Shot Blasting at B.B. Price

When preparing architectural or structural steel for finishing, shot blasting is becoming the most popular process in the steel industry. This process removes debris from surfaces and produces a clean, polished finish ready for galvanization. 

Unclean oxidized material can be a cause for concern. Sharp edges and chipped sections can cause lacerations, causing ongoing issues with rust and uneven surfaces. Oxidized material also causes problems with the fabrication process therefore, it is always recommended that shot blasting is carried out before any type of welding or machining is attempted. 

What is this?   

Shot blasting is used to clean, strengthen, and polish metal by removing any grease, dust, and rust before repainting, remodeling, and galvanizing. It is of a similar process to the well-known sandblasting. Both have the same result but how they are actioned is slightly different. This method produces force from a mechanical device to propel treatment media onto the product ready for galvanizing. The treatment media consists of minerals, metal, glass, and organics such as walnut shells. It is slightly more aggressive than sandblasting therefore, it is better suited to non-delicate, larger surfaces or a commercial, large-scale purpose. 

Shot blasting vs sand blasting? 

Companies are leaning towards shot blasting rather than sandblasting due to the health risks associated with the sandblasting process and abrasive treatment. Sand used for the blasting process is widely made from Silica, whereas shot blasting is made from organic products. Inhaled Silica particles can cause severe respiratory illnesses by lodging in the respiratory system. Silica dust is also a known cause of lung cancer. Shot blasting is a non-carcinogenic process and contains no solvents meaning it poses no health risk to its user. 

The technique can be altered to suit the requirements of the desired result. The process can be adjusted depending on which result is preferred. Shot blasting can be finished in a smooth, rough, or fine surface area depending on the users' specific request.
