Description
The Sia 2925 SialoX cloth sanding belt pairs an aluminum oxide grain with an X-weight cloth backing built to hold up through repeated passes on steel and non-ferrous metal. Each belt measures 3 x 21 inches at 120 grit and comes packed 50 to a box, so a fabrication shop can keep a full run on hand without reordering mid-job. The closed coat construction resists loading on softer metals while the reinforced cloth backing keeps the belt from tearing at the splice under continuous machine use.
Where the cloth sanding belt is used
This cloth sanding belt handles deburring, rust removal, weld preparation, and general surface finishing on unalloyed and low-alloy steel as well as non-ferrous metals like aluminum and brass. Fabrication shops run it for blending welds flush with surrounding material, removing mill scale before coating, and structuring a surface ahead of a final finish pass. The belt holds up in both dry and wet sanding setups, which matters on jobs where heat buildup or dust control pushes a shop toward wet grinding equipment.

The X-weight backing gives this belt more edge stability than a lighter J-weight cloth, so it resists folding over at a workpiece corner during aggressive stock removal. That stability, paired with the closed coat aluminum oxide grain, is what keeps a shop running the same belt through deburring and blending work without swapping grits mid-job. Order by the box to keep a machine running through a full production shift without interruption.
Pair this abrasive belt with the rest of a metal finishing lineup. For grain technology background, see the sia Abrasives site.
