The labyrinthine grooves provide excellent sealing, and the panel wrapping around the grooves prevents damage, deformation, or detachment, while also increasing bending strength.
We have introduced the world's advanced Italian PUMA online automatic mixing and pouring technology and fully automatic cotton feeding system to produce PU/PIR cold storage panels featuring high strength, energy efficiency, environmental protection, sound insulation, fire resistance, and durability.
Ideal for any large or complex cold storage environment where precise, efficient, and flexible separation between different temperature zones is required. By creating multiple independent temperature zones within one building, it helps businesses achieve "one warehouse, multiple uses" and significantly improves operational efficiency.
We operate a modern smart manufacturing industrial park spanning 300,000 square meters, with an annual production capacity of several million square meters. We specialize in building envelope systems, including insulation and decorative building materials such as sandwich panels, cleanroom panels, and cold storage panels, as well as exterior wall cladding systems such as flexible clay tiles, metal carved panels, and integrated panels. The facility is capable of supplying materials to multiple large-scale projects simultaneously, thereby ensuring timely delivery.
We have introduced advanced continuous automated production lines from both domestic and international sources to achieve full-process automation, covering everything from steel coil uncoiling, roll forming, core material filling, and adhesive lamination to cut-to-length processing. The production process is monitored in real time by a central control system, ensuring high dimensional accuracy, consistent batch quality, and superior surface finish.
Our sandwich panel products possess core certifications including: fire safety performance test reports, EU CE certification, SABER certification, and BOMBSIRIM certification. Based on these certifications, our factory has also obtained ISO quality management system certification and SGS third-party authoritative certification. From the production process to the final product, it provides comprehensive quality assurance, helping sandwich panels comply with relevant regulations and be efficiently exported to global markets.
With 30 years of experience in export and manufacturing, we understand the usage standards and material quality requirements of different countries. We have a team of top-tier engineers and designers in the industry who provide seamless, one-on-one communication.
We offer six complimentary support services, all provided with sincere dedication: 1. Free design proposals; 2. Free renderings; 3. Free product test reports; 4. Free installation guidance; 5. Free technical support; 6. Free sample shipping.
We mainly provide PU sandwich panels, PIR sandwich panels, rock wool/slag wool sandwich panels, EPS sandwich panels, glass wool sandwich panels, paper honeycomb/aluminum honeycomb panels, magnesium-sulfur cement panels, etc.
Our standard MOQ for sandwich panels is 500 SQM. This standard is based on a comprehensive consideration of production line efficiency, raw material costs, and logistics arrangements to provide the most competitive pricing for both parties.
A standard order takes 15-20 days for production and 3-10 days for shipping. Please provide your specific requirements and we will provide you with a customized and precise schedule.
We provide a detailed installation manual and video guide, and we can send a technician for on-site guidance or provide the contact information of a professional installation team.
Our high-quality sandwich panels (galvanized steel + HDP/PVDF coating) have a service life of over 25 years under normal industrial conditions. All products come with a 10-15 year quality guarantee, and high-end PVDF products come with an additional performance guarantee.
Customers must submit feedback and provide evidence within 7 days of receipt. The factory will verify the information and then negotiate a solution (reproduction, reissue, compensation, etc.).
