Galvanized steel is considered safe for use in garden beds. This material offers high resistance to rust, provides impressive durability, and proves beneficial to plant growth. Notably, galvanized steel can withstand varying weather conditions, retaining its structural integrity for many years, which is especially important for garden beds exposed to outdoor elements. Galvanized raised beds represent an excellent choice, promising longevity and reliability while contributing positively to a garden’s vitality.

Is It Safe To Use Vegega Galvanized Raised Beds?

The answer is yes. Vegega metal raised garden beds are safe for use. With the development of technology, more and more gardening tools are designed to simplify garden work. Galvanized steel garden beds is a novel garden bed in gardening. And more gardeners will consider using a metal garden bed to grow plants. Not just for the eco-friendly, but for fewer garden tasks.

Metal raised garden beds are undoubtedly a very safe product for all people. Vegega has done many test to show the non-toxic result. Every aspect of the product, from the material to the accessories to the planting, is safe to use. For the outer, Vegega uses AkzoNobel paints for the coating. For the metal panels, Vegega uses Zn-Al-Mg steel panels, which are super corrosion resistant. And combine the two materials, Vegega modular corrugated metal raised garden beds can last at least for 20 years with no maintenance and replacement required.

Vegega galvanized raised beds have no sharp corners because the rubber strips are provided to ensure that no cuts will occur. So the metal bed is suitable for all people to use in all ages.

For garden bed deformation issues, some metal garden beds will bend out after filling. That's because the garden bed does not install bracing rods. Vegega 6-in-1 and 9-in-1 series garden beds are equipped with bracing rods to avoid this issue. For most metal garden beds, if you take scientific methods to fill the garden bed like hugelkultur method, this situation won't show up.

Vegega galvanized garden beds test certificates

Vegega has gain USDA paint warranty, ISO-9001 non-toxic and eco-friendly report, AkzoNobel food-contact coat certificate, SGS safe steel report, and a certificate for 30 years warranty for steel structure. More details in the following pictures:

1. Coating safety

100% non-toxic, eco-friendly materials

Vegega uses AkzoNobel paint, the leading brand of 100% non-toxic paint, which is uniformly thick and free of crusts, impurities, and particles. This ensures metal raised garden beds have smooth and grain-free panels. Even after long exposure to the sun, the coating will not crack and peel off. Vegega metal raised garden beds have received dual USDA certification in the United States and Canada.

Environmentally friendly

Both the coating and the material used in the metal garden beds are eco-friendly. It meets the RoHS standard of the European Union and is now an internationally recognized environmentally friendly product. The coating does not contain heavy metal ions and can be planted with confidence.

2. Material safety of galvanized steel garden beds

Zn-Al-Mg Stainless Steel

Vegega products are made of Zn-Al-Mg Steel, which has superior corrosion resistance, abrasion resistance, heat resistance, scratch resistance, rust resistance, etc. More information in article: Zn-Al-Mg Steel vs. Aluzinc Steel.

The Zn-Al-Mg alloy coating is made of zinc (Zn), aluminum (Al) and magnesium (Mg) cured at a high temperature to form a dense ternary eutectic structure, resulting in a dense, super coating that effectively prevents corrosion on the surface of the steel sheet.

【Upgrade 2.0】Side Panels To Extend 17"Tall Metal Raised Garden Beds -2 Pcs

$43.95

Size

If the metal garden bed size still doesn't meet your needs and you are looking for a larger garden bed to match your garden, the straight corrugated metal panels can be very convenient to extend the planting range of 17" and 32" garden beds. 

Choosing durable straight metal sheet for your raised bed

The straight metal garden panels are the same material as all Vegega Zn-Al-Mg steel garden beds. It is strong enough, stable, and corrosion-resistant to last 20 years without maintenance. 

In addition, when you increase the length of your garden sheet by 3ft (2 sets of expansion boards), it is best to buy an additional set of corresponding support rods.

  • Strong and Long-Lasting

Zn-Al-Mg steel (What is Zn-Al-Mg Steel?) made for metal garden panels 24-gauge steel is strong, lasting 4-7x longer than standard wooden raised beds.corrugated metal panels

  • Easy to Assemble

For easy assembly, those kits offer bolts, nuts, washers, wrenches, and an instruction manual. Keep the metal garden panels sturdy and free from bowing. We also offer duty rubber edging to cover the edges, providing protection from injury.

  • Rust and Corrosion Resistant

Zn-Al-Mg is more effective against rust and corrosion than standard galvanized coatings.

