Features
Our PU panel use best PU foam brand Wanhua. What' s more, we can guarantee 42kg/m3 high density, while others produce low density PU panel. It will influence the cold room life time.
2. Zinc-coated cam lock, stronger
Our zinc coated cam lock, it is different than other zinc-coated cam lock, the color is clear and no rust even when you use 10 years. Zinc-coated layer is very thick.
3. B2 Fireproofing PU panels, no risks.
Our PU panel foam use polyester that reach B2 fireproof grade. It is difficult to burn and without smoke. While other supplier add fire retardant into PU foam, it will generate smoke when it happen fire.
4.Best steel manufacturer, Baosteel
Compare with those 0.326, 0.426mm color steel, Baosteel is more durable and anti-corrosion.
Guarantee your cold room use for at least 20 years!

FAQ
ZJT brand color plate: 0.5mm, 0.6mm, 0.8mm. The Bao-steel brand is the best in China. Other supplier may use 0.326mm, and 0.426mm, not Bao-steel brand, which are too weak.
No. The best density is 42kg/m3. We can do the 42kg/m3 to ensure the best insulation.
Flame retardant is bad materials. It will cause the dense smoke and poor insulation.
The cold room market is so competitive in Alibaba. Some supplier focus on the price, and some focus on the quality. We only do the high quality cold room. All our panels are designed based on 20 years life time ZJT brand color plate and high density-42kg/m3.
We can grantee you 3 years warranty and design the PU panels used for 20 years. Compared with suppliers, some give 1 year warranty, some even no warranty grantee.
50/ 75 /100 /120/150/180/200 mm
The length of PU panel can be customized. The standard width is 960 mm
EPS and PU panel all have thermal insulation function, but EPS insulation ability is not good, without zinc-cam lock, easy to break out. In general, most cold room use PU panel now.
