Do you know how to choose a right roof and wall material for steel structure building?
Generally, there're 4 different kinds of materials-EPS sandwich panel,rock wool,fiber glass wool and PU sandwich panel.
The cost varies from panel to panel according to their performance.
When choose material, you need to take performance into consideration, not only focus on cost.
Here is the specification for your reference.
