How Long Can You Use A Corrugated Metal Raised Garden Bed?

Corrugated metal raised garden beds are becoming more and more popular because of their durability and durable design. They look great and can keep your garden elevated, but they are not without disadvantages. If you are considering purchasing a metal raised garden bed, it is important to know how long it can be used and when it needs to be replaced.

The corrugated metal raised garden bed has a service life of up to 60 years. Most of these beds can be used for at least 30 years, making them more durable than wooden raised garden beds. Adding cedar support to all four corners makes the bed more durable. It is also important to install support beams outside the metal.

In this article, we will discuss how long corrugated metal raised garden beds should last, how to make your raised garden beds last longer, and whether they are pressure resistant, UV, water, etc.

How many years can a corrugated metal raised garden bed last?

It is estimated that the corrugated metal bed should last for three to 60 years before the beginning of some degree of degradation, and the realistic schedule may be close to 20 years. Proper structural support is critical to making the most of these pots.

They can not only prevent accidental soil movement, but also prevent damage caused by earthquakes, strong winds and other natural disasters.

How to prolong the service life of corrugated metal bed

To prolong the service life of the corrugated metal bed, please follow the steps below:

  1. Balance the ph value of soil as much as possible. Mike's backyard garden explained that acidic soil corrodes corrugated metals (if metals are exposed to extremely low ph soils and plants, it won't last too long. Add neutral soil and garden water to maintain a healthy soil ph if it becomes too low.
  2. Keep the soil more moist than usual. The corrugated metal bed absorbs heat. Reflective metal absorbs some heat and transfers it to the soil. This means that your garden can dry faster than a wooden garden bed.
  3. Avoid using plastic lining. The plastic lining can prevent weeds from passing through the metal bed, but it can also cause rust. If your metal bed gets rusty due to poor drainage of the plastic layer, it will fall apart in a few years. Instead, consider landscape fabrics or aerate the soil beforehand.
  4. Clean the bed once a few weeks. Spray and dry the outside of the corrugated metal bed to remove rust, dirt and grime. If you prevent these problems from getting out of control, they will not deteriorate the metal. In addition, cleaning the bed can prevent spiders and other insects from entering the raised garden.

Garden beds are designed to cope with heat, moisture and wind from local weather conditions. However, you can use the above tips to extend the service life of the corrugated metal bed by several years. These suggestions can not only prevent rust and corrosion, but also prevent the bed from collapsing.

Is the corrugated overhead metal bed elastic?

The corrugated metal raised garden bed has the elasticity of resisting heat, excessive weight distribution and pressure. This metal is very flexible and strong, which means it is not as easy to crack as plastic. In addition, corrugated metal can withstand direct pressure, including countless pounds of soil and plant pressure.

This is why corrugated metal raised garden beds last longer than most garden beds:

  • They do not experience wood decay. Wooden elevated garden beds can cause termites, wood decay and other problems. However, corrugated metals are elastic and do not experience the same problems as wood. In addition, it can absorb moisture rather than soak it and swell or crack it.
  • These beds are very flexible and do not bend permanently. The soil in a raised garden bed can weigh hundreds of pounds. This weight can separate the weak metal, but the corrugated metal will move with the movement of the soil. The corrugated design provides natural structural support for many years to come.
  • They will not break or break due to uneven weight distribution. If you use a lot of rock or soil in the bed to move in one direction accidentally, you don't have to worry about the corrugated metal bed breaking or fragmentation. The wood is broken, but the corrugated metal is durable and durable.
  • Corrugated metal beds can limit bacterial growth. Zinc is found in most corrugated metals and naturally kills many bacteria. In addition, unlike wooden beds, metals cannot absorb moisture. The antibacterial properties of zinc can prevent bacteria from spreading to the soil edge.
  • They can withstand considerable heat. These beds reflect a lot of the sun's ultraviolet rays. The heat absorbed is transferred to the soil, thus preventing the metal from cracking or cracking due to temperature rise. In addition, metal has higher temperature resistance than most other garden bed materials.

Undoubtedly, corrugated metal beds can be used for decades. Cleaning and maintaining beds will also extend their service life. These beds take longer to create and place, but most gardeners find them worth the time and effort.
