WELDED BEAM FABRICATION
Welded beam is mainly used to manufacture metal structures.
Welded beams are cost-effective in the construction of buildings and structures.
Welded beams are used in the construction of floor decks, coatings, support pillars, working platforms, scaffold bridges, bridges, crane beams and other steel structures.
Welded beams are especially effective in long span structures of industrial buildings, shops and other facilities.
Welded flange beams are the most common sections, widely used in construction and engineering industry, and T-sections are commonly used in shipbuilding industry.
Welded beams are used as structural metal frames that allow not only to facilitate the construction members possessing unnecessarily large safety factor, but also to create more cost-effective form of supports and cross-sections of individual members, thus reducing the weight of the metal structure.
Welded beam is a welded sheet steel construction with mechanical parameters similar with those of beams made of hot-rolled metal in accordance with GOST 26020-83 hot or STO ASCHM 20-93.
Our company warrants that the calculated mechanical properties of welded beam are as good as those of than the corresponding size of the hot-rolled beam.
The limit deviations in the size and shape of the cross-section are in accordance with STO ASCHM 26020-83 or GOST 20-93.
The welded beam produced by “Poltavaspetsmontazh LLC” is manufactured with wall height (H) from 300 to 1200 mm, wall thickness (s) from 6 to 14 mm and shelves (t) from 8 to 20 mm, a width of the shelves (B) from 150 to 500 mm and a length of 14 m.
The theoretical weight is indicated with the accuracy of +/- 3%. The final weight is determined upon the production
In process of welded beams manufacturing steel flat products are mainly used (steel grade
The manufacturing process of welded beam consists of the following stages:
ADVANTAGES of welded beams
Metal structures including a welded flange beam a welded double-tee beam, provide tangible economic benefits in the construction of various structures and buildings different in their type.
The use of welded flange beams in the composition of framed metallic structures can significantly alleviate the members of these structures with increased safety factor.
In addition, the use of welded beams enables the creation of cost effective forms of supports.
This in turn reduces the metal consumption of buildings and structures.
The perforated wall of the beam is formed by cutting the wall of an I-beam in a zigzag line, followed by a shift of halves and butt welding of the parts of the I-beam on the walls relief.
The bearing capacity of the cross-cutting I-beams exceeds the carrying capacity of the original I-beam, as achieved by their higher altitude.
The main advantage of welded beam is the decrease of cost and timing necessary for INSTALLATION WORKS THROUGH:
TYPES OF WELDED BEAMS
WELDED BEAMS DIMENSIONS
Cross-section of flange welded beam should correspond the cross-section specified in the figure.
Н– beam height; h– height of the beam wall; s– wall thickness; t– plate thickness; В– plate width.
Welded beam dimensions, cross-sectional area, the weight of 1 meter of the beam and geometric values for the axes are shown in Table 1.
Welded flange beam is manufacturing in length from 3 to 14 m in accordance with the order.
