Corrosion-Resistant Color Zinc Plated Carbon Steel Anchor Bolts with Hex Flange Nuts

2.Key Features:

1. High Strength from Carbon Steel Construction

• The base material—carbon steel—delivers excellent tensile strength and shear resistance, enabling the system to withstand heavy static loads (e.g., building structural weight) and dynamic forces (e.g., vibration from machinery).
• For demanding applications, bolts may be heat-treated to meet industry strength grades (e.g., 8.8-grade bolts, which can withstand a minimum tensile strength of 800 MPa), ensuring long-term structural stability without deformation or breakage.

2. Superior Corrosion Resistance via Color Zinc Plating

• Color zinc plating forms a dense, adherent zinc alloy film on the surface of the bolts and nuts. This film acts as a physical barrier, isolating the carbon steel from moisture, oxygen, salt spray, and industrial fumes—common causes of rust and oxidation.
• Compared to standard clear zinc plating, color zinc plating offers 30–50% better corrosion resistance (tested via neutral salt spray tests, often lasting 48–72 hours without red rust). This makes the system suitable for indoor humid environments (e.g., factories, basements) and mild outdoor settings (e.g., covered parking structures).
• The colorful finish also provides visual clarity: it helps workers identify installed fasteners easily and check for damage (e.g., chipped plating) during inspections.

3. Hexagon Flange Nuts for Enhanced Stability & Convenience

• The integrated flange on the nut replaces traditional flat washers, saving installation time and reducing the risk of missing parts. The flange’s wide bearing surface distributes clamping force evenly across the workpiece, preventing damage to soft materials (e.g., painted steel) and reducing the chance of the nut loosening due to vibration.
• The hexagonal nut shape is compatible with standard wrenches and socket tools, allowing for quick, secure tightening—even in tight spaces where power tools may be hard to maneuver.

4. Secure Anchoring Performance

• Anchor bolts are designed to create a permanent bond with base materials:
  • Expansion anchor bolts: Feature a cone-shaped sleeve that expands when the bolt is tightened, gripping the concrete tightly.
  • Chemical anchor bolts: Use epoxy resin to bond the bolt to the drilled hole, ensuring uniform load distribution and resistance to pull-out.
• This secure anchoring prevents shifting or detachment of heavy structures, even under extreme conditions (e.g., strong winds, seismic activity).

5. Versatility Across Applications

• The system is adaptable to diverse scenarios:
  • Construction: Securing steel beams, prefabricated walls, and concrete formwork.
  • Industrial: Fixing heavy machinery (e.g., generators, conveyors) to factory floors.
  • Infrastructure: Installing traffic signs, street lamps, and guardrails.
• It works with multiple base materials, including concrete, brick, stone, and thick metal plates.

6. Cost-Effective Durability

• Carbon steel is an affordable alternative to stainless steel, while color zinc plating extends the fasteners’ service life—reducing the need for frequent replacement and maintenance costs.
• The all-in-one bolt-and-nut design lowers inventory costs (no need to stock separate washers) and minimizes installation errors (e.g., mismatched washer sizes).
