Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined.

Gas metal arc welding (GMAW), sometimes referred to by its subtypes, metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used.

Today?s modern metal storage buildings are no longer dilapidated backyard shacks. With construction innovation, your new storage structure can be as sophisticated as your home or business. Store tools, equipment, or documents. A metal building can keep cars, boats, or airplanes safe from the elements. Keep your belongings secure by storing on your own property and not in an expensive self-storage unit.

Prefabricated Metal Buildings use metal as its main building material. Although metals like iron and steel are commonly used in construction of concrete brick buildings, buildings made entirely out of metal have come up in the last few decades. Almost all the components, like beams, frames, columns, walls and roofs, are made from steel.
