The แผ่นพื้นสำเร็จรูป treating approach makes use of pressure that forces the preservatives to the Wooden fiber. While you can find a variety of preservatives employed today, the production process is almost exactly the same for all.
When mixed, concrete is typically transported towards the location in which it is intended to become a structural product. Many ways of transportation and placement are employed depending on the distances involve, quantity required, along with other specifics of application.
