Hot Dip Galvanized Construction Fasteners Manufacturers

-- Steady & Reliable Manufacturer --

Introduction

Hot Dip Galvanized (HDG) construction fasteners are essential for building projects exposed to harsh outdoor or coastal environments. This process involves dipping the steel fasteners into molten zinc, creating a thick, durable coating that is metallurgically bonded to the base material. This provides superior corrosion resistance compared to standard zinc plating, ensuring the structural integrity of your construction over decades. We supply a full range of HDG products, including structural bolts, anchor bolts, and threaded rods.

Applications

  • Structural Steel Buildings: Connecting load-bearing beams and columns.

  • Highway & Bridge Construction: Critical for infrastructure exposed to weather and salt.

  • Utility Pole and Tower Assembly: Ensuring longevity in outdoor electrical and telecommunication systems.

  • Marine and Coastal Environments: Where high salinity demands maximum corrosion protection.

Advantages

  • Superior Corrosion Protection: The thick zinc layer forms a barrier and provides cathodic protection, significantly extending service life.

  • Cost-Effectiveness: Lower maintenance costs over time compared to less protected fasteners.

  • Abrasive Resistance: The metallurgical bond offers better resistance to damage during handling and installation.

  • Reliable Supply: Our factory maintains a stable inventory of common HDG construction standards.

Payment & Shipping

We accept secure international payment methods including Telegraphic Transfer (TT) and Letter of Credit (L/C). Shipping options include FOB, CIF, and DDP via major carriers or specialized freight forwarders, based on your volume and delivery needs. All shipments are securely packaged to prevent coating damage.

FAQ

  • Q: Does HDG affect the bolt strength?
  • A: The hot-dip galvanizing process can impact the mechanical properties of fasteners, particularly high-strength bolts (Grade 10.9 and higher). We adhere strictly to pre-treatment and post-treatment standards (like ASTM A490/A325 requirements) to ensure full strength retention and hydrogen embrittlement relief.
  • Q: How do I ensure thread compatibility?
  • A: We use specific tapping procedures for all HDG nuts, ensuring the internal thread is slightly oversized to accommodate the zinc coating on the bolt’s external thread, guaranteeing a smooth fit.
