Ductile iron manhole cover
We manufacture ductile cast iron manhole covers, using static pressure line casting process. My factory has 200 workers, produces 70 tons of manhole covers every day. We have our own blast furnace, therefore,No the secondary melting molten iron water,So we can supply good price for our celient. At present, our annual production of 200000 tons pig iron by hot blast furnace, a 3 tons of electric furnace 2 sets, tensile test, pressure test, Optical Spectrum Analyzer and other testing equipment complete. D.I manhole covers are made according to BSEN124 standard. We have carried out export businesses to Turkey,Singapore, Italy, Saudi Arabia, Dubai etc.
All our achievements are realized through client caring and supporting. We will try our best to supply satisfactory services for our clients. If you have interests in our products, please check our website and feel free to contact us.
