Precision dimensions, material metallurgy, and field logistics parameters for Model air-dome-30m-span-300m-len.
| Clear Span Width | 30m (100ft) Zero-Column Span |
| Building Length | 300m (983ft) Continuous Enclosure |
| Erection Timeline & Crew | Mobilized and deployed within 5 to 7 working days by a specialized 8-person crew. Once perimeter foundation clamps and cable harness are anchored, inflation to full structural rigidity requires only 2 to 3 hours via industrial centrifugal blowers. |
| Fire Safety Rating | DIN 4102 B1 / NFPA 701 Method 2 / EN 13501-1 |
| Corrosion Protection | ISO 1461 Hot-Dip Galvanized (≥85μm) or Architectural AA15 Anodized |
| Wind & Snow Calculation | Designed under ASCE 55-16 (Tensile Membrane Air-Supported Structures). Patented orthogonal bias-laid Ø12mm–Ø16mm aircraft steel cable net anchors directly to reinforced perimeter concrete foundation beams. Automatic variable-frequency blowers boost internal pressure from 250 Pa to 450 Pa during storm alerts, resisting up to 150 – 160 km/h typhoon gusts. |
Every Champion project is manufactured strictly from CNC-driven CAD/CAM fabrication packages. Structural nodes, chord junctions, baseplate anchor details, and membrane tensioning tracks are analyzed under finite element analysis (FEA) to confirm full compliance with international building codes.
Pre-stressed, anti-wicking, low-creep architectural textiles engineered with multi-layer PVDF/PVF lacquering for self-cleaning performance, UV shielding (UPF 50+), and permanent flame retardancy.

Rapid deployment methodology requiring zero on-site welding. Modular bolted connections reduce field erection schedules by up to 70% compared to conventional structural steel.
Laser level and total station establish precise axial centerlines, column offsets, and elevation datums across the clear-span foundation grid.
Heavy cast-in base plates, chemical anchor studs (Grade 8.8), or helical earth anchors are drilled and torqued to specified kN pullout resistance.
Space-frame chord segments, web lacing members, and connection gusset plates are assembled and bolted flat on grade prior to hoisting.
Mobile cranes elevate paired structural truss arches into vertical position; temporary stabilizing guy wires maintain plumbness and stability.
Longitudinal purlins, eaves struts, and pre-stretched galvanized X-bracing cables are torqued into place to form a rigid 3D spatial diaphragm.
High-tenacity PVDF roof panels are pulled through integrated aluminum extrusion tracks and mechanically tensioned via ratchet catenary winches.
Hard-wall panels, vertical-lifting Megadoors, motorized louvers, perimeter rainwater gutters, and architectural flashing trims are sealed.
Calibrated torque audit of all structural fasteners, ultrasonic weld verification, membrane pre-stress tensiometer inspection, and handover documentation.
Our structural engineering team provides certified calculations, foundation reactions, and full 3D CAD/BIM packages within 24 hours.
