We already checked detail of material which you quote price base on Main structure use SUS 304.
You mean that all of platform you use material SUS304 ?
In case of you quote detail as above, We have some request need you down specification for reduce cost.
First one " Main structure" ( Main is meaning Colum and reinforce ) please revise specification to "Hot dip Galvanize".
( Can reduce cost better than SUS304)
But Operator must touch position (Step, Stage, Trap, Hand rail Etc. ) must use US304.
Please revise quotation and send to me again.
