TCSII - TCS2 - Terne coated stainless steel

Sheet metal available in different gauges

TCSII - TCS 2 - Terne Coated Steel

TCSII or TCS2 - Terne coated stainless steel sheet metal is manufactured with type 304 stainless steel coated in both sides with terne alloy (50% tin, 50% zinc). Highly corrosion resistant, which makes it an ideal roofing material. It offers a soft-looking protective patina that develops after exposure to the elements.

Attention: This material is not in production at the time. Riverside has a few sheets and some coil in stock available for purchase only if parts are fabricated with it, not as is.
Alternative 1: Freedom gray - This material has the same finished look but it is made with copper sheets instead of stainless steel.
Alternative 2: UGINOX® PATINA K44 - Called the “new terne coated stainless steel” is produced in stainless alloy 444 base, which contains 18% chromium, molybdenum and titanium, with an electro-tinned coating on both sides which tones down the natural luster and allows the surface to weather over time to a soft matte gray finish.

Used for masonry flashing, gutters, metal roofing panels, downspouts, chimney caps, cupolas, louvers, finials, edge metal, flashing, step flashing, leader heads, gutter accessories, conductor boxes and skylights.

Available in 3' x 10' sheets. 26 and 28 gauge.

Item Code: TCSII
