There are three types of canopy frames
For outdoor installation, the wood must be treated and coated with protective enamel or protective wood stain. The advantage of wooden frame is soft and warm feeling. Such frame is compatible with opal and crystal green D-Lite.
It is very popular because of reasonable cost, strong, light and adaptable to many styles, but its problem is rust. It can be solved by rust-proof coating. As steel frame can be coated with every color, it is suitable for all colors of D-Lite.

This frame is durable, glossy, rust-proof with many designs, but the cost is higher than steel frame. You should cautiously select a qualified fabricator to ensure neat workmanship especially the welding seam. This frame is suitable for all colors of D-Lite as well.
