1. Types of steel building construction
There are several types of steel building construction. Steel construction is also called
steel fabrication.
* Conventional Steel Fabrication is when teams of steel fabricators cut members of steel to
the correct lengths, and then weld them together to make the final structure. This can be done
entirely at the construction site, which is labour-intensive, or partially in a workshop, to provide
better working conditions and reduce time.
* Bolted Steel Construction occurs when steel fabricators produce finished and painted
steel components, which are then shipped to the site and simply bolted in place. This is the
preferred method of steel construction, as the bulk of the fabrication can be done in workshops,
with the right machinery, lighting, and work conditions. The size of the components are governed
by the size of container they are shipped in, usually with a max length of 12m (40ft) for container.
Since the only work to be done at site is lifting the steel members into place (with cranes) and
bolting, the work at site is tremendously fast.
*Pre- Engineered buildings are an example of bolted steel construction that is designed,
fabricated, shipped and erected by one company to the owner.
2. Products scope of using:
Steel is the most preferred metal for the construction of large structures such as bridges, single
storey and multi-storeys industrial buildings, and residential buildings. Steel construction is most
often used in :
* High rise buildings because of its strength, low weight, and speed of construction
* Industrial buildings because of its ability to create large span spaces at low cost
* Warehouse buildings for the same reason
* Residential buildings in a technique called light gauge steel construction
* Temporary Structures as these are quick to set up and remove
3. Advantages of steel structures
Steel structures have the following advantages:
* They are super-quick to build at site, as a lot of work can be pre-fabbed at the factory.
* They are flexible, which makes them very good at resisting dynamic (changing) forces such as wind or earthquake forces.
* A wide range of ready-made structural sections are available, such as I , H, U and angle
sections
* They can be made to take any kind of shape, and clad with any type of material
* A wide range of joining methods is available, such as bolting, welding, and riveting

7. Erection in site
* Each piece of the system is very much alike - an H section with end plates for bolting. The
painted steel sections are lifted into place by crane, and then bolted together by construction
workers who have climbed to the appropriate position. In large buildings, construction can start
with two cranes working inwards from both ends; as they come together, one crane is removed
and the other finishes the job. Usually, each connection calls for six to twenty bolts to be installed.
Bolts are to be tightened to exactly the right amount of torque using a torque wrench.
