Primary frame
Columns and rafters
Plate-welded H and I sections, tapered where the loads are lower, form the portal frames that carry the building.
A&A Enterprises Engineering · PEB
Pre-engineered buildings
Steel buildings designed for your span, height and loads, fabricated in parts, and bolted together on site on a foundation we build. One contractor from drawings to handover.
What a PEB is
A building designed as a kit
A pre-engineered building is a steel structure designed for one specific building, cut and welded in a workshop, and bolted together on site. Because the parts are made while the foundations are being built, the building goes up quickly once the concrete is ready.
Secondary frame
Purlins and girts
Light cold-formed sections span between the frames to support the roof and wall sheeting, braced against wind.
Envelope
Roof and wall sheeting
Profiled steel sheets, single skin or insulated sandwich panels, with gutters, flashings and ridge vents.
Accessories
Doors, vents and skylights
Roller shutters, sliding doors, windows, louvres, translucent sheets and turbo ventilators.
Options
Cranes and mezzanines
Crane beams for EOT and gantry cranes, mezzanine floors, canopies and fascias, designed into the frame.
Foundation
Civil works by us
We design and build the footings, plinth and floor slab, so the structure and the base are one responsibility.
How a PEB project runs
From sketch to handover
- BriefUse, size, eave height, cranes and any mezzanine. A sketch and the site location are enough.
- DesignWe design the frame and foundations for your loads and send drawings for approval.
- FoundationsFootings, plinth and anchor bolts are built on site while the steel is fabricated.
- ErectionFrames, purlins and bracing go up, then the roof and wall sheeting.
- HandoverDoors, accessories and finishing works, then a ready-to-use building.
Erection
Portal frames going up
- Primary frame
- Bolted connections
Frames are lifted onto anchor bolts cast into the foundations, plumbed and braced before the purlins go on.
Completed
Industrial sheds and warehouses
- Clear span
- Insulated roof
Completed buildings for storage and production, with roller shutters, translucent roof panels for daylight and masonry plinth walls.
Building types
What we build as PEB
Industry
Factories and production halls
Column-free floors for machine lines, with crane beams where needed. See our industry examples on the main engineering page.
Storage
Warehouses and cold stores
High clear heights for racking, dock doors, and insulated panels for temperature-controlled storage.
Defence and public sector
Hangars, depots and vehicle sheds
Workshops, MT sheds, hangars and stores for government and military clients, delivered to specification.
Agriculture
Poultry, dairy and grain sheds
Ventilated, insulated sheds for livestock, and tall stores for grain and rice.
Questions
PEB FAQ
01 · FAQ
How long does a PEB take to build?
It depends on size, design approval and the site. Because the steel is fabricated while the foundations are built, the building usually goes up far faster than a concrete structure of the same size. We give a programme with every quote.
02 · FAQ
How wide can a PEB span without columns?
Clear spans of 30 to 60 metres are routine, and wider buildings use multi-span frames with a line of internal columns. We design the span around how you will use the floor.
03 · FAQ
Can a PEB carry an overhead crane?
Yes. Crane beams and brackets are designed into the frame for EOT and gantry cranes, and the columns and foundations are sized for the crane loads.
04 · FAQ
Can solar panels go on a PEB roof?
Yes, if the roof is designed for the extra load. Our sister company Mastoor Energy has fixed solar arrays to PEB roofs, for example at Desert Hawk, Hyderabad.
05 · FAQ
What does a PEB cost?
The price depends on the span, height, wind and crane loads, the sheeting and insulation, and the foundations. Send us the size and use and we will quote.
