LF Steel Structure Dome Design Building Space Frame Dome Glass Hall Prefab

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support & Design: A steel frame dome engineered with radial beams for load-bearing capacity, enabling large open spaces with transparent or translucent roofing (e.g., glass). The welded steel structure ensures durability and stability for roofing applications.
  • Material Versatility: Constructed from high-grade steel (Q235, Q345, Q355) for strength and corrosion resistance, with hot-dip galvanization enhancing longevity. Customizable to integrate glass or other materials for aesthetic and functional needs.

Key features

  • 1. Corrosion-Resistant Hot-Dip Galvanized Steel

    • With hot-dip galvanized steel and high-grade Q345/Q355 steel, you can ensure long-lasting durability and corrosion resistance in harsh outdoor environments. This treatment provides 2x longer lifespan than non-galvanized steel structures*.

  • 2. Radial Beam Architecture for Structural Efficiency

    • With a radial beam design and welded steel frames, you can achieve a structurally sound dome that evenly distributes loads, offering 30% higher wind resistance than traditional dome frameworks*.

  • 3. High-Strength Steel for Heavy Load Capacity

    • With Q345/Q355 steel grades, you can support up to 50% heavier loads compared to standard steel domes*, making it ideal for commercial applications like atriums or industrial roofing.

  • 4. Modular Prefab Design for Scalable Installation

    • Designed for large-scale commercial spaces, this dome provides quick assembly and customizable sizing, enabling 50% faster installation than site-built alternatives*.

  • 5. GB Compliance for Safety and Quality Assurance

    • With GB certification, you can meet national building standards and ensure structural integrity, unlike uncertified competitors*.

Supplier's note

  1. Technical Breakthroughs:

    • Q355 Steel: The Pro Model’s Q355 grade offers 35% higher tensile strength than Q235, enabling use in seismic zones or high-wind regions.
    • Radial Beam Geometry: The symmetrical design reduces material waste by 20% compared to traditional domes while maintaining structural rigidity.
    • Hot-Dip Galvanization: Provides 2x longer corrosion resistance than untreated steel, ideal for coastal or industrial environments.

  2. Version Selection Guide:

    • Base Model: Suitable for standard residential or low-load commercial spaces (e.g., small atriums).
    • Advanced Model: Recommended for mid-sized venues requiring UV-protected glass or moderate customization (e.g., hotels, schools).
    • Pro Model: Optimal for heavy-duty applications (e.g., industrial warehouses, sports complexes) needing extreme durability and bespoke aesthetics.

Example Use Case: With the Pro Model’s Q355 steel and premium galvanization, you can construct a dome for a coastal resort that withstands saltwater corrosion while integrating LED-lit oculus designs for nighttime ambiance.
