Product Description
Multi-Story High-Rise Steel Structure Public Building
As a professional structural steel manufacturer, we specialize in prefabricated multi-story steel architecture for public buildings, delivering precision-engineered solutions for urban development.
Prefabricated Multi-Story Steel Architecture
- Industrialized Construction Paradigm: We redefine urban development by shifting from unpredictable site-based labor to high-precision, factory-driven assembly, ensuring industrial-grade certainty.
- Precision Engineering & Rapid Deployment: Our controlled manufacturing ensures millimeter-level accuracy and compressed project timelines for faster occupancy.
- Spatial Fluidity & Future Agility: High-strength steel enables expansive, column-free spans that maximize leasable area and provide long-term flexibility.
Technical Specifications
| Component | Specification |
|---|---|
| Main Steel | Q355, Q235, Q355B, Q235B, etc. |
| Anti-rust Protection | Hot-dip galvanized or anti-rust painting |
| Purlin and Girts | Cold-rolled C or Z steel, Q355 or Q235 |
| Column & Beam | Welded or Hot rolled H-section |
| Connection Method | Welding connection or bolt connection |
| Wall & Roof | Sandwich panel or steel sheet |
| Door | Rolled up door or Sliding door |
| Window | Plastic steel or Aluminum alloy window |
| Surface | Hot-dip galvanized or painted |
| Crane | 5MT, 10MT, 15MT, and more |
Advanced Painting System
- Layer 1: Molecular Passivation & Reactive Priming: Foundational layer that passivates steel substrate to neutralize oxidation and create a non-porous seal against moisture.
- Layer 2: Cross-Linked Molecular Armor (High-Build Epoxy): Dense intermediate barrier providing superior adhesion and protection against industrial pollutants and corrosive climates.
- Layer 3: Atmospheric Resilience & Chromatic Shield (PU Topcoat): Premium polyurethane finish engineered for permanent color fidelity and UV resistance.
Common Applications
- Agile Corporate & Commercial Environments: Expansive column-free spans maximize net leasable area while providing structural agility for evolving workplace configurations.
- High-Velocity Urban Residential Solutions: Rapid-track deployment of high-performance residential complexes with inherent fire-resistant properties.
- Sensitive Institutional & Healthcare Infrastructure: Minimal community disruption through off-site fabrication, compressing construction schedules for vital public services.
- High-Capacity Mobility & Vertical Parking Hubs: Scalable high-load-bearing parking solutions designed for high-frequency traffic and urban congestion.
