EQUAL ANGLES
•Roll-formed, mild steel and are formed by bending a piece of steel so it forms an “L”-shape, with a 90°,
perpendicular angle
•The legs of an equal angle's “L” are equal in size
•Used for reinforcing, mostly.
EQUAL ANGLES

UNEQUAL ANGLES
•Made from roll – formed mild steel
•Have one side of the 'L' that is longer than the other
•Typically used in framing and reinforcing
•The large the angle, the more weight it can bear
•Usually used for brackets

What is the difference between hot rolled and cold rolled sheet?
•Hot rolled steel comes with a scaly surface, slightly rounded edges and
corners and the surface is non-oily.
•Cold rolled steel has an oily or greasy finish, very smooth surface, and
very sharp edges

HOT ROLLED DRY SHEETS
HOT ROLLED PICKLED & OILED SHEETS
VASTRAP/CHEQUER PLATE What is pickled and oiled sheets?
Steel pickling and oiling is a metal surface treatment finishing process
used to remove surface impurities such as rust and carbon scale from
hot rolled carbon steel.
The steel is submersed in a bath of pickle liquor, a solution of Hydrogen
Chloride acid, to remove the impurities from the surface of the steel.
Will pickled and oiled steel rust?
Hot rolled pickled and oiled steel,is steel that has been processed to
remove surface impurities. When traditional hot rolled steel is pickled
Vastrap Plate and oiled, it becomes more durable and rust-resistant
•Hot rolled steel floor plate
•It is patterned to render a non – slip surface Hot Rolled Pickled and Oiled steel is ideal for welding finishes and
reinforcements.

Y Standards
Y standards are the most widely used type of steel standard.
K Standards
K standards differ from Y standards in shape and weight.K Standards are
lighter and cheaper.
Security Standards
Security standards can be manufactured from either Y standards or K
standards. The overhang of 450mm can be made from flat bar, tube or from
the same section as the standard itself.
Steel Standards
Steel standards and droppers are coated with black bitumen.
Droppers
• Generally used in constructing barbed wire fencesand game fences.
• Have ridges in order to keep lines
of barbed wire separated.
• Not designed to go into the ground.
