What to Prepare Before Contacting a Steel Building Factory: The 5 Documents That Get You a Real Quote

The short answer: prepare five documents before you contact a steel building factory — a site layout or plan, a clear dimension list, loading and local code data, delivery information, and a budget range. Factories that receive these five items return a usable quote in days; buyers who start with a one-line email usually spend an extra week exchanging clarifying questions.

Document 1: site layout and local conditions

(‘Send a simple site plan showing the building footprint, the available area, orientation and any existing structures. Add the local wind, snow and seismic zone if you know it, or at least the city and region so the engineer can apply the correct design loads.’, ‘If the site has poor soil, a slope or a high water table, say so. Foundation design depends on it, and the factory cannot price anchor bolts or base plates correctly without that context.’)

Document 2: building dimensions and openings

(‘List the length, width, eave height and roof slope you need. Then list every opening: doors, windows, louvres, ventilation fans, and any crane or mezzanine requirements. A complete opening schedule is the single fastest way to avoid rework at the shop drawing stage.’, ‘If you are unsure about a dimension, give a range rather than leaving the field blank. A range lets the factory quote the heavier option and you decide later; a blank forces a guess that may come back as a revision.’)

Document 3: loading and code data

(‘State the design standard you want the building calculated to, for example an ASTM or EN based code, and the local live load, snow load and wind speed if they are specified by your local authority. This is what the structural engineer needs to size frames, purlins and bracing.’, ‘If you do not have this data, the factory will usually apply a default from its own experience, but the resulting building may not satisfy your local approval process. When in doubt, ask which design code the factory will use and confirm it with your local engineer.’)

Document 4: delivery and logistics information

(‘Tell the factory the destination port or address, the expected timeline and whether you need FOB, CIF or DDP pricing. Steel buildings ship as containerized members or as break-bulk on flat racks, and the two methods have very different freight costs and lead times.’, ‘If the site is inland, mention it. The factory can then advise on container loading and on whether the members need to be designed to fit within container dimensions, which can affect the frame layout.’)

Document 5: budget and decision timeline

(‘Give a realistic budget range and your decision deadline. This does not invite a higher price; it tells the factory which standard options to quote first and whether to prioritize your job in the production schedule.’, ‘Also state how many suppliers you are comparing. Factories price differently when they know a buyer is running a competitive tender, and a clear timeline helps them reserve workshop capacity for your order.’)

What to ask back in the same round

• The steel grade and design code the quote is based on
• What is included and excluded (drawings, bolts, cladding, erection)
• The number of drawing revision rounds included
• The production lead time and the payment schedule
• The freight estimate for your destination and which incoterm is quoted

FAQ

Q: Do I need professional drawings to get a steel building quote?

A: No. Factories quote from dimensions and an opening schedule, which you can prepare yourself. Professional drawings speed up the process and reduce assumptions, but they are not required for a preliminary quote.

Q: What happens if I do not know the local wind or snow load?

A: The factory will usually apply a default load based on the city or region you provide. Confirm which design code and loads were used, and check them with a local engineer before approving the structural calculation.

Q: How long does it take to get a steel building quote?

A: With a complete five-document pack, many factories return a preliminary quote within 2 to 5 working days. Incomplete inquiries commonly take longer because each missing item requires a follow-up email.

Q: Should I give my real budget to a factory?

A: A range is enough. The purpose is to make sure the factory quotes options within your reach instead of wasting a round on a design you will not fund. A clear decision timeline also helps the factory schedule production.
