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 the customer's requirements. All the 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 the advantages of low cost, high durability, perfect quality control and fast erection; PEBs are used for various applications such as factories, warehouses, logistics center, showrooms, shopping malls, schools, hospitals, community buildings, etc.
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.
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 the traditional R.C.C (reinforced concrete) building.
Pre-engineered steel buildings are flexible in any requirement of design, easy to expand in the future and also economically with low transportation costs.
Nowadays, pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency, and recyclability.
Pre-engineered metal buildings consist of following components:
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 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.
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 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 by our company during the fabrication, blasting, painting and supply of pre-engineered structure for any of steel building project.
Design and Development department will make the drawings of the structural of project. As per the drawings, production department will prepare the items. The preparation of items is divided into two:
Material is fed into the chamber through conveyor with rubber curtains to prevent abrasive escape.
Application of paint normally done once per day in the afternoon after blasting work completion.
With 20 year warranty in the steel building industry, our company has standard on the quality of steel building. We have acquired the ISO9001 and CE certificate. The followings are the related standard that we strictly follow whether for the design and fabrication of steel buildings:
To ensure the quality of fillet weld, meeting up the technical requirements of welded members and improve the standardization of our fabrication.
This manual applies for the design, fabricate and inspection for the fillet weld size.
Length of catheti from maximum isosceles triangle that drawn from the section of fillet welding seam.
| Form of Fillet Weld Leg | K 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) |
| Parent Metal Thickness (t) (mm) | Minimum Fillet Weld Size |
|---|---|
| t≤6 | 3 (minimum 5 for crane beam) |
| 6 | 5 |
| 12 | 6 |
| t>20 | 8 |
To ensure the welding quality, meeting up the technical requirements of welded members and improve the standardization of our fabrication.
This manual applies for the design, fabricate and inspection of groove joint in terms of manual arc welding, CO2 arch welding, mixed gas arch welding, submerged arc welding and electroslag welding.
Key points on design welding groove:
| Mark | Welding Method | Penetration Type |
|---|---|---|
| MC | Shielded metal arch welding | CJP-complete joint penetration |
| MP | Shielded metal arch welding | PJP-partial joint penetration |
| GC | Shielded arch welding / Self-shielded arc welding | CJP-complete joint penetration |
| GP | Shielded arch welding / Self-shielded arc welding | PJP-partial joint penetration |
| SC | Submerged arc welding | CJP-complete joint penetration |
| SP | Submerged arc welding | PJP-partial joint penetration |
| SL | Electroslag welding | - |
