Ohutlevyissä

Ohutlevyissä is Finnish for “in thin sheets” and refers to metal sheets with relatively small thickness used in metalworking and manufacturing. The term is commonly employed to describe materials, components, or processes where sheet metal serves as the base form, as opposed to thicker plates or extruded profiles.

Materials used in ohutlevyissä include steel, stainless steel, aluminum, copper, brass, and titanium. Typical thicknesses for thin sheet metal range roughly from 0.2 to 6 millimeters, with many commercially produced sheets falling in the 0.3 to 2.5 millimeter band. The choice of material and thickness depends on required formability, strength, weight, and cost.

Manufacturing and finishing involve rolling, often cold rolling, to achieve uniform thickness and good surface quality. After forming processes such as bending, punching, stamping, and deep drawing shape the parts. Finishing options include heat treatment, galvanizing or zinc coating for corrosion protection, and surface coatings like painting, powder coating, or anodizing (especially for aluminum) to improve appearance and durability.

Applications of ohutlevyissä are wide and include automotive body panels, enclosures for consumer electronics and home appliances, HVAC components, architectural cladding, and packaging such as tinplate and aluminum cans. The thin-sheet format enables high surface area-to-weight ratios and cost-efficient production, especially for complex shapes.

Key considerations in ohutlevyissä include formability, joinability, surface finish, and tolerances, as well as corrosion resistance provided by coatings. Recyclability is a notable advantage, contributing to sustainability in industries that rely on thin sheet metal.
