Innovative connections ensure reliable roof performance:
Weather-Sealed Joints:
EPDM-gasketed bolted connections in H-beams (HEB300) prevent water ingress, critical for retractable roofs. The Mercedes-Benz Stadium in Atlanta uses these to maintain a dry field during 150mm/h rain.
Dynamic Load Absorption:
Slotted connections with friction dampers allow 50mm thermal expansion/contraction in H-beams. Wembley Stadium's roof employs this design to avoid stress cracks in temperature swings from -5°C to 35°C.
Quick-Acting Mechanisms:
High-strength alloy pins in H-beam hinges enable roof retraction in 8 minutes. Singapore's National Stadium uses these connections to switch between open/closed modes for different events.
