Premium Materials

non-toxic garden bed material for growing food at home
ZAM Steel refers to Zinc-Aluminum-Magnesium alloy coated steel, an innovative steel finish that is exceptionally different than other steel treatments.

This amazing steel product is created by hot-dipping steel substrate in a proprietary coating of Zinc, Aluminum, and about 3% Magnesium. Compared to other advanced steel coatings such as Aluzinc, ZAM coating have remarkably superior performance in extreme environment (especially in agricultural and coastal applications). What also set ZAM coating apart from the rest is its unique self-healing characteristics. Zinc and Magnesium in the coating work in synergy to form a dense protective film on the metal cut edge, sealing and protecting the exposed steel substrate from corrosion.

Our food-safe, USDA Certified paint from AkzoNobel is specially formulated for the farming industry, designed to withstand harsh environments, and provides excellent protection against elements.

What are the advantages of ZAM Steel compared to other materials?

Exceptional Corrosion Resistance & Superior Durability: ZAM Steel is 7 times more durable compared to wooden or plastic garden beds. It also outperforms regular galvanized coating by 2-6 times with its superior long-term corrosion resistance. With ZAM Steel’s low corrosion rate, GROBOX garden beds are built to last more than 20 years in extreme environments.

No Toxic Leaching or Soil Contamination: Unlike treated wood or plastic, ZAM Steel will not degrade under extreme temperatures, and will not leach toxic chemicals into your soil or contaminate your plants. Safe for organic gardening, GROBOX garden beds give you peace of mind when growing your own food.

100% Recyclable & Eco-friendly: ZAM Steel is an environmentally-friendly material manufactured using green practices. As the world’s most recycled material, steel shines with its 100% recyclability. You will enjoy a long useful life on your GROBOX garden beds with its superior durability. By choosing a long-lasting product, you also help reduce environmental costs from replacing short-lived garden beds.

Excellent Strength: ZAM Steel’s surface is 5x harder compared to wood or plastic, and 2x harder compared to regular galvanized steel. The high-strength profile of ZAM Steel makes GROBOX garden beds more resistant to wear and tear.

Advanced Heat Reflectivity: ZAM Steel has a higher albedo capacity, which means it absorbs less heat under the hot summer sun. It keeps the soil at more even temperatures compared to other garden bed materials such as wood, concrete, or dark plastic.
