Formwork Tie Rod – Secure Connections for Stronger Pours

Short Description:

When it comes to formwork accessories, tie rods and nuts form the critical connection chain that holds wall forms in position against concrete pressure. We supply tie rods in two primary diameter series—D15/17mm and D20/22mm—with the flexibility to produce any required length for specific project demands. The complementary nut range addresses every fastening scenario: round nuts for standard through-tie applications, wing nuts for quick installation/removal cycles, swivel nuts with round plates for non-perpendicular connections, hex nuts for maximum tightening torque, and specialized components including water stoppers for waterproofing and washers for load distribution.

Accessories: Tie rod and nut

Raw Materials: Q235/#45 steel/QT450

Surface Treatment: black/Galv.

Details Showing

We understand that quality standards vary significantly across different markets, and unfortunately, many end-users prioritize price over performance. To address this reality, we offer tiered product lines tailored to specific project requirements and budget constraints.

For premium applications where structural integrity is paramount, we recommend hot-rolled tie rods manufactured from #45 steel. Our D17mm option delivers exceptional tensile strength of 185-190kN, while the D20mm size achieves 200kN—providing the reliability that high-spec projects demand.

For cost-sensitive applications with less demanding requirements, our Q235 cold-drawn tie rods offer a practical alternative, with tensile strength ranging from 130-140kN—adequate performance at a more accessible price point.

This flexible approach ensures our clients receive the most cost-effective solution without paying for unnecessary capacity or compromising on essential safety.

Company Introduction

Tianjin Huayou Scaffolding Co., Ltd is located in Tianjin City, which can give us more support to choose different steel grade raw materials and also can control qualtiy.

For Formwork system, tie rod and nut are very important parts to connect whole system for concrete building. Currently, Tie rod have two different pattern, British and metric measurement. Steel grade have Q235 and #45 steel. But for nut, steel grade are all same, QT450, just looking and diameter different. Normal size are D90,D100,D110,D120 etc

Currently, our products are export to many countries that from South East Asia region, Middle East Market and Europe, America, etc.

Our principle: "Quality First, Customer Foremost and Service Ultmost." We devote ourselves to meet your

requirements and promote our mutually beneficial cooperation.
