Beams CLT

Cross laminated timber beams are a modern alternative to structural concrete. The material is lightweight and can be used to create complex structures without adding weight. CLT is engineered wood made by gluing lumber in layers, is highly durable and flexible and will become an indispensable assistant in the implementation of a variety of architectural and design projects.

Thanks to special production technology, timber serves for many years, retaining its quality characteristics. Glued laminated timber is easy to install, and has a low cost, which allows you to complete construction faster and save money.

Manufacturing Process of CLT Beam

Cross Laminated Timber timber consists of 3-9 layers of lamellas. Blanks are made from pine wood. Each layer consists of blanks laid crosswise and glued together, having a symmetrical structure. The material production process consists of the following steps:

• choice of lumber;
• sorting of raw materials;
• the planning of blanks;
• application of glue;
• pressing from four sides;
• the cutting array on CNC machines.

The lamellas of the CLT beams are joined with formaldehyde- and solvent-free polyurethane adhesive. Only high-quality glue is used, intended for the manufacture of load-bearing wooden structures.

Areas of application for the CLT beam

The timber can be formed into a variety of structural components, including precast, parallel, and span clt laminated timber beams. Load-bearing, non-bearing, diagonal wall elements, as well as roofing and ceiling structures, are made from cruciform KLT material. They can be created by taking into account individual requirements for fire protection, heat, and sound insulation. Therefore, the material is well suited for the construction of private and multi-family residential buildings, commercial and office buildings, and public buildings, such as schools, kindergartens, and hospitals.

Benefits of the CLT Beam

CLT beams offer many advantages over concrete structures and solid wood elements. Here are the main ones:

• Rapid construction and finishing. The elements do not need to be stored at the construction site, they are manufactured in the required dimensions and delivered to the construction site. Both the finished surface and the supporting structure are made from beams, so it takes very little time to finish.
• Good fire resistance. In the event of a fire, the panel is charred, but its load-bearing capacity is fully preserved.
• Large selection of styles and sizes. Beams can be used for load-bearing and visual structures. They are made in different styles and sizes, which allows you to quickly and efficiently implement any project.
• Environmental friendliness and safety. The building material is made from natural wood. In production, even second-rate raw materials are used, which is an effective use of natural materials. In addition, the carbon footprint of laminated veneer lumber is significantly lower than that of other building materials. Glulam beams contain no elements harmful to health, the adhesives used do not contain hazardous substances.
• Good heat and sound insulation. Excellent thermal conductivity ensures a pleasant indoor temperature at any time of the year, while good sound insulation parameters protect from outside sounds and privacy.
• High bearing capacity. The method of production by gluing crossed lamellas ensures dimensional accuracy and structural strength.
• Excellent static properties.
• Lightweight. Thanks to this advantage, the building material can be used for the superstructure of the upper floors without unnecessary load on the foundation. Due to the transfer of load in two directions, any architectural forms can be created from the beams.

Cross laminated beams are produced under European quality standards, and the manufacturing process of the material is fully certified.

Dimensions and Specifications

Wooden elements are cut on modern CNC machines, the details are dimensionally stable and statistically strong. Standard parts have a thickness of 63-295 millimeters in formats up to 3×15 meters. The building material has the following specifications:

The material has a high specific strength, is resistant to salt aggression, and aggressive chemical environments, and has good moisture-resistant characteristics. The coefficient of linear expansion across and along the fibers of solid wood is almost ten times less than that of a metal. In this regard, during the construction of buildings from timber, expansion joints are not made.
