Industrial sandblasting is the process of removing rust, scale, and paint from metal components using sandblasters. Sandblasting companies offer a variety of media, including sand, baking soda, and crushed walnut shells. The process is effective and commonly used to prepare surfaces for restoration or renovation. Mobile sandblasting crews are used for larger structures like bridges and overpasses. The process is not suitable for woodwork or ornamental finishes.
Industrial sandblasting is the business of removing rust, scale and paint from metal components for customers. Also called paint stripping companies, industrial sandblasting services use sandblasters to completely remove items as small as antique toy cars and as large as full-size cars and trailers. The typical industrial sandblasting business will offer a wide selection of sandblasting media, from sand to baking soda and crushed walnut shells, with each type of medium having its own specialized use.
When preparing to restore, renovate, or refinish a steel or metal object, a number of steps can be taken to remove rust, old paint, and even old chrome. Hand sanding is the basic method used to prepare a surface for a new finish. This, however, can be very time consuming and difficult. Chemical stripping can be messy and dangerous for both the user and the environment. The industrial sandblasting process is a very effective method of removing any unwanted residue on the metal surface and, in some cases, can also remove some of the rusted steel from the component to be stripped.
Industrial blasting typically involves bringing the object to be blasted into the ejector position. The item is placed in a blast cabinet and the correct type of media is loaded into the blast apparatus. Typically, the operator starts at one end of the object to be blasted and works in small areas until only the raw metal finish is left. Once fully sandblasted, the surface should be covered with a primer or sealer to resist rust caused by air humidity. Some industrial sandblasting companies are also mobile and are often used to dismantle brick and cinder block buildings before painting or renovation.
Other structures that are often blasted without being brought to the blaster location are bridges and overpasses on major highways. A mobile industrial blasting crew will load the equipment onto a truck or trailer and visit the bridge or overpass site, install large tarps to protect passing traffic from damage, and blast the area to remove old paint and other substances to allow workers to finish the object. When sandblasting a structure in preparation for painting, windows and other areas that need to be protected from high-pressure sand are covered with rubber mats or pads. Woodwork, wooden doors and ornamental finishes are generally not sandblasted and therefore protected from any type of damage resulting from industrial sandblasting.
