Gnee can provide professional services, such as the cutting of wear-resistant plates, high-strength plates, extra-thick plates, die steel and other kinds of steel plates, structural parts processing, transportation and distribution of the steel plates, to the factory. We not only effectively help to reduce the amount of processing in the manufacture of large-scale machinery and equipment accessories, gearboxes, rolling mill arches, bearing seats, etc., but also help the customers to save their manpower, material resources and energy from the complicated procedures of steel plate raw material procurement, commissioned processing, and transportation, etc., so that to achieve the goal of zero inventory of raw materials, reduce capital and equipment investment. About Cutting Processing: thickness range is 3～600mm, width is below 4100mm. The geometrical dimensions and specification of the cutting parts are accurate with the characteristics of "high efficiency and high precision", and the quality of the steel plates is stable and reliable.
