          1. Guard against theft


          The new anti-theft lock with design is adopted. The lock and key are made of high hardness and anti embroidery brass to prevent the lock from rusting in the process of daily use and prevent the well cover from opening. The new five proof double-layer nodular cast iron well cover adopts the integrated design of well cover and well ring, and the rotary installation lock has been obtainedNational utility model patent.


          2. Anti noise


          No noise, in line with environmental protection requirements. Each set of nodular cast iron well cover of our company is processed through three procedures to make the contact surface between the well cover and the well ring zero, so that the two can match 100% seamlessly, so as to prevent noise when vehicles pass by. A new method is adopted in the design of the new five prevention well cover


          Type design concept, so that when the vehicle passes through the well cover, it does not hit the well cover, but hit the edge of the well ring, so as to prevent the overall sinking of the well cover and effectively solve the problem of "rotten edge" around the well cover in the city.


          3. Fall prevention

          承載能力強。實驗過程中球墨鑄鐵井蓋承載500KN壓力未遭受破壞,承載能力大大優于國家標準(360KN)。同時符合歐盟EN124標準要求??山浭芨鞣N重型卡車碾壓,有 效防止因井蓋墜落產生的事故。

          Strong bearing capacity. During the experiment, the bearing capacity of nodular cast iron manhole cover is 500kN, the pressure is not damaged, and the bearing capacity is much better than the national standard (360kn). At the same time, it meets the requirements of EU en124 standard. It can withstand the rolling of various heavy trucks and effectively prevent accidents caused by well cover falling.


          4. Antiskid


          The exquisite casting process makes the product lines clear, and the well cover surface has a unique anti-skid pattern to increase friction and prevent pedestrians from slipping due to rain, snow and ice.


          5. Strong weather resistance: the well cover can be used normally in the environment of - 50 ℃ ~ + 300 ℃ through scientific formula, advanced technology and perfect technical equipment.


          6. Acid and alkali resistance, corrosion resistance, wear resistance, vehicle rolling resistance and long service life.


          7. High strength: it has high compressive, bending and impact strength and toughness.


          8. Beautiful appearance: the surface pattern of the well cover is exquisitely designed and the color is bright and adjustable. The Beijing cement well cover beautifies the urban environment.


          9. Easy to use, customized cement well cover, light weight: the product weight is only about one-third of that of cast iron, which is convenient for transportation, installation and emergency repair, and greatly reduces the labor intensity.
