In furniture construction, metal profiles are used to support or connect wooden panels or boards. Especially in cabinets and storage cupboards with large storage capacity and few demands on aesthetics, metal profiles are often used to create a repetitive structure in which plywood particleboard or other panels can be placed. They are ideal for demountable and adjustable furniture.

Metal profiles exist of a tube or have a L-shaped section in order to form a stable structure. They are provided with holes at regular distances to make connections between profiles in various places. Metal profiles are usually made of aluminium, galvanized steel or stainless steel.
