Application
Steel formwork tensioning, aluminum formwork tensioning, and concrete formwork fastening.
Steel Bars
Fine-Rolled Threaded Steel Bar
Continuous-thread steel bar for prestressing, structural connection, anchoring and geotechnical reinforcement.
PRODUCT OVERVIEW
Formwork Tie Rod (Dywidag-type)
Threaded steel bars for prestressed concrete (often referred to as "precision-rolled threaded bars") are large-diameter, high-strength, and high-precision straight bars featuring discontinuous external threads rolled along their entire length. These bars allow for connections via internally threaded couplers or anchoring via threaded nuts at any point along the bar. They offer advantages such as convenient connection and anchoring, safe and reliable tensioning, simplified construction, and a reduction in structural cross-sectional area and weight.
Configuration
30×50 high-strength nut, 30×100 high-strength nut, wing nut with round plate, water-stop connector
Specification
The standard specifications are: #15#20, #22, #25, #28, #32, #36, #40, #50, #57.5#65#75
Supply format
Cut length, surface condition, packing and marking confirmed for each order.
