Corrosion Resistant Construction Fasteners from Elco
Featuring High-Performance Stalgard® Corrosion Resistant Coatings
To meet the needs of the wide range of concrete & masonry applications in corrosive environments, Elco Construction Products has developed Stalgard®, a specialized corrosion resistant coating. Specifically designed for critical fastening applications in concrete & masonry in exposed environments, don’t take any chances, choose Elco fasteners with Stalgard® corrosion resistant coating.
What is Stalgard® Coating
Stalgard® corrosion resistant coatings are durable, multi-layer, coatings that are engineered to provide optimal performance in the most demanding construction applications. These environmentally friendly finishes are free from chromates & silicates and any process, like electroplating, that might induce hydrogen embrittlement & structural failures.
- Maximizes fastener performance
- Salt spray corrosion resistance at 1000+ hours with no red rust per ASTM B117
- Uniform thickness
- Low coefficient of friction – eliminates the need for post-coating lubricants to ease installation
- Does not use processes that introduce hydrogen – will not cause brittle failures like those caused by electroplating
- Durable tough finish – doesn’t come off during handling or repeated installations
- Eliminates the plating process, resulting in a more environmentally friendly product than those with plated zinc or other finishes
- RoHS Compliant – chrome-free
- Clean and dry – no oily residue
- Maintains drilling and tapping performance
- Blue, grey, and white Stalgard are ACQ-compatible
