Adjustable Formwork Tie Rod and Nut Assembly for Wall Forming

Short Description:

Formwork accessories cover a broad range of components, yet the tie rods and nuts stand out as the core parts that secure formwork panels firmly against concrete walls. Tie rods commonly come in diameters of 15/17mm and 20/22mm, with lengths tailored to each project’s specifications. The nut family is diverse—round nuts, wing nuts, swivel nuts with round plates, hex nuts, water stoppers, and washers are all available to suit different connection needs.

Accessories: Tie rod and nut

We supply D15/17mm and D20/22mm tie rods in custom lengths to match your project specifications. A full range of nuts is available—round nuts, wing nuts, swivel nuts with round plates, hex nuts, water stoppers, and washers—to suit different forming requirements. All components are designed for reliable performance, quick assembly, and easy stripping. Tell us your size and type needs, and we will deliver the right combination for your job.

Details Showing

The reality is that quality expectations vary significantly across regions. Many buyers focus primarily on unit price without fully understanding the performance differences. That is why we offer tiered quality options to match real project needs.

For premium applications, we recommend #45 steel with hot-rolling process. At D17mm, tensile strength reaches 185-190kN; at D20mm, it delivers 210kN. For cost-sensitive projects, Q235 steel with cold-drawing is a viable alternative, though tensile strength is limited to 130-140kN.

Testing Report

Quality control at our facility follows a disciplined path from the moment steel enters our workshop until the final container is sealed. Every batch passes through multiple inspection checkpoints, and our QC team signs off at each stage before any product leaves the warehouse.

We do not apply a one-size-fits-all approach. Based on your budget and performance needs, we recommend the most suitable grade for tie rods and nuts. All testing is carried out in line with GB/T28900 and GB/T 228 standards.

Advantages

1. Flexible Material Options for Different Budgets
We offer tiered quality choices—#45 hot-rolled steel for high-strength requirements (185-190kN tensile strength) and Q235 cold-drawn steel for cost-sensitive projects (130-140kN). You pay for what you actually need, not a one-price-fits-all.

2. Dual Measurement Systems Available
Both British and metric thread patterns are supported, making our tie rods compatible with formwork systems used across different regions without modification.

3. Complete Nut Range for Every Connection
We supply round nuts, wing nuts, swivel nuts with round plates, hex nuts, water stoppers, and washers in common sizes D90/D100/D110/D120. All nuts use QT450 ductile iron for consistent strength and durability.

4. End-to-End Quality Control
Our QC team monitors every stage from incoming raw steel to container loading. Each batch is inspected thoroughly before leaving the warehouse, so you receive products in proper condition.

5. Proven International Track Record
Our formwork tie rods and nuts are already used in Southeast Asia, the Middle East, Europe, and the Americas. The products have been tested across diverse site conditions and climates.

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.
