Universal Columns Otherwise known as Lintels, Girders, RSJ, RSJ beam, Rolled Steel sections, H Beams, H irons, W beams, steel column and UC's. Universal columns are essential for any major support or structural integrity in building construction.
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an I or H-shaped cross-section. The horizontal elements of the I are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering.
The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.
S355JO
S355JO is a medium tensile, low carbon manganese steel which is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition. Machinability of this material is similar to that of mild steel.

What is difference between UB and UC?
UC – universal column or UB – universal beam.
Universal columns are the most often used sections for structural steel purposes. Unlike a universal beam, the UC's width is roughly equal to their depth. For example, a 152 UC 23 is 152 mm wide and 152 mm deep and 152*89 UB 16 is 89mm wide and 152mm deep.
What is the difference between S275 and S355 steel?
S275 provides a lower strength (than S355) but has good machinability and can be welded. The average minimum yield for S275 steel is 275 N/mm² giving its name: S275.
