Practical Notes

Industrial environments often require robust anti-corrosive treatments; ensure the specified primer (like red oxide or zinc chromate) and final paint systems meet site exposure requirements.

Refer directly to IS 1081 for proper installation, fixing, and glazing procedures of these steel windows on-site.

Wired glass is frequently preferred and specified in these windows for added safety and fire resistance in industrial applications.
