Bar weight 150x150x6000 and its other characteristics

The most common bar in the construction of houses is the material section 150x150x6000 mm. In the process of designing a future building, developers often have a question, how much does such a beam weigh?

Further we will answer this question, and also we will consider on what this indicator depends.

General information

Unlike logs, which have a rounded shape, a bar is a product of square, semi-cylindrical or rectangular cross-section. Depending on the purpose of the material, it may have other forms.

Types of timber

There are several types of them:

• Usual;
• Profiled;
• Glued profiled, etc.

The usual bar is carried out by cutting of a log from four parties. After that, a smooth building material with a square or rectangular section is obtained. As a result, its thickness along the entire length is the same, unlike logs, so it is much more convenient to build walls from it.

Profiled product is obtained by giving the usual beam profile. It necessarily has a groove and spike, which gives it additional positive properties. Glued material is made by gluing several boards, which further improves its characteristics. (See also the article What are the advantages of cedar glued laminated timber)

What determines the weight

The weight of the timber 150x150 mm may vary depending on its type and degree of drying. So the glued product undergoes mandatory drying, respectively, it is easier.

In addition, much depends on the type of wood from which the material is made, as well as its section. It is extremely clear that, other things being equal, the weight of a bar 100x150 mm will be less than that of a material with a cross section of 150x150 mm

What is humidity?

First of all, it is necessary to deal with humidity, since it affects the given indicator most of all. And so, the humidity of a tree is the ratio of the mass of moisture that is contained in a certain volume of wood to the mass of absolutely dry lumber.

Tip! The level of moisture to determine their own hands without special devices will not work, especially for a beginner. To do this, there are special moisture meters - contactless or needle. Preferred first option. This compact device can be useful in the future when purchasing furniture.

Expressed humidity percentage. This indicator of freshly chopped wood is 70–80 percent, “transport” wood has 20 percent moisture, and “dry” wood - 8-12 percent.

I must say that humidity affects not only the weight of lumber, it also depends on the price of the product. In addition, depending on the degree of humidity varies and the intended use of beams.

Lumber moisture

Moisture in the tree is between the cells and in the cavity of the cells. Let's look at how it is dangerous for lumber during construction.

In the process of drying, the evaporation of water is carried out in two stages:

• Evaporation from the extracellular space.
• Evaporation from the cell cavity.

When lumber comes in contact with water after drying, the cells do not absorb moisture, since they are filled with air, and moisture from the intercellular space evaporates by itself, i.e. naturally.

The value of moisture in construction

In production, the workpiece must be dried, not the finished product. If a raw tree was used in the manufacture, then in the process of evaporation of moisture it can be deformed, change the geometric dimensions.

Note! The mass of the product is extremely important in the calculation of structures that create loads on the supporting structures. For example, exact values ​​may be needed when selecting and calculating the foundation.

The weight of lumber is important not only when calculating the load, but also during transportation, since transport companies are not interested in the amount of material, but their volume and weight. In addition, dry products take up less space, respectively, you can immerse more of them. It follows that the price of transportation of dry material is always lower than the “raw” one.

Tip! To prevent the lumber from dampening during storage, it is necessary to use covered areas or cover it with cellophane film.

Weight calculation

The calculation instruction is quite simple.

This is done as follows:

• The weight of one beam is equal to the weight of a sawn timber cube / divided by its quantity.
• To determine the number of pieces in a cube, you need to know its size. For example, you need to know, the weight of the bar is 100x150x6000, first we find the amount of material: 1: 0.100: 0.150: 6 = 11.1 pcs.
• Knowing the mass of the cube, and the number of pieces, it is not difficult to calculate how much the beam weighs 100x150: 860 / 11.1 = 78 kg

Note! Moisture is an ideal environment for the development of rot, fungi and mildew. If the use of non-dried lumber in the construction of buildings and structures, then during operation, problems are guaranteed.

Below is the weight of pine bars of different sections:

• 150x150x6000 mm - 7.4 pieces are placed in one cubic meter, its weight is 860 kg. Weight 1 pc. 150h150 section is 116 kg.
• Mass1 pcs. With a section of 150x100, 78 kg is placed; 11.1 pieces are placed in one cubic meter.
• Weight 1 pc. With a section of 100x100, 52 kg is equal, 16.6 pieces are placed in one cubic meter.

Note! If the weight of a cubic meter of pine beams significantly exceeds 860 kg, then the product is unsuitable for high-quality construction of the house due to the high level of moisture content.

Conclusion

The weight of building material is a very important parameter during construction, without which it is impossible to create the correct design for a future log house or cottage. In addition, weight is an indicator of the quality of the material, i.e. degree of moisture.
