Google+ What are PEB Prefabricated Buildings Fabricated Metal Buildings | Fast Construction

F A C T S

Cut  Cost by 50%  for PEB having larger clear spans whereas such clear span structure is impossible in concrete structure.
PEBs have high architectural flexibility allowing easy modification and expansions  in the future .
PEBs are made of steel, a homogenous material , works equally well in stress reversal  conditions in tension or compression
A PEB requires less than half of the time needed to construct a concrete building of same size...  
Steel is fully recyclable material whereas concrete is still being looked for recycling.
PEB frames can be easily dismantled and transferred to another location with low additional expense.
Customers can save 50% time in the PEB project construction compared to a concrete building..
PEBs erection costs low & requires less manpower & construction equipment compared to concrete buildings.  
PEB's construction errors can be easily modified on site even after erection unlike concrete structures.

BASIC BUILDING PARAMETER & TERMS

Basic parameters of Pre-Engineered Building

Building Width is defined as the distance from outside of eave strut of one sidewall to outside of eave strut of the opposite sidewall. This does not include the width of Lean-To buildings or roof extension:

Building Length is longitudinal length of the building measured from out to out of end wall steel lines.

Building Height is the eave height which is the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from finished floor, eave height is the distance from finished floor level to top of eave strut.

Roof Slope (x/10)  is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/10 and 1/10. However any practical roof slope is possible.

End bay length  is distance from outside of the outer flange of endwall columns to center line of the first interior frame column.

Interior bay length is distance between the center lines of two adjacent interior main frame columns. The most common bay lengths are 6 m, 7.5 m and 9 m.

Design Loads unless otherwise specified  PEBs are  designed for the following minimum loads:
## Roof Live Load: 0.57 kN/m2
## Design Wind Speed: 110 km/h

Design for snow loads, earth quake loads, collateral loads, crane loads or any other loading condition, if required must be specified at the time of request for quotation.

PRIMARY FRAMING

Fast Construction pre-engineered buildings are tailor made to meet your  requirements. The most common Primary Framing systems are shown below. However any frame geometry is possible.

    • Minimum yield strength is 34.5 kN/ cm2

We can produce other non- standard main frames, of almost any configuration, if required.

SECONDARY FRAMING

Purlins, girts and eave struts are secondary structural members used to support the wall and roof panels. Purlins are used on the roof; girts are used on the walls and eave struts are used at the intersection of the sidewall and the roof.

Secondary members have two other functions:

    • Acts as struts that help in resisting part of the longitudinal loads that are applied on the building such as wind and earthquake loads
    • Provide lateral bracing to the compression flanges of the main frame members thereby increasing frame capacity.

Purlins, girts and eave struts are available in high grade steel conforming to ASTM A 607 Grade 50 or equivalent, available in 1.5 mm, 1.75 mm. 2.0 mm, 2.25 mm, 2.5 mm and 3.0 mm thickness. They come with a pre-galvanized finish, or factory painted with a minimum of 35 microns (DFT) of corrosion protection primer.

    • Minimum yield strength is 34.5 kN / cm2

APPLICATIONS OF PRE ENGINEERED FABRICATED BUILDINGS

Almost two thirds of single  storey  commercial/industrial construction, in the USA, are pre-engineered buildings. The applications of pre-engineered buildings range from small car parking sheds to 90 m (+) wide clear span aircraft hangars to sprawling ware houses. Almost every conceivable building use has been achieved using the pre-engineered building approach.

 Pre Engineered Buildings are primarily being used in:

Industrial

  • Factories
  • Workshops
  • Warehouses
  • Cold stores
  • Car parking sheds
  • Slaughter houses
  • Bulk product storage
Institutional

  • Schools
  • Exhibition halls
  • Hospitals
  • Theaters
  • Auditoriums
  • Sports halls
Commercial

  • Showrooms
  • Distribution centers
  • Supermarkets
  • Restaurants
  • Offices
  • Service stations
  • Shopping centers
Heavy Industrial

  • Cement Plants
  • Steel rolling mills
  • Sugar mills
  • Ceramic factories
  • Recreational
