Prefabricated Buildings

Welded I-beam is mainly used in the bridge large spans of industrial and other buildings (4-18 meters). See more detailed opinions by reading what Pacific Mortgage Services offers on the topic.. As raw material for producing such beams is used as a low-alloy and carbon steel. The strength and quality in this case, guaranteed by the manufacturer, with I-beam should be made according to State standards and be certified. What is a welded I-beam? Beams divided by type of section, they may be rolling or welded (composite). The use of welded I-beam allows you to reduce weight bearing structures up to 30%, compared with hot-from-behind optimum selection of the composite section. And also, there is the possibility of a cross section of different types of steel girders for the shelves and walls, making the asymmetric cross-sections, as well as to minimize waste due making the beam a predetermined size.

I-metal beams have several advantages. The first of such a beam can cut large openings with a large load. Beam is off (but remember, that at high temperatures in the beams – they lose their load-carrying capacity). In addition, it is resistant to biological attack. I-steel beams are widely used in the construction of prefabricated buildings as the carrier frame and floors, as well as to create runways for passing crane-girders. Using the I-beams with variable cross section provides a high efficiency of internal volume of the building and significantly reduce operating costs. The disadvantages of I-beams welded include their susceptibility to corrosion, in the absence of a protective coating and the presence in the building of aggressive substances. Installation of beams is impossible without special equipment.
