DatongStainless steel manhole cover
Product Description
Characteristics of stainless steel manhole covers:
1. Anti-theft performance: Compared with manhole covers made from other materials, stainless steel manhole covers are more robust, feature tighter joints, and are difficult to pry open with ordinary tools, thereby offering superior anti-theft protection.
2. Safety: Manhole covers must not only prevent theft but also ensure the safety of pipeline construction personnel. Thanks to the use of reinforced steel supports, stainless-steel manhole covers remain intact even under destructive loads, thereby preventing falls and the resulting hazards.
3. High precision: The stainless steel manhole cover is manufactured using compression molding, resulting in minimal gaps at the joint between the cover and the frame. This effectively eliminates the “running, jumping, and rattling” issues associated with conventional manhole covers, significantly enhancing road traffic performance and driving comfort.
4. Convenience and Aesthetics: Stainless steel manhole covers weigh only two-thirds as much as their cast-iron counterparts, greatly facilitating installation and inspection. Invisible manhole covers are also available, ensuring that the overall aesthetic of the environment remains unimpaired; moreover, they can be color-coded according to industry-specific categories, thereby simplifying classification and management.
5. Corrosion Resistance: Manhole covers are exposed to the elements year-round, placing high demands on corrosion resistance. Stainless steel manhole covers not only exhibit excellent moisture resistance and acid–alkali resistance but also resist aging, ensuring a long service life.
Load classification for stainless steel manhole covers:
1. Light-duty: Green-space alleys, service roads, or sidewalks where motor vehicle access is prohibited.
2. Standard type: roads or parking lots with wind speeds of Level 10 or below.
3. Heavy-duty: Roads or parking lots open to motor vehicle traffic.
4. Extra-heavy: main arterial roads for motor vehicles.
Installation Steps and Precautions for Stainless Steel Manhole Covers:
1. The clear bore diameter of the wellbore shall not exceed the clear opening of the well frame to prevent the well frame from being unsupported and suspended, which could lead to accidents.
2. The relative height difference between the product’s surface and the surrounding ground shall be within the range of +2 to -2 mm; exceeding this tolerance will adversely affect the future service life and performance of the manhole cover.
3. During installation and operation, the manhole cover must always be oriented with the front side facing upward.
4. The edge of the manhole cover can be secured by pressing it down with stone or by pouring concrete to ensure the cover remains firmly in place and does not shift.
5. During on-site construction, our company can provide technical guidance and equipment.
