Marekani ilitangaza hatua mpya za kupiga marufuku kampuni za chuma na madini za Urusi…
Koili/shuka za chuma cha pua zilizopakwa rangi mapema ni rahisi kutunza na zinapendeza zaidi kuliko koli/shuka za chuma za kawaida.Inatumia chuma cha pua cha hali ya juu na mchakato wa kupaka rangi bora.Tuna uteuzi mpana wa koili za chuma cha pua zilizopakwa rangi kwa matumizi ya kibiashara, viwandani na mengine.
