FAQ 

1. What is the thickness of the color plate?

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 ZJT brand, which are too weak. 

2. For PU panels, the higher density the better insulation, right?

No. The best density is 42kg/m3. We can do the 42kg/m3 to ensure the best insulation.

3. If PU panel add flame retardant, what will cause?

Flame retardant is bad materials. It will cause the dense smoke and poor insulation. 

4. Why the price difference is so big in MIC?

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- Bao-steel brand color plate and high density-42kg/m3. 

What is the warranty for the PU panels?

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. 

What is thickness of PU panel?

50/ 75 /100 /120/150/180/200 mm

Can the PU size be customized?

The length of PU panel can be customized. The standard width is 960 mm

What is the difference between EPS panel and PU panel?

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.
