good morning, I have the need to preventive carpentry work: plates cut and welded and painted by sp. 15-40, welded supports; tubular structures (mounting operations) from 50x50x4 fine to 150x150x8 from 1x1mt to 6x6mt all certified. I wanted to know is always worth the speech of a basic price and/kg or should we also make a calculation at working hours? the assembly of the mounted structures should be calculated at hours?
I thank you for your kind answer.

the price €/kg is not always applicable.
depends on many factors such as profiles (sections, lengths and thicknesses), welding and surface protection (hot painting/zinc).
the best thing to do is to provide distinct and boards of the assemblies, subgroups and components.
in this way those who make the quote do not interpret and can give you a much more precise answer.
if you provide few details, who does the price you take a security margin for the unexpected and risk of having higher quotations than you should.
it can also happen that someone mistakes the estimate by defect and you will have problems during confirmation of order or execution of the works.

Thanks, of the prompt response, only a question in particular for the aeronautical ports there is a standard of quotation, because going to develop groups and subgroups takes a long time and silito the customer me from a trghet price.
