Hydraulic rods
Straightness, machining allowance and a surface prepared for the next finishing operation.
Alloy steel processing.From gradeto delivery.
JOTAIN supplies alloy steel bars and operates its own heat-treatment and bar-finishing lines. We also coordinate inspection and quality documentation, followed by export delivery.
Material → processing → inspection → deliveryOne defined route for repeat orders.
What JOTAIN does
JOTAIN operates downstream processing. Each order follows a defined route to delivery.
JOTAIN’s industrial-steel roots date to 1999. The operating company was incorporated in Hangzhou, China, in 2004. The names listed below show how its current and historical company names relate.
Customers who previously knew us as Huatong Materials or Hangzhou Jiutian Materials can now find us under JOTAIN Materials, our current international brand. Our official website is jotainmaterials.com.

How we evolved
From steel supply to processing-led international delivery.
Industrial-steel roots
The business began with industrial steel supply and long-term relationships across China’s steel industry.
Company incorporated in Hangzhou
Hangzhou Jiutian Materials Co., Ltd. was incorporated in Hangzhou, establishing the company behind JOTAIN Materials.
AEO trade-compliance recognition
China Customs AEO General Certified Enterprise status strengthened the governance and compliance framework supporting international trade.
- Today
A more direct international route
Industrial buyers work directly with the team responsible for material, processing, inspection and shipment.
How we define supply
We plan material and processing requirements around the application.
We review the application, then agree the delivery condition, processing steps, inspection requirements and shipping arrangements.
- 01GradeA starting point
- 02Supplied conditionWhat arrives
- 03ProcessingWhat must change
- 04InspectionWhat must be shown
- 05DeliveryWhat must repeat
Shafts and pins
Toughness, fatigue exposure, heat treatment and the agreed ultrasonic-inspection basis.
Grinding rods
Stable kg/t consumption, breakage, bending and hardness response through the useful diameter.
How we work
How we plan and document supply
Application and material requirements
We review the component and operating conditions alongside the grade, delivery condition and inspection requirements.
Responsibilities at each stage
Material, processing, inspection, documents and delivery should remain connected as an order moves between organisations.
Certificates and inspection records
Original material certificates, lot identity and agreed inspection results matter more than generic quality statements.
Requirements for repeat orders
For repeat orders, we use the agreed material, processing and inspection requirements as the basis for consistent supply.
Who is responsible
Every order identifies who produces, processes, certifies and ships.
Jotain Materials Co., Ltd. co-owns two mill-linked production joint ventures with major special-steel producers. JOTAIN manages the ventures and operates its own downstream processing route. Each order identifies the applicable producer, processing route, certificate holder and delivery scope.
Manufacturing relationships
Responsibility is identified for each project.
- Where the material is produced
- Which processes JOTAIN operates directly and which follow confirmed partner routes
- Which legal entity holds the relevant credential
- Which records support the product
- How the order is marked, packed and delivered
Equity transparency
- Two separate mill-linked production joint ventures
- Jotain Materials Co., Ltd. holds equity interests of 45% and 49.5%, respectively. Both ventures are managed by JOTAIN.
- Jiangsu Huaigang New Material Technology Co., Ltd.
- Jotain Materials Co., Ltd. holds a 49.5% equity interest. The venture is co-owned with the Huaigang steel-producer partner and managed by JOTAIN.
Credentials with clear scope
Governance, systems and product evidence serve different purposes.
- Company and export governance
- China Customs AEO杭州玖田物资有限公司 (Hangzhou Jiutian Materials Co., Ltd.) and its international-trade route.
