High-Precision DIN 3570 Stainless Steel U-Bolt Pipe Clamp

Product Overview 

Our DIN 3570 U-bolt pipe clamps are engineered for reliable pipe positioning, restraint, and structural support. Manufactured to exacting standards, these U-bolts feature precision threads and a plain (uncoated) finish, making them ideal for direct metal-to-metal contact or secondary coating applications. Available in premium 304 and 316 stainless steel (A2-70 and A4-80 grades), they provide excellent corrosion resistance for building and piping projects.

Why Choose Our DIN 3570 U-Bolts?

1. Precision Threads for Secure Assembly
Every U-bolt is manufactured with precise thread dimensions and pitch. This ensures smooth nut engagement, consistent clamping force, and reduced risk of thread stripping during installation.

2. Premium Stainless Steel Options
Choose between 304 (A2) for general outdoor/indoor environments and 316 (A4) for highly corrosive environments (e.g., coastal, marine, or chemical exposure). Both grades offer high tensile strength and long service life.

3. Plain Finish for Versatility
The plain surface finish (without additional electroplating) eliminates the risk of coating flaking during tightening. It is ideal for applications where the U-bolt will be painted, powder-coated, or used in clean room environments.

4. Built for Piping and Structural Support
Designed to firmly secure pipes to struts, brackets, or structural surfaces. The DIN 3570 geometry provides a secure envelope for pipe restraint without excessive stress concentration.

Frequently Asked Questions

Q1: Are these U-bolts suitable for outdoor use?
Yes. Both 304 and 316 stainless steel offer excellent outdoor corrosion resistance. For coastal areas, 316 is highly recommended.

Q2: Can you customize the thread length and bolt length?
Absolutely. Our standard length range is 10-160mm, but we support custom dimensions to meet specific project requirements.

Q3: How do I choose between 304 and 316?
304 is ideal for standard atmospheric environments. 316 contains molybdenum, making it superior for environments with chlorides, such as saltwater or de-icing salts.

Q4: What is the difference between A2-70 and A4-80?
A2-70 refers to 304 stainless steel with a minimum tensile strength of 700 N/mm². A4-80 refers to 316 stainless steel with a minimum tensile strength of 800 N/mm².
