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 centers, 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.
Once cleaned, the material is fed into the chamber of the automated machine through the conveyor. The chamber consists of both in & outlet vestibules, on which hung rubber curtains, which serve to prevent the escape of abrasives during the blasting process.
Application of paint shall normally be done once per day in the afternoon, once the day's scheduled blasting work is complete. Prior to the application of the primer, the QC shall inspect the blasted surfaces to check the required standards in the approved ITP have been met. Any area(s) deemed to have fallen short of the required standard will require re-blasting either by being driven through the blast chamber again, or by Injection blast gun if possible, whilst still on the out-feed rack. Any 'sweep' blast done by mini pot will utilize copper slag as the abrasive.
Once the blasted surface has been accepted by QC, application of the primer can commence, provided ambient conditions checks prove satisfactory. These must be checked and recorded before any and every application. In order for coatings to proceed, the surface must be at least 3˚C above the dew point temperature, and the relative humidity must be 85% or below. Surface must be dry and free from oil, grease and soluble salts, protrusions, sharp edges, or visible laminations, and not exceed 40˚C in temperature.
Before application QC should do the inspection of the atmospheric conditions according to GB50205-2001 Standard Grade:
Paint shall be applied wherever possible by means of Airless spray. The paint material will be checked for conformity with shelf life restrictions, temperature and batch number. Mixing ratio, tip size and method of agitation shall be checked by QC to ensure adherence with the approved ITP and Paint Manufacturer's recommendations. Pot life will also be monitored once mixed. Only experienced spray applicators shall be used for the application of paint materials, and all shall wear appropriate PPE for the job.
During the application, the spray applicator shall take WFT (Wet Film Thickness) readings in accordance with the approved ITP to ensure his target WFT is being achieved. Spot checks by QC will be made to verify conformity.
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:
Note: The following sections contain detailed technical specifications and standards for welding processes and quality control. These are provided for technical reference and demonstrate our commitment to quality manufacturing standards.
