HDG Thread Rod

Dazhe factory’ China HDG thread rod are fully threaded fasteners surface-treated via hot-dip galvanizing technology. The core advantage lies in the chemical reaction between the high-temperature molten zinc and the metal substrate, which forms a dense, corrosion-resistant zinc-iron alloy coating on the rod surface.

Hot-dip Galvanizing Process

The thread rod are immersed in molten zinc at a temperature of 440-480℃. A zinc-iron alloy layer is formed through the diffusion reaction between zinc and iron, providing full coverage on the rod surface.

Core Product Definition

Our HDG threaded rod is a fully threaded fastener, usually referring to a fully threaded stud or lead screw, with a uniform thread structure. It can be matched with various nuts to achieve position adjustment at will, featuring convenient and efficient installation. It is widely used in multiple fields such as industry, construction, and machinery manufacturing.

HDG threaded rods are threaded rods surface-treated by hot-dip galvanizing technology. The core advantage lies in the formation of a dense and corrosion-resistant zinc-iron alloy coating through the diffusion reaction between 440-480℃ high-temperature molten zinc and the metal substrate, which combines the general fastening performance of threaded rods and the super corrosion resistance of hot-dip galvanizing.
