Tie Rods Supplier

Stainless Steel Tie Rods Manufacturer in China

Stainless steel tie rod are indispensable components in structural engineering. Their core function is to provide structural stability and support by transmitting tensile loads. Profab’s stainless steel tie rod typically consist of a threaded rod and two rod ends. The combination of these two components enables precise length adjustment and tension regulation. The rod ends can be replaced with clevis or ball joints, among other options. These tie rods play a foundational role in many applications, such as supporting steel columns or heavy-duty wooden beams, as well as structures like canopies and sunshades.

Profab offers a wide range of configurations, grades, diameters, lengths, and surface finish options to meet diverse project requirements. In addition to the tie rods themselves, we also provide matching components such as nuts, basket bolts, connecting nuts, and fork heads. We are capable of providing complete engineering design specifications and ensuring that our products can be seamlessly integrated into your larger system.

Material Specification

Choosing the Right Grade

304 Stainless

Standard grade for indoor machinery, automation, and dry or mildly humid environments. Good resistance to cleaning chemicals. Cost-effective for high-volume orders. Not suitable for continuous salt spray or chloride-heavy process environments.

Food · Automation · Indoor

316 / 316L

Marine and food-grade standard. 2–3% molybdenum addition raises chloride pitting resistance significantly above 304. Required for outdoor, marine, offshore, and food equipment with CIP chemical cleaning. Especially 316 stainless steel has excellent resistance to corrosive saltwater effects.

Marine · Chemical · Pumps

17-4PH

Precipitation-hardened martensitic grade. ≥ 1,310 MPa tensile strength in H900 condition — significantly stronger than 316 at equivalent cross-section. Specified for ball joints in motorsport, aerospace, and high-cycle fatigue applications where load ratings are the primary constraint.

Applications

Where Stainless Steel Tie Rods Are Used

Stainless steel tie rods play a key role in a wide range of industrial and professional fields thanks to their outstanding performance. They provide structural support, tension adjustment, and reinforcement for various complex projects.

Agricultural Machinery

They ensure stable steering, precise linkage, and reliable load transfer in tractors, harvesters, and other agricultural equipment.

Marine

In boats and offshore platforms, these components secure steering arms and mechanical linkages, maintaining precise control under harsh marine conditions.

Automotive

Front suspension assemblies rely on tie rods to maintain wheel alignment and directional stability during driving.

Chemical Processing

In agitator systems and mixing machinery, tie rods stabilize support frames and transmit mechanical loads during continuous operation.

Construction

Structural steel frameworks use tie rods between beams and columns to prevent lateral movement and maintain overall rigidity.

Aerospace

Inside landing gear mechanisms, ss tie rods stabilize linkage geometry and help manage high impact loads during takeoff and landing.

Technical Reference

Load Capacity Reference

The core design purpose of a tie rod is to withstand tensile loads and to transfer those loads between structural members. To ensure structural safety, it is essential to understand its mechanical properties, including tensile strength, yield strength, elongation, and hardness. Relevant industry standards—such as ASME B31.1, MSS SP-58, and AISC 360-16—define the allowable stresses and load-bearing capacities. For tie rods of various diameters and material strengths, corresponding allowable tensile capacity data are available for reference.

The table below presents example load capacities for stainless steel tie rods. Please note that these values are for reference only. The final design for any specific project should be based on detailed engineering calculations and the applicable standards.

Tie rod diameter (inches/mm)	Material grade	Allowable tensile load capacity (lb/kN)	Coarse thread root area (square inches)
1/4″	304 SS	240 pounds	0.027
3/8″	304 SS	610 pounds	0.068
1/2″	304 SS	1130 pounds	0.126
5/8″	304 SS	1810 pounds	0.202
3/4″	304 SS	2710 pounds	0.302
7/8″	304 SS	3770 pounds	0.419
1″	304 SS	4960 pounds	0.552
1-1/4″	304 SS	8,000 pounds	0.889

Note: The above data is based on ASTM A36 steel threaded rod, per ASME B31.1 and MSS SP-58 standards, with an allowable stress of 12,000 psi and a 25% reduction based on the thread root area. 28 For other material grades (such as 316 SS) or specific applications, please refer to the appropriate standards or consult a professional engineer.

Installation Tips

Proper installation is critical to ensure the long-term performance and safety of your tie rods:

Proper torque application: When tightening nuts, always apply torque according to the manufacturer’s specifications. This prevents distortion, vibration, and premature wear.
Centering the stud: Ensure that the stud is centered in the ball and socket during installation. This exte nds the life of the tie rod ends and prevents excessive play or rattling.
Periodic inspection: It is recommended that the joints be inspected for excessive play during wheel alignment or tire rotation.
Wheel alignment after replacement: The adjustable nature of the tie rods means that each installation affects the vehicle’s wheel alignment angle, particularly the front beam angle. Skipping this critical step can lead to erratic handling, accelerated tire wear and potentially dangerous driving conditions.
Professional installation: Considering the importance of steering components to safety and the special tools, removal, torque specifications and wheel alignment requirements required, it is recommended that installation be performed by a professional.
