Galvanized Steel vs Galvanized Steel: Which Material Is Better For Raised Garden Beds
About Aluminum Zinc Steel

Compared with ordinary galvanized steel, galvanized steel is a super material. Aluzinc is a coating material formed from a mixture of aluminum (55%), zinc (43.4%) and silicon (1.6%). Durable to provide excellent performance and corrosion resistance in all environmental conditions.

Galvanized steel is an ideal material for outdoor use. In Scandinavia, outdoor exposure testing has been done for almost 20 years. They demonstrated that the corrosion rate of Aluzinc is 3-7 times lower than that of ordinary galvanized steel

Corrosion time is 3 times longer in rural environment

Corrosion time is 4 times longer in urban environment

Corrosion time is 4 times longer in marine environment

Corrosion time is 7 times longer in industrial environment

5 benefits of using aluminum-zinc steel for nosstagarden raised garden beds

Extremely strong corrosion resistance: Compared with wooden or plastic beds, Aluzinc’s corrosion and rust resistance is 7 times that of ordinary galvanized steel, and 3-7 times that of ordinary galvanized steel. Corrosion rate (under normal conditions The annual loss of Aluzinc coating thickness) is a maximum of 20% of one micron (0.2 microns). Theoretically, Aluzinc has a service life of more than 100 years under normal conditions. In real life, Aluzinc has been used in the harsh marine environment for more than 20 years, despite the coating loss of up to 0.4μm in the first year.

Excellent heat reflection: Aluzinc steel has excellent albedo capabilities. Albedo, another name for reflectivity, measures how much light that hits a surface is reflected rather than absorbed. Studies have shown that soil in galvanized steel maintains an optimal and more uniform temperature, absorbing summer sun during the day and retaining heat at night, compared to wood, concrete and dark plastic beds. Studies have also shown that galvanized steel beds have the added benefit of improved fruit set, rose color and ripeness.

Incredibly high strength: Aluzinc surface is twice as hard as ordinary galvanized steel, and more than 5 times harder than wood or plastic. With high abrasion resistance, Vego raised beds can hold the soil for decades without deformation.

No Soil Pollution: While treated wood and plastic degrade in extreme temperatures, Aluzinc materials do not leach chemicals into plants or soil. This helps create the best quality soil for organic gardening.

100% green and recyclable materials: Steel has a long service life and is an environmentally friendly material made with "green technology". Not only is steel 100% recyclable, it is also the most recycled material in the world.
