from the format, looks like from 3Kim? 

Well 3kim were the first I got the quotation from and being a 3kim customer before you should know how detailed their itemized quotations are.

I took the exact same specs on their quotation including exact measurements/material/thickness/finishing and gave it to other vendors and not only were their estimate quotations cheaper, after onsite assessment, even cheaper after negotiating with them. FYI their not run of the mill steel vendors but those as big as 3kim as well with own factories etc.

Tried to negotiate with 3kim for a better price but guess how much discount they give from quoted price? Rounded down RM40 for a >RM10k job    My as well don't give any discount man.
