Pre-Engineered Buildings


Pre-Engineered Buildings

Pre Engineered Buildings are the state of the art steel solution for developing an efficient and cost effective infrastructure. Pre Engineered Building is a steel structure, built over structural concept of primary member. Secondary member and the cover sheeting are connected to each other. PEBs can be fitted with different structural additions like Trusses, Mezzanine floors, Fascias, Canopies and Crane systems as per clients’ requirements.

We have our own PEB manufacturing plant at Ghaziabad. Our services range from conceptualizing to designing, manufacturing, finally supply and erection. Rainbow PEB are customized to meet exact requirements using steel structure, beams and columns, profiled sheets, Z and C sections, steel decking sheets, insulated sandwich panel and other building accessories.

Salient Features
  • PEBs offer ultimate design with flexible and extremely short construction time
  • Low initial cost
  • Superior product quality matching with International Standards
  • Aesthetically appealing
  • Fast modular expansion

PEB Vs CONVENTIONAL STEEL BUILDING
  • The designing of PEB is quick and efficient as they are made of standard connections and sections
  • PEB can be delivered within 7 weeks as compared to conventional building requiring 20 to 25 weeks.
  • PEB’s are much more economical.
  • In contrast to PEB’s conventional steel buildings require enormous labor and heavy equipments.
  • PEB’s offer single source responsibility for design and erection.
  • Future changes can be more easily incorporated in PEBB’s as compared o conventional.

Primary Structure
They are the main load carrying and support members of PEB. The shape and size vary based on application and requirements. It includes Rigid frame, Beams, Columns, Canopies etc. Beams and columns use high strength steel plates which make the structure light and economical. Rainbow beams come in a wide range of flexible sizes, are supremely cost effective and offer cutting edge quality. Rigid Frame is composed of two columns and two sloped beams which support the roof of the building. This is the form upon which sheeting is placed to form a building. Beams and Columns provide additional support allowing larger building width and economical designs.

Secondary System
Cee and Zed Purlins are secondary members of steel structure. They are the load carrying members suitable to ensure the stability of the building against forces in any direction. These purlins are characterized by high strength, yet low cost (as a result of high strength to weight ratio).

Advantages of Rainbow C and Z Purlins
  • More than 40% saving in steel
  • More than 30% saving in overall construction cost
  • Reduced installation time
  • No site drilling or cutting required
  • Purlins are factory finished, tailor made with pre punched holes to avoid wastage of time

Roofing and Cladding
Rainbow PEBs offer you choice of 4 different types of roofing and cladding systems that enhance the aesthetic appeal of the building and are ideally suited for rapid and low cost construction. Galvalume sheets are one of the finest choices for roofing and cladding.

We also offer Rainbow Daylight Profile – It is a rigid polycarbonate transparent roof glazing sheet available in required lengths. It offers light transmission between 50% to 90% depending on its thickness and is available in clear as well as embossed quality. In addition to the main building, we also provide a wide range of building accessories such as Walk doors, Sliding doors, Aluminium windows, Power ventilators, Wind ventilators etc.

Rainbow Wind Operated Turbo Ventilators
With our vast industry experience we are engaged in offering our clients with Wind operated Turbo Ventilators. It is a natural, economical and effective way for exhaust of air round the clock without operating costs. It is installed on the roof the wind, the stale air inside is exhausted and a natural boosted. Ventilators prevent the build up of summer heat in roofs and thus reduce the cost of energy for cooling .In winters vents eradicate the build up of moist cavities that may contribute to a variety of structural problems.

Rainbow Roof Extractor
We also provide Rainbow roof extractor which is a motor driven fan unit and is provided with durable weather proof exhaust hood. This is ideal for extraction of air supply through the roof, usually preferable in Factories, D.G rooms, Steel plants and Foundries
