Building construction sites are mainly used for construction sites. The building formwork is also a kind of plywood. Generally, it is made of two or three grades of veneer raw materials, and the template glue is used (the formaldehyde release is relatively high, but the bonding strength is good)
Layered and layered, high-grade building templates will also use good raw materials and glue (such as phenolic glue). The cost is relatively high and the number of cycles can be more. It is generally used for bridge construction or other high-demand buildings. .
