Excuse me, how much is the material per square meter for the 50-thick foam sandwich panel roof (0.5mm thick on the color steel plate and 0.5mm thick on the bottom)? How much is it including tax? How much is it without tax? You can't buy 0.5-thick foam board 55. Even if it is really 55, it is also cutting corners. The basic price is around 65, excluding tax, which is more expensive if steel plates are included. There are also corrugated boards commonly used in roofing, which are more expensive. Between 72 and 75, as required. We are all from Suzhou here. You can contact
