ASTM A307 Grade A All Thread Rods with Hot Dipped Galvanized Plating

ASTM A307 Grade A All Thread Rods – Hot-Dip Galvanized (HDG)

Rugged Corrosion Protection for Outdoor and Structural Applications

ASTM A307 Grade A all thread rods with hot-dip galvanized (HDG) plating are the go-to fastening solution for general-purpose structural and construction projects where enhanced corrosion resistance is required. Manufactured from low carbon steel, these rods are designed for light to medium-duty applications and provide long-lasting durability in outdoor or exposed environments.

What Is ASTM A307 Grade A?

ASTM A307 Grade A defines the standards for low carbon steel fasteners used in non-critical structural connections. These fully threaded rods are ideal for use in suspension, bracing, anchoring, and light framing systems.

With UNC (Unified National Coarse) threading, these rods are compatible with standard nuts and washers, allowing for quick and easy assembly in the field.

Benefits of Hot-Dip Galvanized Finish

Hot-dip galvanizing adds a thick, bonded layer of zinc that protects the steel from rust and corrosion. Key advantages include:

• ✅ Superior corrosion resistance for outdoor or high-moisture environments

• ✅ Ideal for treated lumber, decks, and structural steel installations

• ✅ Longer lifespan compared to electroplated zinc finishes

• ✅ Excellent performance in infrastructure and utility construction

Sizes and Common Uses

These rods are available in diameters from 1/4" to 1-1/2" and in lengths such as 6', 10', and 12', with custom sizes available. Common applications include:

• Outdoor framing and anchoring

• Utility pole hardware and fencing

• HVAC and plumbing support in damp environments

Dependable Strength Meets Outdoor Durability

When your project requires cost-effective fastening with maximum weather resistance, ASTM A307 Grade A all thread rods with hot-dip galvanized plating are built to last.
