1. Structural characteristics of Douglas fir

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

Douglas fir is the most commonly used wood species when it is necessary to design large-scale wooden beams, long-span or special-shaped arches (eg, churches, bridges, stadiums, etc.) for structural design and appearance

Structural glued laminated beams made of Douglas fir are commonly used as horizontal load-bearing frames for roofs, floors and columns in the construction of houses, commercial buildings, public building structures, tower buildings and water facilities

In the construction of industrial plants, warehouses, garages, and even the need for beautiful appearance of the building structure, the bonding beam is also a reliable performance of building materials

2, appearance level Douglas fir wood characteristics

Douglas fir has a light rose color and beautiful straight texture, the color of the sun after drying dark Douglas fir tough fiber is not easy to hand cutting or carving, but as long as the use of sharp electric tools and machine tools can be obtained smooth cutting surface

This wood can be processed into a variety of products along the grain shape, the surface easy to paint, and can maintain a variety of stain and varnish.

3, Douglas fir surface treatment

Douglas Fir can accept various types of dyeing treatment, the surface treatment materials including transparent paint, transparent paint, varnish, paint or wax, and even a variety of colors and bright or soft color paint

In order to obtain the best surface treatment effect, the moisture content of wood should be between 12% and 15%, or as close as possible to the normal humidity.Outdoor construction should be coated with a primer, because Douglas fir is a comparison Dense heavy wood

Preservative wood Introduction:

Antiseptic wood is planed into the pressure tank after the vacuum and then into the preservative for preservative treatment, followed by drying or natural drying.

Antiseptic wood technology originated in Europe, but the production technology does have developed in Japan, and the use of large wood preservative indeed China, as the rare few wood preservative professional production and research and development enterprises,

Suqu wood is committed to research and development and breakthrough.We and can produce the European standard level of preservative wood products, but this is far from enough, our goal is to go beyond the Japanese wood preservative industry, a new generation of the new century wood preservative industry giants .
