This fabricator-focused guide explains how to scope a shot blasting allowance for steel chimneys, stacks and complex fabricated assemblies. It deliberately avoids blanket rates: geometry, condition, required finish, access, containment, inspection and coating handover can all change the work package.
Collect drawings or photographs, geometry, flanges, openings, internal faces, current steel condition, proposed coating data, requested visual cleanliness grade, surface profile and inspection requirements. Add the workshop or site location, laydown, lifting and rotation arrangements, access, nearby operations, containment, waste and programme constraints. A useful quotation makes the resulting assumptions visible.
Plan when fabrication is complete and accessible, when blast cleaning can take place, the inspection hold point, and who accepts the prepared surface for coating. Programme risk often sits in handovers and access windows, not in blasting alone.
Cleanliness and surface profile should be defined around the coating system. The Steel Construction surface-preparation guidance describes the Sa grades referenced by BS EN ISO 8501-1 and the role of surface profile before coating.
Explore steel chimney shot blasting and send the available drawings or photographs, required finish and programme context. We will review the variables and state the scope assumptions rather than masking them with a generic rate.
