TIW brings more than a century of experience in design, fabrication and construction of silos in many configurations and sizes for various environments to every project. We’ve continually improved our design and construction process to produce a safer, longer lasting and more durable product. Specific design considerations include:
Silos, BIns & Hoppers, Various Configurations
TIW designs, engineers, fabricates and constructs durable, high quality welded bulk storage silos, bins and hoppers for a number of industries such as wastewater treatment, cement, chemical, mining and aggregate industries. Our Silos are designed for storing large volumes and are cylindrical in shape, typically with a cone or mass-flow bottom.

Self-Supported Cone (Internally or Externally Stiffened)
Suitable for medium diameter silos. Internal and external stiffening allows for a large diameter roof design.
Highlights
- The bulk of the roof work can take place at grade
- These roofs are typically lightweight and can be hoisted to position by crane
- TIW can provide the design, fabrication and field construction of all ladders, stairways and platforms, providing a single source of procurement for your silo

Self-Supporting Cone (Structurally Supported)
A structurally supported cone roof suitable for a large diameter silo. It is often used to support additional roof loads, such as platforms, structures or heavy machinery.
Highlights
- Roof can be sealed
- TIW can provide the design, fabrication and field construction of all ladders, stairways and platforms, providing a single source of procurement for your silo

Self-Supporting Cone
Suitable for small diameter silos.
Highlights
- The bulk of the roof work can take place at grade
- These roofs are typically lightweight and can be hoisted to position by crane

Self-Supporting Umbrella / Dome
Typically constructed at grade level, then hoisted by crane to position.
The dome and umbrella are similar. The dome roof is formed with a spherical surface supported at its periphery, whereas the umbrella is a modified dome, where the horizontal section is a regular polygon with multiple sides with roof plates, supported only at the periphery.

A Track Record of Success
In the Mining, Minerals & Metals, Pulp, Paper and Forestry, and Alternative Renewable Fuels industries, your bulk storage equipment is critical to the efficiency of your operations, and must withstand harsh conditions and punishment in the field.
As Canada’s premier tank builder, TIW has established itself as a dependable partner for high quality construction of welded bulk Silos, Bins and Hoppers.
With more than 100 years in the industry, we understand how important it is to have the appropriate storage for your application. That’s why we work with you to review your specific requirements, performing a thorough assessment of the type and amount of bulk material you’ll be handling, then designing and building the optimal storage vessel that will last.

Appurtenances
Our design engineers can customize a wide range of appurtenances on the interior and exterior of your silos. At our in-house, 200,000 sq ft material processing plant,we fabricate everything from nozzles, couplings and piping to custom roof walkways, platforms and joining catwalks.
Here are some typical components we design, fabricate and install in our silos:
- Nozzles (with flanges, elbows, couplings and more)
- Ladders, radial and spiral stairways designs with handrail variations
- Roof walkways, platforms and joining catwalks
- Shell manways
- Rectangular and circular hatches
- Insulation rings
- Lightning arrestors
- Rescue davits
- Piping supports, cable support trays, grounding lugs
Prefabrication and planning
Methodology
Planning is as important as the cutting, forming and welding operations. We minimize costly field hours and crane time by pre-fabricating applicable sections of your silo, bin, or hopper in our shop facilities. With our decades of experience in the erection business, we’ve seen firsthand how maintaining pre-fabrication keeps costs in the field down.

Protective Coatings & Insulation
Silos stored products have potential for causing internal wear and corrosion.. We offer a variety of external coatings along with full or partial internal lining. We also offer additional corrosion options such as hot dip galvanizing, coating over galvanized components and fireproofing of structural structures.
Shop Pre-Coating
TIW can shop coat plates and appurtenances prior to shipping to site. This can help offset the high prices of field coating and help minimize open-air blasting which can be environmentally prohibited in some project locations.
Galvanizing
We provide galvanizing of various components – from nozzles, piping and support clips to stairways, handrails and platforms. In some cases, both galvanizing and coating are applied providing a superior protection.
Exterior Coatings
These coatings are applied to the exterior of the silo for corrosion protection and cosmetic appearance. Exterior surfaces are typically sand blasted to an SSPC-SP6 finish in preparation for coatings such as:
- High-performance epoxy primers and finish coatings
- Inorganic zinc coatings
- Holding primers
- Acrylic polyurethane coatings
- High-temperature coatings
Interior Linings
The interior surfaces may require specific protective linings. TIW removes all sharp edges prior to sandblasting. Some typical linings used might include:
- Epoxy primers
- Epoxy finish coatings
- Holding primers
- High temperature coatings
Insulation
When temperature control is required per design, TIW can supply and install a variety of mechanical insulation to meet the customer’s requirements. Insulation options can vary from the more common insulation batts with external cladding to prefabricated insulated panels. There are also different insulation and cladding material options.
Depending on design and temperature requirements, TIW can offer several insulation materials such as:
- Fiberglass
- Calcium silicate
- Mineral wool
- Cellular glass
- Perlite
- Polyisocyanurate
- Thin blanket
- Aerogel
