Steel warehouse buildings

Clear-span frames, docks, and cladding for Ontario sites.

Get a quote

We design, supply, and erect pre-engineered steel warehouses in Ontario. Typical jobs are storage, distribution, cross-dock, and light industrial buildings with dock-high or grade-level doors.

The frame is sized for the racking, forklifts, and truck access you need. Snow and wind come from the Ontario Building Code for that address. Drawings are stamped by a professional engineer licensed in Ontario.

Clear-span interiors

Rigid frames keep the storage floor free of interior columns, so racking and forklift aisles are not interrupted. Bay spacing follows that layout. Eave height is set for the mast, the rack, and the overhead doors.

If the building has to go wider than a single span, we use a multi-span frame. That is a layout choice, not a default catalog bay.

Loading docks and doors

Dock-high openings for highway trailers, or grade-level overhead doors for forklifts and straight trucks. Door count, dock height, and yard geometry go on the drawings with the frame reactions so the forming crew can pour to the bolt layout.

Personnel doors, windows, and an office or lean-to can sit on the same package.

Warehouse uses

Same building system. Different door walls, eaves, and insulation depending on the work inside.

Trucks at warehouse loading docks

Distribution and logistics

Dock-high walls, staging depth, and a clear floor for racking and forklifts. Cross-dock layouts if you need doors on two sides.

Storage and light industrial

Bulk storage, parts, and equipment. Grade-level doors where trucks and forklifts share the same floor.

Manufacturing and shops

Heavier frames where you need crane rails, pit openings, or high eaves for process equipment.

Warehouse with an attached office front

Heated and cold storage

Liner, insulation, and vapor barrier on the drawings when the volume is conditioned or refrigerated.

Offices and future bays

A lean-to office or a two-storey front keeps staff out of the warehouse volume without a second building. Same foundation grid, same cladding, one permit set.

Endwalls can be detailed so you can add bays later. Tell us if expansion is likely so the first frame is not a dead end.

Common options

Insulation and liners

Faced blanket, rigid board, or insulated panels. The vapor barrier has to match the use so you do not get condensation on the steel.

Daylight and ventilation

Skylights, translucent wall panels, and ridge or wall fans. Useful on long warehouses where electric light would run all day.

Mezzanines and offices

A lean-to, a two-storey front, or a mezzanine over a portion of the floor. Framed with the building so it is not a later fight with the columns.

Cranes and heavy use

If you need a bridge crane or heavy floor loads, say so at quote. The frames, bases, and bracing change.

What is in the steel package

Exact inclusions are on the quote. This is the usual warehouse package.

  • Primary frames, girts, purlins, and bracing
  • Roof and wall panels, trim, and fasteners
  • Openings framed for docks, overhead doors, and personnel doors
  • Drawings stamped by a P.Eng. licensed in Ontario
  • CSA A660 paperwork for the building system
  • Anchor-bolt plan and frame reactions for the concrete trade

Usually by others

We can write some of this into the job. If it is not on the quote, assume it is separate.

  • Slab, piers, and anchor-bolt installation
  • Overhead doors, dock levelers, seals, and shelters
  • Insulation labour if it is not in the written scope
  • Electrical, HVAC, fire, and sprinklers
  • Permits, zoning, and site plan approval

How a warehouse job runs

  1. Size and use

    Width, length, eave, dock count, door sizes, and whether it is heated. Site address for snow and wind.

  2. Drawings

    Stamped structural drawings, CSA A660 paperwork, and an anchor-bolt plan for the concrete trade.

  3. Fabrication and delivery

    Frames, secondary, panels, and trim sequenced for the job. Freight to the site.

  4. Erection and close-in

    Crane, columns, rafters, bracing, roof, and walls. Weather-tight when we leave, unless you are self-erecting.

Warehouse questions

How much does a steel warehouse cost?

Price depends on size, eave height, dock and door count, insulation, and whether we erect. Kit-only numbers leave out foundation, permits, and site work. A quote for your lot is the figure that counts.

What clear height do I need?

Set eave height from the rack, the forklift mast, and the doors, not from a round number. Distribution floors often sit in the mid-20s to low-30s in feet. Tell us the equipment and we will set the eave.

Can the building take docks and forklift traffic?

Yes. Dock-high and grade-level openings are framed into the walls. The slab and dock pits are concrete work. We put door sizes, dock height, and bolt layout on the drawings so those trades are not guessing.

Do I need a building permit in Ontario?

Most permanent warehouses do. Prefab or pre-engineered does not skip zoning or the Ontario Building Code. We supply stamped drawings and the CSA A660 paperwork reviewers usually ask for.

Can a warehouse be insulated and heated?

Yes. Lined and insulated warehouses are routine. Tell us the temperature you need so condensation, vapor barrier, and panel details are in the drawings from the start.

Can I add bays later?

Yes, if the first endwall is detailed for it. Say so at quote so the expansion end is not a full moment frame you have to cut apart later.
