The drawings below represent standard extrusions that are specifically sized and engineered so that the correct balance of product weight, strength and cost can be taken into account during the design process. The channel inside the tubing allows for fabric to stapled to the frame while the flanges are typically used to hold sheeting material like egg crate. These extrusions are typically available in either aluminum or galvanized steel.
