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

1 Comment

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.

Automation Part 7 – The Top 3 Mass Finishing and Shot Blasting Machines

Leave a comment

Rosler understands that automating aspects of your mass finishing and shot blasting processes has never been more critical.

As we have learned during recent world events, outside factors can have a significant impact on your ability to maintain a largely manual process. Though automated mass finishing and shot blasting machinery does require some human intervention, it can often be operated with a minimal headcount and limited human contact.

In previous blogs, we have explored how an automated-first posture can help you to gain significant efficiencies, lower costs, and increase your competitive advantage. We have also looked at the balance between automation and the environment and have discussed ways that you can mitigate environmental impacts of operating automated mass finishing and shot blasting machinery.

We now conclude our Automation Blog Series with best practice examples of automated mass finishing and shot blasting machines Rosler offers and the associated accessories and components available to help in building your next-generation automated processes.
