What is Douglas fir preservative wood?

Douglas fir wood preservative wood that is later treated by artificial wood, the use of raw materials for the southern United States
Douglas-fir wood preservative in the industry among its elegant appearance of the color, texture highlights, material properties of the unique and reliable, and so on.
Related advantages by the industry many new and old customers of praise, is the home of outdoor, landscape architecture among the ideal use of materials.

Advantages of Douglas Fir wood:

First, Douglas fir wood preservative raw materials for the United States Douglas fir, Douglas fir in the United States is known as the 'super structure timber', high hardness, compression and bending performance

Good, dry shrinkage expansion uniform, very suitable for use in construction, not because of its harsh environment, resulting in cracking and fracture.

Second, Douglas fir preservative wood beautiful appearance, texture uniformity, flexibility, etc., can be used as furniture production, the production of various crafts materials, and the production of good

Of the wood preservative will show a better atmosphere.

Third, Douglas fir wood preservative material fine, uniform texture, can be used directly in the wet and harsh environments, the use of time as long as 30 years.

Fourth, Douglas fir wood preservative wood as a member of the coniferous forest, has a rich oil, smooth cross-section, wood and other fine features, can be applied to any different

Of the demand.

Douglas fir Uses:

Douglas fir is known for its excellent strength-to-weight ratio, and its high specific gravity provides good grip and fixing power, making it suitable for making wooden frames for houses, small commercial buildings, multi-storey buildings and industrial buildings.

Douglas fir is not only a high modulus of elasticity, its outermost bending fiber stress, along grain tension, transverse shear, cross grain pressure and grain pressure are also very good.Because Douglas fir with these physical properties, and Heartwood durability and outstanding physical stability, many construction companies around the world have used Douglas fir as the standard for judging ownership of framed timber.

Douglas fir is well known for its structural properties and appearance, and Douglas fir is the most commonly used wood species when designing structures that require large girders, long spans or specially shaped arches (eg, churches, bridges and stadiums). Structural glued laminated beams made of Douglas fir are commonly used as horizontal load bearing frames for roofs, floors and pillars in the construction of houses, commercial buildings, public building structures, tower constructions and water facilities, etc. In the construction of industrial plants, warehouses, And even the need for beautiful appearance of the building structure, the Douglas Fir is also a reliable performance of building materials

Douglas fir dry easily and quickly, crack may be small, good stability specifications. Wood hard, firm, straight lines, good drying effect. Machining is also good, excellent turning characteristics, strong adhesion, nail holding capacity medium. Coloring or painting decorative effect is very good. Douglas fir is widely used structural timber

Douglas fir is widely used in many applications, is favored by engineers and builders, especially for structural parts and heavy wood structure, is also widely used in wood piles, railway sleepers, Sawmills, warehouses, and many other areas where structural performance is important. Douglas fir is a hard and stable wood that can be used to construct light-weight and heavy-duty timber frames.

Douglas fir high strength and good bonding, it is often used to create a variety of structures in the bonding beams, including indoor sports grounds, swimming pools, churches and supermarkets.

Douglas fir is a good-looking, easy-to-handle machine that is suitable for processing window frames and door frames, moldings, cabinets and other joinery products, and Douglas fir's hardness and strength also increases durability.

Douglas fir has high corrosion resistance and excellent structural properties, and therefore is the production of industrial tanks, vats and other storage containers of the main timber. Its stability and ease of processing has also become the choice of manufacturing industrial parts .
