What skills do you need to be a metal fabricator?
In addition to welding and blue print reading abilities, good dexterity is important. Other important qualities include math, mechanical skills and physical stamina as fabricators stand for long periods of time and use machinery like computers and other devices on factory floors.
What is the best material for duct work?
This type of ductwork is made of aluminum or galvanized steel. It's very durable, and its nonporous surface makes it the least likely to develop biological growth.
What is the most efficient ductwork?
Flexible Ducts can be one of the most efficient types of ducting systems, with relatively lower installation costs, because: They can be installed, commonly, without considerable planning and installation constraints.
What is HVAC fabrication?
HVAC fabrication is simply the manufacture and production of customized parts for the HVAC system of a building. The fact is that each building is uniquely designed and has unique needs with regards to its heating, cooling, and ventilation.
Can aluminum be used for ductwork?
Foam ductwork panels are coated with aluminum to prevent moisture and provide a corrosive free system. The coating is dependent upon the sheet metal ductwork fabrication operation but can be 80 micrometers to 200 micrometers for outdoor applications. Aluminum ducting is also available insulated or non-insulated from the main duct to the outlet system.
What is black iron ductwork?
Black Iron Grease duct is fabricated to safely transfer contaminated air, grease vapors, and heat. In a commercial kitchen, grease is heated to its vaporization point. Vapors then cool, condense and settle on colder surfaces. This produces a highly flammable hydrocarbon which can be very dangerous.
What is preinsulated duct?
Pre-insulated ductwork is installed in a single-fix and negates the need for the for the manual lagging process of insulating the ductwork after it has been installed. As the ductwork is comparatively lightweight and quicker to install, this can yield significant cost savings for the installer and / or contractor.
What is a PI duct?
Traditionally, PI Phenolic Pre Insulated Duct Panel is a panel of high strength, taking the Phenolic foam as the core material and with Aluminum on both the sides. It has a fine finish, has a long life material, light weight and easily transported, manipulated and constructed.
Does galvanized steel rust?
Galvanized steel takes a long time to rust, but it will eventually rust. This type is carbon steel that has been galvanized or coated with a thin layer of zinc. The zinc acts as a barrier preventing oxygen and water from reaching the steel, providing advanced corrosion protection.
