The I-beam is used in frame housing construction. The use of wooden I-beams in ceilings in frame housing construction allows:
reduce the cost of building foundations;
speed up construction time;
significantly reduce the overall weight of the building.
Compared to the use of simple beams in construction, the use of I-beams avoids problems such as shrinkage, shrinkage, shearing, cracking, creaking of the finished structure, and more.
