A 100×300 steel building gives you 30,000 sq ft (2,787 m²) of clear-span, column-free floor built for scale. In 2026, a 100×300 runs roughly $3.54M–$5.46M CAD turnkey ($118–$182/sq ft), or from about $660,000 as an engineered kit. The 300-foot run suits large distribution and fulfilment centres, extended production and conveyor lines, and phased facilities, while the 100-foot clear width keeps drive lanes and staging open.

What a 100×300 Steel Building Costs in 2026
Titan prices a 100×300 in three tiers, so you buy only the scope you need. The ranges below apply Titan’s 2026 per-square-foot rates to 30,000 sq ft; the same rates drive the comparison figures on the Steel Building Sizes hub.
| Package | What’s Included | Total Range (CAD) | Per Sq Ft |
|---|---|---|---|
| Engineered Kit | Primary frames, purlins, girts, bracing, anchor bolts, fasteners, and NBCC/CSA A660 stamped drawings | $660,000 – $1,290,000 | $22 – $43 |
| Building Shell | Kit plus roof and wall cladding, trim, gutters, and framed openings to weather-tight stage | $1,290,000 – $2,160,000 | $43 – $72 |
| Turnkey | Kit + foundation + erection + insulation + interior finishes + MEP rough-in + permits | $3,540,000 – $5,460,000 | $118 – $182 |
What Drives the Cost of a 100×300
On a 30,000 sq ft building, the dock bank, clear height, insulation, and regional loads move the price the most, and at 300 feet expansion-joint detailing is engineered in. The table shows the direction each pushes cost.
| Cost Variable | Directional Impact on Price |
|---|---|
| Dock banks & levellers | The 300-foot wall supports a large dock count; docks and levellers are a leading cost driver on fulfilment and distribution builds. |
| Eave height | 18 ft to 32 ft adds wall steel across 800 linear ft of perimeter; high-bay and ASRS racking sit at the taller end. |
| Expansion joints | At 300 feet, roof and slab expansion-joint detailing is engineered into the design, which affects framing and slab layout. |
| Insulation system | Conditioned or cold-chain envelopes across a large area add materially over a basic shell. |
| Snow & wind loads | Regional ground-snow and wind loads add frame tonnage across the long roof line. |
| Interior finishes & services | Offices, sortation mezzanines, and MEP rough-in move a shell toward turnkey and set the high end of the range. |
What a 100×300 Steel Building Is
A 100×300 steel building is a pre-engineered metal building (PEMB) measuring 100 feet wide by 300 feet long — 30,000 square feet of column-free floor. The 300-foot run is built for scale and flow: long racking aisles line up end to end, an extended production or conveyor line has room to run without interruption, and a large bank of dock doors along the sidewall feeds high-throughput fulfilment, all while the 100-foot clear width keeps drive lanes and staging open. At this length, roof and slab expansion joints are engineered into the design. “Pre-engineered” means the frame is designed and fabricated to your site’s exact snow, wind, and seismic loads before shipping, then bolted together on site, with stamped, province-specific drawings included. See how the 100×300 sits among neighbouring sizes on the Steel Building Sizes hub.
Province-by-Province Pricing
The per-square-foot ranges above are Canada-wide; where you build shifts the finished cost through snow load, seismic design, labour rates, and freight distance. The modifiers below are directional — your quote reflects your municipality’s actual code requirements.
| Province / Region | Directional Modifier | Why |
|---|---|---|
| Ontario | Baseline | Deep supplier and trade base near the GTA keeps steel logistics and erection crews competitive. |
| Alberta | Near baseline to slightly lower | Strong industrial construction capacity and moderate seismic demand keep costs efficient outside the mountains. |
| Saskatchewan / Manitoba | Slightly higher | Heavy ground snow loads add frame tonnage, and longer freight hauls to remote sites raise delivery cost. |
| British Columbia | Higher | Coastal seismic design and elevated labour rates increase both engineering and erection. |
| Quebec | Slightly higher | High snow loads and provincial code and permitting steps add to the finished cost. |
| Atlantic Canada | Higher | Coastal wind exposure plus freight distance to the Maritimes lift cladding and shipping line items. |
What You Can Build in a 100×300
The 30,000 sq ft clear span, in a long footprint, makes the 100×300 a large-scale distribution and production building. Common uses include a large steel warehouse, a logistics or fulfilment hub with a long dock bank, an extended manufacturing or conveyor line, and temperature-controlled cold storage. As a fully engineered industrial building, it can be built now at full length or phased for future expansion.
