Pre Engineered Buildings

INTRODUCTION OF BANSAL’S PRE-ENGINEERED STRUCTURES:

  • Pre-Engineered Building is a concept of structure having high structural strength, economical design while it supersedes the conventional fabrication, it lowers down the stress of foundation, hence there is less cost on civil construction as well.
  • Tailor made buildings based on client’s requirement and actual design calculations using tapered sections. An efficiently designed Pre-Engineered Building can be lighter than the conventional steel building by up to 30%.
  • BANSAL is well equipped to produce Pre-Engineered Buildings as per client’s requirements. The company has all the latest machinery to support this segment. The entire design of Columns, Rafters and other Accessories is based on international structural standards and invoice high technical welding and quality production.
  • These are the structures basically manufactured/fabricated at the factory with the high tensile steel material by collecting complete information of shed/building (viz: Length, Width, Height etc.)

PEB comprises of –

a) Primary Members include:

Columns, Rafters, Crane beams, etc.

b) Secondary Members include:

Purlins, Bracings, Tie rods, Angle bracings, High Tensile Bolts and washers etc.

c) Roofing, Cladding & Accessories include:

Top Roof Sheets/Panels , Side Cladding (Vertical) Sheets/Panels, Skylights Sheets, Ventilators, Louvers, Downspouts, etc.

Advantages:

  • It is designed using international standards considering factors like weather conditions, wind Velocity, seismic zone etc. of the location.
  • We design Energy Efficient buildings using skylight sheets, cladding louvers, Self-driven ventilators, Ridge vents, Roof Monitor design and many more.
  • High aesthetic appeal using latest design of Gabble End, Curves, Bracket less Gutters etc.
  • Flexibility in expansion.
  • Saving in construction time.

APPLICABLE DESIGN CODES:

We at “Bansal” use international design codes for making Steel Buildings. It is in accordance with the following codes:

  • The 2002 Edition of Low Rise Building System Manual of Metal Building Manufacturer
  • Association (MBMA)
  • All Applicable loads of design as per MBMA
  • Hot rolled and build up sections are designed in accordance with: Manual of Steel Construction,
  • 9th Edition of American Institute of Steel Construction (AISC)

  • Cold formed members are designed in accordance with 1996 edition of Cold formed Steel
  • design manual of American Iron and Steel Institute (AISI)

  • Welding is applied with in accordance with Structural Steel Welding code of American Welding
  • Society (AWS D1.1)

  • We also manufacture Structure based on Design Codes as per Indian Standards.
