Tie Rod & Formwork Accessories

Tie Rod (Dywidag)
The core of the formwork tie rod system. High tensile D15/17mm Dywidag Bar for securing concrete forms.

Wing Nut
Standard ductile iron nut used to secure the Dywidag bar against formwork walers. Quickly tightened with a hammer.

Anchor Nut
Heavy-duty Concrete Anchor Nut designed for use with large Super Plates for optimal load distribution.

Water Stopper
Cast iron barrier placed along the tie rod to prevent water leakage in concrete tanks and basement walls.

Hex Coupler
Long hexagonal connector used to join two tie rods together to extend the total length for thick walls.

Steel Cone
Used at the ends of PVC spacer tubes to create clean, conical holes in the concrete, allowing easy rod removal.

How the Formwork Tie Rod System Works
The Formwork Tie Rod System acts as the crucial "muscle" holding your concrete forms together. The high-tensile, threaded Dywidag Bar passes through the center of the wall formwork. On both exterior sides, Wing Nuts or a Concrete Anchor Nut are tightened against the steel walers.
This creates immense tension, securely holding the two Steel Formwork Panels in place against the massive outward pressure exerted by pouring wet concrete. For watertight structures like tanks, a Water Stopper is cast directly into the wall along the rod path.
Why Choose Taihe Tie Rods?
Quality Manufacturing & Reliable Performance.
Our Dywidag Bars are manufactured from high-grade steel, ensuring superior tensile strength for heavy loads.
Every batch of Tie Rod and Wing Nut combinations is tested on our 300KN machine to ensure compliance.
Large daily output of tie bars and casting nuts. We meet urgent delivery schedules with factory prices.
We provide free cutting service for tie rods (e.g. 1m, 3m) to save labor cost at your site.
Production Process
See how our high-strength Formwork Tie Rods are manufactured. The production process creates a continuous, self-cleaning Dywidag Bar thread that is durable and reliable under heavy concrete loads.
- ⚙️ Threading: Precision Dywidag thread pitch (6.35mm / 10mm).
- 🧪 Testing: Random sampling for yield and tensile strength.
Packing & Shipping

Tie rods are packed in secure bundles (e.g., 50/100 pcs) for easy crane loading. Wrapped with plastic to prevent rust during transit.

Wing nuts and anchor nuts are packed in durable woven bags (25kg/50pcs), then stacked on wooden or steel pallets for safe shipping.
FAQ: Tie Rod System
A: It depends on the steel grade. Our standard Q235 tie rods are weldable. However, high-strength 45# steel (C45) bars are heat-treated and not recommended for welding.
A: We offer Self Color (Black), Electro Galvanized, and Hot Dip Galvanized (HDG). For casting wing nuts, we recommend galvanizing for better rust resistance.
A: Our standard Ductile Iron Wing Nut has a minimum breaking load of 180KN - 190KN, perfectly matching the tensile strength of our D15/17 Tie Rod and Wing Nut systems.
A: Standard length for tie rods is 6 meters. We provide free cutting service to customized lengths (e.g., 1.0m, 3.0m) to save labor cost at your site.
A: Yes! We can send free samples of tie rod segments and wing nuts for quality checking. You only need to cover the courier freight.
A: Absolutely. Every shipment of formwork tie rods comes with a Mill Test Certificate indicating the steel grade, yield strength, and tensile strength results.
