* A mesh skin graft is a skin patch that has been cut systematically to create a mesh. Meshing of skin grafts provides coverage of a greater surface area at the recipient site, and also allows for the egress of serous or sanguinous fluid. However, it results in a rather pebbled appearance upon healing that may ultimately look less aesthetically pleasing. *Fiberglass mesh is a neatly woven, crisscross pattern of fiberglass thread that can be used to create new products such as door screens, filtration components, and reinforced adhesive tapes. It is commonly sprayed with a PVC coating to make it stronger, last longer, and to prevent skin irritation. *Coiled wire fabric is a type of mesh that is constructed by interlocking metal wire coils via a simple corkscrew method. The resulting spirals are then woven together to create a flexible metal fabric panel. Coiled wire fabric mesh is a product that is used by architects to design commercial and residential structures. It is also used in industrial settings to protect personnel and contain debris. Additionally, coiled wire fabric mesh is used for zoo enclosures, typically aviary and small mammal exhibits. >The Art of Coiled Wire Fabric: Flexibility and form on a large scale
