Hot Dipped Galvanized Drop In Anchor

Hot Dipped Galvanized Drop In Anchor is manufactured from standard Q235 low carbon steel that meets GB/T 700 material specification, with minimum tensile strength reaching 375MPa and yield strength above 235MPa, fully compatible with C20, C25, C30, C35 and C40 concrete substrates widely used in global construction projects. The whole anchor body adopts integrated seamless tube forging molding, eliminating hidden cracks caused by secondary welding which commonly exist in low-cost imitation anchor products. The special diamond knurling section processed on the anchor outer wall raises friction coefficient by 42% compared with smooth surface anchor tubes, this design effectively prevents the anchor from sliding displacement during static and dynamic tension load tests. Ningbo Gangtong Zheli Fastener Co., Ltd arranges full-size random inspection for every production batch, inspecting thread depth, pipe wall thickness and knurl completeness to ensure each finished anchor matches standard installation tolerance.

Anti-Corrosion Surface Treatments & Wide Application Fields

Except the core anti-rust finish for outdoor projects, the factory also provides electro galvanized and 304 stainless steel alternatives to satisfy different environmental corrosion resistance demands. The anti-corrosion performance of Hot Dipped Galvanized Drop In Anchor strictly complies with ISO 1461 international hot-dip galvanizing standard, the galvanized layer thickness ranges from 85μm to 110μm, which can resist continuous salt fog test over 500 hours without rust spots, suitable for coastal areas, open-air municipal engineering and photovoltaic power station projects. Complete specification series covers M6, M8, M10, M12, M14, M16, M18 and M20, all mainstream sizes maintain continuous spot stock to support small trial orders and large bulk wholesale orders. Common application scenarios include solar bracket fixation, pipeline support installation, curtain wall embedded fixing, mechanical equipment base anchoring, highway guardrail auxiliary fixing and indoor ceiling suspension installation.

Production Capacity, Quality Inspection & Global Cooperation Layout

The standardized fastener production workshop is equipped with 12 sets of fully automatic CNC forging machines and 4 supporting galvanizing production lines, the daily finished output of anchoring hardware reaches 85,000 pieces to sustain steady supply for long-term overseas partners. Every finished anchor must pass three rounds of testing before delivery: dimensional tolerance detection, galvanized layer thickness test and third-party tension load certification, all test reports can be provided to customers for engineering filing use. With 11 years of professional fastener foreign trade operation experience, Ningbo Gangtong Zheli Fastener Co., Ltd has built stable long-term cooperative relations with hardware distributors, construction material wholesalers and engineering contractors across South America, Southeast Asia, Eastern Europe and Middle East regions. All qualified Hot Dipped Galvanized Drop In Anchor features precise uniform threading and consistent tube wall thickness, ensuring perfect fitting with standard matched bolts and accessories. It supports quick and convenient manual installation without professional large-scale equipment, greatly improving construction efficiency and reducing on-site labor costs for various engineering projects.
