Stainless steel manhole covers are the type of manhole covers widely used in urban infrastructure. With their excellent performance and aesthetics, they have gradually become a substitute for traditional cast iron manhole covers. The following is a detailed description of stainless steel manhole covers:

 Materials and Structures

1. Material
-Usually 304,201 stainless steel or 316 stainless steel, with high strength, corrosion resistance, high temperature resistance and other characteristics.
-316 stainless steel containing molybdenum elements, corrosion resistance is stronger, suitable for coastal, chemical and other corrosive environment.

2. Structural design
-It is divided into invisible manhole covers (surface can be paved with floor tiles, asphalt, etc.) and traditional manhole covers (exposed).
-Reinforced skeleton or composite material can be installed inside to enhance load-bearing capacity.
-Various shapes: round, square, rectangular, adapt to different scene needs.

Core advantages

1. Strong corrosion resistance
-Stainless steel surface to form a dense oxide film, against acid rain, salt spray, chemical corrosion, life of up to 20
2. Beautiful and practical
-Invisible manhole covers can be integrated into the surrounding environment (such as squares, pedestrian streets) to keep the ground level and beautiful.
-The surface can be customized pattern or logo to meet individual needs.

3. Excellent load-bearing performance
-According to the requirements of the design of load-bearing class (such as light, heavy,), the maximum can carry more than 20 tons.

Application Scenarios

-Municipal works: roads, drainage systems, power communication wells, etc.
-Commercial area: pedestrian street, square, park and other landscape areas.
-Industrial areas: corrosive environments such as chemical plants, ports and airports.
-Residential area: community green belt, parking lot, etc.

Installation and maintenance

1. Installation points
-A well head of appropriate size shall be reserved to ensure that the cover matches the frame.
-Invisible manhole covers shall be matched with concrete base to ensure stability.
Size can be customized according to the needs of the site regular size 500 x 500、600 × 600、700 × 700、800 × 800, etc.
