Why PEB

Why PEB

Components Of PEB

Technological improvement over the year has contributed immensely to the enhancement of quality of life through various new products and services. One such revolution was the pre engineered buildings. Through its origin can be traced back to 1960's its potential has been felt only during the recent years. This was mainly due to the development in technology, which helped in computerizing the design and design.

Though initially only off the shelf products were available in these configurations aided by the technological development tailor made solutions are also made using this technology in very short durations. A recent survey by the Metal Building Associations (MBMA) shows that about 60% of the non residential low rises building in USA are pre engineered buildings.

Although PEB systems are extensively used in industrial and many other non residential constructions worldwide, it is relatively a new concept in India. These concepts were introduced to the Indian markets lately in the late 1990's with the opening up of the economy and a number of multi nationals setting up their projects.

Pre-Engineered Buildings are most economical and fast construction units, which uses a pre- determined raw material that has been proved in the fullness of time to satisfy an extensive range of structural systems with creative designs.

Pre Engineered steel Building is a building shell employing distinct product categories

  • Built- up "I" section to build primary structural framing members ( Columns and Rafters)
  • Cold- formed "Z" and "C" section to form secondary structural members (Roof Purlins, Eave and Wall Girts)
  • Roll formed profiled sheeting ( Roof and Wall Panels)
  • Optional sub systems, which includes mezzanine floors, custom beams and rafters, crane runway beams, roof platforms, catwalks, etc.
  • Custom beams and rafters for unique frames to accommodate the large openings/clear access for ease of operations, which include portal frames, high level mezzanines / 2nd floor, fascia, soffits and other applications.

Types Of Frames

An accessory whose function is to enhance the appearance of a wall and also used to cover the eave or gable of building

A sheet metal closure used to provide weather‐tightness in a structure.

Primary and secondary members (columns, rafters, girts, purlins, brace cables, etc) which when connected together make up the skeleton of a structure to which the covering can be fastened.

Secondary horizontal member attached to the main frame columns. Girts normally support wall panels. It can be z section or c section.

Pre‐formed light gauge metal channel at the roof, along the side walls, or in valleys of multi‐gabled roofs for the collection of rainwater.

A wall opening provided with slanted blades, fixed or movable, to allow flow of air inside the building.

An intermediate floor with in a building above the ground floor that occupies all or part of the building floor area and consists of columns, beams, joists, deck panels and edge trims to receive reinforced concrete.

A piece of roof or wall sheeting.

A horizontal secondary structural member, bolted to the rafters, which transfers the roof loads from the roof covering to the primary frames. This is mostly Z section

A structural frame consisting of members joined together with rigid (or moment) connection so as to render the frame stable with respect to imposed loads, without the need for bracing in its plane

The Ventilator use at the ridge line. Roll‐Up Shutter: A door which opens vertically and is supported on a shaft or drum and runs along vertical tracks.

A door which opens vertically and is supported on a shaft or drum and runs along vertical tracks.

An extension of the roof beyond the endwall and / or sidewall of a building. Roof Monitor: Raised gable, or portion of the main building, located at the ridge, to allow lighting and ventilation.

Raised gable, or portion of the main building, located at the ridge, to allowlighting and ventilation.

A tension member used to limit the movement of a girt or purlin in the direction of its weak axis before the installation of sheeting.

The exterior cover for a building, generally light gage metal, which has been cold formed into a configuration having appearance, weatherproofing and structural qualities.

At translucent panel at the roof/wall to transmit natural light. It is usually made of fiberglass.

A single or double leaf door which opens horizontally by means of overhead trolleys or bottom wheels.

In Pre‐engineered Building distance between interior columns.

A vertical member supporting a wall system designed to withstand horizontal wind loads usually at end walls.

Advantages Of PEB

A steel building system offers significant cost and performance with construction, each part is engineered and designed to assemble together. So, a pre engineered steel building system can be built with greater speed and precision than is generally possible using conventional methods.
