Q235B Q355B Steel Structure Construction / Metal Frame Construction Painting Surface
Metal Frame Construction / Industrial Steel Structures / Structural Steel Frame Construction. We could contract the projects such as prefabricated steel structure warehouse, workshop, storage sheds, garage, hangar, chicken shed, car parking, showroom, office buildings, gym, dormitory building, high rise steel residence buildings, oli&gas project, power station, infrastructure buildings, etc. The major factors that effect the budget of prefabricated steel structure buildings are as below:
1. The height of the building, according to actual needs, increases the construction cost by 2% to 3% for every 10cm increase.
2. With or without crane tonnage, the choice of crane tonnage is also a big deal. If the tonnage selected is too large, it will cause waste of equipment, which is too small to meet the construction needs. Of course the price is different.
3. The protection structure, this is also the cost to consider, such as doors, windows, exterior walls and so on.
4. The type of the design structure of the factory building in the location, the building time, the use and other related factors.
5. The size of the construction area is the most essential influence. The large area must have a large amount of steel, and the cost of the steel structure factory building is relatively high. The width determines the area, and of course, it is also closely related to the structure of the plant design.
6. The length of the steel structure span, generally speaking, the larger the span, the lower the cost. Of course, the span is arranged according to its own needs, the design is different, the span is also different, of course, the requirements of the column distance are also very different.
7, the amount of steel required, the steel structure factory building cost has the greatest impact on the amount of steel. In addition to the source of the steel, the imported ones are also different from the domestic ones, and the color steel plates or sandwich plates are also different. On the same material, the area that has the greatest influence on the amount of steel is its area. The size of the building area determines the amount of steel used. Of course, the design of the structure is also within the scope of influence.
