Terneplate is a specialized type of sheet metal product used primarily in the construction industry. It refers to a sheet of steel that has been coated with a mixture of lead and tin, which provides it with enhanced resistance against corrosion and rusting. The term "terneplate" itself is derived from the Latin word "terna," meaning "threefold," indicating the three-layered composition of the metal.
The process of creating terneplate involves immersing the steel sheet in a bath of molten lead, followed by a topcoat of tin. This dual coating creates a protective barrier that prevents the steel from coming into direct contact with moisture or atmospheric elements, effectively reducing the risk of oxidization and degradation over time. The resulting terneplate exhibits a characteristic dull gray appearance, distinguishing it from other types of coated steel.
Due to its exceptional corrosion resistance, terneplate finds widespread application in outdoor construction projects, particularly for roofing and siding purposes. It is especially preferred in areas with high levels of humidity or exposure to saltwater, where conventional steel sheets are prone to deterioration. Additionally, terneplate's malleability allows it to be easily formed and shaped into various architectural designs, making it a versatile choice in construction applications.
In summary, terneplate is a type of sheet metal coated with layers of lead and tin that provide it with enhanced resistance against corrosion. Its characteristic properties make it a popular choice in construction applications requiring durable and rust-resistant materials.
The word "Terneplate" is a compound word derived from the combination of two terms: "terne" and "plate".
The term "terne" originates from the Old French word "terne", which means "dull or dark-colored". It further comes from the Latin word "ternus", meaning "consisting of three" or "threefold". In the context of metals, "terne" historically referred to an alloy, specifically a low-grade mixture of lead and tin.
The word "plate" originates from the Old French "plate", which originally referred to a thin sheet of metal. It comes from the Late Latin "plattus" and the Greek word "plátēs", both meaning "flat, broad".
Therefore, "Terneplate" refers to a metal sheet or plate made of the alloy known as "terne".
