Pollen drift the distance it can travel and via what methods, and how to plant their fields to avoid unwanted cross-pollination. Corn pollen is particularly prone to pollen drift. Corn plants release their pollen for around a week, and an entire field may take up to two weeks to completely release its pollen; pollen release usually shows a spike two to three days after half the plants have released their pollen. Each individual plant can produce 4 to 5 million individual pollen grains. Its pollen is among the largest particles that can be found in the air, and is spherical in its
Coil coating Coil coating Coil coating is the continuous and highly automated industrial process for efficiently coating coils of metal. Because the metal is treated before it is cut and formed, the entire surface is cleaned and treated, providing tightly-bonded finishes. (Formed parts can have many holes, recessed areas, valleys, and hidden areas that make it difficult to clean and uniformly paint.) Coil coated metal (often called prepainted metal) is often considered more durable and more corrosion-resistant than most post painted metal. Annually, 4.5 million tons of coil coated steel and aluminum are produced and shipped in North America, and 5 million
