Oak is widely distributed in the vast area of the northern hemisphere, with more than 300 varieties. Oak belongs to Fagaceae and Quercus. Oak is roughly divided into two categories: Red oak and white oak, but red oak is not red and white oak is not white. , The color distinction is not very obvious. The main point of the distinction is the difference between the tube holes and forest rays in wood science. For example, there is an infill in the tube holes of white oak. This characteristic makes white oak widely used in foreign countries to store wine. Oak is widely used in decoration materials, furniture materials, sports equipment, shipbuilding materials, vehicle materials, floor boards, etc. Slices of white oak and red oak are also ideal materials for the production of plywood. The patterns also have the difference between straight grain and horizontal grain. The straight grain is more beautiful and the price is slightly more expensive.
Characteristics of oak furniture:
Advantages:
1) It has a relatively distinct mountain-shaped wood grain, and the touch surface has a good texture;
2) The texture is solid, the structure of the finished product is firm, and the service life is long;
3) Higher grade, suitable for making European-style furniture
Disadvantages:
1) There are relatively few high-quality tree species, most of which are currently imported from Russia and the United States, and some are imported from Turkey, Austria, Germany and Canada. There are also many other regions in Europe and America, but the import volume is very small;
2) Usually imported oak boards have been strictly dried abroad and have good stability. Some manufacturers also import logs directly from abroad and cut and dry them by themselves. At present, the stability of oak furniture made by many professional oak furniture manufacturers in China is very high. However, due to the hard texture of oak, it is difficult to remove water. Furniture made without water may begin to deform or shrink and crack in a few years.
3) The phenomenon of replacing oak with rubber wood is common in the market. If the customer's professional knowledge is insufficient, it will directly affect the interests of consumers.
Red Oak
Widespread throughout the eastern United States. Oak is the tree with the largest number of species in the eastern hardwood forest. There are more red oaks than white oaks. There are many species of red oak, about eight of which are commercial trees. The white wood of red oak is white to light brown and the heartwood is pinkish brown. The appearance of red oak is usually similar to that of white oak, but because of the finer pith rays, there are fewer visible patterns. Most of the red oak is straight-grained and has a rough texture. Red oak gets its name from the fact that its leaves turn red in the fall. Red oak has good machinability; nails and screws well, although it is recommended to drill first; it gives a good finish after staining and polishing; it dries slowly and is prone to cracking and warpage; the shrinkage rate is large, and the performance is easy to change. Red oak is hard and heavy, with moderate flexural strength and rigidity, high breaking strength, and excellent steam flexural resistance.
Frequently Asked Questions about Red Oak
1. How is red oak different from other oaks?
The appearance of red oak is similar to that of white oak and European oak, but the heartwood has a pinkish tinge. Due to the wide area of growth of red oak, there is a big difference in structure and quality compared with white oak. This wood is rougher in grain and has finer hammer rays than the other two main varieties, resulting in a lighter silver streak than general oak. The various chromatic aberrations and textures of red oak provide designers with more choices. The processing properties of red oak (machining, nailing, screwing and finishing) are similar to those of white oak, but red oak has the best adhesion. In terms of structural use, red oak is stronger and harder than European oak, and its bending ability is stronger than that of white oak. Due to the many small pores in the wood of red oak, preservatives can penetrate more easily than white or European oak.
2. What is red oak best used for?
Best used for structural and non-load bearing building materials, furniture, flooring, interior architecture, interior joinery and moldings, doors, kitchen cabinets, paneling, coffins and boxes.
3. Can red oak be treated with preservatives?
Red oak can be treated with preservatives and is more permeable than white oak. Red oak absorbs more preservatives than other oaks. [Because treatability cannot be precisely defined, it is not possible to precisely classify wood treatability classes, especially for red oak heartwood treatability classes 2 and 3. These grades of wood typically exhibit irregular penetrations.
