METALS PPT 6 CECMAT

METALS

and their alloys are integral part of construction industry. They are employed for various purposes such as structural members, roofing materials, doors, windows, tanks, pipes, etc.

Ferrous metal

are metals or metal alloys that mainly contain iron

Non-ferrous metals

These are metals that contain no iron but also include some alloys that contain appreciably very small amounts or iron.

CONSTRUCTION METALS

Aluminum

commonly used in the industry because it is resistant to corrosion, highly conductive and ductile.

CONSTRUCTION METALS

Copper tubing

which comes in two main types, is often used to construct pipes in buildings.

CONSTRUCTION METALS

Stainless steel

is among one of the oldest known building materials. It was used centuries ago to construct structures that still stand today, thanks to the corrosion and stain resistant properties of the metal.

CONSTRUCTION METALS

Cast iron

formed by remelting Pig Iron, and is useful for a variety of engineering purposes

CONSTRUCTION METALS

Wrought iron

purest form of commercial iron, containing only 0.10% to 0.15% of carbon and less than 0.25% of impurities like sulfur, phosphorous, silicon and manganese.

CONSTRUCTION METALS

Steel

is an alloy of iron, consisting of carbon (usually 0.1 to 1.7%), as a hardening agent.

STEEL SECTIONS

Angle sections

may have equal and unequal legs. Widely used in construction of steel roof trusses

STEEL SECTIONS

T sections

They are used as structural members in the steel roof trusses and also in the buildup sections

STEEL SECTIONS

Channel sections

They consist of one web and two flanges. Used as structural members in steel framed structures.

STEEL SECTIONS

I sections

Popularly known as beams and rolled steel joists, these are used for floor beams, columns, lintels, etc

STEEL SECTIONS

Expanded metal

Used for reinforcing concrete in foundations, roads, bridges, etc. It is also used for partitions

STEEL SECTIONS

Flat bars

Used in grill work for gates, windows, etc.

STEEL SECTIONS

Plates

Used to connect steel beams, roof trusses, tension members, built-up sections, etc

STEEL SECTIONS

Ribbed bars

Used as reinforcement in concrete structures.

STEEL SECTIONS

Square bars

Used in the grill work for gates, windows, etc. Commonly used cross section vary for 5mm to 25mm

STEEL SECTIONS

Round bars

widely used in grill works
