The Kankana-ey Word for Yero or Corrugated Iron

"Sisim" is the Kankana-ey word for corrugated iron. Yero in Filipino. I wonder where the word "sisim" originated (or how). This is a modern term, a newly-coined word because corrugated iron was introduced to the Philippines by the Spaniards. We didn't have a word for it pre-colonialism.
