Hot-dipped galvanized steel channels are excellent candidate for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized channels are A36 hot rolled steel, or mild steel, channels that have been dipped into a molten zinc coating process (ASTM A123). Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as “spangle” on the surface of the material. Great corrosion resistance, excellent candidate for outdoor use or exposed environments. Common applications include heating and cooling systems, walkways, ramps, structural support, trailers and electrical protection

Galvanized Steel Channel, is a A36 hot rolled, mild steel channel that has been hot dipped in a zinc rich galvanizing process. Galvanized channel is a lower cost alternative to stainless steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable hard surface coating. Metals Depot stocks many sizes in pre-cut lengths, full mill lengths or we can hot dip virtually any size and quantity required for your welding or construction project.
Galvanized channel can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated. Saw cut ends of our pre-cut lengths are not galvanized and should be treated with a cold galvanizing compound to maintain protection once your project is complete. Any holes drilled or welded areas should also be treated.
