Firstly, clarify the purpose of wood. We need to distinguish between two situations: civilian (including public) site applications or industrial production basic machinery and equipment applications. Civil and public areas are areas that are often touched by people, such as children's playgrounds, children's playground equipment, etc. It is necessary to use anti-corrosion wood with high safety levels and environmental protection effects. At the level of basic machinery and equipment for industrial production, on the premise that they do not harm the natural environment, the selectivity of log materials may be more extensive.

Subsequently, learn about the natural environment and quality standards that wood and lumber should meet when applied. Be aware of the requirements of the application location and natural environment. There are generally three situations for the application of log materials: indoor or outdoor, above or below ground, and in water or seawater. The same product requires different levels of corrosion protection in different applications, understanding its relative biological hazard level, and then deciding to choose different levels of wood and wood.

In the standard GB/T22102, the natural environment level for the application of wood and wood is divided into six categories, and the natural environment for application is standardized. Typical uses are cited, and the two overall goals related to the quality of wood veneer materials, namely the penetration rate and loading dose, are classified and detailed. Customers should have a general understanding of the above content before purchasing wood and choose a relatively high level of anti-corrosion wood products based on their detailed application in the natural environment.

Z finally understands the work ability and social development credit of wood and lumber production manufacturers. The investigation of the credit rating of manufacturers is also particularly important. Wood is a long-term product that cannot be judged in the short term (a few months or 1-2 years). When choosing, it is advisable to choose brand enterprises with large production and operation scale, complete types, and high reputation in China. For each batch number and standardized product, inspection explanations should be obtained from technical professional inspection institutions.

The customer also learned that due to the limitations of the inherent characteristics of wood and wood, its products are heterogeneous. The data information on inspection explanations only indicates the quality of a certain batch number and standardized products, which does not necessarily mean the quality of all anti-corrosion production enterprises' products. It is understood that many production enterprises and suppliers nowadays often suffer from diseases when one inspection statement is used for one year or another year. In such scenery, it is difficult to ensure the quality of goods, and it will ultimately be the customers who suffer. Therefore, in terms of inspection and approval, attention should be paid to verifying the production batch number and specifications of the product, and the key points should be highly valued to determine the application level of such products.

The tested sample is a factor that endangers the inspection results. Some illegal merchants fabricate from it, and re inspect high-quality samples to obtain a considered inspection explanation. The relevant customers are counterfeit and inferior. We believe that customers can choose independent sampling inspection or conduct sampling inspection according to technical professional inspection agencies for the required products, and send the individual samples obtained from the sampling inspection to the relative inspection agency for inspection, appropriately evaluating the quality of the products. Generally speaking, the entire inspection process will be completed within a week, and the costs incurred can also be borne by the supplier. Regarding the selection of inspection institutions, it is believed that third-party technical professional institutions with Chinese qualifications should be selected.
