Wooden beam (doka)

Wooden beam (doka) for Formwork in Yerevan.

The timber Wooden beam (doka), also known as the H20 beam, is a multifunctional construction element used for various purposes, including wall and floor finishing, roofing, and support structures. However, its key role is revealed in monolithic construction, where it serves as an essential part of slab formwork. The beam creates a grid for the deck by being installed crosswise. This design effectively distributes the load of the poured concrete, prevents plywood deflection, and ensures the high quality of the monolithic structure. As a result, it reduces finishing costs and overall construction expenses.

Construction 

Wooden beam (doka) is a strong, lightweight, and durable element that provides even load distribution and stability of the entire formwork structure during concreting.

The construction of the H20 (Doka) beam is an I-shaped profile consisting of a web made of moisture-resistant plywood and flanges made of high-quality coniferous wood. The flanges are usually made from solid timber bars treated with protective compounds, while the web is manufactured from laminated plywood approximately 27 mm thick, resistant to moisture and mechanical stress. The elements are bonded with industrial-grade adhesive, ensuring strong adhesion and preventing delamination.

Features

Standard specifications:

• Length: from 2.0 to 4.5 m (5.9 m and 6.0 m also available)
• Profile height: 200 mm (H20 standard)
• Flange thickness: ~40 mm
• Web thickness: 27 mm
• Weight: approximately 4.5–5.0 kg/m

The low weight is one of the most important advantages, as it speeds up installation and reduces the physical load on workers, eliminating the need for heavy machinery during assembly. Despite being lightweight, the beam has high load-bearing capacity — it can withstand significant vertical loads and does not deform when used properly.

Another key feature is its resistance to moisture and mechanical impacts, thanks to protective coatings, laminated end surfaces, and moisture-resistant plywood. With proper use, the beam can serve 50–80 concreting cycles or more.

Industrial moisture-resistant adhesive ensures a long-lasting and reliable bond of all wooden elements throughout their entire service life.

Applications

Timber wooden beams (doka)are widely used by professional construction companies due to their high reliability and reusability.

• Slab formwork (as main and secondary beams)
• Wall and column formwork
• Construction of monolithic residential, commercial, and industrial buildings
• Temporary or combined load-bearing structures

H20 Doka-type beams work perfectly with telescopic stand for formwork, tripods, fork heads, and laminated plywood, creating a strong and universal formwork system. Thanks to their standard size and high compatibility, they are suitable for large construction projects as well as private home building.
