In Canada’s harsh, snowy climate and demanding industrial warehousing requirements, Canglong Group’s PU panel for local clients’ steel structure warehouse projects have become the preferred solution for enclosure systems due to their core performance advantages, perfectly adapting to North American building standards and actual usage scenarios.


Exceptional Thermal Insulation for Frigid Climates: The PU (polyurethane) sandwich panel’s core insulation layer boasts a closed-cell rate exceeding 90% and a thermal conductivity as low as 0.022 W/(m・K), effectively blocking the conduction of extreme low temperatures below -30°C in Canadian winters, reducing energy consumption for warehouse heating. Simultaneously, it blocks high outdoor temperatures in summer, maintaining a constant temperature in the warehouse environment, significantly reducing the operating costs of air conditioning and heating systems, aligning with the core demands of the North American market for energy-efficient buildings.
Lightweight and High-Strength for Efficient Steel Structure Construction: The panels utilize a composite structure of color-coated steel sheets and a PU core material, with a unit weight only 1/5 that of traditional brick and stone materials. While meeting Canadian building wind and snow load standards (such as CSA S136 steel structure design standard), the load-bearing pressure on the main steel structure is significantly reduced. Prefabricated panels can be directly assembled on-site. Combined with the modular nature of the steel structure, construction efficiency is increased by more than 40%, shortening the winter construction period and reducing the impact of severe cold weather on project progress.
Long-lasting and Durable, Resistant to Diverse Environmental Erosion: The outer color steel plate is treated with fluorocarbon coating or aluminum zinc plating, possessing excellent resistance to ultraviolet rays, snow and ice erosion, and weathering, able to withstand the environmental challenges of different regions in Canada, such as the strong ultraviolet radiation in northern Canada and the rainy and humid conditions in the south. The PU core material itself is non-absorbent, mildew-resistant, and insect-proof, avoiding the performance degradation problems of traditional insulation materials caused by moisture. It effectively extends the lifespan of warehouse enclosure systems, reduces subsequent maintenance costs, and meets the long-term, stable usage requirements of industrial warehousing.
Fireproof and Soundproof, Balancing Safety and Comfort: The panels are UL/CSA fire-retardant certified in Canada. With the addition of flame retardants to the core material, its combustion performance reaches B1 level. When exposed to fire, it forms a carbonized layer to prevent the spread of flames, providing double protection for the safety of stored goods and personnel. Simultaneously, the porous structure of the PU core material provides excellent sound insulation, effectively blocking outdoor wind and snow noise and mechanical noise from industrial areas, creating a quiet working and storage environment inside the warehouse.
Green and Environmentally Friendly, Aligning With North American Sustainability Principles: The PU sandwich panel production process emits no harmful substances, and the core material is recyclable, meeting Canadian environmental standards for building materials. Its excellent thermal insulation performance reduces building energy consumption and carbon emissions, helping customers achieve sustainable development goals for green warehousing and enhancing the environmental benefits and social value of projects.
Canglong Group, with its deep adaptation to Canadian climate characteristics and building codes, uses high-quality PU panels as the core to provide local steel structure warehouses with… The integrated enclosure solution, which features thermal insulation and energy saving, safety and durability, and efficient construction, has become a reliable bridge connecting China’s intelligent manufacturing with the industrial needs of North America.
