Hot Dip Galvanized Tension Indicator Flat Washer

Hot Dip Galvanized Tension Indicator Flat Washer is a special structural fastener accessory for steel engineering connection, forged from medium carbon steel with stable mechanical performance. The product surface supports multiple anti-corrosion treatments including black oxide, mechanical galvanizing, Dacromet and hot dip galvanizing, which can adapt to indoor and outdoor construction environments with different salt spray resistance requirements. The convex indent design on the surface of Hot Dip Galvanized Tension Indicator Flat Washer can present the pre-tightening state of bolts through deformation, helping construction inspectors quickly judge whether the bolt locking force reaches the design standard. Ningbo Gangtong Zheli Fastener Co., Ltd has built a complete production line for structural gaskets, and all raw steel materials are purchased from qualified domestic steel mills with complete material test reports.

Core Performance & Application Scenarios

All specifications of this structural gasket have passed physical tensile and anti-rust tests, with a maximum bearing load matching the supporting high-strength structural bolts ranging from M16 to M36. Construction industries such as steel bridges, factory steel frames, high-rise building steel structures and wind power support frames are the main application markets of this product. The deformation feedback function of Hot Dip Galvanized Tension Indicator Flat Washer effectively reduces the hidden danger of loose bolt connections caused by long-term vibration of building structures, and greatly improves the safety detection efficiency of engineering acceptance. Our factory can provide customized aperture and thickness parameters according to customers’ engineering drawings, and maintain regular stock of conventional size gaskets to meet the small batch trial order and large batch bulk order demands of global engineering purchasers.

Production Strength & Global Service

The production workshop of Ningbo Gangtong Zheli Fastener Co., Ltd covers a processing area of over 3,000 square meters, equipped with automatic stamping, heat treatment and coating integrated processing equipment, and the daily output of structural flat washers can reach more than 80,000 pieces. All finished gaskets will be sampled for tension detection before delivery to ensure that each batch of goods meets the international structural connection standards. Customers can choose to purchase separate gaskets or match them with high-strength bolts, nuts and other supporting fasteners as a complete set. After years of overseas market operation, our structural fasteners have been exported to Southeast Asia, the Middle East and European engineering markets, and many long-term cooperative engineering suppliers have placed repeated orders for our coated structural gaskets. The stable processing technology and strict quality inspection system make Hot Dip Galvanized Tension Indicator Flat Washer obtain consistent recognition from global construction purchasers.
