Procurement Summary
Technical points buyers normally confirm first.
Use this page as a starting point for RFQ discussion. Exact chemistry, mechanical properties, delivery condition, testing, and certificate requirements should be confirmed against the active order standard.
Delivery and surface routes
- Hot rolled
- Normalized
- Peeled
- Cut-to-length
Inspection discussion
- Chemical composition verification
- Dimensional inspection
- Mechanical testing upon request
What buyers should confirm
- Equivalent standard and active order specification
- Diameter, length, tolerance, and quantity
- Delivery condition and surface route
- Processing needs such as cutting, peeling, grinding, threading, or machining preparation
- Testing, certificate, traceability, packing, and destination requirements
Application Fit
Typical application routes.
Confirm grade, delivery condition, surface route, testing requirements, and downstream process before final quote.
Confirm grade, delivery condition, surface route, testing requirements, and downstream process before final quote.
Confirm grade, delivery condition, surface route, testing requirements, and downstream process before final quote.
Private Factory Processing
Processing support can be matched to the order route.
Processed through JOTAIN's private factories when project requirements call for heat treatment, peeling, grinding, straightening, chrome plating or cut-to-length preparation.
Factory capability
Review JOTAIN's heat-treatment and bright-bar processing factories before confirming delivery condition, surface route, inspection, and packing requirements.
Processing & RFQ
Connect grade choice with the required supply route.
Before quotation, confirm the processing route and document package together with the grade. This helps avoid quoting a bar that matches the grade name but not the downstream manufacturing need.
Discuss QT, normalized, or annealed route when the application requires controlled condition.
Review surface and dimensional expectations before machining or assembly.
State MTC, testing, traceability, and third-party inspection needs during RFQ review.
