2. Stainless steel police sentry box is made of stainless steel, which will not cause corrosion, pitting, rust or wear, and has environmental protection properties such as corrosion resistance, strength enhancement, steel deformation and cracking resistance, and rust resistance. It is suitable for some public environment hardware facilities used in harsh environment, and if the surface is painted, the adhesion strength will be higher, but the corrosion resistance will disappear after the zinc layer on the surface is damaged. It is often used in expressway toll station.
3. The structure of the composite police sentry box is made of aluminum-plastic plates, and the internal and external materials of the composite police sentry box are aluminum-plastic plates, which not only retains the main characteristics of raw materials, but also overcomes the shortcomings of raw materials, thus obtaining many excellent material properties. Product features: colorful decoration, weather resistance, corrosion resistance, impact resistance, fire prevention, moisture resistance, sound insulation, heat insulation, earthquake resistance, light weight, easy processing and molding, easy handling and installation.
