Instead of welding, structural components are attached with riveted or bolted aluminum gussets. Ribbed grosgrain may be used similarly to twill tape for internal gussets and reinforcements. Scraps are used for straps, gussets and interior details. The original Le Pelican airframe is constructed from aluminum tubing, using gussets and pop rivets. The Hornet structure is built up from aluminium tubing, riveted together with gussets. The aircraft is made from aluminum tubing that is pop riveted together using gussets. The fuselage features truss construction, with longerons and gussets and a fixed monowheel landing gear. For example, metal gussets are used in bicycle frames to add strength and rigidity. Pulleys, gussets, and splices were also included. Studs, gussets and attachment plates are located within the form for embedding in the concrete. This fills all the gussets around the cores and ensures that the cores cannot untwist. Some pantyhose have single- or double-panel gussets incorporated into them.
