Characteristic
Belong to a kind of high carbon chromium bearing steel which most widely used with a good performance and less alloy content. High hardenability and good comprehensive performance.Good machinability after spheroidizing annealing.High hardness,uniform organization, good wear resistance,high contact fatigue performance after quenching and tempering.And good hot working performance.
Main application:
For making all kinds of bearing ring and rolling element.For example:steel ball roller and ferrule of  internal combustion engine, electric motorcycle, automonilrd, tractors,machine tools, rolling mill, boring machine, mining machinery, general machinery,high load and high speed roating mechanical transmission bearing.Except ball bearing and bearing ring, sometimes also ued to make tools, such as punching die,measuring tool.

1. HDPE Geocell
HDPE Geocell is a new type of high-strength geosynthetics, which is popular in domestic and abroad. It is a kind of three-dimensional network structure shaped by high-strength HDPE sheets through ultrasonic welding of high strength. Currently, it is being widely used in construction, such as highway, railway, bridge, dyke, etc.
Features
1. With a retractable, telescoping transport available, the construction can be tensioned into a network, fill dirt, gravel, concrete and other loose material, the structure constitutes a powerful and large lateral stiffness limit.
2. Light weight, abrasion resistance, chemical stability, light oxidative aging, acid, suitable for different soil and desert soil conditions.
3. High lateral limits and non-slip, anti-deformation, effectively enhance the dispersion of load carrying capacity and subgrade.
4. Changing Geocell height, distance, etc. weld geometry can meet different project needs.
5, flexibility, transport small; easy to join, construction speed.

2. Geogrid
Description of Geogrid
1. reinforce the base, efficiently allot and diffuse the pressure, prolong the using time;2. increase the load-bearing capabilities;3. avoid the base becoming deformed and creaking (for the material washed away);4. improve the endure, reduce the pressure of the blocking wall, save the cost, prolong the using time, and reduce the servicing;5. reduce the crook and track,6. be applicable of all kinds of soil
Application of Plastic Geogrid
1. Road surface reinforcement of road, railway and airport road;
2. Maintenance, reconstruction and widening of the old road surface;
3. Reinforcement of soil roadbed, irrigation channels and water dams.

3. Geo mattress
Made from PP (polypropylene) or PET (polyester) high strength filament Woven Geotextile. The FP geo mattress, the water flows through the filter point will be down two pieces of fabric together. It cannot let pump liquid into filter point, for the elimination of slope seepage, eliminate the pore water pressure. This type of FP geo-mattress filling mortar, which can be widely used in the underground water level. It is high and the permafrost area, play a protective role in dam.

Plastic vertical drain is like a cross parallel strips made of polyethylene and polypropylene as core board and wrapped by non-oven fabric as filter layer. Core board is to play a supportive role and drain the leaking water and air out of ground. 
Plastic vertical drain is inserted into soft soil foundation by drilling machine, under the upper part of the prepressure loading, The pore water in soft soil will be drained out through plastic vertical drain to the horizontal drainage system, and drain outward to accelerate the soft ground consolidation.
