Ostro builds steel buildings engineered for cannabis growing and processing, where climate control, segmentation, and clean power are everything. We engineer and fabricate every building in our own factory just outside Augusta and ship it factory-direct, so you get a purpose-built grow-and-process facility at manufacturer pricing, backed by our price-match guarantee. Our clear-span red iron frames give you a column-free shell to lay out grow rooms, processing, and storage exactly how your operation runs.

Clear-Span Space for Sealed Grow Rooms

With no interior columns, you can partition the building into individually insulated, climate-controlled, sealed grow rooms for different varietals and stages, plus separate processing, packaging, and office areas. Walls can move as your operation changes, and the modular structure makes future expansion straightforward. It’s a similar clear-span approach to our agriculture buildings, tuned for indoor cultivation.

Framing Built for Your Fit-Out

The framing supports the interior your process demands, from hygienic sealed grow rooms to finished office and retail space, and it’s designed to carry the ductwork, piping, and electrical conduit a grow facility runs, so installation is clean and integrated rather than bolted on afterward.

Engineered for Heavy HVAC and Ventilation

Climate control makes or breaks a grow, so roofs and ceilings are engineered to carry multi-ton roof-mounted HVAC and air-handling equipment, with walkway and rail systems for safe access. The same approach we use on manufacturing and industrial buildings keeps heavy equipment overhead and the floor clear.

A Facade That Fits the Site

Standard PBR paneling comes in a wide range of baked-on colors, and buildings can be dressed up with masonry, commercial glass, insulated metal panels, ACM, or fiber cement to meet your brand and local zoning. Insulated metal panels also deliver strong thermal performance, which matters for holding precise grow conditions. Our in-house standing-seam roof, rollformed from 24-gauge steel on the Ostro-3000 profile, adds durability and weather protection.

Insulation for Climate and Humidity Control

Insulation is tuned to your R-value and budget, from fiberglass and spray foam to high-R liner systems and insulated metal panels for segmenting crops. Good insulation holds consistent temperature and humidity, protecting yields from mold and mildew and keeping energy costs down.

Double Your Floorspace with a Mezzanine

Need more usable area without a bigger footprint? An Ostro Mezzanine System adds a second level for grow space, storage, or offices, engineered and built by the same team as your building for single-source accountability.

Why Ostro

We don’t just sell steel buildings; we make them — engineered in-house, fabricated in our own factory, and inspected under IAS AC472, single-sourced from quote to delivery. The same clear-span, climate-controlled approach applies to our agricultural buildings, manufacturing, and industrial facilities.
