Pre - Engineered Buildings can be as unique as your needs. A computer assisted design helps to create a building for a specific use. Pre-engineered buildings are the state-of-the-art steel solution to develop an efficient and cost-effective infrastructure. PEBs offer ultimate design flexibility and an extremely short construction time (right from initial design to completion). They are supplied as a fully finished product along with steel structure, building accessories and roof cladding. They require no on-site fabrication or welding they can simply be bolted together as per specifications. PEBs are best suited for warehouses, sports halls, factories, workshops, distribution centers, cold storage, supermarkets, aircraft hangars or any ground t-storey construction.

We Specialize in PPGI and PPGL Sheets which are made of world class raw material compiling with the most preferred material for various construction purposes, particularly roofing and wall cladding. Coated steel sheet is a unique building material that combines the strength of steel with excellent corrosion protection of zinc or zinc / aluminum alloy coatings. It can be punched, pressed, roll formed and joined into a countless number of structural and decorative building products. Our PPGI and PPGL Sheets are available in various colors - sky blue, royal blue, azurite blue, terra cotta red, off white and mist green etc...

At Ferrweld, practically any type of geometric frame can be built. Some of the most commonly used primary framing systems are featured here.

Our Turbo Ventilators does not require electricity or no operating cost it is a unique design with FRP opaque ventury will give lighting during day time. The rotor rotates on natural wind velocity. This unit is installed at a distance of 15ft x 15ft on the roof of industrial sheds and single unit will coverage 225sq.ft inside area and reduces 3 to 7C the inside area room/hall temperature. After installation as it is zero maintenance unit and easy to install on any type of roofing. The Ferrweld Turbo ventilators are of standard Size 24 inches. The fan is made of aluminum and the connector is of Stainless steel and the base plate is of FRP Sheet. Skylights Skylight is any horizontal window, Roof lantern or Oculus, placed at the roof of the building, often used for daylighting. White translucent acrylic is a 'Lambertian Diffuser' meaning transmitted light is perfectly diffused and distributed evenly over affected areas. This means, among other advantages, that light source quality standards are measured relative to white acrylic transmission. White acrylic domes provide even light distribution throughout the day. Skylights admit more light per unit area than windows, and distribute it more evenly over a space. The optimal area of skylights (usually quantified as "effective aperture") varies according to climate, latitude, and the characteristics of the skylight, but is usually 4-8% of floor area. The thermal performance of skylights is affected by stratification, i.e. the tendency of warm air to collect in the skylight wells, which in cool climates increases the rate of heat loss. During warm seasons, skylights with transparent glazings will cause internal heat problems, which is best treated by placing white translucent acrylic over or under the transparent skylight glazing. Skylights can also double for natural ventilation systems. Skylights can also double for natural ventilation systems. With proper skylight design, there can be significant energy savings in commercial and industrial applications. Savings from daylighting can cut lighting energy use by up to 80 percent according to the US Department of Energy's Federal Energy Management Program. In terms of cost savings, the DOE reported that many commercial buildings can reduce total energy costs by up to one-third through the optimal use of daylighting.
