🧪 How long can your stud bolt coating resist corrosion?
Not all coatings offer the same level of protection. Choosing the right coating can significantly improve the service life of your fasteners in demanding environments.
Here's a comparison of the typical ASTM B117 Salt Spray Test performance of different coatings: ✔ Black Oxide ✔ Zinc Plating ✔ Hot Dip Galvanizing (HDG) ✔ Geomet® ✔ Xylan® 1070 ✔ Xylar® 2 + Xylan® 1424
At Rotex Engineers, we help customers select the most suitable coating for their application, ensuring reliable performance in Oil & Gas, Petrochemical, Power, Marine, Chemical and Infrastructure industries.
