Loop Box
Premium Loop Box – High-Performance Wire Rope Connection System for Precast Concrete
Our Loop Box provides a reliable, economical, and high-quality alternative to established systems like the Pfeifer VS® Box. It is specifically designed for secure connections of precast concrete elements such as walls, columns, panels, and more — ideal for both non-load-bearing and load-rated applications.
Key Features & Benefits
- Works Directly from Your Original Drawings
We manufacture using your provided original processing drawings, ensuring perfect dimensional fit, precise integration, and seamless compatibility with your existing precast production setup. - Extensive Pull-Break Testing for Maximum Safety
Every production batch undergoes rigorous sampling pull-out and breaking force tests. Our high-strength galvanized wire rope (typically 6 mm diameter, 1770 N/mm² nominal tensile strength, verified breaking load up to 48 kN) delivers proven safety and consistent quality you can trust. - Fully Automated High-Volume Production
State-of-the-art continuous automated machinery guarantees precise, efficient, and scalable manufacturing — ensuring strong delivery capacity even for large projects and tight deadlines without compromising quality. - Full Customization Without Patent Concerns
We support a wide variety of custom specifications: loop lengths, loop quantities, box dimensions, wire configurations, special coatings, and unique requirements — all engineered to avoid any patent-infringing designs while meeting your exact needs.
