  • 32% more break-in resistant
    Break-in resistance was measured with an impact weight of 9.3 lb dropped on the door at the latch point from incremental heights until the latch yielded under impact. (Test inspired by ASTM D-1037-99)
  • 20% more deflection resistant
    Deflection was tested by incremental weights loaded on an I-beam across the width of the horizontally-installed door. (Test inspired by ASTM C-203-99)
  • 30% more delamination resistant
    The delamination test involved pull suction on both sides of the door at the same time, followed by a tensile test until delamination occured. (Test inspired by ASTM C-297-04)
  • 37% better resistant to twisting
    In the twist test, the door was supported at three points while the free corner was incrementally loaded with weights.
  • No. 1 for corrosion resistance
    Corrosion resistance to regular basic salt spray was measured on a 6″ x 6″ section of the door installed in a salt spray cabinet for 72 hours. (Test performed as per ASTM B-117-03)
  • G–10 Warranty
    Gensteel doors come with an unrivalled 10-year warranty against delamination and a two-year warranty against material and/or workmanship defects.
Galvannealed Steel
Galvannealed steel is coated with a Zinc-Iron Alloy by a process known in the metallurgical technology, as the Hot-Dip Process. This process consists of passing cold reduced sheet steel in coil form continuously through a pot of molten zinc. As the steel leaves the pot, the amount of coating allowed to remain on the sheet is controlled by coating rolls which are used to establish minimum coating weights in accordance to ASTM Designation A525/A525M. The zinc coating is what protects the steel against corrosion. This protection acts in two ways. The zinc acts as a shield between the base steel and the atmosphere and when the base steel is exposed, such as at sheared or blanked edges, the zinc acts as a galvanic protector, sacrificing itself in the presence of corrosive elements. The coating structure consists of a layer of zinc superimposed on a thin alloys layer consisting of both iron and zinc. The solidification of the zinc layer results from crystallization of the bath metal.
