plastic coated steel cladding architecture

polyvinyl chloride

flexible pvc coated wire and cable for electrical use has traditionally been stabilised with lead, but these are being replaced with calcium-zinc based systems. in a fire, pvc-coated wires can form hydrogen chloride fumes; the chlorine serves to scavenge free radicals and is the source of the material's fire retardance.

copper in architecture

copper cladding has become popular in modern architecture. the technology enables architects to incorporate visually desirable features into their designs, such as embossed or shaped-metal cladding. cladding enables structures to be made with much less weight than solid copper.

plastisol

plastisol is a suspension of pvc or other polymer particles in a liquid plasticizer; it flows as a liquid and can be poured into a heated mold. when heated to around 177 degrees celsius, the plastic particles dissolve and the mixture turns into a gel of high viscosity that usually cannot be poured anymore. on cooling below 60 degrees c, a flexible, permanently plasticized solid product results. aside from molding, plastisol is commonly used as a textile ink for screen-printing and as a coating,

flashing weatherproofing

most flashing materials today are metal, plastic, rubber, or impregnated paper. 9 metal flashing materials include lead, aluminium, copper, 1 stainless steel, zinc alloy, other architectural metals or a metal with a coating such as galvanized steel, lead-coated copper, anodized aluminum, terne -coated copper, galvalume aluminum-zinc alloy coated sheet steel , and metals similar to stone .

aluminized steel

aluminized steel can be made using a variety of processes, cladding, hot dipping, galvanic coating, metallizing, and calorizing, but the most effective process is hot dipping. the process of hot dipping starts by cleaning the steel, then placing the steel in a bath of al-11%si at a temperature of 988k and shaken, then pulled out and air dried.

architectural metals

tin is too soft to be used by itself for architectural purposes so it generally falls into two categories: the alloying of tin with other metals such as copper to form bronze, and the coating of tin on harder metals, such as tinplated iron or steel. architectural bronzes usually contain about 90% copper and 10% tin, although the content may .
