Two Storey Steel Structure Building lateral contrast points
Compared to traditional reinforced concrete buildings, the Two Storey Steel Structure Building utilizes the high strength-to-weight ratio of steel, significantly reducing the cost of the foundation and significantly shortening the return on investment cycle. The following are specific solutions to the pain points of traditional buildings:
Solve the pain point of long project investment return period
The construction period of traditional concrete double-deck building usually takes 6-10 months, which is greatly affected by the weather. This product adopts factory prefabrication and on-site full bolt assembly mode, which is not restricted by seasons, shortens the overall delivery time to 3-4 months, helps enterprises put into operation half a year in advance, and quickly returns funds.
Solve the pain point of high cost of soft soil foundation.
The double-layer concrete building has great self-weight and high requirements for foundation bearing capacity. The steel structure product weight is only 1/3 of the same area of concrete buildings, significantly reducing the foundation load, can save about 30% of the foundation excavation and concrete pouring costs, especially suitable for the general geological conditions of the region.
Solve the pain point that the space layout is limited and cannot be transformed.
There are many load-bearing walls in traditional buildings, and the internal space is divided and fixed, so the later transformation is extremely difficult. This product adopts frame structure system, no load-bearing wall inside, and with a column distance of more than 9 meters, the purchaser can freely re-divide the partition or increase the equipment assembly line in the future business expansion without destructive removal.
Two Storey Steel Structure Building Target audience
Production-oriented manufacturing business owners
Suitable for factories that need “lower production, upper office” or “lower storage, upper assembly” mode. The high-floor load-bearing design meets the installation of heavy machinery, and the double-layer structure maximizes the use of limited industrial land area.
