Wedge Anchors are mechanical fasteners designed to secure heavy loads to concrete, brick, or stone by expanding a wedge against the substrate when tightened. Ideal for structural and non-structural applications, they consist of a threaded bolt, expandable sleeve, and nut, providing high tensile and shear strength. Manufactured from carbon steel (zinc-plated), stainless steel (304/316), or alloy steel (Grade B7), they offer durability in harsh environments.
- Material:
- Carbon Steel: Grade 4.8/8.8 (zinc-plated or hot-dip galvanized).
- Stainless Steel: 304 (A2) for general corrosion resistance; 316 (A4) for marine/chemical environments.
- Alloy Steel: ASTM A193 Grade B7 (heat-treated for high-temperature/high-strength use).
- Size Range:
- Diameter: M6–M36 (metric) / 1/4"–1-1/2" (imperial).
- Length: 30–300 mm (embedment depth varies by substrate thickness).
- Design Features:
- Wedge Sleeve: Split design that expands radially when the nut is tightened.
- Threaded Shank: Full or partial threads for compatibility with nuts and washers.
- Head Style: Hex head (standard) or countersunk for flush installations.
- Load Capacity:
- Tensile Strength: 1,000–20,000 kg (depending on size and material).
- Compliance: Meets ANSI/ASME A325.1 (USA) and EN 15048 (Europe) for structural applications.
- Standard Carbon Steel/Zinc-Plated (M10–M20): 5,000 pieces (in-stock sizes).
- Stainless Steel (304/316): 2,000 pieces (custom lengths available).
- Alloy Steel/Heavy-Duty (M24+): 1,000 pieces (project-based orders).
Factory Advantages: ISO 9001-certified production, 100% load testing for critical applications, and support for non-standard embedment depths or corrosion-resistant coatings (e.g., Dacromet) with lead times of 15–30 days.
- Construction: Securing steel columns, machinery bases, and railings to concrete foundations.
- Industrial: Mounting conveyor systems, storage racks, and heavy equipment in factories.
- Infrastructure: Anchoring highway guardrails, bridge components, and traffic signals.
- Marine/Aquatic: Fixing docks, piers, and offshore platforms (316 stainless steel options).
- Expansion Mechanism: Wedge design creates a secure, permanent bond without adhesives.
- Vibration Resistance: Ideal for dynamic loads in machinery or seismic zones.
- Corrosion Protection:
- Hot-dip galvanized (HDG): 1,000+ hours salt spray (ASTM B117).
- 316 stainless steel: 2,000+ hours salt spray for extreme environments.
- Temperature Tolerance: -40°C to +400°C (alloy steel Grade B7 for high-temperature applications).
- Material Upgrades: 2205 duplex stainless steel for ultra-high strength and corrosion resistance.
- Special Coatings: PTFE (anti-seize), zinc-nickel (military-grade), or color-coded finishes.
- Bespoke Sizes: Oversized diameters (M48+), extended shanks, or metric-imperial hybrid threads.
- Engineering Support: Free design calculations and CAD drawings for complex projects.
- Quality Assurance: Material test reports (MTC) and proof load certificates available upon request.
- Sustainability: Recyclable steel options and low-carbon manufacturing processes.
