H20 beams

Doubl-T-iron (I-beam) is a modern building material. It has several advantages over the other elements of the overlapping
installations made by reinforced concrete.

Doubl-T-iron (I-beam). I-beams made of solid wood with shelves, where there are the grooves, and rack of plywood or carpentry
plate located in these grooves. I-beams are very relevant for the prevention of overlapping deformation. At observance of correct
operating conditions of a good I-beam provides high quality and sustainability of structures.

I-beam of solid wood has a number of advantages:

• The durability. The beam is glued in several layers and it is covered by waterproof composition
• Quick and easy installation due to a small proportion of the beam, absence of necessity of special technique for lifting and installation.
• Completely adapted to any weather conditions due to a special moisture-proof applied to the beam structure.
• I-beam helps to reduce the construction period and significantly reduce the weight of the object that allows avoiding the shrinkage.
