When carrying out a variety of installation work, as well as in the manufacture of furniture items, wood packaging, wooden boards of different sizes are used. This material can be produced from almost any breed. Today we will talk about boards with a size of 30 mm, about their key features and areas of application.
Features and scope
Boards with a thickness of 30 millimeters are currently used in various fields. They have a good strength index. Structures made from these lumber can serve for many years and even decades.
Boards with such a thickness undergo a special treatment during production - drying. Most often, this procedure is performed in special chamber equipment, but some models undergo normal natural drying.
Lumber of this type can be created from various types of wood, but the most common products are pine, spruce, larch, birch, maple and oak. Less commonly, such structures are produced from cedar, aspen and linden.
Boards with such dimensions can be used in various areas of construction. So, they are used when laying floor coverings, both for finishing and rough work. These structures are quite strong and durable.
It is recommended to use tongue-and-groove planks for flooring. They have a tongue-and-groove design that makes them easy to install.
During installation, the spike will easily be inserted into the groove, this fixation technology allows you to form a monolithic coating, and at the same time the risk of cracks will be minimal.
Also, lumber with this thickness can be purchased for the construction of residential buildings, household buildings. Sometimes for these purposes, the most durable glued versions are purchased, which consist of several such boards connected to each other . They are also used in the manufacture of pieces of furniture, stairs, window and doorways.
It is permissible to take boards of 30 millimeters to create country verandas and terraces (it is better to use special terrace materials). Sometimes they are acquired when forming carved decorative products, but models made from more beautiful natural wood species are more suitable for this.
Description of species
Boards with such dimensions can be made in various designs. Let's consider each variety separately.
Trim
These quality lumber is formed by cutting a whole log in the longitudinal direction. Edged boards are necessarily subjected to the deepest processing of all parts at the same time during the manufacturing process ., therefore, they have a maximum service life, a more aesthetic design.
On the surface of such boards there can be no large cracks, irregularities and other defects, therefore they are used for interior and exterior decoration, finishing flooring.
The key difference between edged and unedged sawn timber is that they are produced without wane, their edges are fully processed . According to the official standard, there may be a small wane, but its value is minimal and strictly normalized. The edges of such lumber are at an angle of 90 degrees to each other.
Unedged
An unedged type of lumber is created using sawing logs in the longitudinal direction, like edged views. But at the same time, wane will remain on the edges. Thus, the edges of such boards remain untreated.
The cost of such materials will be much lower compared to the previous option.
Unedged boards are mainly made from conifers. But for this, better quality raw materials are selected with a minimum number of knots and cracks.
These boards should not be used when carrying out finishing work, creating furniture . Most often they are taken for the manufacture of shipping containers, small temporary buildings, as well as for the formation of a rough floor covering.
Planed
Such boards are also subject to obligatory deep processing at the same time on all sides. As a result, you should get products with perfectly smooth surfaces. Planed lumber boasts a high level of resistance to moisture and various temperature conditions . In addition, during processing, they acquire resistance to ultraviolet radiation, deformation, cracking.
These products are environmentally friendly material. They have excellent thermal insulation properties, so they can be used in the construction of reliable residential buildings.
Planed varieties must be chamber dried . They are widely used in finishing works, including in the design of floor coverings, internal partitions in rooms. Their processing is carried out using special equipment.
Dimensions and weight
Boards with a thickness of 30 mm are available in various lengths and widths. The most common models are with dimensions 30x100, 80x30, 90x30, 10 by 30, 30 by 60, 30 by 50.
When erecting residential buildings, boards with dimensions of 30x100x6000, 30x30x6000, 30x30x1000 or 30 by 120 by 6000 are mainly used. The weight of the boards can vary significantly.
This value will depend on many factors, including the width and length, the type of wood, and the type of drying (models that are naturally dried weigh a little more).
Selection Tips
Before buying such lumber, you should consider several significant nuances of choice. Immediately decide for what purpose these boards will be intended. For finishing, creating furniture, preference should be given to planed or edged options . For a rough finish, unedged materials are suitable.
You also need to pay attention to the type of wood from which the boards are made. When building strong structures, including residential ones, it is recommended to purchase models from pine, oak, larch, because this wood is considered the hardest, densest and most durable.
When choosing, remember that dry models are the most preferable option for building reliable structures, strong frames and finishing work. They are stronger and more durable than natural moisture boards.
Be sure to look at the type of wood from which the boards are made:
- Grade 1 - used in the construction of door, window openings, stairs, finishing;
- Grade 2 - used to create formwork and lathing, the construction of a strong flooring, a building structure of the bearing type;
- Grade 3 - purchased for the creation of load-bearing structures of the third category, cargo containers;
- 4th grade - also used when creating containers and small blanks.
When choosing lumber, experts advise paying attention to the dimensions, the strength of the material for bending and compression, the compliance of the boards with permissible moisture indicators.
