1, With more than 20 years experience in foundation engineering field. We improved design of drilling tools for different soils conditions, such as angle of drilling bit and bucket teeth, number of teeth, thickness of bucket shell and casings, kelly pipes for kelly bar.

2, Our welding technicians has many years experience for drilling tools and machines and all the equipments are the first class brands in China. we are also using welding robots for kelly bars and drilling buckets. After years of experimentation, we carefully selected the raw materials, such as harddox 500 for kelly keys, 35Crmo for kelly pipes, 25Crmo for casing joints, 42crmo for body of drilling bit etc.

3, About 15000㎡ production base, with highly skilled and motivated team of research & development engineers. We can produce 500 pcs of bucket and auger for each month, 20 sets of kelly bars, 200m of casing tube, 50000pcs of drilling bit.

4, One year warranty for kelly bar, pile breaker, slurry desander, vibro hammer. If there is any quality problem, we will send our engineers to jobsite. And sending the new machines or tools to you right away.
