Because veneer is a primary and natural product, it is difficult for the market to form a unified national standard for veneer. So even the grading standards among manufacturers in Linyi area are different. Generally speaking, veneers are divided into several main grades: A/B surface, C surface, secondary C, whole sheet, T-eye, dry scar, nail base A, and nail base B. Most plywood and particleboard manufacturers use the A, B, and C surfaces as the surface of the board, and use the second C, whole sheet, T-hole, dry scar, nail bottom a, and nail bottom b as the bottom of the multi-layer board. Due to differences in quality, the price also varies greatly. Even the prices between two adjacent factories have significant differences.
When trading, in China, it is generally calculated on a per sheet basis. Transactions with foreign clients are calculated on a per sheet basis or a per cubic meter basis. However, the most headache for buyers during transactions is not the price issue, but the quality issue. Because the dough is very thin and thousands of sheets are stacked together, it is difficult to conduct a comprehensive quality inspection. Some small businesses can be said to be small factories pursuing profits, but they have their own reputation by mixing some defective products into high-quality veneers. This is the most hated aspect in business. However, large-scale factories maintain good integrity in order to maintain their market, normal operation, and reputation. As the saying goes, small factories work hard, big factories make a name for themselves. That's the truth. So it is recommended that many buyers do not choose products with poor quality just for the sake of low prices. Don't lose big money just because of small money when running a business. For the quality of our products, we can spend a little more money to buy products with stable quality.
When it comes to quality, many buyers are not only concerned about the grade, but also about moisture. Many veneer manufacturers use earth kiln drying equipment, which means using fire for baking. This method can also dry the dough, but the moisture content is very uneven. In view of this, large-scale factories have adopted advanced drying equipment and used thermal oil for drying. This production line not only produces plywood with good flatness, but also has a relatively uniform moisture content.
