1️⃣ Umthwalo Omkhulu (Iipleyiti Zentsimbi)
Ifanelekile ukuthunyelwa okukhulu kweepleyiti zentsimbi. Iipleyiti zihlala zibekwe ngokuthe tyaba okanye zihlanganiswe kwaye zilayishwe ngqo kwiinqanawa. Izilayi zokhuni okanye ii-anti-slip pads zibekwe ezantsi, kunye nee-battens zokhuni okanye izahluli phakathi kwee-plate layers. Ii-bundles zibotshelelwe ngeentambo zentsimbi, kwaye umphezulu ukhuselwe kusetyenziswa izigqubuthelo ezingangeni mvula okanye ioyile yokuthintela umhlwa ukunciphisa umhlwa ngexesha lokuthuthwa.
