Precast Loop Box – Efficient & Secure Panel Connections
Our galvanized steel Precast Loop Box is designed to simplify and strengthen panel-to-panel and panel-to-column connections in precast concrete construction.
Installed during formwork setup, it features high-strength (≈1770 MPa) wire‑rope loops housed in a durable steel casing, secured with color-coded tape
After casting, simply remove the tape and snap the loops into place on-site. Adjacent panels are linked using rebar through the loops, then grouted to create a high-load bearing joint that resists tension, shear, and axial forces .
Available in single, double, and multi‑loop variants, our loop boxes are customizable by size, loop count, and spacing to meet your project needs.
With quick installation (cutting labor time by ~50 %) and no rebar clashes, they deliver reliable, code-compliant (~EN1992‑1‑1) connections every time
