WenlingStainless Steel Grass Puddle Manhole Cover
Product Description
Manhole covers, as a seemingly minor yet integral element of the urban landscape, are ubiquitous in parks and green spaces, playing a meaningful role in showcasing a city’s charm and promoting its civic culture. Yet for many years these public infrastructure components have been largely overlooked, resulting in a uniformly bland and uninspired appearance across cities nationwide. For too long, manhole covers have appeared in urban parks and green areas as little more than dark, inconspicuous “patches,” disrupting the harmonious aesthetic of the cityscape and clashing with the modern urban ethos. As a result, the design and integration of manhole covers have failed to evolve and flourish.
Stainless Steel Grass Puddle Manhole Cover
Leveraging years of mature production processes, professional production lines, and well-equipped supporting facilities, Fujian Yete Industry Co., Ltd. has specially developed a new type of manhole cover—the “stainless steel grass-pot manhole cover”—by capitalizing on the advantages of various manhole covers currently available on the market. It is also known as the “planting manhole cover,” “grass-growing manhole cover,” and stainless steel invisible manhole cover. This innovative product combines the concealed, aesthetically pleasing, and anti-theft features of resin grass-pot manhole covers with the robustness and durability of stainless steel manhole covers. Utilizing a completely new design concept, it is formed in one stamping operation using 2mm 304 stainless steel, eliminating the need for welding. From production to installation, there is zero material loss, resulting in a longer service life, energy efficiency, environmental protection, superior resistance to compression and impact, and easy installation—making it the optimal choice for municipal construction and urban greening projects. Note: The stainless steel grass-pot manhole cover developed and manufactured by Fujian Yete Industry Co., Ltd. holds a patent certificate certified by the State Intellectual Property Office; counterfeiting will be prosecuted.
Comparison of the Advantages and Disadvantages of Industrial-Grade Stainless Steel Grass-Pit Manhole Covers vs. Traditional Grass-Pit Manhole Covers:
| Project | Stainless Steel Grass Puddle Manhole Cover | Traditional grass-pit manhole cover | Comparative Explanation | |
| Physics Performance | Material | 304 stainless steel | Resin/Plastic | |
| Tensile strength (N/mm²) | ≥530 | ≥49 | Plastic accounts for 9.2% of stainless steel. | |
| Wear resistance | High | Low | Severe erosion due to water flow | |
| Ultraviolet irradiation | No aging issues | Severe aging | Plastics degrade severely under light. | |
| Coefficient of thermal expansion (10-6/ ℃) (0~100 ℃) |
17.3 | 70 | Plastic is four times that of stainless steel. Plastics generally exhibit thermal deformation; with a temperature difference of 40°C, they expand by 6 centimeters per 10 meters. |
|
| Cold Adaptation | ≤-270°C |
Must be ≥0°C
Otherwise, there will be a change in brittleness.
|
Plastics are not suitable for low-temperature environments and become brittle in winter. | |
| Heat Adaptation | ≥400°C | Should be ≤50°C Leaching of hazardous substances |
Plastics are not heat-resistant.
Toxic gases are produced during combustion.
|
|
| Corrosion-resistant | Excellent | Weak | ||
| Safety and Environmental Protection | Aesthetics | Beautiful and exquisite appearance | Common | Stainless steel is more suitable for landscape design. |
| Impurity aggregation | Not easy | Easy | Stainless steel cleaning, high glossiness | |
| Security |
High |
Low |
Traditional manhole covers are prone to weathering and cracking, posing safety risks. |
|
| Environmental performance | 100% recycled | Non-degradable, non-reusable | Plastic grass pot manhole covers are not green materials. | |
| Service Life (years) | More than 30 years | Weathering and fragmentation in two to three years | Plastic is less than 1/20 the weight of stainless steel. | |
