Steel Grit - Marine Paint and Painting Equipment
Steel grit is an angular ferrous abrasive used in shipyards for abrasive blasting and surface preparation of steel hulls, decks, tanks, and marine structures. It removes rust, mill scale, old coatings, and weld residues before application of marine paint systems.
ProShipWorks provides end-to-end support to source and supply Steel Grit for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common references include ISO 11124-2 for metallic blast-cleaning abrasives made from chilled-iron grit and SAE J444 for cast steel shot and grit size designations. Surface preparation performance is commonly specified with ISO 8501-1 and ISO 8503. |
|---|---|
| Class Approval | Steel grit itself is generally not class-approved as a standalone spare item. DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK may approve or inspect the overall coating and surface-preparation system when required by vessel rules or project specifications. |
Installation, Maintenance & Safety Information
| Installation Notes | Use in compatible blast cabinets, blast rooms, or abrasive recovery systems. Select grit size and hardness according to the steel condition, coating-removal requirement, blasting equipment, and specified surface profile. Remove dust and abrasive residue before painting. |
|---|---|
| Maintenance Tips | Recover and screen abrasive regularly to remove fines, paint chips, rust, and other contaminants. Monitor abrasive breakdown, dust generation, blast pressure, and surface profile. Replenish the working mix as required. |
| Safety Notes | Use a certified abrasive-blast helmet with supplied air, protective clothing, gloves, hearing protection, and suitable respiratory controls. Isolate the blasting area, control dust and ricochet, inspect hoses and couplings, and follow the abrasive manufacturer's safety data sheet. |
