Steel Structure:Frequently Asked Questions by Customers

Q1: How to prevent fire in steel structure buildings?

A: Use intumescent fire retardant coating (2-hour fire resistance limit) + fireproof board cladding system, which complies with international fire protection regulations.

Q2: How to prevent corrosion in humid areas?

A: Hot-dip galvanizing treatment (zinc layer ≥ 275g/㎡) + regular maintenance to ensure more than 30 years of anti-corrosion effect.

Q3: Can it be expanded later?

A: Modular design supports rapid addition of floors/expansion, and the renovation cost is 65% lower than that of concrete buildings.

Q4: Are steel structure buildings safe in earthquake-prone areas?

A: Steel structure has high strength and good ductility, and can effectively absorb earthquake energy. Through reasonable seismic design and connection node treatment, steel structure buildings perform well in earthquake-prone areas and meet seismic code requirements.

Q5: How is the sound insulation effect of steel structure?

A: The sound insulation performance of steel structure itself is weak, but by filling sound insulation materials (such as glass wool, rock wool) and adopting double-layer wall design, the sound insulation effect can reach or even exceed that of traditional concrete buildings.

Q6: What is the thermal insulation performance of steel structure buildings?   

A: Steel structure buildings can use high-efficiency thermal insulation materials (such as polyurethane foam, extruded board) and composite wall systems, with excellent thermal insulation performance and meet energy-saving building standards.

Q7: Is the construction period of steel structure buildings long?    

A: Steel structure adopts factory prefabrication and on-site assembly, with fast construction speed, which shortens the construction period by about 40%-50% compared with traditional concrete buildings.

Q8: Is the appearance design of steel structure buildings limited?   

A: Steel structure has extremely high design flexibility, which can easily realize complex designs such as large span and special-shaped structures to meet diverse building appearance requirements.

Q9: How long is the service life of steel structure buildings?     

A: Through reasonable anti-corrosion, fire prevention and regular maintenance, the service life of steel structure buildings can reach more than 50 years, or even longer.

Q10: Is the cost of steel structure building very high?

A: Although the initial material cost is high, the full life cycle cost of steel structure building is usually lower than that of traditional buildings due to the fast construction speed, low maintenance cost and long service life.

Q11: Is steel structure building environmentally friendly?

A: Steel structure can be 100% recycled, and less construction waste is generated during the construction process. It meets the green building standards and is an environmentally friendly building form.

Q12: Is steel structure building safe in high temperature environment?

A: The strength of steel structure will decrease at high temperature, but through protective measures such as fire retardant coatings and fireproof boards, its fire resistance can be effectively improved to ensure safety.

Q13: Is steel structure building suitable for high-rise buildings?

A: Steel structure has high strength and light weight, which is very suitable for high-rise buildings. Many super high-rise landmark buildings use steel structure system.

Q14: Is the maintenance cost of steel structure building high?

A: The maintenance cost of steel structure buildings is low, mainly focusing on regular inspection and repair of anti-corrosion and fire-proof coatings, which is much lower than the maintenance cost of concrete buildings.

Q15: Are steel structure buildings prone to rust?

A: Through hot-dip galvanizing, spraying anti-corrosion coatings and other treatments, steel structures have good anti-rust properties. In a humid environment, only regular maintenance is needed to avoid rust problems.
