- Cut length and downstream processing
- Trial quantity, annual demand and destination
Commercial terms, tooling, MOQ and lead time are confirmed after drawing review.
Technical overview
Product Details
This custom hot-rolled steel profile is developed for automotive door hinge components. The section is reviewed against the hinge geometry, joining method, movement interface and vehicle programme requirements rather than supplied as a universal standard part.
Typical Applications
- Side-door hinge profile blanks
- Tailgate and rear-door hinge components
- Commercial-vehicle hinge assemblies
- Custom vehicle body connection components
Reference Profile Information
The following catalogue references help identify the profile family. Final dimensions and fit must be checked against the customer drawing.
- Catalogue material examples include Q355B, Q355D and ST52-3
- Cut length, section geometry and processing are confirmed against the drawing
Engineering Review
Huaneng reviews the section geometry, steel grade, critical dimensions, tolerances and end-use requirements before confirming the manufacturing route.
- Cross-section drawing and critical dimensions
- Material grade and applicable standard
- Straightness, flatness and surface requirements
- Cut length and downstream processing
- Trial quantity, annual demand and delivery destination
Manufacturing and Supply Scope
The available scope can include profile development, hot rolling, cutting and project-specific downstream processing. Material, tooling and inspection requirements are confirmed during quotation.
Quality Documentation
Inspection items and documentation are agreed for each project. Buyers should state any required material certificate, dimensional report, mechanical-property test or third-party inspection when requesting a quotation.
Request a Feasibility Review
Send the drawing, required steel grade, tolerance, quantity and destination. Commercial terms, tooling, minimum order quantity and lead time are confirmed after technical review.
