Pre-Engineered Steel Buildings
Pre-Engineered Steel Buildings
The concept of PEB structures has been in the industry for over 40 year which boomed in infrastructure segment drastically due to advantages. One of the reasons in the growing aspect of PEB is its technological and Aesthetical improvement. Multiple products can be used to advance the structures from conventional to multi stored buildings.
Advantages of steel in construction of structures:
- Durability
- Affordability
- Environment Friendly
- Constructability
- Light weight
- Vibration Performance
The design of steel structures plays important role in the complete construction. We follow MBMA-96 / AISC 89-9th Addition – as per ASD, AISI 1986 Edition – 1989Addendum and Euro Code based on the location and requirements.
The understanding pr pre-engineered structures with their design , looks and end usage by client is always important as then there can be optimization done or materials used which is economical for one to build. For basics one should know the option available in market so then the choices can be made. We are here to showcase such options to our client for their economical and solutions for their end products.
1. Clear Span:
There are columns only at the end sections of structure and the entire space is useful for clear movements inside the structures. This is one of the option which can used when ease of movement is required inside the building
2. Centre Columns:
There is one entire line of columns at center of the structure along with end columns. This is more economical compared to clear span. This can be opted when there is not much movement in entire space and this column does not hamper the production capacity. Also, when there are multiple cranes used one can opt this for the crane movements support is provided with the columns.
3. Two intermediate columns:
There are two line of columns in the centre of structure along with the end columns which makes the structure more economical. This can be done when the structure has huge spans.
4. Multi Gable:
There are multiple columns inside the structures based on their span / width.
5. Lean To shed:
This type of structure can be made when the steel shed has to be attached to any other existing structures. This is mainly done while expansions of places are done by client.
6. Single Slope Structures:
General steel structures have slope two side to give some advantages and economical value in the construction. One side slope is opted only if requirement of client is very specific as it not very economical compared to two side slopes.
