What is the difference between a bar and a bar?

You can find a lot of lumber in today's construction market. And if everyone knows what, for example, a board is, then not everyone can distinguish a bar from a bar. It is about the difference between these two concepts that will be discussed in this article.

If we consider the words "bar" and "bar" from the point of view of philology, it becomes clear that a word where there is a suffix "ok" with a diminutive form means something less than the base of the same root word. That is, the bar should be smaller in size than the bar.

Indeed, there is a visual difference in size. GOST standards give us the following concept of a timber: this is lumber, the thickness and width of which is at least 10 centimeters (100 mm). If any of these parameters are less, then we are no longer dealing with a bar.

As for the bar, it also has dimensions: in thickness it goes less than 100 millimeters, but the ratio of width and thickness should be strictly 2: 1. If this proportion is violated, then it is most likely already a board. As you can see, it is easy to make a bar from a bar, and a board from a bar.

Due to the difference in thickness, the described sawn timber is used in various construction situations. The timber is a more massive and durable material. It is mainly used for supporting structures: beams, supports are erected. Sometimes it is used for walls.

The bar is not particularly durable, and therefore it is used for the construction of auxiliary structural elements. So, if you need to make a plank flooring, then use bars. They are necessary for roofing work, they are also used as logs and in other cases. Bars are widely used in the manufacture of furniture and packaging.

Both timber and bar are wooden building materials that are necessary for the construction of wooden cottages, as well as in the manufacture of structural elements made of wood (window and door elements, stairs, etc.).

The bar differs from the bar in the production technology. A bar is obtained as a result of sawing a board or a bar, and therefore it is only wooden. Depending on how the processing was carried out, the bars are planed or calibrated.

If the timber is obtained from wood (hewn log), then it will also be planed or calibrated. The timber can also be glued from boards. But the main difference is that the timber can also be made of metal and stone. The standard construction beam is 200 mm wide and 200 mm long.

Both materials are made of wood, and therefore they are classified as environmentally friendly building products. True, the timber glued from the boards, the so-called lamella, has an element of chemical composition - a special glue. Glued laminated timber is assembled from individual wood fragments: this technology was invented in the West, where there is an obvious shortage of natural resources. It was there that they began to make such a bar. Outwardly, it cannot be distinguished from an integral massif, but it is inferior in terms of environmental indicators.

However, in Russia, glued laminated timber is not popular: it is a more expensive and non-ecological material that has not passed the test of time in the harsh Russian climate. In addition, we do not have a deficit in forest resources, therefore, both timber and timber are made from an ecological material - wood.

The timber is subjected to chamber drying or there is natural moisture. When working with it, it is important to understand what kind of material you are dealing with: wet or dry. It will depend on this whether the building will shrink or not. In the first case (with natural humidity), structures are erected taking into account the shrinkage of the house. If the timber dries naturally: in a finished log house or in stacks, then the building will certainly shrink. But if the material has passed forced drying (in a special thermal chamber) even before use, then the construction is erected on a turnkey basis. In this case, you should not expect shrinkage at home.

You also need to know that the calibrated timber and the bars are already dried, that is, they are pre-processed according to the specified parameters, so that later, when using the materials, it does not "lead" from moisture evaporation. It is enough to process the walls erected from such material with a special compound from the outside, and then you will not have to think about additional external finishing.

It is no coincidence that our ancestors built wooden log cabins for themselves. The fact is that wood belongs to materials with low thermal conductivity, that is, wood is able to keep heat for a long time. Houses based on wooden beams are considered more solid. They are used for building both summer buildings and houses for living in winter.

Here we must proceed from a simple and understandable rule: the thicker the timber, the thicker the walls will be, which means that in winter the house will cool more slowly. It is customary to build summer buildings from timber up to 150 millimeters thick, while winter structures come with materials over 150 mm.

Ideally, for a winter log house, it is better to take lumber (timber) with a thickness of 200 millimeters. It is no coincidence that the classic size of a building beam is 200x200 mm.

If there is a need for finishing, then a bar is mainly used. This versatile material is also used in the construction and design of gazebos, decoration of terraces, stitching of roofs, for the construction of various flooring and in other cases requiring a base or auxiliary elements made of wood.

The timber mainly serves as a building support, but if the walls are erected from dried material, then the external decoration can be limited only by special processing of wood. Sometimes a board "imitation of a bar" is used. She sheathed walls both outside and inside, floors, pediments.

Bars are indispensable in the construction business and are a versatile material. The reliability of the auxiliary structures of the building directly depends on the quality of the bar. For the construction and finishing work itself, it is better to take selected planed products, but in general, both first-class and second-class elements are suitable.

For external work, preference is given to coniferous wood. When forming the roof for the lathing, you can use edged columns. Always consider what kind of wood you are dealing with: dried or with natural moisture. When forming battens (especially on the roof), it is better to use only dry wood, because shrinkage can lead to disastrous results, up to the destruction of the structure. Or choose products that have passed chamber drying or with a humidity level not exceeding 20%.

Sometimes small trims are needed to reinforce corner joints. It is noteworthy that the bars as supports cannot be used in gazebos, but in greenhouses this is permissible. This is due to the fact that in gazebos, a large load falls on the supports due to the fact that the roof has significant weight.But during the construction of greenhouses, there are much more supports, and all of them evenly take on the total load, so you can take a beam (10x10 cm) for the base, and use bars (5x5 cm) as structural supports to create a frame.

The timber can also be of different types: for a simple edged material, all sides are even, and the profiled one comes with grooves and protrusions. The first is used for finishing work, laying floors and in other cases where a smooth surface is needed. A simple timber is inexpensive, it goes to roof beams, vertical supports in the house, and also as a strapping element in a pile foundation. And the profiled beam is used to dock with each other similar elements in a row when erecting a log house.
