Many customers ask whether the "steel-plate tote box" and the "sheet-iron bin" are two different products. In fact they mean the same thing: a bin with steel plate welded on all four sides, built solid for a long service life. This bin suits heavier, harder workpieces; it does not spill like a mesh warehouse cage and does not dent like a plastic turnover box. Nanjing Tongnuo Storage Equipment Manufacturing Co., Ltd. can build steel-plate bins in different specs to fit customer material dimensions.
