If you’re an avid gardener, you’re almost certainly familiar with growing plants in raised beds. The method gives you more control over your soil composition and helps with pest control, among many other benefits. Choosing the right raised bed materials is, however, not without its fair share of bother. Which material is strongest and, perhaps more importantly, safest for your plants? One popular option, galvanized steel, can be a bit controversial due to the metal’s zinc coating.
種植蔬菜需要比觀賞植物更多的照護，因為你要確保它們是可以安全食用的。概括來說，在家庭花園中使用鍍鋅鋼是可以放心的。當鋼材被鍍鋅時，其表面會覆蓋一層鋅塗層。這層塗層使鋼材更耐鏽，在潮濕土壤充足的露天花床上顯得尤為有用。
典型的鍍鋅鋼板在每面大約有 20 微米厚的鋅塗層。在這個厚度下，鋅在大多數情況下是無害的。如果塗層被刮傷、土壤酸鹼度過高，或土壤長期潮濕，鋅可能會更容易滲出。然而，即使在這些情況下，鋅造成對蔬菜或食用者的傷害的可能性仍然較低。使用鍍鋅鋼，你可以快速開始一個蔬菜花園，並且組裝床架相對簡易，預計至少可使用幾十年。
Selecting and caring for a galvanized steel garden bed

As you can see, these kits are relatively affordable, especially when you consider how long they last.
