Pre Engineering Metal Building Structure



Conception of Pre Engineered Building Structure:-


  • Tailor made building based on client’s requirement & actual design calculations using tapered sections for straight section.
  • A combination of built up section, hot rolled section, cold formed elements and profiled sheets
  • After Designing, fabrication is done in the controlled environment of factory
  • Building components are brought to site &  fixed/jointed and erected at the site
  •  All connections at site are bolted.


Appropriateness of Pre Engineered Building Structure:-


  • Large Span Buildings
  • Low rise building 25 to 30 m eave height
  • Heavy mezzanine buildings
  • Heavy Industrial Structures
  • Any type of Geographic location
  • Buildings with mix of built up and conventional IS steel sections to suite the requirement
  • Cold hilly area, High rain prone area & Extreme hot climate



Components of Pre Engineered Buildings Structure:-


  • Frames are portal type having slope for drain at roof level.
  • Tapered sections/ Straight section both can be used depending on design are generally used.
  • Webs & flanges with variable thickness are used for individual members.
  • Moment resisting frames provides lateral Stability & transfer load to base.
  • Indian Standard Hot Rolled sections, pipes can also be integrated for economy and suitability.

 Advantages Of PEMB Structure

1. Low initial cost due to:
- the use of tapered built up structural members (Columns & Rafters);
- the use of Z shaped secondary members (Purlins & Girsts) that allows overlapping;
- Foundation are fewer and lighter.


2. Superior Product Quality:
- Design Quality is consistent and is based on latest design in USA Codes.
- Welding is done by professional welders.
- Materials are ordered as per recognized standard.
- Fabrication is done as per a Quality Plan.


3. Fast Project Construction:
- Anchor Bolts are delivered earlier than the Building.
- Buildings are fabricated and delivered within a short period due to standardization.
- Fast erection because all members are field bolted.


4. Functional Versatility: - Modular construction.
- Large clear Spans (up to 100m).
- Long Bay Spacing (up to 13m without Jack Beams).
- Buildings are easily expandable on all sides (allowing for future expansion).


5. Architectural Flexibility:
- Aesthetic features such as fascias, parapets and curved eaves greatly improve the appearance of the building.
- Flashing and Trims are available in different shapes and colors.
- A wide range of wall and roof sheeting.
- Readily available interface details between steel and other materials (glazing, block wall, curtain wall, etc.).


6. Low Maintenance and Operating Costs:
- Virtually no maintenance required for all panels.
- Roof requires only periodic cleaning.
- Annual washing of Eave Gutters.
- Watertight roofs.
- Energy efficient roof and wall systems through usage of insulation.


Evaluation between PEB & Conventional Steel Buildings



Pre-Engineered Buildings (PEBs)

Conventional Steel Buildings


Quick and efficient; since PEBs are mainly formed of standard sections and connections, design time is significantly reduced. Basic designs are used over.

Slow: Each conventional steel structure is designed from scratch by the Consultant, with fewer design aids available to the Engineer.


Average 6 to 8 weeks.

Average 20 to 26 weeks.


Simple design, easy to construct and light weight.

Extensive, heavy foundations required.

Erection Cost & Time

Both costs & time of erection are minimized.

Typically, they are 20% more expensive than PEB. In most of the cases, the erection costs and time are not estimated accurately.

The erection process is easy, fast, step by step and with hardly any requirement for equipments.

Erection is slow and extensive field labor is required. Heavy equipment is often needed.


Outstanding architectural design can be achieved at low cost using standard architectural features and interface details.

Special architectural design and features must be developed for each project, which often require research and thus resulting in much higher costs.

Future Expansion

PEB Building are designed with future expansion in mind. It is simple, easy and cost effective. One supplier can co-ordinate changes.

Future expansion would be more difficult and, more likely, costlier.


Single responsibility for design, supply and even erection of PEBs.

Multiple responsibilities can result in questions of who is responsible when components do not fit properly
