Benefits of mountain tower construction:
1. Two fire-proof observation towers are built in the mountainous
area, and the whole mountain can be seen, standing high and far
away, eliminating the blind spots of despair and saving a lot of
manpower. 2. With fixed watch towers and indoor visits, the rangers
can protect themselves from wind and sun on the one hand, and they
can also focus on forest fires on the other. 3. The construction of
forest fire prevention observation towers will better reflect the
policy of “prevention first and active elimination”, to ensure the
safety of people’s lives and property, and to protect mountain
forest resources.
Product Advantages:
1. Small area, saving land resources;
2. The tower has light weight, convenient transportation and
installation, and short construction period;
3. The structure is scientific and reasonable, the craftsmanship is
excellent, the appearance is beautiful, safe and durable, and the
anti-corrosion time is long.
