Standard sucker rods are the most commonly used type. They are made of high-strength carbon or alloy steel and come in different sizes and lengths. Standard rods are typically solid, meaning they have a continuous body without hollow sections.

Fiberglass or spray metal sucker rods are used in corrosive or high-temperature environments where traditional steel sucker rods may not be suitable. Spray metal rods are coated with a layer of corrosion-resistant material, such as aluminum, to protect against chemical reactions.
