Application Scenarios

Project

This food manufacturing plant in Poland adopted our PU sandwich wall panels as exterior enclosure. Total panel area reaches 8,200 m² and finished construction in 2019. The 100mm PU core panels deliver outstanding thermal insulation and air-tight performance, minimizing cold bridging and stabilizing indoor temperature for food production workshops. The panels meet European EN standards, resisting humidity and corrosion in temperate climate. Fast onsite assembly greatly shortened construction cycle for this industrial building.

Customization & OEM Service

Dimensions, thickness and RAL color are customizable. Automated line keeps batch quality stable; light weight cuts installation labor.

Certifications & Compliance

All PU sandwich wall panels are backed by integrated ISO system certifications, with raw steel sheets tested to EN specifications. Our certified production ensures consistent thermal performance and structural safety for industrial & commercial building walls.

After-Sales Service

Online technical support and remote installation guidance are provided. For product-quality issues we offer compliant replacement and technical solutions. Dedicated follow-up covers pre-sales selection, in-production progress updates with packing photos, and post-delivery troubleshooting.
