Bar 40 to 40 - a multifunctional building material

It is hard to imagine a building site, wherever lumber of different formats is used in one capacity or another. Even if the basic structures are built of stone and concrete, you still have to resort to using wooden products.

Wood is the most environmentally safe material, not inferior in its physical and technical properties, and often the leading one among its construction counterparts.

Wooden rail - timber

Wooden beam is made in different sizes from the smallest sections of 20x20 and to the huge, non-standard - timber 400x400 mm, this also applies to the length of the products. 2, 3, 6 meters are considered as standard, but under the order you can make a bar of any individual size.

Of course, the beam 400 to 400 is used quite rarely. From large format sawn timber, timber 200x200 is more often used for the construction of wooden houses and cottages from a bar. More bulky products and cost more and time consuming when laying.

However, the primacy of participation in construction sites and not only, for a long time and for a long time captured a wooden bar 40x40.

The range of application of this lumber is extensive:

• The device bases for the frame-sheathed structures of walls, partitions.
• The device frame for finishing work, followed by plating:

• Plasterboard plates.
• Wood chipboards (DSP, OSV).
• Fiberboard sheets.
• Plastic panels or clapboard.
• Board, clapboard from wood of different breeds.
• MDF panels.

• Furniture manufacturing.

Classification

This section contains everything you need to know about this lumber, for everyone who wants to build, repair or decorate their own house, cottage, apartment with their own hands.

Bars 40 by 40, like other wood products, can be divided into types, according to:

• Manufacturing technology.

• Planed.
• Нестроганый.

For the installation of frames for lining or erection of walls and partitions, filing ceilings or device lag, as well as crates on the beams of the roof, you can use a non-planed timber. It is not necessary to invest extra money in materials involved in hidden works.

For the same purpose, coniferous timber is used for the above processes. Lumber from pine and spruce price, we can say the budget, compared with a bar of oak, larch.

Note! Before you acquire the material, decide on its purpose, from this it will be possible to make a start when choosing one or another breed.

The latter are more often used as raw materials for production:

• Window blocks.
• Door boxes, canvases.
• Facing surfaces from inside and outside buildings.

The 40x40 bar found its niche in the production of furniture.

Here lumber is used in two ways:

• Production of frameworks of cabinet and upholstered furniture.
• As the main material for the creation of ensembles of kitchens, landscape gardening sets, office and other furniture.

The cost of species of timber

The price of timber varies according to the classification. In addition, the final purchase price may significantly affect the volume of the purchase. Usually, the calculations for timber are carried out with the expectation of a cubic meter, but just in the case of a 40x40 timber, very often people talk about things.

For recalculation into pieces from cubic meters you will not need complicated instructions.

If necessary, you can do it in two stages:

• Calculate the volume of 40x40 timber of your chosen length by multiplying all the parameters in a single system of units. For example: for a timber 40x40x2500 mm -0.04х0.04х2.5 = 0.004 m3.
• Divide one cubic meter by the volume of your timber and get the number of pieces - 1 / 0.004 = 250 pcs.

We present the averaged information about the cost of timber 40x40 in the Russian market in terms of unit of product (units), in ascending order:

• Conifers (spruce, pine).

• Nonstrict timber.

• Length 2m.p. -25 rubles
• 3 mp - 40-60 rubles
• 6 pm - 80 rubles

Attention! When purchasing a timber, be sure to check the conformity of the declared grade and linear dimensions of the products. Tuk should also pay attention to the geometry of the timber along the entire length and the moisture index.

Timber weight

In the absence of a moisture meter, the degree of dampness of the wood can be checked for weight. One cube of dry pine or spruce lumber weighs approximately 450-470 kg, material with a natural moisture content of 800 to 900 kg.

In terms of timber unit 40x40x2500 mm:

• Dry - (450/1) / (0.04х0.04х2.5) = 1.8 kg.
• The natural moisture content is (800/1) / (0.04х0.04х2.5) = 3.2 kg.

It is easy to understand, having estimated "by eye" in appearance. The dry product is lighter, it can get tangled, the wet rail will be darker due to the water that is between the fibers of the material.

Conclusion

As you can see, the low cost of sawn timber has done its job, small-sized wooden lath is in demand in any area. Such a timber is convenient not only during installation, because it is light, but also during transportation, because it is small.
