Which dimensions are needed to order ducts?
Internal diameter or flat cross-section, wall thickness, length, quantity and joints. Ask the technical team about B3, B4 and B5 dimensions using your drawings.
How are ducts matched to anchors?
Use the same drawing version to review strand arrangement, clearance, cross-section and trumpet interfaces. Hole count alone does not determine diameter. Ducts can be purchased separately.
Can ducts be purchased separately?
Yes. Round ducts, flat ducts and joints can be purchased separately, or supplied with TA anchors and tensioning equipment against the same drawing version. Lengths and accessories are itemized in the quotation.
How do I read a leak-resistance test result?
Check specimen, method, pressure, duration and criteria. Results apply to the tested samples and conditions; site connection and grouting follow project requirements.
Which public test reports are available for the ducts?
This page lists test reports for φ60 and φ90 round ducts and for flat ducts, issued by the National Metal Products Quality Supervision and Inspection Center. Results apply to the tested samples and conditions; batch documentation can be discussed when ordering.
