Transcript of METALS:

METALS:
Metals are solid materials that are typically hard, shiny, and features good
electrical
and
thermal conductivity.
FERROUS METALS
Metals are generally
malleable.
It's from the Greek word - "
métallon"
, "mine, quarry, metal"
These are metals in which
iron is the principle element.
The term "ferrous" is derived from the Latin word meaning
"containing iron".
STEEL
This is a malleable alloy of iron and carbon produced by melting and refining pig iron.
Rolled Structural Shapes
Rivets
Bars

Bolts
Rolled Structural Shapes
STEEL PRODUCTS
Sheet Piling
These are sections that are made to interlock and are available in several shapes.
Steel Pipe
This is a seamless or welded small diameter.
Reinforcing Steel
This is made from new steel or from discarded railway.
Welded Wire Fabric
Another type of reinforcing material.
It consists of parallel longitudinal wires.
Steel Straping
Made from high-tensile flat wire in a number of sizes.
Used for banding column forms to keep them from bulging.
Open Web Steel Joists
Lightweight warren type trusses made in several different styles

ALUMINUM
This is a lustrous, silver-white nonmagnetic lightweight metal.
Very malleable, has good thermal and electrical conductivity.
NON-FERROUS METALS
Aluminum Foil
- Used as a vapor barrier on walls and ceilings and as reflective insulation.
Copper
A lustrous reddish metal, highly ductile and malleable.
Has high tensile strength and is an excellent electrical and thermal conductor.
Lead
A soft, malleable, heavy metal. Very easy to cut and work.
Tin
A lustrous white, soft and malleable metal having low melting point.
This contains
no, or very little iron.
Steel provided people with tools of unsurpassed properties both in
war and in their preparation and processing.
Wrought Iron
This is produced when pig iron is melted to remove the carbon and other impurities.
Stainless Steels
These are made with chromium or a combination of nickel and chromium used in buildings.
Manganese Steel
Offers great resistance to abrasion.
Weathering Steel
It forms its own protection against atmospheric corrosion and thus requires no painting.
Sizes:
-Start with No. 2 or 1/4" (Divide a number of a bar by 8 to get the equivalent in inch diameter).
No. 2 = 2/8" or 1/4" diameter = 8mm
No. 3 = 3/8" or 3/8" diameter = 10mm
No. 4 = 4/8" or 1/2" diameter = 12mm
No. 5 = 5/8" or 5/8" diameter = 16mm
No. 6 = 6/8" or 3/4" diameter = 20mm
THANK YOU!
