TOOLS 00 · INDEX
Two tools: a weight calculator and a specification checklist you can send us.
The calculator runs in your browser and sends nothing. The checklist turns an enquiry into eleven inputs. What a finished quotation looks like is documented in the ordering-process guide, not in a third tool.

What these tools do not do
They do not size a structure. A weight calculator tells you what a tube weighs; it does not tell you whether that tube carries your snow load.
If you want the numbers checked before you send them, send the calculation and the load case together on the RFQ page.
