2.Core material description:

Rockwool is A level fireproof core material for sandwich panels,but this kind of material is afraid of water,so no matter it's production, delivery, or installation,we all need to take note for waterproof problem for rockwool material.Our thickness for rockwool is 50, 75, 80, 100, 150, 200mm,and density range is 80 - 150 KG/M³.
 

3.Material warranty:

Our steel sheets cooperating partners are Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel,etc.Rockwool raw material is our branch factory made it.

4.What effects on panel lifetime?

1. Steel brand: Good steel brand could make sure good zinc and color coating,which avoid color fading;
2. Need to choose the suitable coating type for your project,according to your local climate features;
3. Need to do regular inspection and maintaince per 6 months.

Material tolerances:

7.How to cut insulated panels and flashings?

☆ Suitable tool:
Use a clean tooth blade saw to cut the metal sandwich panels;
Use angle grinders to avoid panel guarantee;
Use hand snips to cut steel flashings.
☆ Keep clean:
Please remove all metal scrap,after cutting,to avoid metal panel getting rusty.
Please prevent sparks and filings from falling onto other panels.
