What is a Structural Washer?
A structural washer is a robust, heavy-duty washer commonly used in steel-to-steel connections found in buildings, bridges, towers, and other large-scale structural applications. These washers are thicker and have a larger outer diameter than standard washers, allowing them to handle high loads. They're often paired with high-strength bolts like A325 or A490 to ensure strong and reliable connections.
Key Features of a Structural Washer:
- High Strength: Made from hardened steel to withstand high tension and compression loads.
- Large Outer Diameter: Distributes load more effectively, reducing stress on materials.
- Thicker Design: Offers added durability and support in structural assemblies.
- Corrosion Resistant Coating: Often galvanized or coated for protection in outdoor or harsh environments.
- Meets Industry Standards: Manufactured in compliance with ASTM F436 or equivalent standards.
Common Uses of a Structural Washer:
- Steel frame construction
- Bridge and highway infrastructure
- Wind turbines and structural towers
- Machinery bases and heavy equipment foundations
- Industrial and commercial building frameworks
- Civil engineering and load-bearing connections
