Streamlined Manual Panels for Optimal Productivity

Short Description:

Advantage of Dong`an Manual panels

A: Our cold storage panels have strong deformation resistance, are not prone to cracking, and are much more stable.

B: The thermal conductivity coefficient is lower, usually between 0.019 and 0.022w/mk (25) for the core board, while our cold storage board can have a thermal conductivity coefficient of 0.018. The thermal conductivity coefficient is low, and the insulation performance is higher. In addition, our cold storage board has a moisture-proof and waterproof system function.

C: Featuring fire resistance, flame retardancy, high temperature resistance, and good sound insulation effect

Overall advantages: One stop purchase come from Dong`an.
