Post-Tensioning

Post-Tensioning

LMK Advantages

• Compact anchorages to facilitate the installation and grouting of the tendons.
• Anchorages design to satisfy the Design requirements of Int’l Standards, European (EN ‐ ETAG 013) & AASHTO LRFD‐10, F.I.B. (International Concrete Federation) & PTI (Post Tensioning Institute) Recommendations.
• Wide selection of anchorages & jacks from 1 up to 37 strands (round) & 2 up to 5 strands (flat) allowing the Consultants to provide an economical design and specify improved technical feasibilities (proper cable deviations & losses).
37 different anchorage sizes and different types contributing to the Economy of the Design & Construction.
Easy connection with standard or enlarged steel or plastic sheaths (flat and round).
