Metal Building 3D Quoting Tool for Steel Fabricators

In short: A metal building 3D quoting tool lets the buyer set span, length, eave height, roof pitch, frame type, cladding and openings, see the building assembled in 3D, and receive a quote calculated with the fabricator's own rules and prices.

A metal building 3D quoting tool is a web app where the customer, or the fabricator's sales rep, enters the span, length, eave height, roof pitch and frame type and sees the building assembled in 3D right away. The quote is calculated from that same configuration, using the shop's own sections, sheeting and prices, without going through the draftsman or waiting for the owner to run the numbers.

What people ask when they want a metal building

Anyone who has answered the phone at a steel fabrication shop knows the first question: "How much for a 10 by 20 building?" (meters, here in Argentina). That question doesn't have an answer yet. You still need the clear height (storing a seed drill is not the same as storing a truck and trailer), whether it's enclosed or open-sided, whether it needs a door, who pours the slab and where the site is.

The sales rep starts a back-and-forth over messages that can go on for days, and the customer often cools off before getting a number. A 3D quoting tool shows them a building that already exists and invites them to change it. The person who wanted "a 10 by 20" figures out on their own that with a 4 m (about 13 ft) eave the tractor won't fit, and raises it to 6 m before asking for a price.

What drives the price of a metal building

What moves the number on a steel building is well known in the trade, which is why it can be turned into rules:

1. Span and length. The span sets the frame section: covering 12 meters is not the same as covering 30. Length, together with frame spacing, sets how many frames you need.
2. Eave height and roof pitch. A taller eave means longer columns and more wall area to clad. The pitch changes the ridge height and the square meters of roof sheeting.
3. Frame type. Truss frame or solid-web frame, depending on each shop's practice and the span; a curved (arched) roof is a different product altogether.
4. Purlins and bracing. The number of purlins comes from the sheet length and the frame spacing; cross bracing is priced per bay.
5. Cladding. Open-sided (a canopy), half-height walls, fully enclosed in metal sheeting, or a block or brick base wall with sheeting above. Each option changes the square meters of sheeting, the masonry and the labor.
6. Sheeting and trims. Corrugated or trapezoidal profile, galvanized or pre-painted in color, plus flashing, fascia and ridge caps, which a serious quote prices as a separate line.
7. Openings. Sliding door (width and height), walk door, side windows, side lean-to canopy.
8. Slab and freight. Whether there's a slab, and the distance to the site, which matters a lot in rural areas.

A well-built quoting tool doesn't make any of this up: it takes the rules the owner already applies from memory or in a spreadsheet, as we explain in turning the owner's know-how into rules, and runs them the same way every time.

How the Estructuras 3D metal building configurator works

The metal building and canopy 3D configurator is public and runs in the browser, including on your phone. It doesn't show prices (that's part of the development for each fabricator), but it does handle all the structural and visual side:

• Dimensions: span from 6 to 40 m (about 20–131 ft), length from 6 to 90 m (about 20–295 ft), eave height from 3 to 12 m (about 10–39 ft), roof pitch from 5 to 35 % and frame spacing from 3 to 9 m (about 10–30 ft).
• Structure: truss frame or solid-web frame, adjustable section thickness, cross bracing and structure color.
• Roof: gable, single-slope or curved, with eave overhang and sheeting color. Sheeting trims are toggled separately, with their own color.
• Cladding: open, half-height, enclosed, block + sheeting or brick + sheeting, with base wall height and pilasters; front and rear end walls open or closed.
• Openings: sliding door with width and height, walk door, side windows and a side lean-to canopy with its width and slope.
• Floor: none, concrete, wood or rubber.

The spec sheet shows span, length, eave height, ridge height, number of frames and floor area.

Nothing is modeled by hand. Facundo Campo, who built the engine, designed it so every part comes from a rule: change the spacing and the number of frames and bracing bays changes; raise the eave and the cladding grows. That's what we explain in parametric rendering: there isn't one model per variant, there's a generator.

What changes in a fabricator's sales process

The most direct effect is that the number shows up during the meeting: the sales rep builds the building with the customer on the tablet, tries a block base wall and shows the difference. We cover that in the quote in the meeting, not in three days. There are other, less visible effects:

• Fewer quoting mistakes. Forgetting the flashing, miscounting frames on a length that isn't a multiple of the spacing, pricing roof sheeting without the eave overhang. With rules, those don't repeat.
• Prices that track steel. If section and sheeting prices live in a table the factory manages, when steel goes up you update one value and you're done. More in quoting when prices change every month.
• Inquiries that arrive already configured. From the fabricator's website, the WhatsApp inquiry already includes span, length, eave height, cladding and door.
• Production gets what was sold. The same configuration the customer saw can go out as a parts list for the shop floor.

A concrete example: the 18 × 30 building

A farmer asks for a building to store machinery. In the meeting, the sales rep starts from an 18 m span by 30 m length (about 59 × 98 ft), 6 m eave, 15 % pitch, truss frames every 6 m. That gives 6 frames. The farmer wants the front open to drive the combine in and the rear end wall closed; on the sides he wants a 1.40 m (about 4.6 ft) block base wall because of the livestock, with sheeting above. He also asks for a 5 m side lean-to to park the pickup.

Every change shows up instantly. The farmer turns off the cladding layer to see the structure and sends the link to his business partner, who opens it with that exact configuration. With live pricing (the part that's developed for each manufacturer), the side lean-to, the base wall and the door each add their own line.

What gets developed for each fabricator

For a specific fabricator, we load its rules: which spans it builds and with which frame, which sections it uses in each range, which sheeting it sells and how it prices freight. Depending on the project, that can include live pricing with a price table the factory manages, a PDF quote with the rendering, a sales rep panel and offline mode for agricultural shows. All of that is described in custom 3D quoting software, and what to have ready before you start is in what a manufacturer needs to have ready.

If you run a steel fabrication shop and want to see how your line of metal buildings would look in a quoting tool like this, open the configurator, build a building you sell often and send it to me on WhatsApp at +54 9 11 6193-3176 or by email at facundocampo100@gmail.com. That's enough to start talking about your rules and your prices.

Frequently asked questions

Does a metal building 3D quoting tool replace the structural engineer?

No. It works within the rules the fabricator has already set with its engineer: which section goes with each span, what spacing each frame allows. A building outside those ranges still goes through engineering.

Does the metal building configurator show prices?

The public configurator doesn't show prices. Pricing is added in the development for each fabricator, with its costs loaded in a table the factory manages itself, as in the EQUIBOX case.

Can the same tool quote open-sided canopies and enclosed buildings?

Yes. An open-sided shed is a metal building with open cladding: the structure and roof come from the same rules, and what changes is what gets closed in and with what. That's why the same quoting tool works for canopies, enclosed buildings and buildings with a masonry base wall.
