Comparison between Pre-Engineered and Conventional Building.
| Properties | Pre-Engineered Steel Building | Conventional Building |
| Structural Weight | Pre-engineered buildings are on the average 30% lighter because of the efficient use of steel.Secondary members are light weight roll formed "Z" or "C" shaped members. | Primary steel members are selected hot rolled "T" sections. Which are, in many segments of the members heavier than what is actually required by design. Secondary members are selected from standard hot rolled sections which are much heavier. |
| Design | Quick and efficient design since PEB's are mainly formed by standard sections and connections design, time is significantly reduced. | Each conventional steel structure is designed from scratch with fewer design aids available to the engineer. |
| Construction Period | Average 6 to 8 weeks | Average 20 to 26 weeks |
| Foundation | Simple design, easy to construct and light weight. | Extensive, heavy foundation required. |
| Erection and Simplicity | Since the connection of compounds is standard the learning curve of erection for each subsequent project is faster. | The connections are normally complicated and differ from project to project resulting tin increasing the time for erection of the buildings. |
| Erection Time and Cost | The erection process is faster and much easier with very less requirement for equipment | Typically, conventional steel buildings are 20% more expensive than PEB in most of the cases, the erection costs and time are not estimated accurately. Erection process is slow and extensive field labour is required. Heavy equipment is also needed. |
| Seismic Reistance | The low weight flexible frames offer higher resistance to seismic forces. | Rigid heavy frames do not perform well in seismic zones. |
| Over all Cost | Price per square meter may be as low as by 30 % than the conventional building. | Higher price per square meter. |
| Architecture | Outstanding architectural design can be achieved at low cost using standard architectural details and interfaces. | Special architectural design and features must be developed for each project which often requires research and thus resulting in higher cost. |
| Future Expansion | Future expansion is very easy and simple. | Future expansion is most tedious and more costly. |
| Safety and Responsibility | Single source of responsibility is there because the entire job is being done by one supplier. | Multiple responsibilities can result in question of who is responsible when the components do not fit in properly, insufficient material is supplied or parts fail to perform particularly at the supplier/contractor interface. |
| Performance | All components have been specified and designed specially to act together as a system for maximum efficiency, precise fir and peak performance in the field. | Components are custom designed for a specific application on a specific job. Design and detailing errors are possible when assembling the diverse components into unique buildings. |
Our excellent design team will design the steel structure building for you. We can quote If you give the following information.
| 1 | Location (where will be built? ) _____country, area |
| 2 | Size: Length*width*height _____mm*_____mm*_____mm |
| 3 | Live load on roof(KN/M2), live load on second floor(KN/M2) if have |
| 4 | Wind load (max. Wind speed) _____kn/m2, _____km/h, _____m/s |
| 5 | Snow load (max. Snow height) _____kn/m2, _____mm |
| 6 | Anti-earthquake _____level |
| 7 | Brickwall needed or not If yes, 1.2m high or 1.5m high |
| 8 | Thermal insulation If yes, EPS, fiberglass wool, rockwool, PU sandwich panels, Corrugated steel sheet with fiber glass wool will be suggested; If not, the Corrugated steel sheet will be ok. The cost of the latter will be much lower than that of the former. |
