These machines precisely cut, bend, and form the steel into the intricate shapes required for optimal performance, such as the double pintle design for adjustable masonry ties.
3. Welding and Assembly (if applicable): For multi-component masonry tie systems, automated welding processes (e.g., resistance welding, MIG/TIG) are employed to create strong, consistent joints. This ensures the integrity of assemblies like wire masonry ties to concrete anchors.
4. Surface Treatment: Galvanized steel ties undergo hot-dip galvanization or electro-galvanization post-fabrication, providing a protective zinc coating. Stainless steel components are often passivated to enhance their inherent corrosion resistance.
5. Quality Control and Testing: Each batch undergoes comprehensive testing, including tensile strength tests, shear resistance tests, and salt spray corrosion tests, adhering to international standards such as ISO 9001 and ANSI ACI 530/ASCE 5/TMS 402. This ensures that every masonry tie meets or exceeds specified load-bearing capacities and environmental resilience.
6. Packaging and Traceability: Products are carefully packaged to prevent damage during transit, with full traceability maintained from raw material to finished product.

This meticulous process ensures a service life often exceeding 50 years, even in challenging conditions. Our products find application across diverse industries, including petrochemical, metallurgy, and water supply & drainage, where their energy-saving properties (by maintaining thermal envelope integrity) and superior corrosion resistance are critical for long-term operational reliability.
