• No cycle-life or vehicle-load claim is made without project test evidence

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

Huaneng can review custom hot rolling, cutting and project-specific secondary processing. Tooling, sampling, inspection frequency and production quantity are agreed after drawing review.
