SHEET METAL PRODUCTION

Cofan’s sheet metal is a form of metal fabricated into thin, flat pieces and is a fundamental material in metalworking. It is available in various thicknesses, from very thin foils to thicker plates. Sheet metal is made from different materials, including steel, aluminum, copper, brass, and tin, each offering unique properties suitable for various applications.
Common types of sheet metal include cold rolled steel, which has a smooth finish and tight tolerances and is often used in precision applications; hot rolled steel, which is generally cheaper and used in construction; galvanized steel, coated with zinc to prevent rusting and used in outdoor and corrosive environments; and stainless steel, known for its resistance to rust and staining, commonly used in kitchen appliances, medical equipment, and structures.
Cofan’s sheet metal finds applications in numerous industries, such as automotive and aerospace, where it is used for body panels, engine components, and structural elements; construction, where it is used for roofing, siding, ductwork, and structural frames; consumer goods, including appliances, electronic enclosures, and packaging; industrial applications like machinery, equipment housings, and HVAC systems; and art and design, where it is used for sculpture, decorative panels, and furniture.
Fabrication techniques for sheet metal include cutting (shearing, laser cutting, water jet cutting, and plasma cutting), bending (using press brakes, roll forming, and stamping), punching (creating holes or shapes with a punch press), forming (shaping metal into desired forms through deep drawing, spinning, and roll forming), and joining (welding, riveting, and adhesive bonding).
The advantages of sheet metal are its versatility, allowing it to be easily shaped and customized for various uses; its strength and durability, providing structural integrity while remaining relatively lightweight; its cost-effectiveness due to efficient manufacturing processes and wide material availability; and its recyclability, making it environmentally friendly. Sheet metal is crucial in modern manufacturing and construction, offering flexibility, strength, and efficiency across a wide range of applications.
