Pre-Engineered Building Installation Services
A main advantage of steel frames is their capability of covering huge spans with lesser cost than concrete frames.
The pre-engineered metal building system is a building enclosure system that always includes a structural system and often includes roof and wall cladding. The general idea of the system is represented in the diagram below. The structural system consists of rigid frames that are fabricated from plate steel and “cold formed” into an “I” shape through a manufacturing process. These rigid frames consist of roof beams and columns that are field bolted together. These frames can span large distances without intermediate supporting columns. The frames are spaced at intervals between 15’ and 60’ and can span, column-free, up to 300’ across a building

- Seismic resistance
- Ease of expansion
- Large clear spans
- Maintenance free
- Highest quality checks
PEB Erection and Sheeting Procedure.
Ground Condition / Site preparation:
- Visit to site and understand the ground conditions suitable for erection.
- Identification of space in consultation with client near to the structure for unloading of material and for painting.
- Firm Floor surface and ramp for movement of crane within the building area.
- 3m wide plain surface all around the periphery for the movement of scaffolding.
- Source of electricity and water supply for sheeting and water testing purpose.
- Provision for labour accommodation within or near the site.
- Suitable storage arrangement to be provided by the client for safety & security of fasteners and other small materials.
Log book is maintained at the site by the supervisor which contains:
- No. of working staff per day per activity.
- No of hoisting equipments, tools tackle machinery etc.
- Details of material received (load wise), date, discrepancy if any as mentioned on the back side of LR Copy.
- Painting, equipments & labour.
- Erection/Activity status report (date wise)..
- Anchor Bolt setting Report.
- Torque tightening Report.
- Alignment Report.
Roof, Wall cladding and Finishing
Before starting any sheeting work, we check for complete alignment of the portion of structure to be sheeted and submit alignment Report to the PEB. Supplier’s Engineer.
- Calculation of manpower and machinery required for the sheeting area.
- Mobile scaffold to carryout the wall cladding.
- Sufficient props or wooden supports to be provided from ground level for grits which are sagging before cladding.
- All purling to be straightened before roof sheeting.
- Proper scaffold or firm ladder /staircase to reach the roof top.
- Check the diagonals of the first layer of sheets both for roof and wall cladding.
- Proper method of screwing of roof as well as wall sheeting.
- Fixing of mastic tape for roof sheeting with proper overlaps of sheets as specified.
- All flashings & trims are properly lapped and aligned.
- All closures are properly sealed and screwed such that they are firmly fixed.
- Gutter and downspouts are aligned properly.
- For tightening of screws, screwing machines with depth gauge sockets are used.
- Life lines fixed such that all sheeting team working at heights use it for hooking the safety harness belt.
