Product Overview

Pre-engineered Structural Steel Industrial Real Estate Building Construction

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.

Public: Schools, Hospitals, Conference Halls, Laboratories, Museums, Stadiums
Others: 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

Pre-engineered metal buildings consist of following components:

  • 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.

Low Cost Pre-engineered Steel Building with 50 Years Life Cycle and Quick Erection
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) and will conform to the physical specifications of GB/ISO/CE or equivalent.

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. The combined thickness of the painted film is 25 microns on the front side and 12 microns on the reverse side.

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

The purpose of method statement is to describe the guidelines and methodology followed by our company during the fabrication, blasting, painting and supply of pre-engineered structure for any steel building project.

A: Material Receiving Procedure
  • Verify the receiving documents and quantity of the received material by stores
  • Submit the load for QC inspection by stores
  • QC performs visual inspection to confirm surface condition and check for damages
  • QC performs dimensional inspection if material passes visual inspection
  • Verify supporting documents like MTC to ensure heat number matching
  • QC prepares Incoming Material Inspection Report
B: Preparation of Material

Design and Development department makes project drawings. Production department prepares items as per drawings:

Preparation of Plates:
Drawings transferred to storage device using expert software
Drawings copied into plate processing machine
Automated machine processes plates according to NC files
Punching of part mark, drilling, and plasma cutting performed
Preparation of Beams/Tubes:
Fabrication drawings prepared by design department
Automated cutting and drilling machine processes components
Job transferred to fit-up section after completion
C: Fit-up

Fabrication drawings issued to production supervisor for execution. Prepared beams and connection items collected for fit-up. End plates, gusset plates, stiffeners, purlin cleats, stay angle cleats fixed in appropriate places by tack welding.

Set wire feed and voltage for welding
Maintain fillet size parameters per GB50661-2011 standard
Remove spatters and slag after welding
Grind off burrs, sharp edges and excessive reinforcements
Offer to QC for inspection
Procedure - MIG Welding:
Plan jobs to be welded
Clean welding locations free of dust, oil, grease
Set wire feed and voltage for welding

E: Blasting

Tool Box Talk performed by Foreman for every task. Working area barricaded with information notices. ID of fabricated steel recorded for traceability.

Handling & Preparation:
Raw material steel sections craned onto "in-feed" rack
Material cleaned with high pressure air to remove dust
Material fed into chamber through conveyor
Automated Blasting:
Six internally mounted wheels rotate at high speed
Steel shot thrown at high velocity onto steel substrate
Structural beams move slowly through chamber