Sample 100×300 Builds Titan Delivers
Large distribution or fulfilment centre
A 100×300 lines a long bank of dock doors along the 300-foot wall, with deep racking aisles behind — a high-throughput fulfilment hub sized for regional or e-commerce distribution.
Extended production or conveyor line
Three hundred feet of clear span gives a continuous manufacturing or conveyor line room to run, with a mezzanine control room overlooking the floor.
Phased or cold-storage facility
Built now at 300 feet or engineered for a future end-wall extension, a 100×300 can also carry an insulated, freezer-rated envelope for cold storage.

Frequently Asked Questions
How much does a 100×300 steel building cost in Canada?
A 100×300 (30,000 sq ft) steel building typically costs about $3.54M to $5.46M CAD turnkey in 2026, which works out to roughly $118 to $182 per square foot. As an engineered kit only it starts around $660,000. The size of the dock bank and the insulation package are the biggest levers within that range.
How big is a 100×300 steel building?
A 100×300 is 30,000 square feet — 100 feet wide by 300 feet long, or about 2,787 square metres. Because it is clear span, all 30,000 square feet is column-free, and the long footprint suits flow-through distribution and production.
Is a 100×300 steel building fully clear-span?
Yes. The 100-foot width is engineered as a clear span for the full 300-foot length, so racking aisles and material flow run uninterrupted and the entire 30,000 square feet stays usable.
How many dock doors fit on a 100×300?
The 300-foot sidewall typically supports ten to twelve dock doors at standard spacing, each with a leveller and seal. That large dock bank is what makes the 100×300 a strong fit for high-throughput fulfilment and distribution.
Is a 100×300 good for a fulfilment centre?
Yes. The long dock bank plus deep racking aisles behind it is exactly the layout regional and e-commerce fulfilment needs, and the clear span keeps sortation and conveyor lines free of columns.
What eave height suits a 100×300?
High-bay and ASRS racking commonly specify 28 to 32 feet, while lighter distribution and storage run 18 to 26 feet. Taller eaves add wall steel across the long perimeter, so match the height to your racking system.
Does a 100×300 need expansion joints?
Yes. At 300 feet, roof and slab expansion-joint detailing is engineered into the design to manage thermal movement across the long structure. Titan builds this into the framing and slab layout from the start.
What foundation does a 100×300 need?
A slab engineered for racking, forklift, and truck loads, with dock-pit detailing where docks are required and expansion joints across the long slab. Soil conditions and your racking and equipment loads set the final design.
Can a 100×300 be built in phases?
Yes. A 100×300 can be engineered so the end wall becomes a future expansion point, letting you extend the length in a later phase as the operation grows, without rebuilding the existing structure.
What is the lead time for a 100×300 steel building?
Lead time varies with engineering, provincial permitting, and the current Titan production schedule, and a 30,000 square foot frame takes longer to fabricate than a small building. Contact Titan for a current timeline for your province and site.
Is a 100×300 cheaper per square foot than a 100×200?
Usually a little, because fixed costs spread over 30,000 versus 20,000 square feet, though the total project cost is higher. Your exact rate depends on dock count, insulation, and region, so a quote is the reliable figure.
How does a 100×300 compare to a 100×200 or 150×300?
A 100×300 (30,000 sq ft) adds 100 feet of length over a 100×200 (20,000 sq ft) at the same width, while a 150×300 (45,000 sq ft) keeps the 300-foot length and adds 50 feet of width. Choose by whether you need run length or a wider floor plate.
