    Behind each of our doors is an innovative idea, state-of-the-art technology, and a team that strives to unite the strength of steel with the power of design.


    Our products are made of hot dipped galvanized steel with a zinc-iron alloy coating (A designation). This alloy offers superior corrosion protection compared to cold-rolled steel. For interior openings, we offer A40 (ZF 120) galvannealed steel, and for exterior openings, A60 (ZF 180) galvannealed steel.

    DE LA FONTAINE also offers stainless steel type 304 and 316 products, satin finish no. 4, for damp areas or for areas where corrosive products are in use. Stainless steel is also ideal for high-end projects due to its esthetic appeal.

    Our galvannealed steel is well suited to be painted directly, but we also offer a primer product as well as prefinishing for our clients. Our paint products are designed to respect the environment while meeting our industry’s performance standards.


    ASTM A653/A653M
    Our hot dipped galvanized steel is compliant with ASTM A653/A653M (Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process).

    ASTM A240/A240M
    Our stainless steel is compliant with ASTM A240/A240M (Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications).

    To ensure quality, our steel gauge exceeds the standards of NAAMM/HMMA 803-92.


    The total recycled content of our galvannealed steel is approximately 89.7%.

    This includes:

    • A total post-consumer content of 50.6%.
    • A total post-industrial content of 33.3%.
    • The remaining 5.8% is comprised of home scrap.

    The total recycled content of our stainless steel is over 85%.

     However, the mill makes no distinction as to the origin of the scrap.
