The multi-layer solid wood floor is a plywood structure. Its surface layer is made of precious wood by rotary cutting into thin wood. The substrate under the surface layer is made by cutting ordinary wood into thin slices, making it crisscross, multi-layer combination, and then using environmentally friendly waterproof adhesive. The multi-layer sheet is compounded by high temperature and high pressure, and the wood fibers are arranged in a net-like superimposed manner. The structure is very tight and the performance is specific and stable. It completely overcomes the shortcomings of natural materials that are easy to deform.2.Percentage ABC Grade: Percentage of grade AB: 15%, Percentage of grade C: 85%; ABCD Grade: Percentage of grade AB: 20%, Percentage of grade C: 50%, Percentage of grade D: 30%3.Picture
1.1.The Engineered Flooring first layer is usually with UV coating of natural oil. 1.2.The second layer is the hardwood top layer and it is also called veneer layer and it can be oak, walnut, maple, birch, etc. And the veneer thickness is usually 2mm, 3mm, 4mm, etc. 1.3.The third layer is the plywood core layer and this layer uses different species of veneers forming plywood, such eucalyptus, poplar, birch. 1.4.The fourth layer is the backing layer and it is to provide stability to the board and its species is usually poplar.2.Specifications| Wood Flooring species: | Oak, Maple, Birch, Cherry ,Teak, Ash, Rosewood, Walnut, etc. | |

Multi-layer solid wood flooring is a new type of flooring between solid wood flooring and laminate flooring, and is a new trend in floor purchase. Multi-layer solid wood flooring retains all the advantages of natural solid wood flooring. It not only has the natural texture and elasticity of solid wood flooring, but also overcomes the common problems of natural solid wood flooring that is easy to swell and shrink. It has the characteristics of anti-deformation, corrosion resistance and easy cleaning.
The surface layer of the multi-layer solid wood floor is coated with paint several times, so that the paint penetrates into the voids of the wood structure, and infrared radiation, electronic rays and thermal radiation are added to form a whole in the wood structure, so that the wood is hardened. Therefore, the multi-layer solid wood floor is not easy to be polluted, not easy to be scratched, has strong wear resistance, and can maintain the beauty of new materials and the texture of solid wood for a long time.
Finally, select the intrinsic quality, which is a key indicator of multilayer solid wood flooring. It can be seen from the water absorption thickness expansion rate that its waterproof and moisture-proof performance, the lower the better, the best is less than 2%, followed by less than 5%. Pyrotechnics are burned on the surface. If there are no traces, the fireproof coefficient is higher. The formaldehyde content is an index that cannot be ignored. According to national regulations, the formaldehyde content per 100g floor shall not exceed 9mg. "Three-point floor and seven-point installation", so it is recommended to choose DEGE brand flooring when choosing multilayer solid wood flooringDue to the multi-layer glue compound, the multi-layer solid wood floor has good waterproof performance and can be used in wetter floors and areas. Multi-layer solid wood flooring has been treated with insect-proof treatment, and environmentally-friendly glue is used, which can effectively prevent insect damage and is non-toxic to humans.
Practice has proved that the foot comfort of multi-layer solid wood flooring is the same as that of natural solid wood flooring, and the paving method is basically the same. Due to obvious advantages, its market usage is gradually increasing. When choosing a multi-layer solid wood floor, you must first choose the appearance quality. It depends not only on whether the color, texture and paint quality of the surface wood meets the grade standard, but also whether there is decay, dead knots, knot holes, worm holes, sandwich resin capsules, Wood defects such as cracks or loose joints, the wood texture and color perception are harmonious, the paint should be uniform, no bubbles, small white spots, etc., and the surface should not be damaged by obvious stains. While choosing the appearance, you should also observe whether the tongue and groove around the floor are complete.
Secondly, choose whether the size of the product is consistent with the length, width, and thickness of the size you purchased, and then check whether the dimensional tolerance of the product is consistent with the purchased grade. The measurement method can take multiple pieces of floor in the same packing box and assemble it by yourself. After assembling, observe whether the tenon and groove are tightly combined. At the same time, you can touch the floor after splicing to see if it is irregular. If there is a prominent hand feeling phenomenon , Indicating that the product is unqualified. After touching it by hand, pick up two assembled multi-layer solid wood floors and shake them in your hands to see if they are loose.
