Key Advantages
- Prefabricated 2-5 storey steel office buildings for enterprise headquarters, industrial park independent offices and factory supporting office spaces
- Main frame adopts high-strength Q355B H-beams matched with composite floor slabs to stably bear multi-layer office live loads
- Large-area glass curtain walls and thermal-insulated aluminum windows deliver high daylighting rate and bright, comfortable working environment
- Bolt-connected modular structure eliminates massive on-site welding and greatly shortens the whole construction cycle
- We provide one-stop full-chain services covering design, production and overseas installation guidance
The structural system achieves Grade 8 seismic resistance, ideal for regions prone to earthquakes. Surface shot blasting treatment together with multi-coat anti-corrosion paint extends the service lifespan. Beam dimensions are reasonably designed to secure ample clear height on every floor. We deliver complete one-stop services covering design, manufacturing and overseas erection guidance. Our engineers can coordinate with local surveyors to facilitate project acceptance procedures.
Primary Applications
- Industrial: Logistics warehouses and manufacturing plants
- Commercial: Shopping malls and automobile showrooms
- Agricultural: Large-span poultry houses and grain storage
Frequently Asked Questions
How long does it take to deliver a steel structure building?
Generally, the production cycle is 30-45 days after the design is finalized. Shipping time depends on the destination port, typically ranging from 15 to 40 days.
Can your steel buildings be customized to specific local building codes?
Yes, our engineering team can design the structure to meet specific local wind speeds, snow loads, and seismic requirements according to international standards.
What maintenance is required for a steel structure?
Steel buildings require very low maintenance. Periodic inspections of the paint or galvanized coating and clearing of roof gutters are usually sufficient to ensure a lifespan of over 50 years.
