This ensures a precise fit and interchangeability for standard metric and inch pipe sizes, providing a reliable and consistent clamping solution.<\/li>\n<li><strong>U-Shaped Design for Secure Clamping:<\/strong> The distinctive U-shape is designed to wrap around the circumference of a pipe or tube. When the two threaded ends are inserted through mounting holes and tightened with nuts, they create a strong, evenly distributed clamping force that firmly holds the component in place, preventing movement and vibration.<\/li>\n<li><strong>Material and Finish Options:<\/strong>\n<ul>\n<li><strong>Carbon Steel:<\/strong> For high-strength applications, we offer U-bolts made from carbon steel in various grades (e.g., 4.8, 8.8). These are typically coated for corrosion protection. <strong>White Zinc Plating<\/strong> is a standard finish offering good rust resistance for general and indoor use. For more demanding outdoor or corrosive environments, a <strong>Hot-Dip Galvanized (HDG)<\/strong> finish can be provided.<\/li>\n<li><strong>Stainless Steel (A2\/304, A4\/316):<\/strong> For applications requiring maximum corrosion resistance, such as in marine, chemical, or food processing environments, we offer U-bolts made from A2 (304) or A4 (316) stainless steel.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Dual Threaded Ends:<\/strong> Each U-bolt features two threaded legs, allowing for secure fastening with two nuts (and washers). This dual-point connection provides superior stability and holding power compared to single-point fasteners.<\/li>\n<\/ul>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<p>The technical specifications for our DIN 3570 U-bolts are detailed below to ensure they meet your project&#8217;s exact requirements.<\/p>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Specification<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>DIN 3570 U-bolts<\/td>\n<\/tr>\n<tr>\n<td><strong>Standard<\/strong><\/td>\n<td>DIN 3570<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel, Stainless Steel (304\/A2, 316\/A4)<\/td>\n<\/tr>\n<tr>\n<td><strong>Grade<\/strong><\/td>\n<td>Carbon Steel: 4.8, 8.8, 10.9, 12.9; Stainless: A2-70, A4-70, A4-80<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface Treatment<\/strong><\/td>\n<td>White Zinc Plated, Hot-Dip Galvanized (HDG), Plain (for Stainless)<\/td>\n<\/tr>\n<tr>\n<td><strong>Size Range<\/strong><\/td>\n<td>30mm \u2013 530mm (Nominal diameter corresponding to pipe size)<\/td>\n<\/tr>\n<tr>\n<td><strong>Brand Name<\/strong><\/td>\n<td>Duojia<\/td>\n<\/tr>\n<tr>\n<td><strong>Place of Origin<\/strong><\/td>\n<td>Hebei, China<\/td>\n<\/tr>\n<tr>\n<td><strong>Key Feature<\/strong><\/td>\n<td>Secure, standardized clamping for pipes, tubes, and rods<\/td>\n<\/tr>\n<tr>\n<td><strong>Application<\/strong><\/td>\n<td>Heavy Industry, General Industry, Construction, Pipeline Support<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Product Features<\/strong><\/h4>\n<p>Our DIN 3570 U-bolts are engineered with features that guarantee strength, durability, and ease of use.<\/p>\n<ul>\n<li><strong>Robust Clamping Force:<\/strong> The U-shape and dual-nut design provide a powerful and balanced grip, securely immobilizing pipes and preventing slippage or rotation.<\/li>\n<li><strong>Excellent Corrosion Resistance:<\/strong> With options for zinc plating, hot-dip galvanizing, or solid stainless steel construction, our U-bolts are built to withstand rust and corrosion in various environments.<\/li>\n<li><strong>Standardized for Perfect Fit:<\/strong> Adherence to the DIN 3570 standard ensures that the U-bolt dimensions are perfectly matched to standard pipe sizes, simplifying selection and guaranteeing a proper fit.<\/li>\n<li><strong>High Strength and Durability:<\/strong> Available in high-strength carbon steel grades, these U-bolts can handle heavy loads and provide long-lasting structural support.<\/li>\n<li><strong>Versatile Application:<\/strong> Ideal for more than just pipes, these U-bolts are also used to secure cables, conduits, structural framing, and even as an anchor point in concrete.<\/li>\n<\/ul>\n<h4><strong>Product Applications<\/strong><\/h4>\n<p>DIN 3570 U-bolts are a fundamental component in a multitude of industrial, commercial, and residential applications.<\/p>\n<ul>\n<li><strong>Pipe and Conduit Support:<\/strong> Their primary use is to support and restrain pipes for plumbing, HVAC, process piping, and electrical conduit systems, securing them to walls, ceilings, or structural beams.<\/li>\n<li><strong>Structural Connections:<\/strong> Used in construction to fasten round or square posts, beams, and framing members to other surfaces.<\/li>\n<li><strong>Automotive and Transportation:<\/strong> Commonly used in vehicle suspension systems (e.g., to attach axles to leaf springs), secure exhaust pipes, and mount components to vehicle frames.<\/li>\n<li><strong>Marine and Coastal Installations:<\/strong> Stainless steel U-bolts are essential for securing rigging, railings, and equipment on boats and docks due to their superior resistance to saltwater corrosion.<\/li>\n<li><strong>Telecommunications:<\/strong> Used for mounting antennas, satellite dishes, and cabling to masts and towers.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>As a premier factory and manufacturer in China, we provide high-quality DIN 3570 U-bolts, the definitive solution for industrial pipe and tube fastening.
