Strict official competition safety standards. As provincial multi-sport event venues, the fences must meet official competition specifications. Conventional metal or composite panels are prone to deformation under repeated ball and athlete collisions, and hard surfaces increase athlete injury risks.
Tight construction schedule for renovation. Multiple venues were under simultaneous retrofitting with overlapping cross-construction works. On-site cutting and installation must be completed rapidly to meet the pre-games acceptance deadline.
Outdoor & indoor dual-environment resistance. Some venues are semi-open; panels need strong UV resistance, moisture resistance, and color stability. Ordinary materials easily age, fade and deform under sun and humidity.
Unified visual effect & post-event reuse requirement. All venues required consistent color and appearance for the provincial games. After the event, venues will shift to public fitness, so the dasher boards need to adapt to diversified mass sports activities.
