All About Steel Frame Structure And Steel Fabrication
Most of the steel fabrication involves a steel type called mild steel. Mild steel is an extremely strong form of steel and its immense strength is what makes it advantageous for buildings. Another great benefit steel frame structures is their flexibility. They can be bent without cracking and thus do not break when pushed sideways by let’s say an earthquake or wind.
It is because steel frames have the ability of creating large spaces and involve low cost
It is because steel frames are immensely strong and have a low weight. Also, their construction does not take much time.
It is because of the same reasons mentioned under industrial buildings i.e. low cost and ability to create large spaces.
As steel frames can be quickly constructed and removed.
Steel frames are fitted in residential buildings using a technique called “light gauge steel construction”.
Conventional Steel Fabrication
This construction method involves cutting of steel to correct lengths and then welding the pieces together to make the final structure. This can be done at a labor-intensive construction site or partially at a workshop to reduce construction time.
Bolted Steel Construction
This type of construction occurs when the steel constructors manufacture finished, painted steel parts, which are afterwards transported to the construction site where they are bolted together. This steel construction method is preferred over other methods as most of the construction is done at the workshops which saves time.
Another advantage of this method is that as the workshops have all the required machinery and better working conditions as compared to construction sites, the fabricators find it easier to work in workshops.
One of the most common example of bolted steel construction are pre-engineered buildings as they are first designed, then fabricated in workshops, and finally transported to the construction sites where they are erected.
Light Gauge Steel Construction
This type of construction process is common for residential buildings and other small buildings. It is quite similar to wood-framed construction. The only major difference between the two methods is that light gauge steel construction uses light gauge steel parts in place of wood.
Light gauge steel is in form of thin sheets of steel that are bent to form C-sections and Z-sections. However, if you use this type of steel, make sure they are tightly bolted, else they may fail to resist wind forces and blow away like umbrellas.
They are time-efficient as most of the work can be done at the factory.
They are flexible and do not break suddenly like glass which makes them highly resistant to wind forces or earthquake etc.
They can be bent into any shape and can be cladded with any other material.
They can be joined by various methods like welding, bolting, and riveting.
They may lose strength when exposed to high temperatures or fire.
They can corrode in humid or damp environments.
