#6 Hairline is a two-step abrasive polished finish with superior matching characteristics. It’s designed for architectural applications. It boasts a more linear appearance than traditional #4 polish, which means it lends itself to repair and blending in the field. #6 Hairline is suitable for coping, trim, elevator cabs, and more. Can be coated with anti-fingerprint coating for interior use.
SELECTING THE GRADE
#6 Hairline’s performance depends on selecting the correct grade. Type 304 is sufficient for preventing corrosion in most environments. For most locations near the seacoast, Type 316 should be selected. For materials that will be welded, select low carbon versions of these grades (304L / 316L). See Table I in Data Sheet for highlights of chemical analyses and properties. For extreme locations, such as near chemical plants or where steel may come into contact with salt water spray, different alloys will be required, subject to application review.

TYPICAL SURFACE CHARACTERISTICS
Should a fire occur, #6 Hairline provides additional protection as stainless steel has a melting point of 2750° F.
#6 Hairline is supplied to standard commercial allowances of ASTM (American Society for the Testing of Materials).
#6 Hairline 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 this scale through mechanical or chemical means. #6 Hairline is directional, so it is essential to orient panels in relation to the rolling direction. After soldering, flux residue must be thoroughly removed.
#6 Hairline 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 finish. #6 Hairline’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 #6 Hairline’s unvarying appearance. After installation, any rust stains from tools or construction debris must be removed.
#6 Hairline is designed to be essentially maintenance free. It 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. Also, 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.
