Jinhongtong Group presents the JHT-SWB-IS50, a Energy-saving steel warehouse building with rock wool and EPS sandwich panel wall and roof system for cold storage. Engineered with high-strength steel and manufactured under strict ISO 9001 quality control, this building combines structural reliability, fast construction and long service life, making it a preferred choice for Europe energy efficiency buyers worldwide.

• Rock Wool Fire-Safe Core: Rock wool sandwich panels achieve A2/B1 fire ratings, protecting inventory and personnel in Europe energy efficiency facilities.
• Energy Saving Envelope: U-values from 0.28 to 0.45 W/m2K cut heating and cooling energy consumption by up to 40 percent.
• Condensation Free Design: EPS and PU panels with EPDM seals prevent moisture ingress and internal condensation year-round.
• Cold Storage Ready: JHT-SWB-IS50 supports controlled temperature operation from -20 deg C to +40 deg C for cold chain logistics.
• Clean Aesthetic Finish: Factory-laminated flat panels provide a smooth, modern appearance with concealed fastener detailing.
• Rapid Cladding Installation: Self-tapping screw fixing with pre-punched panels accelerates wall and roof closing significantly.

Typical applications include cold storage warehouses, food processing plants, pharmaceutical distribution centers, data centers and energy-efficient industrial facilities. The high-performance building envelope maintains stable interior conditions while dramatically reducing energy bills.

For European clients, the sandwich panel system supports passive-house style insulation targets and complies with EU energy performance directives, with optional certification documentation for green building schemes such as BREEAM and LEED.

Jinhongtong operates 170 sets of advanced fabrication equipment, including large hydraulic press brakes, CNC drilling machines, large-scale shot blasting units and ultrasonic flaw detectors. Processing follows AISC 360, Eurocode 3 and EN 1090 standards, with strict raw material inspection, precision CNC cutting, professional submerged arc welding, and full visual and UT/MT non-destructive testing before delivery. This disciplined process ensures every member arrives on site with exact dimensions and flawless coating.

Sandwich panels are factory-laminated under controlled conditions, with protective film left on surfaces until installation. Panels are packed in export-grade crates with edge protection, and all seals, flashings and fasteners are supplied in labeled kits.

Thermal performance test certificates and fire rating documentation are included with every shipment, supporting local building permit applications. The complete building carries a 10-year structural warranty.
