Know Your Rebar Before Using It In DIY Garden Projects

by Aiden Carroll

If you are like many gardeners, you may enjoy garden art, trellises and other garden structures made from rebar. What you may not know is that not all rebar is created equal. Each type of rebar performs differently, making some more suitable for your garden projects than others. Taking the time to learn about how rebar differs may mean the difference between impressive garden art and one that will rust and corrode over time.

Types of Rebar

Black Rebar

When you think of rebar, this is likely the image you conjure up in your head. Black rebar is an uncoated steel bar designed for reinforcing concrete. Black rebar will rust and corrode when exposed to the elements. If you are planning to use rebar to make a garden trellis or other garden art, be aware that uncoated rebar will not retain its sleek black beauty for long. If you prefer the weathered and worn look on your garden décor, go ahead and use uncoated rebar. This is the least expensive rebar to buy.

Epoxy Coated Rebar

Epoxy coated rebar, also called anti-corrosive rebar, is coated with epoxy to prevent the rebar from rusting or corroding over time. This rebar is designed for reinforcing cement used in marine applications or in areas where deicing is common. For use in garden projects, this epoxy coated rebar maintains its natural beauty without deteriorating or becoming covered with rust. If you are making a trellis or other DIY project where the rebar in the focal point, choose an epoxy coated rebar to keep it looking good. Epoxy coated rebar is slightly more expensive than traditional black rebar.

Galvanized Steel Rebar

Galvanized steel rebar has been coated with a layer of molten zinc that bonds to the steel. It was commonly used in applications where corrosion was an issue, but dropped in popularity when epoxy coated rebar became available. You can use galvanized rebar for you DIY garden projects, but it may lack the visual appeal you are looking for. You can find galvanized rebar in your local home improvement center.

Rebar Designs

If you are like most people, the mention of rebar probably conjures up the vision of a black rod of steel with an uneven design along the outside of the rod. But, not all rebar has a textured outside, and there is considerable variation in the texture.

  1. Plain Bars (or rods):  These rebar rods are smooth on the outside and are designed for use when the rod must slip into a sleeve to create contraction joints on bridges and highways.  While these rebar rods can be used in the garden, they may be difficult to work with, as they do not have any texture. Keep in mind that many climbing plants rely on the texture of the rebar to grip the trellis and may not perform well on smooth rebar.
  2. Deformed Bars: Deformed bars are rebar with a pattern or texture on the outside. This pattern may vary, but there are several common patterns.
  • Spiral: This rebar is formed by twisting a rod of rebar. The outside of the rebar is one continuous spiral that runs the entire length of the rod.
  • Corrugated Bars: Corrugated bars have a circular or square pattern that repeats along the length of the rebar. They are designed to adhere to concrete but can also add texture and depth to garden projects.
  • Fins: Rebar may also have longitudinal fins that run the length of the bar. These are designed to prevent the rebar from twisting when it is anchored in cement. In the garden, rebar with fins may lend unique style to your project.

Before you begin that DIY garden project with rebar, take the time to determine which kind of rebar will work best for the project. Visit your local home improvement center to browse the rebar available.
