cast iron manhole cover,
heavy duty manhole covers
High Intensity Double Sealed Recessed Manhole Cover Anti Sedimentation
High standard: strictly enforce PRC National Standard GB/T23858-2009 Manhole Cover and European Standard EN124:1994 Automotive and Pedestrian Regional Drainage Cover Plate and Manhole Cover Plate Standard.
Light: its weight is only about one third of that of cast iron, which is greatly lower than that of cement well cover, is convenient to transport and mount, and greatly relieves the labor intensity.
High intensity: by using BMC composite well cover produced by BMC in combination with steel reinforcement framework at high temperature and high pressure, the highest test load can reach F400KN; by using high-intensity SMC composite well cover produced by HZ-SMC sheet molding compound, the highest test load can reach F900KN.
Appearance: manhole cover has beautifully designed surface pattern, which can be individually designed according to user requirements and be made in various colors, to beautify urban environment.
Antitheft: this synthetic material is unrecyclable, and can guard against thefts naturally; it is equipped with a locking structure, to prevent burglary of downhole properties.
Weather resistance: the product is produced by taking high polymer materials with high molecular weight and strong chemical stability as raw materials, and can be normally used at -50.0-―+150.0 by virtue of scientific formula, advanced process and perfect technical equipment.
High accuracy: this product is subjected to high-temperature compression molding, and has small cover frame clearance, thus overcoming the defects of “running, jumping, sounding” of well covers made of cast iron, cement, etc., and improving the highway capacity and driving comfort.
Corrosion resistance: passing the inspection of National Chemical Building Material Test Center, the product features corrosion resistance, acid and alkali resistance, 3-level anti-ageing index or higher, and longer service life. Good after-sales service: strictly enforce the warranty policy on the premise of non-artificial damages and correct use of the product.
