PT Anchorages
PT Anchorages are carefully designed steel anchors that work behind the scenes, channeling powerful forces from prestressing tendons straight into the core of our structures. Whether discreetly concealed or elegantly showcased, these anchors serve as the steadfast support that keeps bridges, stadiums, and buildings resilient and reaching new heights. Next time you gaze at a concrete marvel, take a moment to appreciate the subtle strength of these unsung champions.
Anchor Cone (Tube Unit)
The Anchor Cone helps transfer the force from the Anchor Head to the concrete segment. It guides the high-tension strand into the duct, ensures a good fit, and allows for easy grout injection. This component is typically made of Cast Iron and is commonly used in prestressed concrete segments and girders.

Anchor Head
Anchor heads stand as the critical link between strength and stability in construction. They serve as the connection point for prestressing tendons, anchoring the force that fortifies our structures. We prioritize precision and durability in the design and production of anchor heads, ensuring they play a pivotal role in the structural integrity of bridges, buildings, and other architectural marvels. With our anchor heads, your construction projects gain a reliable foundation, embodying the strength necessary for structures to withstand the test of time.

Wedges
Wedges consist of conical-shaped components that are divided into three equal parts and secured around the strand using specialized wire circlips. The concave portion of each slit features threading that functions like a jaw, ensuring secure locking after undergoing stress. To attain exceptional quality and strength, precise hardening and tempering treatments are meticulously applied.
