About Us: 18 Years of Excellence in Cold Drawn & Honed Tubes

Jiangyin Carridea Technology Co., Ltd. is a professional original manufacturer and OEM supplier specializing in high-precision cold drawn tubes, honed tubes, and hydraulic cylinder tubes. Nestled in Jiangyin City, Jiangsu Province—China’s core steel processing and manufacturing hub—the company was founded in 2008 and has focused exclusively on precision steel tube production for 18 consecutive years. After nearly two decades of steady development, we have evolved from a local processing factory into a mature, standardized, and internationally trusted source manufacturer, serving stable and long-term clients across Europe, North America, Southeast Asia, the Middle East, and Oceania. Throughout our development, we have adhered to three core business tenets: ultra-high precision, consistent product quality, and reliable on-time delivery, which precisely address the core procurement demands of global hydraulic system manufacturers, mechanical equipment factories, and engineering machinery enterprises.

Our production base spans 15,000 square meters of standardized industrial workshop space, equipped with a complete set of full-process independent production lines and professional testing equipment. We realize one-stop integrated production covering raw material cutting, precision cold drawing, stress-relief heat treatment, high-precision straightening, fine honing, skiving and roller burnishing, finished product calibration, strict quality inspection, and standardized export packaging. Breaking the fragmented processing model of most small factories, our full in-house production chain effectively controls product accuracy, surface quality, production cycle, and batch stability, eliminating intermediate processing links and quality risks. As a certified national high-tech enterprise, we mainly process and produce mainstream high-performance steel grades including 27SiMn, 45#, 20#, Q345B, ST52, and E355, widely applicable to hydraulic cylinder manufacturing, construction machinery, agricultural automation equipment, industrial pressing machinery, and intelligent automation industries.

What distinguishes Carridea from ordinary steel tube suppliers is our persistent and rigorous quality management philosophy. We firmly believe that consistent and stable quality is the cornerstone of long-term global cooperative relationships. To eliminate batch differences and defective products, we have formulated more than 30 standardized quality control procedures covering the entire production process. Every batch of raw materials undergoes strict incoming inspection on chemical composition and mechanical properties; every key production link is monitored and recorded in real time; every finished product is subject to dimensional calibration, surface inspection, and non-destructive testing. All our products fully comply with international authoritative standards such as EN 10305-1, DIN 2391, and ASTM A519, ensuring every exported steel tube meets global industrial precision and durability requirements.

Eighteen years of industry focus has endowed us with profound technical accumulation and rich practical experience in professional material selection, production process optimization, and micro-precision control. We have an in-depth understanding of the common pain points of overseas importers and manufacturers in cross-border procurement: unstable dimensional tolerances, unqualified inner surface finish, inconsistent batch quality, uncontrollable delivery cycles, and inefficient after-sales response. Targeting these industry problems, we rely on advanced CNC precision equipment, a professional technical and production team, and scientific standardized management mechanisms to provide targeted solutions, helping clients reduce procurement risks, optimize production costs, and improve product competitiveness.

At Carridea, we never position ourselves as a simple product supplier, but as a reliable long-term strategic manufacturing partner for global clients. We support both standard specification bulk orders and personalized customized processing according to customer drawings and technical parameters. From early technical confirmation and process optimization to mass production, quality inspection, and door-to-door cross-border delivery, we provide full-cycle one-stop professional services. Choosing Jiangyin Carridea means choosing 18 years of professional industry precipitation, stable and reliable product quality, efficient and worry-free procurement services, and lasting trustworthy cooperative support.
