Foundation Bolts are robust fasteners designed to secure heavy machinery, columns, and structures to concrete foundations. Featuring threaded ends for nuts and washers, and various anchor designs (L-shaped, J-shaped, or headed), they are manufactured from carbon steel (Grade 5/8.8), stainless steel (304/316), or alloy steel (Grade B7) for high-tensile strength and corrosion resistance.
- Material:
- Carbon Steel (hot-dip galvanized, ASTM A307 Grade 5/8.8).
- Stainless Steel (304/316 for chemical/high-moisture environments).
- Alloy Steel (ASTM A193 Grade B7 for elevated temperatures).
- Size Range:
- Diameter: M12–M100 (metric) / 1/2"–4" (imperial).
- Length: 150–3,000 mm (customizable embedment depths).
- Design:
- Anchor Types: J-bolt, L-bolt, headed bolt (hex head or forged head).
- Thread: Full or partial threads (UNC/UNF or metric).
- Standard Carbon Steel/Galvanized: 500 pieces (in-stock sizes).
- Stainless Steel/Alloy Steel: 1,000 pieces (custom lengths available).
Factory Advantages: ISO-certified production, material test reports (MTC), support for custom anchor shapes, special coatings (e.g., epoxy, Dacromet), and bulk orders with lead times of 15–30 days.
- Construction: Securing steel columns, bridge abutments, and retaining walls.
- Industrial: Mounting generators, presses, and heavy machinery.
- Energy: Anchoring wind turbine bases, solar panel frames, and power plant equipment.
- Infrastructure: Highway signs, transmission towers, and railway components.
- High Tensile Strength: Up to 1,200 MPa for Grade B7 alloy steel.
- Corrosion Resistance:
- Hot-dip galvanized (1,000+ hours salt spray).
- 316 stainless steel for marine/chemical environments.
- Seismic Resistance: Engineered to withstand dynamic loads and vibrations.
- Non-Standard Sizes: Custom diameters, lengths, and thread pitches.
- Special Coatings: PTFE (anti-seize), zinc-aluminum (for extreme corrosion).
- Pre-Assembled Kits: Includes nuts, washers, and anchor plates.
