There are three types of sawhorse: one is Woods, the second one is Plastic, and the third one is heavy-duty metal.
Wood made sawhorse is heavier than others. So this is not so popular nowadays. But wood made sawhorse is durable and holds a high weight capacity.
Plastic made sawhorse is lightweight and it is the perfect choice for lightweight projects such as cutting plywood and painting. This is a foldable sawhorse for easy storage and transportation. And some of the plastic made sawhorse includes the shelf to keep your material.
Heavy-duty metal made sawhorse is a better quality sawhorse but it is not perfect for outdoor.
