Metals in construction

Metals in construction:

• Aluminum is a silvery white metal, lekki, malleable, fusible, well conductive to heat and electricity, corrosion resistant. In construction, it is used to make construction elements (aluminum profiles) windows, door, winter gardens, fireflies, canopies and protective films and coatings.

• Zinc is a bluish-silver metal. Oxide film, generated on its surface protects it against weather conditions. It is used in the manufacture of zinc sheets, production of protective coatings (protecting steel against corrosion), production of zinc paints. It is part of many metal alloys (e.g. brass, bronze).

• Copper is a metal with a characteristic red sheen, malleable and malleable, conducts heat and electricity very well. Under the influence of moisture, it becomes covered with a green bloom called patina. Roofing sheets are made of copper, gutters and downspouts, pipes for water and central heating installations.

• Brass is an alloy of copper with zinc and the addition of other metals (5-6%): lead, iron, manganese. Brass conducts heat and electricity well, it is resistant to corrosion, easy to process. It is used in the manufacture of construction fittings, sheets, pipes, screws, ornaments.

• Bronze is an alloy of copper and tin, sometimes with an admixture of another metal, e.g. aluminium. It is used in the manufacture of decorative elements: times, railings, handrail.

• Bronze is a copper alloy, tin, zinc and lead. It is a wear-resistant metal. It is used for the production of decorative elements.

• Nickel is a silvery white metal, hard, malleable, hardly fusible, resistant to oxygen, moisture, air. It is used to coat other metals (steel, zinc, copper) to increase their strength and corrosion resistance. It is a component of many alloys (e.g. brass).
