  • Customizability – With multiple colour options and the ability to mix and match the colours on a single cover, we let you decide what your building will look like. Whether you need to match your companies branded colours on a commercial site or make a zebra striped building because that’s what your kids asked for, you won’t be disappointed. Attaching massive banners and company labels are a breeze with our never settle attitude and creative design team.


With over 3 decades in business, Winkler Canvas has the experience and know how to design a building for any situation. Our engineered frame designs, superior steel, and no compromising attitude are what set us apart from the competition. Our buildings are designed to stand up to any weather and can be engineered under any building code worldwide. Winkler Canvas was among the first companies in the fabric structure industry to gain both A660 and ISO 9001 certification and refuse to cut corners. No wind or snow load is too much for our superior cross purlins, unique truss design, and Allied Gatorshield steel.

The Gatorshield Advantage:

  • Allied’s signature process produces superior corrosion resistance by utilizing a triple layer of protection. First 99.99% pure zinc is applied followed by a conversion coating. Finishing the process is a clear organic topcoat that seals in the protection and produces a smooth shiny appearance. Gatorshield provides 50% more zinc than any of the inline galvanized competitors.
  • We guarantee a minimum 50 ksi yield and 55 ksi tensile on our products with the ability to achieve higher properties with different steel chemistry. Compared with many alternatives that demonstrate a 30 ksi yield, Gatorshield demonstrates the unique ability to offer the same strength in a lighter weight tube – up to 33% stronger!
  • Gatorshield tubing is capable of being fabricated using several different methods including hole punching, cutting, flattening, bending and more without the degradation of the coatings. All of these operations can be performed without cracking, flaking or otherwise damaging the integrity of the coating. Because of this, we are able to make extremely custom alterations to our frame designs without compromising the steel.
  • Due to its 99% pure zinc coating; Gatorshield can be easily welded. Contrary to popular belief, all galvanized products do not perform the same with regards to welding suitability.

Winkler Structures and our employees are certified to the highest level. Whether your building is being used in a certification heavy industry like the Oil and Gas fields, or just a small hay shed on a local farm, we use the same level of quality and procedures for all of our manufacturing.

Canadian Welding Bureau (CWB)

The CWB Group is an industry supported private sector organization providing welding certification, management systems registration, and training services to over 7600 companies in 34 countries. Supported through the Canadian Welding Bureau, CWB Institute, QUASAR, and the Canadian Welding Association membership, the CWB Group provides a comprehensive and integrated service to the welding and joining industry.

The Canadian Welding Bureau was formed by the Canadian Standards Association (CSA) over 60 years ago. The purpose of the Welding Bureau is to administer Canada’s national welding standards, which are embedded in the national building code and other industry specific documents. Funded by industry, and acting on behalf of the Canadian public, the Welding Bureau plays an important role by certifying welding companies that create products for use within Canada as well as the welders and welding consumables used in their creation. Within the Structural and erecting industry it is mandatory that all companies be certified by the Welding Bureau. However, many non-welding companies choose to be voluntarily certified, as the Welding Bureau is the only organization that issues nationally recognized credentials.

International Organization Standardization (ISO)

ISO (International Organization for Standardization) is an independent, non-governmental membership organization and the world’s largest developer of voluntary International Standards. They are made up of 163 member countries that are the national standards bodies around the world, with a Central Secretariat that is based in Geneva, Switzerland.

International Standards make things work. They give world-class specifications for products, services, and systems to ensure quality, safety and efficiency. They are instrumental in facilitating international trade. ISO has published more than 19 500 International Standards covering almost every industry, from technology, to food safety, to agriculture and healthcare. ISO International Standards impact everyone, everywhere.

Canadian Standards Association – A660 (CSA-A660)

The CSA-A660 Standard was developed to assist code enforcement officials in reviewing building permit submissions incorporating steel building systems, and to help purchasers receive a quality certified building. The CSA-A660 Standard requires that the manufacturers’ production facilities, staff and quality assurance systems be certified by an independent certification agency. As part of the CSA-A660 compliance, the manufacturer will provide a “Certificate of Design and Manufacturing Conformance” signed and sealed by a licensed Professional Engineer for each building project. A sample copy of a Certificate is enclosed.

With the publication of the 2005 National Building Code of Canada (NBCC) a provision applicable to Steel Building Systems is added for the first time.

Specifically, the Article is as follows:

  • Steel Building Systems 1) Steel building systems shall be manufactured by companies certified to the requirements of CSA-A660, “Certification of Manufacturers of Steel Building Systems.”
