Stainless steel offers long-term corrosion resistance in tough environments, such as coastal areas and places where moisture may accumulate. However, stainless steel is not always effective when fastened to certain dissimilar types of metal — resulting in galvanic corrosion.

To prevent this, Alloy Fasteners offers AllFlex fasteners, which are coated with a Stalgard GB (Galvanic Barrier) finish. Stalgard GB provides far greater galvanic protection for aluminum components than standard (300 series) stainless steel fasteners.

AllFlex stainless steel thread cutting and self-tapping fasteners are ‘Made in the USA,’ and have a proven success record in architectural applications. They’re an ideal fastening solution for curtain walls, windows, doors and other applications that include a dissimilar metals, such as aluminum.

Stainless steel coupled with the Stalgard GB coating gives AllFlex can provide superior protection in the harshest environments.
