Metals and sheets of different thicknesses are bundled without bundling and tied transversely with 5 – 8 steel lashes and longitudinally with 1 – 5 steel ties. An oxidation layer (scale), which gives constrained erosion assurance, is shaped on the outside of steel during hot-rolling or toughening. This layer is, be that as it may, profoundly touchy and may effectively drop off.
