Specify the most innovative liners on the market

In 2005, Ridge Corporation successfully introduced the refrigerated transportation market to the concept of welding the lower scuff band to upper wall liner walls to create a single piece, integral wall liner. Today, PolarX has established itself as the liner of choice when it comes to the safe, efficient transportation of temperature sensitive goods. Our patented process, utilizes high frequency sonic welders to connect the upper wall liner to the scuff below. The weld creates a durable, hermetic seal, protecting the underlying insulating foam from moisture intrusion and degradation, much more consistent than hot gas joining. At the interface, Ridge-welded seams have a higher strength than the surrounding materials.

Highest quality standards in the industry

The Ridge Integral Liner is manufactured to the highest quality standards in the industry. Our innovative product design combined with advanced materials and assembly processes sets us apart from the competition. Ridge has established a new benchmark in reefer wall performance.


Innovative product design combined with advanced
materials and assembly processes

Ridge panels incorporate the highest strength-to-weight Ratio in the market. In many cases Ridge scuff liners out perform aluminum scuff in puncture strength.
Ridge liners eliminate snag points that damage cargo. At the interface, Ridge welded seams have a higher strength than the surrounding materials. Caulk is not required for sealing seams that expand and contract at differing rates as in conventional aluminum and FRP construction.
Ridge ballistic-grade materials do not bend, dent, or deform into new shapes like traditional aluminum scuffs.
When the sealing properties of high-strength/high-pressure layered laminates are combined into one-piece wall design, out-gassing is nearly eliminated.
Hydrophobic, resists corrosion, mildew, degradation, and can be easily cleaned
