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.
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.
Price per square meter can be 25%-30% lower than conventional steel buildings. Site erection cost is low due to faster erection times and easier installation process.
All steel components are fabricated at the factory and linked by bolts at the site. 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 buildings.
Pre-engineered steel buildings are flexible in design requirements, easy to expand in the future and economically viable with low transportation costs.
Pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency, and recyclability.
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 application and requirements.
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 with minimum yield strength of 345 MPa (50,000 psi).
Standard steel panels are 0.3, 0.4, 0.5 mm or 0.6 mm thick with minimum yield strength of 345 MPa. Steel panels are hot dipped and galvanized with zinc or zinc-aluminium coating. Base material is pretreated before applying corrosion resistant primer and top coat.
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.
The purpose of method statement is to describe the guidelines and methodology followed during fabrication, blasting, painting and supply of pre-engineered structure for steel building projects.
Design and Development department creates structural drawings. Production department prepares items as per drawings.
Application of paint normally done once per day after blasting work completion. QC inspects blasted surfaces before primer application.
Painting System Specification: Primer coat, Second coat, Third coat per project requirements, with touchup at site after erection.
With 20 year warranty in steel building industry, our company maintains strict quality standards. We have acquired ISO9001 and CE certificates. Related standards we strictly follow for design and fabrication:
To ensure quality of fillet weld, meeting technical requirements of welded members and improve standardization of fabrication.
This manual applies for design, fabrication and inspection of fillet weld size.
Length of catheti from maximum isosceles triangle drawn from section of fillet welding seam.
| Form of Fillet Weld Leg | K (Fillet Weld Size) Value | Note |
|---|---|---|
| Fillet weld without groove | K=(0.7~1)t and ≤15mm | For most steel structure buildings |
| Fillet weld without groove | K=(0.5~0.6)t | For strengthening ribs and secondary members |
| Fillet weld with groove (CJP and PJP) | K=t/4 and K≤10mm | For most steel structure buildings |
| Fillet weld with groove (CJP and PJP) | K=t/2 and K≤10mm | Important members (crane beams or similar) |
Note: t = thinner weld member thickness. For concave fillet welds, actual measured value required to be 1-3mm higher than specified fillet weld foot size.
| Parent Metal Thickness (t) (mm) | Minimum Fillet Weld Size |
|---|---|
| t≤6 | 3 (minimum 5 for crane beam) |
| 6 | 5 |
| 12 | 6 |
| t>20 | 8 |
