There is no testing to be done on i bar. We only have about 4 pieces of sample i bar from supplier.
Secondly, there is no alternative solution to this fabrication of i bar.
My opinion is to proceed with ordering of i bar.
Since last discussion with kong, din had a dateline to find alternative solution by 23 Jun. No solution found.
Please check with kong. We should not delay as there is a lead time for production of i bar.
