Is it safe to grow vegetables in modular metal garden beds?

With the increasing demands on food safety and environmental protection, more and more people choose to grow vegetables in modular metal raised garden beds, because the use of modular metal raised garden beds can achieve perfect soil quality and more Easy to prevent weeds. There are many raised garden beds on the market, wood, brick or rock, and the modular metal garden beds we mentioned in the title are becoming a new trend. An important topic here: Are modular metal garden beds safe?

I think to clarify this issue, we must first divide the "safety" issue into two: first, whether the vegetables grown in the metal flower bed are safe, or whether the metal flower bed will contaminate the soil inside; second, the impact of the metal garden bed on the surrounding Are people insecure, after all metal feels sharper than wood. Due to the limited space of this article, we will only discuss the first question, namely: Are vegetables grown in metal flower beds safe?

Modular metal garden beds on the market today are mainly made of galvanized steel sheet. This material is coated with a layer of zinc or zinc-aluminum on a cold-rolled surface. We have looked at numerous sources showing that zinc dissolves in acidic conditions. For water, garden beds made of pure galvanized steel run the risk of metal contamination of the soil within the bed. Of course, most of the soil should be neutral or neutral to alkaline. After all, animal urine, feces, etc., which are one of the natural organic fertilizers, are alkaline, so the risk of metal contamination in galvanized flower beds is very small and slow. In addition to the disadvantages mentioned above, metal garden beds made of galvanized or galvanized steel do not solve the problem of rust on the cut surface, since the cross-section is not protected by any coating during the manufacture of the metal product. As a result, galvanized metal garden beds are most prone to rust where they are cut.

Does this analysis lead to the conclusion that metal garden beds are not safe? The answer is no. After all, as technology advances, so does the technology of steel. The metal garden beds produced by our company are made of materials jointly developed with China's largest steel enterprise - China Baowu Group. This material solves the problem that the cutting surface of traditional metal products is easy to rust, and adds a color coating process. The color paint comes from the international big brand Aksu Paint. After a coat of paint, the metal garden bed is ready. Baking paint and galvanized double protection, baking paint is the first line of defense, and galvanizing is the second line of defense after painting, which not only increases the corrosion resistance of metal garden beds, but also prevents direct corrosion of galvanized by soil. This metal garden bed is more durable, strong, resistant to damage, won't rot like wood, and has a theoretical lifespan of over 30 years. It adopts special paint for animal husbandry, which has alkali resistance and meets the certification requirements of USDA in North America for indirect food contact materials. It is an ideal material for metal garden beds with acid, alkali corrosion and environmental protection requirements. Meets North American USDA certification requirements for indirect food contact materials. It is an ideal material for metal garden beds with acid, alkali corrosion and environmental protection requirements. Meets North American USDA certification requirements for indirect food contact materials. It is an ideal material for metal garden beds with acid, alkali corrosion and environmental protection requirements.

In the end we came to the conclusion that metal garden beds are a very popular raised garden bed right now and their metal properties determine that they will be much more durable than wooden garden beds. As long as we choose good steel to make metal flower beds, its safety is completely guaranteed, which is very in line with our requirements for a pollution-free vegetable growing environment.
