Perforated Sunshades

Perforated Corten steel is a versatile and attractive material for projects that require durability and an artistic touch. It eliminates the need for a secondary process, such as powder coating . Weathering steel typically conforms to ASTM A242 , ASTM A588, and ASTM A606-4 standards. Where did Corten Come From? Corten is a brand name created by U.S. Steel in the 1930s. The name comes from "Cor," which stands for Corrosion resistance, and "Ten," which stands for tensile strength, or the strength of the steel itself. A fun fact—this steel was developed to avoid the added costs of painting! The rust layer that formed on the steel was stable enough to allow the material to sit out freely, eliminating the need for a secondary painting process. Weathering Steel Specifications ASTM A242: When the process was eventually developed in the 1930s, ASTM A242 became the standard applied to it. It is an HSLA (High Strength, Low Alloy) Steel type with a 50 min yield and 70 min tensile, up to 3/4" thick. ASTM A588: ASTM A588 is an update to ASTM A242. It remains the same in terms of physical properties, but the chemical recipe of the steel itself is different. Because of this difference, the physical properties (50 min yield/70 min tensile) go up to 4" thick. Thicker material exhibits reduced strength properties. ASTM A606-4: Another HSLA steel type. This one is also available as a cold-rolled product and in lighter gauges. ASTM A606 is commonly made into roofing panels., ASTM A847: This Corten specification applies to the pipe and tube market | Perforated Metal Sunshades and Sunscreens Perforated metal sunshades and sunscreens can be integral to a building — enhancing efficiency and aesthetics.
