Bead Blast Non-Directional Metal Finish

Bead Blast Non-Directional Metal Finish


Bead Blast is a non-directional finish that is uniformly textured and low gloss. Its lower reflectivity makes it suitable for roofing applications. Bead Blast can also be used for wall panels, coping, and trim. The consistency of the finish makes it excellent for panel-to-panel matching. Can be coated with anti-fingerprint coating for interior use.


For the best results over time, selection of the proper grade of Bead Blast is important. Type 304, for most environments, is sufficient to prevent corrosion. Type 316 should be used near the seacoast. Low carbon versions of these grades (304L / 316L) should be used when parts are to be welded. see table i in data sheet for highlights of chemical analyses and properties. for extreme locations, e.g. near chemical plants or where steel may come into contact with salt water spray, different alloys will be required, subject to application review.

Should a fire occur, Bead Blast provides additional protection as stainless steel has a melting point of 2750° F.


Bead Blast is supplied within five I units of flatness, which is well below standard commercial allowances.


Bead Blast can be welded or soldered. Preferably, use a grade of welding wire more noble than the work piece. Through use of shield gasses, formation of a heat tint scale may be avoided in lighter gauges. When scale does form, care must be taken to remove it through mechanical or chemical means. Because Bead Blast is non-directional, there is no need to orient panels in relation to the rolling direction. Still, to avoid the possible result of slight directional differences, we suggest panels be fabricated to maintain the alignment of the original sheet. After soldering, flux residue must be removed.


Bead Blast comes with a protective PVC covering that is high grade UV resistant and is designed to withstand the elements for several weeks. Yet it is recommended that this PVC covering be removed immediately after installation to prevent adhesive residue from adhering to the stainless steel finish. Bead Blast’s appearance is very uniform, but any metal surface, including a painted one, is sensitive to misalignment of panels on differing planes. Please take extra care to install within reasonable tolerances to ensure full benefit of Bead Blast’s unvarying appearance. After installation, remove any rust stains from tools/construction debris.


Bead Blast is designed to be essentially maintenance free. Bead Blast will last for decades without requiring attention. Yet it may be appropriate at times to clean the surface in order to maintain its original appearance. Specific stainless steel agents are widely available. For general cleaning, any detergent or ammonia solution is effective. For stains, a sodium carbonate paste with a warm water rinse can be applied. For severe stains, you may use tri-sodium phosphate and caustic soda solutions. More difficult contaminants, like adhesive residue, will come off with pure acetone. Always avoid products containing chloride. Regularly clean out areas where occasional debris may collect, such as gutters.
