U-Bolt Finishes for Industrial Strength & Corrosion Resistance
At Dale Fastener Supply, we recognize the critical role U-bolts play in securing oil & gas infrastructure, chemical processing systems, and construction projects. To ensure maximum performance, longevity, and protection, we offer a wide range of industrial-grade finishes, engineered to enhance durability and corrosion resistance in high-stress environments.
Premium Coatings for U-Bolts
Plain Finish: Cost-Effective Protection
Our plain finish U-bolts are coated with oil to prevent rust during storage and transport. Ideal for low-corrosion environments, they serve as a cost-effective option for applications not exposed to extreme conditions.
For enhanced corrosion resistance, we offer plain finish U-bolts in 304 and 316 stainless steel, perfect for moisture-prone and chemically exposed settings such as:
- Water treatment facilities
- Food processing plants
- Pharmaceutical and sanitary applications
Zinc-Plated: General-Purpose Oxidation Resistance
Through an electroplating process, a thin layer of zinc is bonded to the steel surface, acting as a sacrificial layer that protects the underlying metal from rust. This finish is best suited for indoor applications where exposure to moisture and chemicals is limited.
Ideal for:
- HVAC systems
- Light-duty industrial settings
- General construction applications
- Hot-Dip Galvanized (HDG): Long-Lasting Outdoor Protection
Hot-dip galvanizing involves submerging U-bolts into molten zinc, creating a thick, durable zinc-iron alloy that forms a robust barrier against corrosion. This process ensures longevity, even in highly corrosive environments, including:
- Coastal areas & marine applications
- Infrastructure projects & bridges
- Heavy-duty industrial & construction sites
Xylan® (PTFE Teflon® Blue): Ultra-Low Friction & Chemical Resistance
Xylan coatings utilize fluoropolymer technology, incorporating PTFE (Teflon®) for a non-stick, low-friction surface. This finish reduces galling and improves torque consistency, making it an essential choice for oil & gas operations with hydrocarbon and abrasive substance exposure.
Designed for:
- Extreme industrial environments
- High-stress fastening applications
- Oil & gas pipelines and equipment
SermaGard®: Engineered for Toughest Industrial Challenges
SermaGard® coatings offer dual-layer corrosion protection, featuring a zinc-rich base coat with an advanced topcoat for extreme resistance to abrasion, chemicals, and environmental exposure. Applied through precision spraying and heat curing, this finish ensures maximum durability.
Perfect for:
- Chemical processing plants
- Oil refineries
- Heavy-duty construction projects
