This is a type of cable tray and cable ladder made of pre-galvanized, electro-galvanized or hot-dip galvanized sheet material that will meet the working conditions of the environment, ideal for indoor and outdoor use in commercial or industrial environments with high cable density. Trays with a strong structure to meet the needs of the sectors in use have a covered structure, interlocking splicing options, a wire tray structure that facilitates high cable density and stainless steel material demands are met in addition to sheet metal material. Cable trays and cable ladders are produced in 3 meters as standard, but also in 6 meters if desired in fully automatic lines where the Roll Forming method is used Cable ladders using the robotic welding system are structurally stronger.
