foundation slabs, causing destructive frost-heave swelling. Installing underfloor electric heating cables or PVC ventilation pipes under dual-layer high-load XPS insulation protects civil foundations.
4. Pressure Relief Valves for Sub-Zero Thermal Shocks
Opening cold room doors introduces warm air that rapidly contracts, generating intense vacuum forces. Electrically heated pressure relief valves equalize internal barometric pressure, preventing wall structural collapse and door jam.
5. Ceiling Panel Suspension Engineering (T-Profiles & Rods)
Large cold ceiling spans require intermediate suspension. Threaded M12 tie rods dropped from primary roof trusses anchor heavy-duty powder-coated aluminum T-bars, preventing ceiling panel sag over long service lives.
6. Curved PVC Hygienic Covings & Sanitary Detailing
Right-angle corners harbor bacterial biofilms and resist pressure washdowns. Radius-curved sanitary PVC covings transition floor-to-wall joints smoothly, meeting stringent veterinary and food hygiene inspections.
Matching Flashings, Screws & Trims Package
Coordinated single-delivery guarantee: Color-matched flashings, EPDM fasteners, and covings.

Sliding & Hinged Cold Room Doors
Monoblock polyurethane doors with perimeter heaters and internal safety release.
Heated Pressure Relief Valve
Balances interior atmospheric pressure in freezers to prevent wall deflection.
Wiremesh Non-Slip Floor Plywood
High-durability birch plywood withstands pallet truck traffic and humidity.
