Zinc Aluminum Magnesium (ZAM) is a new type of coating. It is better than standard galvanizing. The coating contains zinc, aluminum, and magnesium. This combination gives it self-healing properties. If the surface gets scratched, the coating protects the exposed steel. The ZAM coating is more durable than standard zinc. Our Zinc Aluminum Magnesium C Channel lasts longer in outdoor environments.
Self-Healing Protection
The ZAM coating has a special property. It is called self-healing. If the coating is scratched, the magnesium reacts with the air. It forms a protective layer over the scratch. The steel does not rust. This is important for punched holes and cut edges. These areas are often bare steel on standard products. With ZAM, these areas are protected. The channel lasts much longer in wet, salty, and corrosive environments.
Available in All Standard Sizes
The Zinc Aluminum Magnesium C Channel is available in all standard sizes. 41x21mm, 41x41mm, 41x62mm, and 41x72mm are available. Larger sizes are also available. The wall thickness ranges from 2.0mm to 3.0mm. The standard length is 6000mm. We can cut to any length. The channel has pre-punched holes. The holes are 50mm apart. All hardware matches the ZAM coating. Our 2-year warranty covers everything. This is the premium choice for demanding outdoor projects.
