The meter box has better physical, chemical properties and mechanical strength than gas meter boxes such as plastic, metal, and hand-laid FRP. It has the functional effects of being more convenient to install and use, and more thoughtful and strict user management. The surface of the box is printed with color separation screen with good visual effects, and it also has advertising functions to beautify the community environment, warn safety, and highlight customers 'beautiful corporate image. This meter box is widely used in centralized gas management systems in urban residential areas and high-low-rise buildings. It is safe and beautiful to use.

SMC workshop, molding workshop, assembly workshop, paint workshop, sheet metal workshop, assembly workshop and injection molding workshop have been established.
Our company uses a new composite material SMC to produce gas meter and flowmeter boxes. The box produced by this material is beautiful and generous, and is currently widely used. It has been in use for nearly ten years. The newly developed SMC molded gas meter box is a sheet-like mold material mixed with more than a dozen composite materials such as unsaturated polyester resin, glass fiber, low shrinkage, calcium powder, and various additives, and formed by a forging machine at high temperature and high pressure. It has the advantages of excellent corrosion resistance, insulation, flame retardant, light weight, beautiful appearance, inability to recycle, and long service life (outdoor design service life can reach more than 40 years, indoor design service life can reach more than 60 years).
The meter box has better physical, chemical properties and mechanical strength than gas meter boxes such as plastic, metal, and hand-laid FRP. It has the functional effects of being more convenient to install and use, and more thoughtful and strict user management.
