Basically, plywood-made rock farms are not suitable for outdoor use due to their poor water resistance. Although the original construction cost of such rock farms is relatively cheap, some people have built them outdoors, but only have two or three years of service life. Therefore, the long-range calculation is still more expensive.
In addition, Fiberglass Reinforce Polyester Resin Compound, which is often used by manufacturers of artificial rock yards, although the basic material used by everyone is almost the same, the quality of its processing methods and the materials used are different. The big difference, the better manufacturers, will use sandwich processing methods, that is, one layer of glass fiber mats and one layer of resin are slowly piled up into rock plates, but some manufacturers only make a layer of glass fiber resin outside. Adding a layer of powder paint, of course, the relatively low cost and relatively poor strength, so you can often see this kind of light and thin rock board soon after assembly, the surface of the stone powder layer off and see the glass fiber layer inside, Simply distinguishing the advantages and disadvantages of this type of rock plate can be distinguished by looking at the weight of the rock plate per square meter. Basically, the heavier the unit area is, the better it is, indicating that this type of rock plate is multi-level processed and used. There are also more materials. Natural durability is higher and the service life is longer.
â–¡Small Tip â–¡
In order to compare the quality of the rock plates of various manufacturers, we can ask the manufacturers to send samples of rock plates first. From these samples we can see the advantages and disadvantages.
