Professional Q&A for Bolted Structure Container House
Q1: What is the core advantage of 8.8 bolt structure compared with ordinary bolt & welded structures?
A: 8.8-grade high-strength bolts have far higher tensile and shear strength than ordinary bolts, avoiding loosening and deformation. Different from pure welded structures that are difficult to repair and prone to welding seam cracking, the bolted assembly structure supports local disassembly, replacement and maintenance, with higher structural stability and longer service life.
Q2: Will the 8.8 bolt connection affect the overall airtightness of the container house?
A: No. The product adopts precise hole position matching and auxiliary sealing technology. The bolt locking structure fits tightly with the frame, which will not cause gaps or air leakage. The overall airtight and heat preservation performance is consistent with the integrated welded container house.
Q3: Is the bolted folding container house suitable for long-term outdoor stacking?
A: Absolutely suitable. The optimized 8.8 bolt stress dispersion design can stably bear double-layer and three-layer stacking load. With excellent anti-loosening and anti-aging performance, it can maintain stable structural performance during long-term outdoor stacking deployment.
Q4: Does the 8.8 bolt structure increase on-site assembly difficulty?
A: No increase in difficulty. The product is pre-positioned and pre-opened in the factory. The on-site assembly only needs simple bolt locking operation, no professional welding technology and equipment required. The overall assembly efficiency is comparable to traditional folding houses.
Q5: How long is the service life of the 8.8 bolt accessories?
A: The 8.8-grade high-strength bolts are made of high-quality carbon steel with anti-rust and anti-corrosion treatment. Under normal use and routine maintenance, the bolt accessories can maintain stable performance for a long time, matching the 30-year service life of the steel frame.
Q6: Can the bolted structure support later functional renovation and expansion?
A: Yes. The detachable 8.8 bolt connection structure reserves sufficient transformation space. Users can carry out later functional adjustment, space expansion and component replacement according to project demands, with strong secondary utilization flexibility.
