Precast sentry box is a common building type, which is widely used in the safety and management of public places.
There are generally two kinds of materials for prefabricated sentry boxes: one is steel structure sentry box, and the other is concrete sentry box. The steel structure sentry box is mainly made of stainless steel or galvanized steel plate, which has the characteristics of corrosion resistance and durability, strong craftsmanship and high construction efficiency. Concrete sentry box has strong stability and earthquake resistance, and its reliability is better used in the construction of permanent sentry box.
Anti-corrosion treatment of prefabricated sentry box mainly adopts two methods: surface spraying and hot dip galvanizing. The surface spraying method is to spray anti-corrosion paint evenly on the outer surface of the sentry box, which has the advantages of low cost, simple construction and obvious anti-corrosion effect. Hot-dip galvanizing treatment is to form a zinc layer after pickling, drying and dipping the booth parts, which has strong corrosion resistance and can effectively prolong the service life of the booth.
To sum up, the material and anti-corrosion treatment of prefabricated sentry box are important factors affecting its service life and stability. In the process of design and construction of the sentry box, appropriate materials and anti-corrosion treatment methods should be selected according to specific conditions, and regular maintenance should be carried out during use to prolong its service life and ensure work safety and management benefits.
