DESIGN After receiving architectural drawings, engineers will design the super structure with designated software and the drafting department produce shop drawings and structural drawings. The optimum design with Cold Formed Steel (CFS) system by itself is up to nine floor building. To achieve higher floors can mix hot-rod structural steel with CFS system.
TECHNOLOGY The software also produce data for state- of-art roll-forming machine at plant and they produce steel studs (500m/hr). Then fabrication crew will take those studs according to shop drawings and fabricate wall panels (1000m² per day). To ensure construction schedule, wall panels can be fabricated ahead of site erection sequence and stored.
PRODUCTION PROCESS The process involved in producing FCF wall panels are: Design: Experience engineer with designated software program will design entire building with CFS system. The program will produce wall panel's detail data. Roll-Forming: Wall panel's data insert to roll-forming machine’s computer by operator and start producing steel studs by bending and folding flat sheet of galvanized steel which coming by de-coiling the galvanized steel coil. Machine produce all studs related to a wall panel and mark them by printing codes on every stud. Panelizing: The software also produce shop drawings. Crew of two or three (depend the size of wall or volume of work) will pick those studs one by one and fabricate wall panel by screwing studs together. According to design, fasteners also will use in different section of the wall panel. Quality Control: In this area QC manager will check the wall panel according to shop drawing to make sure all screws and fasteners all in the right place and wall is dimensionally square. Loading: According to erection drawing, wall panels stacked at loading area by gantry crane on trailer and ship to the jobsite. Open Web Steel Floor Joist: Light gauge joist production process is like wall panels. Galvanized Steel Coil: There are many companies supply steel coil around the world. Galvanized steel sheet is widely used in automotive and home appliance manufacturing. Turkey, South Korea, Japan and China are the key player in the market. Some have local representative in Dubai and Doha. Screws and Fasteners: there are few types of screw will be used in CFS system which is common in steel industry and there are many suppliers in the region.
ENVIRONMENTAL / RESOURCE IMPACTS Fabricating wall panels is zero emission and produce no waste. All the knockouts from machines in plant and alteration pieces at site will be collected and send back to mills to produce new steel.
ERECTION The wall panels ship to the job site and hoist one by one with light crane and with small crew on ten erect the superstructure. Floor system component also ship to the site and install with the same crew (350m2 per shift). CFS system applies to different type of construction projects such as modular buildings, offices, labor accommodations, oil and gas compounds, low and mid-rise apartments and condominiums, villas, army barracks, schools, police stations, hotels and motels, vertically add-on floor to existed building, medical offices and hospitals, senior care facilities etc.
Benefits of Cold Form Steel Framing System
Cost Stability: CFS system use galvanized steel for its components. Steel as commodity shown historically has minimum price fluctuation. There is less concrete volume use in FCF designed floor system compare to traditional methods. For interior and exterior walls there is no need of masonry units so price spikes in raw material such as gravel or cement wont effect CFS type of construction. Light weight: Steel has the highest strength-to-weight ratio in all construction material. CFS building system is lighter about 50% compare to concrete sys. Lighter building system means saving in construction cost and maintenance. Saving on foundation cost and seismic design and on Issues related to building settlement such as cracking on interior and exterior walls. Panelized: Walls assembled at FCF plant in controlled environment efficiently and accurately. Dimensionally correct components increase building quality. Speed of Construction: Faster construction schedule by 40% compare to traditional methods. Crew of 10 can erect 350m2 of building in one shift per day! Modular Buildings: CFS building system is most suitable for mobile type buildings as temporarily accommodations such oil and gas field, natural disaster shelter, solder barracks, police station and many more. Seismic Design: Steel is ductile material which tend to bend and not break like concrete. In seismic events, lighter building system, ductility of steel and flexibility CFS connections keep building intact and save lives. Simple Assembly: us.ng pre-fabricated light structure components with small tools make it easy to handle and construct at jobsite. Skilled Labor Shortage: all wall panels are coded from plant and match floor layouts so it's easy to install at site with simple training despite language brier and level of education. Other Crews Schedule Overlap: one of the unique characteristic of CFS system Is Independency from too many props during construction like concrete system. Open space on every floor during the construction allows other crews such as mechanical and electrical follow the superstructure team exactly one floor below and finish project faster to achieve earlier occupancy. Safer Job Site: As soon as exterior wall panels erected, become fallprotection barrier for workers. Window openings blocked by temporary steel straps for more protection from plant.
Less Manpower: All concrete pour-stops around the edge of building and floor openings are steel components and supply by FCF so there is no carpentry and woodwork and their waste!
Benefits of Cold Form Steel Framing System
Fire &. Sound Rating: steel is non-combustible. For walls and floor assemblies, SBS utilize approved detailed assemblies by local and international authorities with proper fire and sound specification. Waste and Waste management: using pre-fabricated and cut-to-length superstructure components make minimum waste at plant and site. There is considerable amount of saving on waste removal and environmental impact. Durable: CFS galvanized steel component, according to study, can last more than 100 years. Healthier Building: Steel is inorganic material and won’t host of any fungi organism. Steel won't add any fume to living space. Thermal Function: Because of CFS design nature, walls and floor system has very high thermal performance based on assembly features such as cladding materials with proper insulation. Confirmed wall and floor assembly thermal performance are available. Green Building: using recycled steel as raw material and being recycled after lifecycle, minimum waste, regionally made (UAE), high thermal performance and healthier living environment and minimum emission make CFS system a green building technology. Design Ideas: CFS building system can have long spans between two load-bearing- walls with no dependency on columns and gives architects a unique experience on design space flexibility. Easy To Build And Dismantle: Using light and easy to handle With ready-to-use finishing building materials makes it easy to construct and demolish buildings on temporary requirements such as tempaccommodations or buildings related to events such as sport games or Dubai Expo. Dry Building Site: Use of Pre-fabricated building components such as wall panels, ready-to-use gypsum and cement boards and cladding material, make FCF job sate dry with minimum air pollution and noise disturbance. Less environmental impact. Economy: More than 40% of new steel is recycled old steel and has effect on raw material price stability and performance
