Product & engineering
A bolted structural system for grain leg towers, catwalks and stairs.
RapiSYSTEMS elements are fabricated from structural steel, then galvanized. With zero welding, the common pieces bolt together in tower, catwalk, stair and platform configurations.
Standard steel sections repeat across every tower and truss, which keeps unique pieces to a minimum.
Members bolt together on site. Welding is eliminated from the project.
Every piece is galvanized for durability and corrosion resistance in prairie weather.
Heights, lengths, widths and attachments are set to your bins, legs and conveyors.
All galvanized. All bolt together.
A RapiTower is the backbone of a grain leg. Four-post galvanized sections bolt together to the height your elevator needs, with platforms and attachment points set where your spouting, distributor and catwalks connect.
2-Post Towers carry RapiTruss catwalks and conveyors across your bin yard. They use the same galvanized structural sections as RapiTower, so supports can go almost anywhere along a run.
Wrap-Around Stairs turn a support tower into a safe way up. Flights and landings bolt to the tower frame, giving your crew walking access to the elevator head and catwalks.
RapiTruss catwalks give safe, continuous access for maintenance and operations, and carry conveyors from bin to bin. Truss sections bolt together to length and rest on RapiTower or 2-Post supports.
We lay out towers, catwalks and stairs around your bins and equipment.
The configuration is checked for your site, with an engineer when required.
Common structural sections are cut, drilled and galvanized.
Components ship from the prairies to anywhere in Canada.
Griffin Ag installs it, or any qualified crew can bolt it up. No welding crew needed.
Griffin Ag Services developed RapiSYSTEMS and installs it across Western Canada with its own heavy equipment, manlifts and equipped tool trailers.
RapiSYSTEMS bolts together, so any qualified crew can install it. For a single point of contact from quote to final bolt, ask for Griffin Ag installation.
Want to carry RapiSYSTEMS towers, catwalks and stairs? We are building a network of retailers and dealers across Canada.
Custom welded structure has its place. For bin access and conveyor support, a bolted system usually gets you there faster.
| Factor | RapiSYSTEMS bolted | Custom welded |
|---|---|---|
| Install time | Pre-made sections bolt together quickly on site | Custom pieces fabricated and fitted one project at a time |
| Labour | General crew with hand and power tools | Certified welders and fitters on site |
| Site welding | None | Hot work on site near grain and dust |
| Retrofitting existing bins | Add a catwalk or conveyor to the bins you have | Custom structure designed around each bin |
| Lead time | Common pieces, no long custom fabrication | Long fabrication and install times |
Figures come from the RapiSYSTEMS brochure. Items marked SPEC are pending confirmation from Griffin Ag.

No. RapiTower and RapiTruss are fully bolted systems built from common structural steel pieces, which eliminates welding from a bin access project.
Yes. RapiSYSTEMS was designed so farms can economically add a catwalk or conveyor system to an existing bin setup without specialized custom structure or long fabrication and install times.
According to the RapiSYSTEMS brochure, towers range from 6 ft wide by 20 ft tall up to 12 ft wide by 160 ft tall, in various widths, with custom heights available. Contact us to confirm sizes for your site.
RapiTruss catwalks and equipment supports can be configured to any required length in 5 ft increments, up to 400 ft, with supports placed at nearly any point along the length.
Yes. Wrap-around stairs are available as an option on RapiTower support towers.
Yes. All RapiSYSTEMS structure is galvanized for maximum durability and corrosion resistance.
We recommend Griffin Ag Services. They developed the system, know every piece, and can handle the install from delivery to the final bolt. Any qualified crew can also bolt it together, and we will ship the structure to them anywhere in Canada.
Yes. RapiSYSTEMS structure is sold direct and shipped across Canada. Griffin Ag Services also offers installation across Western Canada.
Yes. Griffin Ag Services, the team that developed RapiSYSTEMS, is the recommended installer and works across Western Canada with its own heavy equipment, manlifts and tool trailers. Because the system bolts together, any qualified crew can also install it. Visit griffinagservices.com or ask for installation in your quote.
Send us your bin layout and equipment list. We will configure the towers and catwalks to suit.
