Structural Steel Grit Blasting

Do you have a corroded steel structure that needs to be brought back to life? If so, our team of structural steel sandblasting experts can help you today! Using our state of the art abrasive blasting equipment we can assist you on your commercial, industrial or residential structural steel project today by removing all surface containments such as rust, paint, corrosion and any other imperfections on the substrate.

Grit blasting steel substrates creates a perfect surface profile promoting good adhesion for the protective coating to be applied, giving your project the longest possible life expectancy. After moving any rust, paint, grime or mill scale from your project via grit blasting technologies we work closely with our paint team to propose the suitable paint system necessary for each individual project. Our team of experienced protective coating applicators then come in to apply the paint system to relevant Australian Standards be it a single pack primer or a two pack 3 coat system, we can do it all!

When It comes to sandblasting steel we use one of the 4 grades below depending on the projects needs.

 

Sa 1    (Brush Blast) 
Light blast cleaning. When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and from poorly adhering mill scale, rust, paint coatings and foreign matter. The appearance corresponds to the prints designated Sa 1 in AS 1627.9.NOTE: Mill scale, rust or paint coating is considered to be poorly adhering if it can be removed by lifting with a blunt putty knife.

Sa 2    (Commercial Blast)
Thorough blast cleaning. When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and shall be free from most mill scale, rust, paint coatings and foreign matter. Any residual contamination shall be firmly adhering (see note to Sa 1). It corresponds to the appearance of the prints designated Sa 2 in AS 1627.9.

Sa 2½    (Near White Metal)
Very thorough blast cleaning. When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and shall be free from mill scale, rust, paint coatings and foreign matter. Any remaining contamination shall show only as slight stains in the form of spots or stripes and correspond to the prints designated Sa 2½ in AS 1627.9.

Sa 3    (White Metal)
Blast cleaning to visually clean steel. When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and shall be free from mill scale, rust, paint coating and foreign matter. It shall then have a uniform metallic colour and correspond to the prints designated Sa 3 in AS 1627.9.
