    I had the lights turned on (except for testing purposes yet), but they are a nice size and seem to be pretty bright. I have been looking for battery operated lights for my projects and these seem like they will work nicely as they are individual so you can use as few or as many as you want -

Product Description
AirBrother 30×50m Air-Supported Membrane Building – 1,500m² Modular Dome Solution
Solution Overview

The AirBrother 30×50m Air-Supported Membrane Building is a high-safety, modular, fast-delivery large-span structure designed for multi-functional indoor use. Operating on a continuous internal positive pressure system (200–300Pa), this column-free architectural solution eliminates the need for traditional steel pillars, creating a bright, open, and highly flexible interior space.

Engineered for both temporary and semi-permanent operations, it is the premier choice for sports arenas, indoor RC racing tracks, exhibition halls, and event venues.

Core Dimensional Specifications
ItemConfiguration
Building SizeWidth 30m × Length 50m
Total CoverageApprox. 1,500 m²
Side Clear Height≥ 4.5m (Customizable)
Center Peak HeightRecommended 9.0m – 12.0m
Modular Assembly4–5 Modules (Each ~10m – 12.5m long)
Main Entrance OpeningWidth 4.5m – 5.0m × Height 4.2m – 4.5m
Technical Parameters & Materials

The dome utilizes high-grade architectural membrane materials, ensuring longevity and safety across extreme climates.

  • Membrane Material: Double-sided PVC-coated polyester fabric (Recommended 850–1100 g/m², thickness ~0.70–0.90mm)
  • Target Service Life: ≥ 8–10 years
  • Operating Temperature: -20°C to +60°C
  • Flame-Retardant Rating: Meets EN 13501-1 B-s1,d0 / B-s2,d0 or GB 8624 B1 (B1级)
  • Wind Resistance: Designed for operating wind speeds ≥ 28 m/s
  • Snow Load Capacity: Roof snow load ≥ 0.50 kN/m² (with snow-pressure increase strategy)
Structural & Operational Systems
Positive-Pressure Support System

Continuous fan-driven air supply maintains stable internal pressure. The system includes automatic pressure control, high-wind/snow mode adjustments, maximum safe pressure limits, overpressure relief devices, and low-pressure alarms.

N+1 Redundant Fan System

To guarantee 100% operational safety, the system employs an N+1 redundant fan configuration. If any primary fan fails, backup units seamlessly maintain required pressure while triggering an automatic alarm.

Power Failure Emergency Protection

Integrated with a comprehensive emergency plan including backup power supply / generator interface, UPS for control power, and audible/visual alarms with clear personnel evacuation protocols.

Pressure-Retention Entrance Design

To prevent rapid pressure loss during entry, the main entrance utilizes advanced airlocks including air-lock lobby, revolving doors, high-speed rolling doors, or double-door systems.

Functional Configuration & Customization
Lighting & Hanging Interfaces

Reliable webbing and hanging points support lightweight equipment with single-point load capacity ≥ 25 kg. Applications include LED lighting systems, HVAC ducts, cable management, and display installations.

Daylighting System

Exterior membrane in industrial white or light gray balances natural lighting with heat reflection. Optional transparent or translucent daylighting strips can be integrated for enhanced illumination.

HVAC & Fresh Air Interfaces

Reserved interfaces (DN500–DN800 round, or 600×600mm / 800×800mm rectangular) with reinforced flanges and rainproof structures for easy connection to environmental control systems.

Emergency Exits

Minimum of 4 personnel/emergency exits recommended, optimized for local fire evacuation and safety requirements.

Anchoring, Drainage & Condensation Control
  • Anchoring System: Continuous foundation/ground beam systems with clamping grooves and anchoring rails—strictly excluding temporary sandbags as the main method
  • Drainage System: Continuous perimeter drainage channels with drainage points set every 10–15 meters
  • Condensation Control: Supports double-layer membranes, thermal insulation liners, mechanical ventilation, and anti-dripping designs for moisture prevention
Compliance & Deliverables

AirBrother ensures full compliance with international structural standards (EN 13782, EN 1991-1-4/1-3) and Chinese standards (CECS 158, T/CECS 1323, GB 50009, GB 55001).

Standard Supplier Deliverables Include:
  • Design Documents: Floor plans, section drawings, module division plans, and anchoring layouts
  • Technical Documents: Material data sheets, flame-retardant test reports, structural calculation summaries, and wind/snow load descriptions
  • Quotation Documents: Itemized pricing for membrane modules, doors, fan/control systems, packaging, and optional extras
  • Logistics Data: Packaging sizes, total gross weight, CBM volume, and container compatibility
Key Customer Value & Positioning
Maximum Space Efficiency

1,500m² of 100% column-free space for flexible interior layouts

Rapid Delivery

Modular prefabrication allows for significantly shortened construction periods

Superior Safety & Climate Adaptation

Dedicated solutions for extreme winds, snow, rain, and temperature fluctuations

Low Maintenance & Expandability

Modular design allows easy partial maintenance with pre-reserved interfaces for future expansion

Ideal For: High-safety, large-span indoor venues requiring flexible space, including badminton/basketball courts, RC racing stadiums, exhibitions, and multi-purpose community centers.
Next-Step Confirmation

To finalize the tailored proposal, customers are advised to confirm:

  1. Intended usage scenario and functional zoning
  2. Final requirements for side and center height
  3. Local maximum wind/snow load standards
  4. Need for year-round HVAC, dehumidification, or heating systems
  5. Fire evacuation approval regulations and target budget ranges
