Taratasy varahina
Fampidirana vokatra
Varahina Sheet mifototra amin'ny electrolytic varahina, zinc sy ny singa manta toy ny akora, amin'ny alalan'ny fanodinana amin'ny ingot, mafana Rolling, mangatsiaka Rolling, hafanana fitsaboana, ambonin'ny fanadiovana, fanapahana, famaranana, ary avy eo ny fonosana. Ny fizotran'ny fitaovana, ny plastika, ny toetra mekanika, ny fanoherana ny harafesina, ny fampisehoana ary ny vifotsy tsara. Izy io dia nampiasaina be tamin'ny herinaratra, fiara, fifandraisana, fitaovana, haingon-trano ary indostria hafa
