What is Pre-engineered Steel Building?
Pre-engineered steel buildings are steel structures built over a structural concept of primary members, secondary members, roof and wall sheeting connected to each other and various other building components.
These buildings can be provided with different structural and non-structural additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, fascias, canopies, crane systems, insulation etc., based on customer requirements. All steel buildings are custom designed to be lighter in weight and high in strength.
Applications of Pre-engineered Steel Buildings
Pre-Engineered Buildings are the most flexible solutions for contractors and owners. With advantages of low cost, high durability, perfect quality control and fast erection; PEBs are used for various applications:
Industrial Applications
Factories
Workshops
Warehouses
Cold Storages
Steel Mills
Assembly Plants
Commercial Applications
Showrooms
Supermarkets
Offices
Shopping Centers
Exhibition Halls
Restaurants
Logistic Centers
Multi-purpose Buildings
Public & Other Applications
Schools
Hospitals
Conference Halls
Laboratories
Museums
Stadiums
Farms
Utility Shelters
Pump Stations
Aircraft Hangars
Airport Terminals
Why Choose Pre-engineered Steel Buildings?
1. Cost Savings
Price per square meter can be 25%-30% lower than conventional steel buildings. Site erection cost is low because of faster erection times and easier erection process.
2. Quick Erection
All steel components are fabricated at the factory and linked by bolts at the site. So the erection process is fast, step by step, easy to install and requires simple equipment. 60% less construction time required compared with traditional R.C.C (reinforced concrete) building.
3. Flexibility
Pre-engineered steel buildings are flexible in any requirement of design, easy to expand in the future and also economically with low transportation costs.
4. Energy Efficiency
Nowadays, pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency, and recyclability.
Components of Pre-engineered Steel Building
Primary Members / Main Frames
Secondary Members / Cold Formed Members
Roof & Wall Panels
Accessories, Buyouts, Crane System, Mezzanine System, Insulation, etc.
Sandwich Panels
Primary Members / Main Frames
Primary members are the main load carrying and support members of a pre-engineered building. The main frame members include columns, rafters and other supporting members. The shape and size of these members vary based on the application and requirements.
Secondary Members / Cold Formed Members
Secondary structural framing refers to purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and other miscellaneous structural parts. Purlins, girts and eave struts are cold formed steel members which have a minimum yield strength of 345 MPa (50,000 psi).
Roof & Wall Sheets/Panels
Standard steel panels are 0.3, 0.4, 0.5 mm or 0.6 mm thick and have a minimum yield strength of 345 MPa. Steel panels are hot dipped and galvanized with zinc or zinc-aluminium coating. The base material is pretreated before applying a corrosion resistant primer and top coat.
Other Building Accessories
Other building accessories include anchor bolts, fasteners (bolts, nuts, turnbuckle, expansion bolts), gutters, downspouts, doors, windows, ventilators, skylight panels, louvers and all other building-related materials.
Manufacturing Process & Quality Control
A: Material Receiving Procedure
Verify receiving documents and material quantity
Submit for QC inspection
Visual inspection for surface condition and damages
Issue fabrication drawings to production supervisor
Collect prepared beams and connection details
Fix end plates, gusset plates, stiffeners, purlin cleats
Tack welding in appropriate places
QC inspection after fit-up completion
D: Welding & Grinding
Submerged Arc Welding Procedure:
Plan jobs for welding
Clean welding locations free of dust, oil, grease
Set wire feed and voltage parameters
