A steel beam is a product that is meant to take the weight and pressure of heavy loads. It can be curved, tapered or straight. The importance of a steel beam lies in its essential duty- to carry the weight of the construction. The building can be of any kind. A residential complex, a house, a commercial space, a giant airport, railway lines- every kind of construction. Steel beams have fast replaced concrete in building work. Concrete is difficult to work with, it is often brittle and goes through wear and tear in the lifetime of a building. Steel, on the other hand can be manufactured to any exacting standard, in quantities large and small, and generally requires virtually nil maintenance. This makes steel beams a wise and economical choice.
Here are some kinds of steel beams London:
W or H beams- wider than the I beam, the flanges in these are untapered and long. These are widely used in residential constructions. The flange and web has equally thickness in quite many cases.
I-beam- the beam looks like it sounds- it is shaped like an I. it is the most common beam you’ll see. It has tapered sections and come is two kinds. One if the S-beam, where there is a slope on the inner flange. The other is the wide I beam, where there is a parallel flange. This is also known as the rolled steel joist or the RSJ and universal beams. These beams are much higher than broader. When a universal beam is measured, the consideration is always height, width and then weight.
T-beam- this beam has a cross section shaped like a T.
C-beams- these are channels and have a c shaped cross section. They are not as strong as the other beams and should be used only for light weights. These are also called parallel flange channels.
Because the beams offer support, they are classified according to this function too.
Cantilever-this beam projects outwards and is fixed on one end.
Supported- because they are supported at the ends, they can rotate freely.
Trussed-this is a reinforced steel beam; its added strength comes from a cable or a rod.
Continuous- this beam offers support to two or more walls and columns.
Over-hanging-like the name suggests, these beams offer extra support on one side. When it’s both sides, it’s called the double-over hanging beam.
Fixed- this beam offers support, but unlike the supported beam, it cannot rotate.
304/L is the go-to choice for environments that are corrosive. If you need something that’s highly resistant to acid and to corrosion, then a 316/L might be a much better choice. There’s less chance of your beach bungalow developing rust! It is possible that you may need something even stronger than these choices. In which case, super austenitic, and duplex stainless steel are possible choices to consider.
Steel has a high shelf-life, can save on landfill bills by being environmentally friendly, requires very little maintenance and can be moulded into any shape desired. As a decorative element or as a practical requirement, steel beams lend themselves to all spaces.
