Product Introduction

The Dacromet-coated gauge block (Type 20#) is a critical component within railway fastening systems. It is primarily used in the assembly that secures rails to sleepers, functioning alongside tension clamps, gauge block seats, screw spikes, and other fastening hardware.

Henan Xinda Railway Equipment Co., Ltd. specializes in railway equipment and track fastening components, dedicated to providing essential hardware for railway construction, track maintenance, and related engineering projects. The company’s Dacromet-coated gauge blocks (Type 20#) are manufactured in strict accordance with technical specifications and undergo a Dacromet anti-corrosion surface treatment, ensuring they meet all requirements for structural integrity, dimensional precision, and corrosion resistance within railway fastening systems.

In railway infrastructure, gauge blocks serve to laterally constrain the rails, transmit lateral forces, and help maintain a stable track gauge; they are vital components for ensuring the overall stability of the track structure.

 Key Product Features

• Dacromet Anti-Corrosion Surface Treatment: The 20# gauge baffle supplied by Henan Xinda Railway Equipment Co., Ltd. utilizes the Dacromet (zinc-chromium coating) anti-corrosion process. By forming a protective layer on the metal surface, this process enhances the product's corrosion resistance, mitigates the impact of humid environments and external corrosive factors on the metal substrate, and helps extend the product's service life.
• Optimized Structural Design: The product is manufactured in accordance with the design specifications of the relevant rail fastening system. Precision in dimensions, hole positioning, and contact surfaces ensures a seamless fit with other components of the fastening assembly.
• Effective Positioning and Compatibility: The gauge baffle works in conjunction with other fastening components to provide lateral restraint for the rail. It also helps transmit a portion of the lateral forces exerted on the rail, contributing to the overall stability of the track structure.
• Versatile Application for Engineering Requirements: Depending on the specific fastening system and track design specifications, the product can be utilized in various scenarios, including the construction of new railway lines, the maintenance of existing lines, routine track upkeep, and the replacement of railway components.

Production Process and Quality Control

Although rail gauge clips are fundamental components within a rail fastening system, their manufacturing quality, dimensional precision, and surface anti-corrosion performance significantly influence both their installation fit and long-term operational reliability. Henan Xinda Railway Equipment Co., Ltd. places great emphasis on the quality and production processes of its railway components, focusing specifically on the following areas throughout the supply process: raw material control, machining precision, surface anti-corrosion treatment, and final product quality inspection.

Henan Xinda Railway Equipment Co., Ltd. specializes in the supply of railway equipment and provides support for railway engineering construction. We remain steadfastly committed to product quality and meeting our customers' needs, offering professional railway equipment and related services to clients across the railway industry.
