CHEMICAL COMPOSITION
- The chemical composition of this category primarily includes elements used in the manufacturing of expanded metal products, which typically consist of carbon steel, stainless steel, or aluminum alloys. The precise composition varies based on the metal used; for carbon steel, it generally comprises iron with small amounts of carbon and possibly other elements such as manganese, silicon, and sulfur. Stainless steel variations contain higher chromium and nickel contents for corrosion resistance, with typical alloys including 304 and 316 grades. Aluminum alloys may include magnesium, silicon, copper, and zinc to enhance strength and durability. The specific choice of material and its chemical composition depends on the intended application's requirements for strength, weight, and environmental resistance.
MECHANICAL INFORMATION
- The category comprises a variety of expanded metal sizes with different mechanical attributes suitable for various applications. Each size is specified in terms of design size and opening size, with strands measured by width and thickness. Options such as 1/4" x #18 and 1/2" x #18 are lightweight, with nominal weights of 11.6 lbs. and 9.5 lbs. per 100 square feet respectively, indicating suitability for lighter-duty applications. Larger sizes like 1-1/2" x #9 provide greater nominal weight at 114 lbs. per 100 square feet, offering robustness for heavier applications. The minimum thickness ranges from 0.039 inches to 0.108 inches, while the overall thickness can be up to 0.120 inches in heavier variants. The percentage open area varies, influencing factors such as airflow and light passage, with designs like 1-1/2" x #13 providing up to an 80% open area. This versatility allows for the selection of designs based on specific mechanical requirements and aesthetic considerations.
AVAILABLE SIZES
- The available sizes for this category include 1/4" x #18 with a design size of 0.250 inches SWD and 1.050 inches LWD, 1/2" x #18 with 0.500 inches SWD and 1.250 inches LWD, 1/2" x #16 with 0.500 inches SWD and 1.250 inches LWD, 1/2" x #13 with 0.500 inches SWD and 1.250 inches LWD, 3/4" x #16 with 0.923 inches SWD and 2.100 inches LWD, 3/4" x #13 with 0.923 inches SWD and 2.100 inches LWD, 3/4" x #9 with 0.923 inches SWD and 2.100 inches LWD, 1-1/2" x #13 with 1.330 inches SWD and 3.200 inches LWD, and 1-1/2" x #9 with 1.330 inches SWD and 3.200 inches LWD.
