Product Overview
Formwork Tie Rods are high-precision structural components engineered to maintain uniform wall thickness and ensure absolute structural stability during the concrete pouring process. Essential for residential buildings, commercial structures, and large-scale civil engineering works like bridges, these tie rods prevent formwork deformation under the immense pressure of wet concrete, resulting in high-quality, professional finishes.
WRK specializes in manufacturing tie rods using premium-grade steel, ranging from low-carbon Q235 to high-strength Grade 830. By integrating rigorous material testing with advanced threading and galvanization processes, we provide reliable fastening solutions that meet strict international construction safety standards, ensuring maximum load-bearing capacity and corrosion resistance for any job site.
