Pre engineered building

• Pre Engineered Building is a metal building
  enclosure system that often involves a structural
  framework and also involves roofing and wall
  cladding and is built and assembled in the
  factory premises.
• The main reason for the adoption of PEB in India
  is the continued faith in conventional
  construction methods.
• PEB is manufactured using the raw materials
  available from all sources and manufacturing
  methods that can effectively meet a wide range of
  structural and esthetic design requirements.

• Historically, the primary structure of the pre
  engineered building is the assembly of I-shaped
  members, often referred to as I-beams.
• In pre engineered buildings, the beams used are
  typically formed by welding steel plates together
  to shape the I segment.
• India is a developing country, and construction
  plays an important role in India 's development
  as a result of the rapid growth of prefabricated
  structures.
• Government plans for many projects every year,
  such as smart cities, malls, hospitals , schools,
  bridges, metro stations , airports and many more.
  Such construction projects of the Government are
  often on a wide scale.
• Even the Warehousing sector in India is rising at
  a rate of 35-40 per cent per year.

• Fast construction, cost-effectiveness,
  reliability, reusability and design versatility
  are some of the main advantages of PEB.
• From a basic structure to complex high-rise
  structures, PEB has built its reputation.
• This is the main reason why everyone chooses
  prefab construction for personal and government
  projects.
• There are several PEB companies in India offering
  world-class steel construction solutions on a
  regular basis in the construction industry and
  DHUMAL METALS PVT.LTD. is one of them.
• DHUMAL METALS PVT.LTD has vast experience in the
  manufacture of all forms of steel structures and
  also focuses on the quality of the products.

Time Cost Saving 

• Any PEB project would save time and money to the
  consumer that is critical in today's busy
  schedule.
• In prefab construction, after the manufacture of
  all steel products by the manufacturer of PEB,
  all products are shipped to the construction
  site.
• Installation can be done in a matter of days or
  weeks.
• Installing a prefabricated structure requires
  less labour, as a result of which labor costs are
  often small.

7

• This cycle of processing, transport and
  installation takes less time than conventional
  construction.
• When the project is on a wide scale, the
  purchaser of steel may buy in bulk and, as a
  result , the cost of steel is also lower. This
  costs less, thus, which benefits the consumer

PEB STRUCTURE COMPONENTS

• Primary Frame.
• Secondary Structural Elements.
• Roof and Wall Panels.
• Sandwich Panels.
• Other accessories.

10
Primary frame

• Pre-engineered steel building is a portal frame
  structure consisting of a main and secondary
  frame and bracing system.
• The combination of these three components and the
  weather-covering of the sheeting results in
  robust steel buildings instead of individual
  frames.
• In the case of modern structures, individual
  columns and trusses are individually built and
  free standing frames resulting in a bulky and
  heavy structure.

11
COLUMN RAFTER CONNECTION

• Functional need of the framing system, column to
  RS connection can be constructed in a number of
  ways.
• There are different merits and demerits in each
  option of the rafter-column system, as steel
  consumption still continues to vary in each
  option.
• It is also important for the designer to opt for
  this For economic relation, unless there are any
  practical limitations.

12
Secondary structural elements

• the secondary framing system consists primarily
  of purlin and z or c shapes of various sizes.
• In pre-engineered buildings usually cold form Z
  sections are used for secondary frames to achieve
  high strength and lower weight.
• Usually cold process components used for roofing
  are called purlin and for walls it is called
  girt.
• Sometime C section is often used instead of Z.
  Purlin / Girts are members who transfer forces
  and moments from one frame to another for the
  overall stability of the building structure and
  all act as a weather-covering system for the
  purpose of sheeting.

13
Roof and wall panels

• Tin shades Curtain Wall made of glass
  roll-shaped steel sheets typically come in this
  category.
• For the transfer of wind force and other acting
  loads form the building frame to the base at a
  certain interval, the x-bracing system is used to
  change the direction of forces in order to reduce
  the impact of forces.
• The 2nd and 2nd last bays are preferably designed
  as braced bays and, for economic reasons, braced
  bays between every 4th bay.

14

• These braced bays are for the roof as well as the
  wall between two frames (bays).
• Normally, rods, pipes or angles are used for
  x-bracing purposes. In the wall bracings, two
  columns form a haunch to the bottom of the
  columns.
• Sandwich panels The sandwich panel consists of
  three layers in which the non-aluminum core is
  inserted between two aluminum sheets.
• accessories mezzanine flooring, bolts,
  insulation, etc.
