Steel C channels with parallel flanges are often called UPE, Whilst U channels with tapered flanges are generally known as UPN.
I sections which happen to be also called as steel beams or rolled steel joist are thoroughly applied as beams, lintels, columns etcetera. It is composed two flanges in addition to a web connected as revealed in determine.

Alternatively, a smaller steel channel could be extra at The underside in the beam and supported by supports to boost the energy of an present beam throughout a redesign. It may be made use of like a cap in addition to the beam so as to add more power during property development.
These specialized applications are created to meet the precise requirements in the metallic channel being shaped. Roll forming dies are divided into stations, that has a roller for each station that molds the metallic sheet progressively.
The U section nevertheless, ought to have considerably higher radius of gyration, particularly round the x axis, since the majority of the fabric while in the section is situated much from centroid.
Just how a channel is supported or linked at its finishes affects its conduct. Typical end ailments contain simply just supported, cantilevered, and constant.
UPN Channels: The flanges of UPN channels are tapered, indicating they narrow to the top from the flange. This tapering brings about a profile that is definitely a lot more economical in resisting bending and torsional masses for sure apps.
Programs: C channels are commonly Utilized in constructing design, such as frames for flooring and partitions, supports for roofs, and various other structural purposes. Their design permits successful use in mild to medium structural purposes.
The axis is referred to as plastic neutral axis, and for non-symmetric sections, is not the similar With all สินค้าเหล็กรางน้ำ the elastic neutral axis (which all over again may be the centroidal one). The plastic section modulus is provided by the overall components:
Distributor of steel & sheet metal fabrication, processing of merchant bar & structural rolls, cold finished carbon steel bars, steel tube & pipe, plate metal fabrication & steel processing
Much better exterior and inside radius corners and more powerful Net and flanges make aluminum structural channels a more dependable choice for structural apps.
To correctly compute the unit weight of C-channel เหล็กรางน้ำ steel, together with C-purlins, you very first will need to be aware of the basic calculation formulas. The crucial element factors are summarized down below:
For the 2nd scenario, that is certainly once the axis passes from the Net, the plastic modulus is found with equation:
