Steel framing is sized to match your site's exact snow, wind, and load requirements. We engineer it to your conditions, not a one-size-fits-all kit.

Steel trusses being erected during fabric building construction with boom lift

Steel trusses go up fast. Most buildings are fully enclosed in weeks, not months.

01 ACCESS & DOORS

Fabric building service door for personnel walk-through access

Service Door

Standard walk-through personnel access. Place them anywhere along the building length or on end walls.

Fabric building garage door overhead entry for vehicles

Garage Door

Standard overhead deployment for vehicles and equipment. Available on end walls or side walls.

Fabric building multiple garage bay doors for fleet access

Multiple Garage Bays

Wide multi-panel arrays for fleet operations. Get multiple vehicles in and out simultaneously without waiting.

Loading dock bay inside a fabric building

Loading Dock

Raised platform bay for transport trucks. Designed for high-volume logistics and distribution operations.

Open end fabric building with tractors driving through

Open End Wall

Full drive-through access. No door to open, no clearance limit. Ideal for loaders, combines, and large equipment.

All door hardware is engineered and galvanized as standard.

02 END WALLS

Fabric building steel panel end wall with metal sheeting

Steel End Wall

Full steel panel enclosure. Maximum security, best insulation potential, and a clean finished look.

Fabric building membrane end wall closure

Fabric End Wall

Tensioned membrane end closure. Cost-effective, lets natural light in, and keeps the weather out.

Fabric building open end wall with tractors inside

Open End

No end wall. Unrestricted drive-through access for equipment, loaders, and maximum airflow.

Fabric building combination end wall with steel lower and fabric upper

Combination

Steel lower panels with fabric upper. Balances ground-level security with natural light from above.

03 VENTILATION & INSULATION

Fabric building ridge vent along peak for passive exhaust

Ridge Vent

Continuous passive exhaust along the building peak. Standard on most configurations. Hot air rises and exits naturally.

Louvered ventilated fabric building end wall

Louvered End Wall

Adjustable louvers for natural cross-ventilation. Ideal for livestock barns and composting facilities.

Mechanical exhaust fans for controlled fabric building ventilation

Mechanical Exhaust

Powered fan systems for controlled air exchange. Required for dairy, composting, and industrial environments.

Cupola vent on fabric building roof for passive ventilation

Cupola Vents

Roof-mounted passive ventilation units. Supplemental airflow for large-span buildings and arenas.

Spray Foam

Closed-cell polyurethane applied directly to the membrane interior. Highest R-value per inch, best for heated buildings.

Liner System

Interior fabric liner with insulation blanket between liner and membrane. Clean finished interior appearance.

Reflective Barrier

Radiant heat barrier for moderate climates. Reduces solar heat gain in summer without full insulation.

04 MEMBRANE

Standard white PVC membrane with 16% natural light transmission

Standard White PVC

12 oz engineered membrane with 16% natural light transmission. 15-year warranty. The default for most buildings.

Heavy-duty PVC membrane and steel trusses inside a fabric building

Elite Heavy-Duty PVC

13.75 oz reinforced membrane for extreme wind, snow, and industrial environments. 20-year warranty.

Agriculture membrane interior showing 30% natural light transmission

Agriculture 30% Light

Exclusive to MegaDome, with nearly double the light transmission of standard membranes. Healthier livestock, lower lighting costs.

Fire-retardant membrane on a commercial fabric building

Fire-Retardant

CAN/ULC rated membrane for municipal and commercial buildings that require fire code compliance.

05 FOUNDATIONS

Concrete Blocks

Pre-cast base. Quick install, fully repositionable. The fastest way to get a building up.

Concrete Slab

Poured foundation. Permanent finished floor for warehouses, shops, and commercial applications.

Concrete Piers

Point-load anchors. Cost-effective for massive clear-spans where a full slab isn't needed.

Grade Beam

Elevated continuous beam. Combines pier benefits with a solid perimeter for a clean, stable result.

In-Ground Beam

Sub-grade pour. Flush-to-grade appearance with the structural benefits of a deep footing.

Continuous Floating

On-grade slab engineered for frost heave deflection. Works where ground movement is a concern.

Continuous Deep

Below frost-line footing for permanent cold-climate installations. The most robust foundation option.

Frequently Asked Questions

How long does a fabric building last?
The steel frame is designed to last 30+ years. Fabric membranes carry a 15-year warranty (standard) or 20-year warranty (Elite). When the membrane eventually needs replacing, the steel frame stays in place and a new cover goes on, typically in a few days.
What sizes are available?
These buildings range from 33 feet to 160 feet wide, with no interior columns at any width. Length is unlimited, and you can extend the building as far as your site allows. Peak heights range from roughly 15 feet to over 50 feet depending on the shape and width you choose.
Can I insulate a fabric building?
Yes. Three insulation options are available: closed-cell spray foam applied directly to the membrane interior (highest R-value per inch), a liner system with an insulation blanket between the liner and membrane, or a reflective radiant barrier for moderate climates. The right choice depends on your application, climate, and whether the building will be heated.
What makes these buildings different from other fabric structures?
All steel framing is galvanized, not painted or powder-coated, so it won't corrode even after years of exposure to salt, manure, or chemicals. The product line also includes an exclusive Agriculture membrane with 30% natural light transmission, nearly double the industry standard of 16%.
How quickly can a fabric building be installed?
Most buildings go up in a matter of weeks, not months. The exact timeline depends on the size of your building and the foundation type, but fabric buildings are dramatically faster to erect than conventional steel or wood structures. Foundation work is typically the longest phase. Once the pad is ready, steel and membrane installation moves quickly.
