Currently, most hydrogen is made this way from natural gas. An electrical current can also be used to separate water into its components of oxygen and hydrogen. This process is known as electrolysis. Some algae and bacteria, using sunlight as their energy source, even give off hydrogen under certain conditions.
Originally, metal roofs were made of corrugated galvanized steel: a wrought ironâsteel sheet was coated with zinc and then roll-formed into corrugated sheets. Another approach is to blend zinc, aluminum, and silicon-coated steel.
Parts larger than these dimensions can sometimes be milled, but extra setups may be required. Typically, sheet metal milling is performed on aluminum and copper. Steel and stainless steel may also be milled, but cycles are longer due to the inherent cutting characteristics of these metals. We stock tooling for all of the above sheet metals.
