ANCHOR BOLTS
Also called Hold down bolts, can also be U-Bolts, Chemical bolt, L Bolt, sleeve or dyna bolt. Their Purpose is to anchor the building to the foundation.

APEX PLATE
Connects the rafters of a portal framed building together.

BARGE FLASHINGS
"L " Shaped covering material. It extends from over the edge of the roof sheets.

BATTERNS
Usually resembling an ''A" Shape, this is smaller pressed section used in vertical mode to fix internal panelling or Horizontal cladding. Alternatively it can be used for mid span bracing standard size 64mm

BAYS
This is the spacing between the columns on the long wall (gutter side).

BEARERS
These are large C-Section or Z�sections . They are used to support floor joists.

TRIM ANGLES
"L" Section usually 38mm x 38mm or 50mm x 50mm used to attach roof sheets to gable ends.

BRACING STRAP
These are used for structural cross bracing.

CASTLING
When fixed to the building, the end wall sheets look like battlements on a castle. This is because of the increase in overall height of each gable sheet in order to compensate for the angles rise on the wall. Builders may pre-cut the Gable sheet tops to the correct height and angle after fitting. The name of this process is Castling.

COLUMN
A vertical C-section which is Generally the same size as the rafters. The requirements of th engineer will determine the size of the column that is required.

COLUMN IN CONCRETE
Due to structural requirements, the engineer has deemed it necessary to embed the column into concrete to a specified depth.

CONNECTIONS
A connection refers to any point in the construction where two or more components are joined. The connection can be bolted or screwed as determined by engineer requirements.

CORNER FLASHINGS
The "L" shape cover material placed vertically in corner situations. Sizes may vary according to the specifications.

DOOR HEADERS
These are folded Z, C or TopHat sections used as a top connection on roller doors or P.A doors. A wall girt may sometimes perform this function.

DOOR JAMS
Folded C-section used vertically to house or mount a door on.

DOWN PIPES
A rectangle section usually 100mm x 75mm, formed as a conduit in order to dispose rain water that has collected in the gutters. Every length of down pipe has one end larger than the other end in order to allow for the joining of different lengths.

DROPPERS
These are short sections of C-section material that are used to connect the apex brace to the rafters. They are usually incorporated in buildings larger than 15m wide. These may be double or single section (back to back) and increase the strength of the building.

EAVE PURLINS
C-section , Attached to top of column either by way of folded angle bracket or by N section bracket.
