Hard and heavy, medium bending strength, poor rigidity, excellent steam bending resistance. Southern white oak grows faster, has wide rings, and the wood is hard and heavy. Heartwood has anti-corrosion ability, and the anti-corrosion treatment agent is very difficult to penetrate. White wood has medium anti-corrosion treatment agent penetration ability. USA: it is easy to get, but the supply is not as much as red oak. Export: the supply of boards and veneers of various quality and specifications is extremely sufficient. It is the most important Hardwood Export Product in the United States. Building materials, furniture, flooring, interior architectural design, outdoor joinery products, molded products, doors, cabinets, panels, sleepers, wooden bridges, wooden strips for wine barrels, coffins and buckets. It is widely distributed in the eastern United States, with hard and heavy wood, good machining performance and slow drying; The color, texture, characteristics and properties of red oak will change with the place of origin. Southern red oak grows faster than northern red oak, and the wood is harder and heavier. It is usually sold in the South and North according to the production area. The color of Southern wood is red and has color difference, which is suitable for darker coating products; The color of northern wood is light red and white, and the color is uniform. It is suitable for light color products, and the price difference between the north and the south is large.

Red oak

It is ideal to manufacture all kinds of furniture and cabinets. The wood is hard and tough, not too heavy, and easier to handle than other oaks. Unique wood grain and good surface treatment performance are ideal for making natural oil surface or dyeing products with the same color. Red oak components include solid wood, laminate and veneer. Furniture manufacturers all over the world use a large number of red oak plates and veneers in their products. The pink luster and multi-purpose characteristics of red oak floor are highly respected. It is hard and heavy, with high breaking strength and full seismic capacity, and can resist wear and tear. It is the best floor material for residential and commercial projects. Red oak solid wood flooring can be re polished and surface modified to increase its appeal and durability. The texture of red oak is usually vertical, rough and excellent after machining. Although the effect of fixing with nails and screws is good, it is recommended to drill first. After dyeing and polishing, it can create a beautiful surface. Red oak can provide wood slightly longer than the average length of other oak. These characteristics make red oak the most ideal material for building joinery.

a manchurian ash

The texture is clear. Solid wood furniture has won the love of many people with simple and rough line design and moderate quotation. What are the advantages and disadvantages of ash furniture? Large deciduous trees, up to 30 meters high, with a DBH of more than 1 meter; The bark is gray, the bark of young trees is smooth, and there are longitudinal cracks between thick and thin after maturity; Branchlets slightly quadrangular, glabrous, lenticels. The central area of Fraxinus mandshurica has a humid temperate monsoon climate. The soil is meadow ashing brown soil or raw forest soil developed on alluvial parent material. Manchurian ash is mainly produced in Northeast and North China. Landscape use: Court shade tree, street tree and landscape forest Fraxinus mandshurica are tough and beautiful in texture. They are deciduous trees, up to 30 meters high. They are precious timber trees in Northeast and North China. They can make all kinds of furniture, musical instruments, sports instruments, vehicles and ships, machinery and special building materials. At the same time, it is of scientific significance for the study of Tertiary flora and Quaternary glacial climate. It is a broad-leaved tree with hard material, straight texture and beautiful patterns. The diameter class of wood section is large, which is suitable for planing, printing and rotary cutting. The radial section shows beautiful parallel strip patterns, and the half chord printing surface shows obviously changeable strip patterns. It is generally high-quality veneer materials. In production, it is planed into slices (sheets) with a thickness of 0.8 ~ 1.0mm as veneer materials. Manchurian ash is mainly produced in Northeast and North China. Yellowish white (sapwood) or brown slightly yellow (heartwood). The annual rings are obvious but uneven, with thick wooden structure, straight texture, beautiful patterns, luster and high hardness. Fraxinus mandshurica has the characteristics of good elasticity, toughness, wear resistance and moisture resistance. But it is difficult to dry and easy to warp. Good processability, but tearing shall be prevented. The section is smooth and the paint has good adhesion. Processing performance: Fraxinus mandshurica has good processing performance. It can be well fixed with screws, screws and glue. It can obtain a good surface by dyeing and polishing. It is suitable for dry climate, with slight aging and small performance change. Physical properties: compared with its weight, Fraxinus mandshurica has very good overall strength, good earthquake resistance and steam bending strength. Durability: Fraxinus mandshurica has no heartwood corrosion resistance, and the white wood is easy to be eaten by powder beetles and common furniture beetles. Heartwood has medium anti permeability to anti-corrosion treatment agent, and white wood has permeability. Practicability: good flooring and furniture materials. It can imitate precious wood species such as Baiyuan, oak and walnut, and has high use value. It likes light, cold, fertile and moist soil, grows fast, has strong wind resistance, water and humidity resistance, strong adaptability, is more resistant to salt and alkali, and grows vigorously on moist, fertile and deep soil. It grows poorly in swamp areas and often forms "small old trees" on dry and barren soil.

Radial pine

The wood is high-quality soft wood with medium density, uniform structure, average shrinkage efficiency and strong stability. Intact logs are free from decay, heart rot, insect bite and other problems; The wood has good nail holding force, strong permeability, easy anti-corrosion, drying, curing and coloring.

Basswood

The material is slightly soft, the structure is slightly fine, the processing, finishing and cementation are good, it is not corrosion-resistant, and it is slightly warped when dry.

Elm

Beautiful pattern, coarse structure, good processability, finishing and gluing, poor dryness, easy to crack and warp.

toothed oak

Hard material, coarse structure, high strength, difficult processing, good coloring and finishing, poor adhesion, easy to dry and crack.

Maple

The utility model has the advantages of fine structure, easy processing, smooth cutting surface, good coating and gluing, and warpage when drying.
