Why This System

STEP-G is a materials supplier. The window cleaner's relevant knowledge is that STEP-G extrusions in European windows follow European powder coat and anodising standards - not the Japanese standards that apply to TOSTEM or YKK AP residential products. European STEP-G extrusions in commercial construction are subject to the same care protocols as any European commercial aluminium window. The Japan connection is corporate ownership, not a different material science.

Pro Tips

  • STEP-G profiles are not distinguishable from other European commercial aluminium by appearance - you will not know you are looking at a STEP-G extrusion unless the fabricator tells you. Apply standard European commercial aluminium care to all commercial aluminium you encounter in European projects

What NOT To Do

  • Do not use alkaline cleaners on anodised STEP-G profiles
  • Do not use abrasive pads on any profile finish
  • Do not use acidic cleaners on anodised profiles

Does STEP-G publish an official cleaning guide?
STEP-G has not published an official cleaning guide. The protocol on this page is based on Justin Orloff's 25 years hands-on experience.

Yes, purified water via a water-fed pole is one of the safest methods for STEP-G glass. Ensure TDS is at or near zero before use and avoid directing high-pressure water at seals or gaskets.

Field Notes

“If a European commercial project uses STEP-G extrusions, the care protocol follows European commercial aluminium standards - Qualicoat powder coat or Qualanod anodising. The corporate parent being Japanese does not change the European finishing standard.”