Metal Panels: No Contamination Worry

Unlike low-grade plastic, chemically treated wood, or poorly manufactured copycats, Aluzinc-magnesium galvanized steel does not leach or break down in any major way over time, so these beds are absolutely safe to grow food in. 

Our corrugated metal panels have adopted AkzoNobel sustainable special paint(also obtained USDA certification) developed for animal husbandry and planting, which will not penetrate into the soil. Your garden and soil are safe to go. However, most of the traditional wooden raised garden beds will add chemical preservatives in order to avoid crumbling easily, these may penetrate into the soil and do some damage to the soil.

Environmentally Friendly

Traditional wooden raised beds aren’t always a sustainable option. Research showed that roughly 15.3 billion trees are cut down each year, and logging is a big part of that. Purchasing wood for raised beds might not be an environmentally conscious decision.

Compared to wooden raised beds, our corrugated metal panels are an ideal material for any outdoor applications. It’s eco-friendly, long-lasting, and sturdy, lasting up to 20 years without needing replacement and with minimal maintenance.

Performance advantages

The performance of Zn-Al-Zn and Aluzinc steel panels cannot be compared with that of Zn-Al-Mg panels. Compared to galvanized sheet, the service life of Zn-Al-Mg is 10–20 times longer than that of galvanized sheet under the same coating condition.

Cut maintenance

This is a unique property that only Zn-Al-Mg stainless steel sheet has. Many galvanized and aluminized sheets rust gradually at the edges.

The edge of Zn-Al-Mg sheet has a notch maintenance function to ensure that the edge will not rust easily. The plating components on the surface dissolve continuously to form a dense protective film consisting mainly of zinc hydroxide, alkaline zinc chloride, magnesium hydroxide, etc. This protective film has a significant inhibiting effect on the corrosion of the cut surface. Therefore, we don't need to worry about the edge rusting.

3. Shape safety

Vegega galvanized steel garden beds set includes enough accessories for you.

Rubber edge strip

Each metal raised garden beds kit includes a strip that is long enough to be installed on the top edge of the garden bed. The panel's thickness is 0.6 mm, and its edges and corners are not sharp enough to hurt people while not taking up planting space. With the secondary protection of the rubber strips, both the elderly and children can use this planter bed to plant safely.

Bracing rod

Vegega's 17" and 32" 6-in-1 and 9-in-1 configurations come with bracing rods, which are made of magnesium-aluminum alloy and are so resistant to corrosion that they can be said to outlast metal panels. The purpose of using bracing rods is to prevent the bed from bending due to excessive soil filling. Of course, in addition to the bracing rods, which can solve this problem, another way is to fill the bed with more organic material like mulch, wood, or compost instead of all soil.

Fastener

Vegega fasteners

Each Vegega garden bed kits come with two extra sets of stainless steel fasteners, which are highly resistant to corrosion and oxidation. Moreover, the use of the washer increases the stability between the screw and the nut, and there will be no shaking when connecting two metal panels. Vegega's metal garden beds have relatively few screw holes, which saves labor and makes the beds stronger and less bent.

4. Planting safety

Metal raised garden beds are the new trend in modern gardening. First, the use of metal garden beds effectively reduces weed growth and stops pest infestation. Second, metal raised garden beds have good thermal conductivity. You can plant earlier in the spring and later in the fall to keep your garden green all season long. In the summer, the garden bed dissipates heat more quickly, effectively cooling the roots.

Third, corrugated metal raised garden beds can be used for at least 20 years. Compared to wooden garden beds, metal garden beds last longer and the material is more environmentally friendly. Using the metal garden bed all year round does not require long-term maintenance.

  • Soil safety: As we all know, the soil planted on the ground tends to dry out, lose nutrients, and even breed bacteria, which greatly reduces the quality of the soil. In contrast, soil in raised beds is kept away from the ground, effectively reducing water loss, increasing air circulation, and providing better drainage, thus building a good soil environment for plant growth, which in turn increases yields.
  • Filler safety: Raised beds effectively create nutrient-rich beds. In addition to the necessary soil, some organic matter can be used as filler. Organic matter will decompose over time, and the decomposed organic matter will continue to supply nutrients to the plant roots. 
  • Plant safety: After lining the raised garden beds, it effectively protects the root system and reduces or even prevents weeds and pests from burrowing into the garden bed from the bottom and stealing fruits.

Final Words

There is no doubt that the Vegega metal raised garden beds are 100% safe for use. If you have any questions, please email us at support@vegega.com
