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.

Why Choose Our Steel Structures

Computational Material Stewardship & Optimization: High-fidelity structural modeling eliminates material redundancy, lowering costs while enhancing sustainability.
Automated Technical Fidelity & Precision: Digitally-controlled manufacturing ensures millimeter-level tolerances for seamless field assembly.
Holistic Project Orchestration (Turnkey Governance): Single-source partnership managing the entire structural lifecycle from design to handover.
Global Benchmark Compliance & Lifecycle Advocacy: Strict adherence to international engineering codes with lifecycle-focused support to preserve asset value.

Packing & Loading

Engineered Transit Shielding & Structural Encapsulation: Multi-layered industrial-grade protection ensures components arrive with finishes and integrity intact.
Advanced Volumetric Nesting & Matrix Optimization: Sophisticated spatial algorithms maximize container loading density, reducing shipping overhead.
Just-in-Time (JIT) Supply Chain Synchronization: Precision-timed fulfillment integrated with construction schedules to eliminate storage bottlenecks.
