According to the Global Concrete Accessories Market Report 2023, demand for robust concrete form tie solutions is projected to grow at a CAGR of 5.4% through 2028, driven by increased infrastructure investment and stricter safety standards. Snap ties, wall ties, and upgradeable form tie formwork system designs address rising performance and sustainability requirements worldwide.

Type | Standard Size | Yield Strength (MPa) | Coating | Use Case | Corrosion Resistance |
---|---|---|---|---|---|
Form Tie Nut | M12, M16, M20 | >350 | Hot-dip Galvanized | Walls, Columns, Slabs | High |
Snap Tie | 1/2", 5/8" | 320~380 | Electroplated | Retaining Walls | Moderate |
Through Rod Tie | Ø15/17mm | >400 | Epoxy | High-pressure forms | Excellent |
Taper Tie | 16/22mm | 380~410 | Galvanized | Bridges, Marine | Superior |
The selection between concrete formwork snap ties, standard concrete formwork ties, and reinforced concrete wall form tie products depends on project load, design geometry, durability expectations, and exposure class.

-
1. Raw Material Selection
High-quality low-carbon steel or ductile iron per ISO 6931, for max. ductility and strength. -
2. Forging & CNC Machining
Billet is hot-forged & precision-machined (CNC) to tolerance ≤0.08mm, ensuring thread conformity (metric/imperial) and superior mechanical interlock. -
3. Surface Treatment
Hot-dip galvanization or zinc-plating per ASTM A153/BS 729 for anti-corrosion; optional epoxy for harsh field applications. -
4. Performance Testing
Every batch undergoes pull test (≥2X rated load), salt-spray test (≥400h), dimensional measurement per ISO 2859. -
5. Marking & Packing
Each concrete form tie is batch-marked, barcoded, and anti-impact packaged for global export logistics.


All products are manufactured to ISO 9001 and comply with ANSI A10.9 standards for construction hardware, ensuring international certification and traceable quality.
