Pre Designed Clear Span Steel Structure Frame Metal Construction Buildings Industrial

I. Definition

1. Structural System
   • Prefabricated steel structure frame (mainly H-beams/rectangular steel tubes) with metal enclosure systems
   • Includes standardized design drawings (Free Drawing) for direct construction use
2. Design Mode
   • Pre-set standard layout/span schemes (e.g., single-span/multi-span portal frames)
   • Provides free CAD/3D drawings (with structural calculation sheets and joint details)

   • 

II. Characteristics

1. Design Features
   • Modular selection: 5 standard column spans (6m/9m/12m) and 3 eave height options
   • Customizable drawings: Free modification of door/window positions and load parameters
2. Physical Properties
   • Wind resistance ≥0.55kN/m², seismic design intensity of 8 degrees
   • Hot-dip galvanized steel components (zinc layer thickness ≥220g/m²)
3. Construction Features
   • Factory prefabrication rate ≥90% (components produced with numbered labeling)
   • No on-site welding (bolt connection + self-tapping screw fixing)
   • 

III. Advantages

1. Cost Benefits
   • Free drawings (saves 10%-15% on design fees)
   • Standardized production reduces material waste rate (<3%)
   • 
2. Construction Efficiency
   • 15 days to complete 1,000㎡ main structure installation (60 days for traditional concrete structures)
   • No need for specialized construction teams (assembly by drawings)
   • 
3. Flexibility
   • Easy post-construction expansion (can add mezzanines/overhangs)
   • High space reusability (no load-bearing walls)

   • 

4. Service Benefits
   • Free construction technical guidance
   • Lifetime drawing upgrade support (adapts to code changes)

   • 

IV. Applications

1. Industrial Use
   • Machinery workshops, warehousing logistics centers
   • Automotive 4S 店 maintenance workshops
2. Commercial Use
   • Exhibition halls, sports venues
   • Large supermarkets, agricultural product markets
3. Agricultural Use
   • Large-scale farms, agricultural product processing workshops
   • Agricultural machinery warehouses, greenhouse skeletons
4. Temporary Use
   • Construction temporary offices, post-disaster resettlement housing
   • Temporary pavilions for large events
   •
