May 01, 2018Steel Shot & Grit Steel abrasive is a cost-effective alternative to other abrasives due to its toughness and high recyclability. It can be used on a variety of surfaces to effectively remove contaminants, texture a surface for proper adherence of a final coating, or in ABRASIVE BLASTING IN PRACTICE - Coatings and FabricationSteel, when it is abrasive blasted, has a surface that is rough like sandpaper, with a series of tiny peaks and valleys called surface profile. Coatings anchor themselves to the valleys of the profile, and the peaks are like teeth. This is why surface profile created by blasting is sometimes called an "anchor pattern" or "mechanical tooth."

How Does Grit Blasting Work?Grit Blasting ApplicationsEquipment Required For Grit BlastingTypes of Abrasive MediaSurface Preparation GradesComparing Surface Preparation TechniquesWhy Work with Kue Group?Grit blasting is the operation of forcibly propelling a stream of abrasive materialunder high pressure against a surface to clean or modify its surface properties. Theabrasive material is contained either in a stream of compressed air (dry blasting) orwater (wet blasting). Here at KUE Group we use a wide variety of abrasivesdependent on the clients specification and surface finish required and / or thesubsequent activity. Commonly useSee more on kuegroupComparing Surface Prep Standards - SSPC/NACE and ISO 8501ISO adapted it into their established order as Sa 2 1/2, Very Thorough Blast Cleaning, but SSPC went outside the order, adding it chronologically as SP 10 Near White.

Specifically, hell be blasting the steel girders under a bridge. According to the specs, the steel needs to be prepared to white metal with a 2.5 mil anchor pattern for the coating to adhere to. This is new construction, so he only needs to knock off mill scale.
The two ASTM standards that govern the measurement of blast profile include D 4417, Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel and D 7127, Standard Test Method for Measurement of Surface Roughness of Abrasive Blast Cleaned Metal Surfaces Using a Portable Stylus Instrument.
