Surface Preparation Standards, Part 1 – Evaluating Surfaces Throughout Finishing Processes

Surface preparation can account for up to 40 percent of structural steel painting and repainting jobs and the life of anti‐corrosion coatings on a steel surface largely depend on how thoroughly the surface was prepared before painting.

At Rosler, we have extensive experience evaluating structural steel surfaces for coating before and after shot blasting. This knowledge of surface preparation standards and the widely used ISO and SSPC standards guide us in developing systems to expertly prepare and repair structural steel throughout its lifespan.

The Standards

Evaluating rust and mill scale pre- and post-shot blasting is a must. It is important to clearly specify the quality of the surface prior to preparation as well as the surface conditions after preparation. As a result, standards were developed to visually assess the initial surface conditions and the quality of the required surface preparation relative to the initial steel surface conditions.

The dominant and widely used standards for evaluating rust and mill scale are ISO 8501‐1:2007 (based on the Swedish Standard SIS 05 59 00) and the SSPC (Steel Structures Painting Council). While different in some minor details, these standards are practically identical.

A Year in Review – Top Blog Posts from 2019

At Rosler, we believe in helping our clients in unique markets find a better way to finish and process their products. According to Grand View Research, Inc., the global structural steel market is expected to reach USD 140.4 billion by 2025. It is projected to expand at a CAGR of 5.6% during the forecast period. Increasing construction spending in emerging economies is projected to drive the demand for structural steel. Maybe that’s why our top posts this year included a series on Structural Steel. Enjoy the following recap.

5. Optimal Media Mix, Part 1 – Identifying and Maintaining Proper Levels

The best mass finishing equipment is useless without the proper media. That’s why the experienced engineers at Rosler Metal Finishing pair their quality equipment with the right type and amount of media to achieve consistent results.

Media comes in all kinds of shapes and sizes

Understanding how your machine, the work pieces it is finishing, and the selected media will interact is key to delivering an optimal finish each cycle. Doing so requires understanding why media levels are important, determining and tracking levels, and evaluating media consumption to avoid issues.
