Types of Structural Steel in Nepal

Hello readers, hope you are doing well. Today the use of structural in Nepal is rapidly increasing. Structural steel is being famous in Nepal and globally. Structural steel is used for making steel structures and construction of buildings in Nepal. Here, in this article, you will get to know everythig about the types of structural steel in Nepal.

Structural steel in Nepal

Structural steel is used for making steel structures. The steel structures are very famous because they are affordable. Moreover, they are durable and take less time for construction. We can see different steel structures in Nepal. One contains 70% or more of the structural steel for construction. And in some other construction steel structures are used only as the internal component.

Structural steel provides support to the building. Buildings made from the use of structural steel can withstand harsh weather. They can bear an impressive load too. Structural steels are the category of steels in a variety of shapes that are used for construction. Many structural steel shapes take the form of an elongated beam with a profile of a specific cross-section.

Different Types of Structural Steel in Nepal

I-Beam

The I-beam is one of the widely used structural steel. It is also called the H-beam, wide beam, W-beam, universal beam (UB), and rolled steel joist. I beams are popular for structural steel buildings because of their high functionality.

Their shape makes them excellent for unidirectional bending parallel to the web. The horizontal flanges of the I-beam resist the bending movement, while the web resists the shear stress. I-beams can take various types of loads and shear stresses without buckling. Moreover, it also helps in fabrication.

Z-Shape

One of the popular structural Steel is the Z shape structural steel. These Z shape structural steel are cold-formed and used as structural members for modular steel-framed buildings.

These structural steels are used for constructing curtain and partition walls, as well as for ceiling joists, eaves beams, frame beams, and roof purlins.

HSS-Shape (Hollow Structural Sections)

HSS Channel is also known as Hollow Structural Section steel. It is a high-strength welded steel tubing used for columns and aesthetic purposes, particularly in exposed structures.

Angle (L-shaped cross-section)

L-shaped structural steels take an L shape, with two legs that come together at a 90-degree angle. L angles are typically used in floor systems because of the reduced structural depth.

Structural Channel / C-Beam / C Cross-section

Structural C channels have a C-shaped cross-section. C Channels have top and bottom flanges, with a web connecting them.

These C-shaped structural steel are cost-effective solutions for short- to medium-span structures. C Channel structural steels were designed for bridges. However, they are popular for use in marine piers and other building applications.

Tee (T-shaped Cross-section)

A T beam is a load-bearing beam with a T-shaped cross-section. The top cross-section is the flange, with the vertical web below. A structural Tee is used as a span to support steel decking and concrete floor slabs.

Moreover, Tees can also be used to reinforce concrete T-shaped beams and special “bar size” tees can be used to reinforce concrete bars.

Open Web Steel Joist

The open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points.

Round Shape Structural Steels

Rounds structural steel is a hot rolled, mild steel solid steel bar that is ideal for all general fabrication, manufacturing, and repairs.

These structural steels are used for anchor bolts, pins, rollers, forging industries, auto-ancillaries, bright bar industries, foundation, bushes, and much more steel structure works.

Flat Structural Steels

Flat structural steels are thin strips of mild steel with the thickness of the strip varying commonly from 12mm to 100mm. These flat bars are flimsy portions of mild steel with the fluctuated thickness of the strip that are abounded in low temperature which grants higher solidarity to the structure. MS flats are viewed as the most fundamental of steel structures.

Flat structural steels are uses to , link plate, brilliant bar ventures, car and auto-ancillaries, truck trailers, tippers, railways, transport body, lifts and elevators, scaffolding makers, base plates, earthing material, shipbuilding, washers, spines, clips and a lot all the more designing enterprises.

Advantages of Structural Steels

High earthquake resistance and less probability of damage in an earthquake. A lighter structure with stronger connection results in less seismic force.
The use of structural steel makes construction work fast.
Rust free as the structure is galvanized.
Nor vulnerable to any type of fungi or organism.
The Less probability of foundation problems – as the structure is light.
Less probability of damage in high winds because of the strong fastening technique.
Lighter than other framing materials. No lifting equipment is required on site.
Easy material selection.
Less scrap and waste – less than 2% waste.
Using it to develop frameworks of a building or the entire structure could help the builder save a lot of money.
The use of structural steel makes space for a lot of creativity and aesthetically pleasing designs.
The high strength of steel results in safer structures, less maintenance, and slower aging of the structure.

Disadvantages of Structural Steels

We know Steel is an alloy of iron. This makes it susceptible to corrosion and rust. Therefore, it affects the durability of buildings made from structural steel.
Extensive fireproofing costs are involved, as steel is not fireproof. Thus, In high temperatures, steel can lose its properties and will be weak.
There is a chance of buckling with structural steel. Therefore, If the length of the steel column increases the chances of buckling also increase.
