metalframed

Metalframed is an adjective describing objects or structures that employ a frame made primarily of metal. The term is used across several industries, including architecture, furniture, eyewear, and transportation, to distinguish metal skeletons from wooden, plastic, or composite frames. A metal frame provides rigidity, strength, and durability, and often enables slender profiles and modular design.

Materials commonly used for metal frames include steel, aluminum alloys, and titanium. Fabrication methods include welding, brazing, riveting, and bolting, with joints selected to balance strength, repairability, and cost. Protective finishes such as galvanizing, powder coating, or electroplating extend service life by resisting corrosion. In some assemblies, metal frames are combined with nonmetal components, relying on mechanical fasteners or adhesives rather than fully welded joints.

Applications are diverse. In architecture, steel- or aluminum-framed buildings use a metal skeleton to support floors and walls. In windows and doors, metal frames offer durability and thin sightlines. In transportation, metal frames underpin bicycles, motorcycles, and automotive chassis. In eyewear, metal-framed glasses provide adjustable fit and durability. In furniture and equipment enclosures, metal frames deliver rigidity and heat dissipation.

Advantages include high strength-to-weight ratio, long service life, and ease of repair or modification. Disadvantages can include susceptibility to corrosion without protective treatment, higher cost than some alternatives, weight for certain alloys, and thermal expansion mismatches with nonmetal components.

Maintenance involves inspecting for corrosion, ensuring fasteners remain tight, reapplying protective coatings as needed, and replacing worn joints or fasteners.
