What are metal raised garden beds made of?

Generally made of galvanized steel or aluminum-zinc steel.

Our garden beds are made of aluminized magnesium zinc steel.

What is Galvanized Steel?

Galvanizing is the process of bonding a layer of zinc to the surface of steel or other ferrous metals such as iron. This process prevents steel or iron from rusting when in contact with water. Most galvanized steel is made by a hot dip process. The steel sheet, whether corrugated or smooth, will be completely immersed in molten zinc. This will create an even coating on the steel surface. Sometimes the metal is cooled to allow the material to fully bond and then re-immersed in a secondary coating.

What is Aluminium Magnesium Zinc Steel?

Aluminum-magnesium-zinc steel sheet is a new type of high corrosion-resistant coated steel sheet. Its galvanized layer is mainly composed of zinc, which consists of zinc plus 11% aluminum, 3% magnesium and trace silicon. 9.00mm, can produce a width range of 580mm-1524mm.

Due to the compound action of these added elements, the corrosion inhibition effect is further improved. In addition, it has excellent machinability under harsh conditions (stretching stamping, bending, paint welding, etc.), with high coating hardness and excellent damage resistance. Compared with ordinary galvanized and galvanized products, better corrosion resistance can be achieved with less adhesion. Due to this super corrosion resistance, it can be used instead of stainless steel or aluminum in some fields. The anti-corrosion and self-healing effect of the cutting end face is a major feature of this product.

Are metal raised garden beds safe?

Yes, galvanized metal raised garden beds are becoming one of the most popular garden beds. They're durable, strong, damage-resistant, won't rot like wood, and last for decades; the zinc coating is safe enough for livestock keeping and watering. Zinc is an essential micronutrient for plants and a normal part of soil, and it is unlikely to seep into food, so they are also completely safe for plants.

Benefits of Metal Raised Garden Beds

A metal garden bed doesn't expand or contract, doesn't require oil or paint to maintain it, and can take whatever nature throws at it. Shallow metal raised garden beds are easily filled with your preferred pH-neutral, well-drained soil, however, darker metal raised garden beds may require more filling material. Metal raised garden beds are great against cold and heat, most metals get hot in the sun, but moist soil is an amazing coolant for hot metals, so your garden or pots won't get too hot, especially Yes if you have been watering. Because the metal can transfer some heat, the soil on the sides of the metal garden bed may be warmer than the center. This is actually a good thing, especially in the spring when the soil in metal garden beds heats up faster than the ground, allowing you to start your garden earlier. Metal raised garden beds are easy to assemble and can be installed quickly.

How do you protect your metal garden bed?

Galvanized steel is a sturdy material that can withstand most garden uses. But there are ways to make sure your metal garden beds are safe for decades to come! That said, avoid using fresh chicken manure on metal garden beds. As amazing as it is, its acidity breaks down the zinc surface faster, putting the steel at risk of rusting. Instead, use composted chicken manure or other organic fertilizers to choose plants that will grow in neutral soil and keep the pH of the soil on the neutral side. At neutral levels, zinc is less likely to break down into the soil. If you're growing acid-loving plants, consider using a plastic lining. Plastic can keep acidic soil from coming into direct contact with metal, as long as it only covers the sides and doesn't interfere with the drainage of metal raised garden beds.
