METgrain’s® unique mix of spherical and irregular-shaped steel particles was developed specifically for steel surface preparation. METgrain® Steel Abrasive is especially effective when critical profile tolerance is needed.
METgrain® enhances blast cleaning efficiency by combining impact with scouring action. The result is a cleaner surface with a superior anchor pattern at a lower cost.
Steel structures such as bridges, water towers, ships and storage tanks require painting maintenance to extend the life of the structure. Due to improper maintenance, many of these valuable structures owned by federal, state and local governments have their protective coating of paint peeling, flaking and rusting away; contaminating our environment and reducing the useful economic life of our valuable infrastructure.
The EPA mandates the minimization of waste to reduce dust and waste, protect our rivers and streams and to preserve our valuable landfills. Use of recyclable Metgrain®and METgrit® minimizes the generation of hazardous waste.
Blast cleaning and repainting protective coatings is necessary to extend the economic life of these structures. Proper blast cleaning and painting typically provides at least twenty to thirty years of protection. Failure by facility owners to repaint these valuable structures can cost millions in lost economic life of the structure. Open abrasive blasting of structures containing lead-based paint with one use mineral slag or sand violates RCRA mandates to minimize the generation of hazardous waste and exposes workers and surrounding neighborhoods to tons of potentially hazardous waste and silica dust with proven health hazards.
Reusable metallic abrasive solves all these problems and does so at less total cost. While a most enlightened state authorities mandate the use of recyclable abrasives in their bid documents, too many state, local governmental agencies, and private facility owners fail to do so. This problem cannot be solved without the understanding the high economic and environmental cost of using non-recyclable abrasives.
