Random Swirl is a decorative steel consisting of a patterned polished finish applied mechanically to the surface of stainless steel sheets. These decorative steel finishes can be created with various visual effects. They are designed for architectural applications such as wall panels, elevator cabs, coping, and trim.
SELECTING THE GRADE
For the best results over time, selection of the proper grade of Random Swirl 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, Random Swirl provides additional protection as stainless steel has a melting point of 2750° F.
FABRICATION & INSTALLATION
Random Swirl 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. Random Swirl is quite sensitive to alignment. Some projects may require the calculation of a border margin to ensure that panels with return legs that are installed next to each other are properly aligned. After soldering, flux residue must be removed. When installation is completed, remove any rust stains from tools/construction debris.
Random Swirl is designed to be essentially maintenance free. This decorative steel 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 debris may collect such as gutters.
