Product Description

Product Overview

Detailed introduction of galvanized wire rod and screw products, focusing on high-performance transmission and anti-corrosion capabilities.

Definition: Galvanized screw is a transmission component coated with a zinc layer (electroplated or hot-dip) on the surface. It converts rotational motion into linear motion while providing superior anti-corrosion protection.
Core Structure
  • Base Material: High-quality carbon steel (45# steel, 40Cr) or stainless steel base.
  • Thread Type: Available in trapezoidal thread (Tr type) or high-precision ball screws.
  • Galvanizing Process: Options include uniform electroplated zinc or heavy-duty hot-dip zinc coating.
Application Scenarios
🏗️ Outdoor Machinery

Ideal for construction and agricultural equipment exposed to rain and soil.

⚓ Ship & Ocean Engineering

Deck lifting and valve controls resistant to salt spray corrosion.

🧪 Chemical Equipment

Transmission systems in reaction kettles resistant to acid and alkali media.

🏢 Construction Industry

Automatic doors, windows, and lifting platforms requiring rust prevention.

🍲 Food Processing

Hygiene-compliant smooth surfaces with zero rust contamination risk.

Frequently Asked Questions
Q What is the difference between electroplated and hot-dip zinc?
Electroplated zinc provides a thinner, smoother, and more uniform coating for precision parts. Hot-dip zinc offers a much thicker coating, providing superior durability for harsh outdoor or marine environments.
Q Which materials are used for the base of the screws?
Commonly used base materials include carbon steel grades like 45# and 40Cr, as well as various grades of stainless steel, depending on the required mechanical strength.
Q Can these be used in food-grade environments?
Yes, provided they meet specific hygiene standards. Their smooth, rust-resistant surface prevents contamination, making them suitable for many food processing machinery applications.
Q Are they resistant to saltwater?
Yes, especially hot-dip galvanized versions. They are specifically designed to resist salt spray corrosion in marine and offshore engineering applications.
Q What thread types can I choose?
We offer standard trapezoidal threads (Tr type) for general use and ball screw configurations for high-precision, low-friction requirements.
Q How do they handle chemical exposure?
They offer good resistance to mild acids and alkalis. For extremely aggressive chemical environments, we recommend specific material consultations.
