metallplater

Metallplater, or metal plates, are flat, rectangular pieces of metal produced by rolling slabs or extruding billets. They are typically thicker than metal sheets and are used in applications where rigidity, strength, or load-bearing capacity is important. Plate materials span carbon and alloy steels, stainless steels, aluminum, copper, brass, bronze, nickel, and titanium, among others. Common plate forms include hot-rolled, cold-rolled, and specialty plates such as galvanised or clad varieties.

Manufacturing processes: Hot-rolled plates are formed at elevated temperatures and then cooled, yielding tough, ductile material with a rough surface. Cold-rolled plates are further processed at room temperature to achieve tighter tolerances and smoother finishes. Finishes range from mill rough to brushed, satin, matte, or mirror, and may include protective coatings or surface treatments to improve corrosion resistance or wear properties.

Properties and selection: Plate thickness ranges from less than a millimeter in some alloy families to several centimeters in heavy structural applications. Important properties include strength, hardness, ductility, toughness, corrosion resistance, and weldability. Selection depends on service conditions such as temperature, environment, mechanical loads, and fabrication method. Considerations also include allowable tolerances, surface finish, and any required heat treatment or finishing.

Applications: Metal plates are used in construction and infrastructure, shipbuilding, automotive and heavy equipment, pressure vessels, machinery housings, flooring, and as base or structural components in fabricated assemblies. They can be machined, formed, drilled, cut via plasma or laser, and welded as part of larger structures.

Standards and availability: Plates are specified by grade, thickness, width, and length, with material standards such as ASTM/SAE, EN, or JIS. They are widely available from metal suppliers and distributors and are often recycled at the end of life.
