About the IWDC


Who is the IWDC?

The IWDC is a Member-owned purchasing and marketing cooperative. Its Membership and approved manufacturers/suppliers work together to grow and strengthen the network of independent gas and hardgoods distributors North America (the United States, Canada & Mexico).
The goal of the IWDC is simple: to create an environment that allows the Membership either to compete on an equal playing field with the national chains, or majors, or to have a competitive edge in the marketplace.
The core function of our cooperative continues to be aggregating the individual purchase requirements of Member companies and negotiating Vendor agreements based on the total aggregate. IWDC Vendor companies benefit from our volume, our growth, and preferred access to our Members.
To further illustrate who we are, the IWDC has …
  • $2 Billion plus in retail sales (IWDC Members in North America)
  • 600 plus locations all across North America
  • 200-plus vendor agreements encompassing hard goods, gases, and expense/cost controls
  • Member-exclusive brands: Weldmark® & PurityPlus® Specialty gases and equipment
  • Over $50 million annually in retails sales of exclusive IWDC Brands: Weldmark® & PurityPlus®
  • A strategically centralized product distribution center
  • An industry-experienced staff

  • Member-exclusive seminars and training
  • Online Weldmark University
  • National account opportunities
  • Centralized billing to support National Accounts
  • Operation, technical, and application seminars and training

Member Owners of our cooperative share in profits by receiving annual patronage dividends. The value gained by our Members goes beyond profit rewards to include intangibles like networking, sharing of best practices, and being part of something larger than each of their successful and proud businesses alone.
