We focus on the core working components of rotary drilling rigs and have built an integrated product matrix of "kelly bars - casing - drilling in tools" to meet the diverse demands of different geological conditions and construction scenarios. 

- **kelly bar Series**: Independently developed high-strength and wear-resistant drill pipes, made from high-quality alloy steel and processed with advanced heat treatment techniques, feature outstanding bending and torsional resistance. They are suitable for small to large rotary drilling rigs, balancing construction efficiency and service life.

- **Casing Series**: Produce a full range of casing types, including protective and spiral casings, precisely matching the construction requirements of complex strata. They effectively prevent hole wall collapse, enhancing the safety and stability of pile foundation construction.

- **Drilling tools Series**: Include a variety of drilltools such as rock drilling auger ,bucket ,CFA, rock and soil drill bits, and sand scoops, with optimized tool layout and structural design for different geological conditions like rock layers, clay layers, and gravel layers, significantly improving drilling efficiency and rock-breaking capacity.
