Taigu ductile iron manhole cover in the course will inevitably rust, Taigu Chang in foundry to introduce you to a method for rust: projectile rust: shot blasting machine is to use a high-speed impeller blades rotate, the abrasive dispersion fired ductile iron covers the surface, abrasive high-speed flying, impact and friction surfaces of manhole covers, ductile iron covers the surface to remove rust and oxide and other ductile covers manufacturer, this method of high efficiency, good quality rust, but also make ductile cast iron covers the surface roughness in order to facilitate access to certain paint adhesion, low labor intensity, dyed lighter hollow of a tree on the environment, production plant should give priority to the use of such methods. Gu Chang-year foundry founded in 2006, is a new modern and dynamic enterprises. Since the construction of ongoing efforts to grow, is to become a professional production of ductile iron covers the company, with annual production capacity of 5,000 tons, is being expanded with an annual output of 10,000 tons. I would like to plant good quality, competitive price ductile covers, on time delivery for the majority of merchants to provide high-quality service. When selecting the cast iron cover what should be the basis? Load capacity is based, broadly divided into the following three: First, the light: 25 t / m2; car, pedestrians campus residential park, park cable trench cover, underground parking and other kitchen. Second, heavy: 70 t / m2; 20 tons of plant automobile traffic, road gutter cover general atlas, roadside roads, parking lots and streets. Third, the super-heavy: 140 t / m2; heavy trailer, container forklifts, cranes and aircraft traffic trunk road ductile covers companies, large car parks, mines, docks and airports. Shanxi Taigu County Chang foundry is located in the hometown Inoue - Kim Gu treasure. Taigu Shanxi Jinzhong City, State Road 108, Hu Village Industrial Park malleable ductile covers factory where the good, the east too fast, convenient North Tongyu Qi-speed transportation and accessible. Ductile covers manufacturers, Xinjiang ductile covers, Chang-year foundry provided by Gu Chang in foundry. Gu Chang-year foundry (www.sxcnzz.com) strong, credible, in Jinzhong machining industry has accumulated a large number of loyal customers.
