In modern construction, rolled metal of a wide variety of assortments is in no less demand than classical materials (reinforced concrete slabs or bricks). At the same time, a special place in the list of used types is occupied by metal (steel) I-beam - a beam, in cross-section having the shape of the letter "H" ... Product of this form:
- Almost 30 times harder.
- More than 10 times stronger.
A square or rectangular profile with the same cross-sectional area (respectively, with metal costs). These parameters served as the basis for the use of this type of rolled metal as a load-bearing element of structures:
- Roofs or floors.
- Foundations of supports or columns.
The I-beam is also widely used in the engineering industry - elements of frames for heavy equipment, railway cars and guides for moving lifting mechanisms (beam crane, telphers).
Manufacturing methods
I-beams are manufactured at metallurgical enterprises using low-alloy or carbon steel grades. The final products also differ in the manufacturing method:
- Hot rolled - a given shape and stretching along the length is carried out when processing a workpiece heated to a certain temperature.
- Cold Rolled Crimp - The equipment includes special nip rolls through which the workpiece is pulled.
Another option that is used in the manufacture of an I-beam at small enterprises is welding of metal strips cut from sheet metal. These products have low strength rates and are used in non-critical areas.
You can choose an I-beam with the required dimensional and strength parameters using the official website of the supplier of this type of rolled metal from the manufacturer's factories. The products presented in the catalog fully comply with the standards of the current GOST.
