In residential areas, villas, and public gardens, both security and aesthetics are required. Traditional brick walls or iron fences look heavy and lack design sense.

In mountainous roads or railways, landslides and falling rocks often occur, causing traffic congestion or accidents. Traditional retaining walls alone cannot completely solve the issue.

In border areas, airports, prisons, and military bases, a long-term and stable security system is required to prevent illegal intrusion, climbing, or sabotage. Traditional brick walls are expensive, time-consuming to build, and difficult to maintain.
