In architectural metal fabrication, the quality of surface finishing is not merely decorative—it is the frontline defense against microscopic crevice corrosion.
Surface Roughness & Particle Accumulation
A rough, poorly buffed metal surface contains microscopic pits and scratches where airborne soot, moisture, and road dust settle. High-grade rotary mirror polishing (Grade #8 buffing) creates a flat microscopic topography that sheds water droplets and dust effortlessly.
Passivation After Welding
During TIG welding, intense heat causes a heat-tint oxide layer. Proper post-weld chemical cleaning and mechanical buffing restore the protective chromium oxide film across the entire welded perimeter.
At Insaaf Steel in Haripur, our metal polishers employ multi-stage mechanical rotary buffing wheels to ensure every minaret section leaves our workshop with uniform brilliance.
