Note:  This  is  a  very  subjec.ve  pricing  based  on  the  standard  design  of  ready  made  cubic  tanks  .  To  get  a  more  accurate  pricing  based  on  a  specific  design,  it  will  require  some  .me,  not  un.l  the  end  of  holiday  on  the  11th.  The  making  charge  of  the  welders  will  vary  between  Dinajpur  and  Dhaka.    It  seemed,    this  par.cular  kind  of  metal  sheet  pricing  is  not  fixed  (open  for  bargain)  most  likely  because  this  was  not  a  standardized    industrial  product.
