Why You Need to Choose the Best Metal Runner Bean Frame

Reliable and easy to grow, it’s no wonder that beans are a favorite amongst home gardeners! However, some varieties can grow well over head height and require the support of a metal runner bean frame or trellis to keep them upright, ensuring healthy growth. Today, I’ll go over two of the best climbing bean frames on the market: TinkTube and Agriframes, evaluating their features, benefits, and suitability for different gardening needs.

Whether you’re a DIY seeker or looking for a well-designed, done-for-you option, there’s something for everyone here.

So, without further ado, let’s get started!

Metal Garden Frames vs Wooden Garden Frames

Garden frames can take many forms and be constructed from different materials. But when the situation calls for a heavy-duty runner bean growing frame, metal and wood are the most popular options.

This is primarily due to their unmatched durability and sturdiness. When built and appropriately protected, they can withstand all kinds of weather, supporting your climbing crops all year round. With that being said, here’s a quick rundown of metal vs. wooden garden frames.

Metal Garden Frames

Whether aluminium, iron, or stainless steel, metal garden frames are a reliable choice as a long-term trellis solution. Their ornate design adds a touch of stylish charm wherever they’re used.

On the flip side, these frames tend to be heavier on the pocket and may conduct heat during extremely hot temperatures (which could potentially harm your plants).

Metal garden frames are the toughest and sturdiest option available and can hold plenty of weight.Metal frames can rust in contact with humidity if not protected or painted properly
Can be treated or painted to resist rust and corrosion so will last for many yearsCan be more expensive
Boasts a sleek, beautiful finishSome gardeners prefer the natural look of wood to metal
Folding construction of some models makes for easy assembly and storage.

Wooden Garden Frames

Wooden garden frames are an affordable and more basic option for home gardeners. From bamboo poles to wooden stakes, these supports come in many varieties and usually be moved anywhere.

The main downside is if you’re not using treated wood, they can quickly rot and only last a season or two. And treated wood has its downsides when it comes to chemicals potentially leaching into the soil.

Simple to work with and can be cut to your preferred sizeThe lighter weight of these frames makes them more vulnerable to storms and winds.
