Standard Sheet Copper is stocked in 1/8" hard temper, also known as "cold roll." Conklin primarily stocks 16 oz. copper (.0216" thick), with the main size being 3' x 10' sheets, sold in crates of 65 sheets. 20 oz. copper (.027" thick) is also available.

1/4" hard temper is standard for pan-forming coils, which require stiffer material than 1/8" hard copper. Stock sizes are 20" and 24" wide in 1,000-lb. coils. A 20"-wide, 16 oz. coil weighing 1,000 lbs. contains approximately 391 ft. of copper.

1/2" hard copper is also available and is typically sold as bus bar for electrical applications. The standard size is 4" wide by 144" long.

100-lb. rolls of 16 oz. soft copper are stocked in 20" widths and are also available in 16" and 24" widths. Soft copper is cold-roll copper that has undergone an annealing process to make it softer and more flexible. It is commonly used by roofers for valleys and flashing applications.
