With the country increasing investment in infrastructure and the development of urbanization, the national investment in public facilities is very large. It is estimated that the country adds at least 10 million new manhole covers and replaces another 10 million every year, showing the huge demand for manhole covers. The "urban traps" formed by missing manhole covers have become a social problem that concerns the public, troubles the government and distresses the victims. People urgently hope for a good solution.

Whether in large cities, small and medium-sized cities, or economically developed towns, as long as there are public facilities such as tap water, street lights, drainage, telecommunications, gas, heating, fire protection and sanitation, inspection wells need to be installed. Generally, a city with a population of 500,000 can have 250,000 rainwater grates and manhole covers in stock, with an annual demand of about 20,000 to 30,000 covers. In addition, because cast iron manhole covers have recycling value, some lawbreakers steal and smash cast iron manhole covers and sell them to scrap recycling shops. Stainless steel decorative manhole covers just meet the condition of not being easily stolen, so more municipal construction projects have begun to choose Chengdu stainless steel decorative manhole covers.

Classification of stainless steel decorative manhole covers: By standard: light covers, heavy covers and standard covers. By material: stainless steel decorative manhole covers are divided into grade 201, 304, 316 and galvanized covers.

Advantages of stainless steel decorative manhole covers: Anti-theft: compared with covers of other materials, stainless steel decorative manhole covers are stronger, with tight and small joint gaps, so ordinary tools cannot easily pry them open. Safety: the cover must not only prevent theft, but also take responsibility for the safety of pipeline construction workers. Because steel bar supports are used, the stainless steel decorative manhole cover will not shatter even under destructive load, preventing the hazards of falling. High precision: stainless steel decorative manhole covers use compression molding, with small gaps between the cover and the seat, overcoming the old problems of "running, jumping and rattling" of traditional manhole covers.
