About Fabric Buildings

Not all steel framed, fabric covered buildings are created equal and not all manufacturers of steel framed, fabric covered buildings follow all requirements of building codes.  The following section provides the main reasons why a Defender Buildings fabric covered building (manufactured by Norseman Structures) provides a superior product in the market.

The National Building Code (NBC) provides design loads in their supplement.  The information below outlines several issues that are often not addressed properly in steel framed, fabric covered building design among competitors. This information will ensure you that you are selling a product that meets your customer’s requirements, is safe, minimizes liability and is insurable.



Norseman Structures is certified to CAN/CSA-A660, a requirement of engineered structures under the National Building Code of Canada. The new CSA-A660 requirements, released in the fall of 2009, introduce more stringent mandatory standards for fabric engineering than were previously part of the previous CSA-A660 certification. The new standards include full-system requirements covering the fabric supplier, fabric design engineer and fabric production facilities.

The CSA-A660 Standard was developed to assist government officials in reviewing building permit submissions incorporating a steel building system, and to help purchasers in obtaining a quality building. Customers may experience difficulty in getting permits without CSA-A660 certification.

The CSA-A660 Standard requires that the manufacturer’s suppliers, production facilities, design, engineering, staff, and quality assurance systems are capable of consistently producing quality buildings. The National Building Code of Canada states that “building systems shall be manufactured by companies certified in accordance with the requirements of CSA-A660 Certification of Manufactures of Steel Building Systems.”

CWB (Canadian Welding Bureau)

The Canadian Welding Bureau (CWB) has certified Norseman Structures’ manufacturing facility to CSA Standard W47.1 “Certification of Companies for Fusion Welding of Steel” in Division 2. Division 2 requires that Norseman Structures retain the services of a qualified Welding Engineer. Certified Welding Supervisors are on staff to control Norseman’s welding operations. CWB qualifies Welding Supervisors based on related experience, and examinations on welding symbols, weld faults, quality control and inspection methods. The welding operation is subject to third-party audits by CWB to assure continued commitment and performance to required standards.

AWS (American Welding Association)

The American Welding Society certifies manufacturing facilities to AWS B5.17, as an AWS Certified Welding Fabricator (CWF). The requirements for this program are set forth in an American National Standard, AWS B5.17, and Specification for the Qualification of Welding Fabricators. This specification defines compliance requirements for welding-related functions; and assures through third party assessment that the Welding Fabricator has the personnel, organization, experience, procedures, knowledge, equipment, capability, and commitment to conduct proper weldments.


Standard & FR (fire retardant) covers carry up to 20 & 15 year pro rata warranties respectively. Warranty details can be found in each Norseman Structures Building Owner’s Package shipped with the cover or building.
