Thin plate cannot hold its shape when cyclinders are laid down. It is therefore necessary to support them.
We will always advise you of different solutions for transport to support plates with the diameter: thickness ratio is too high to support the plates. We have a variety of transport supports and cradles to help.

Quality Of Finish
Depending on the size, tees are either split using a shearing process or a flame cutting process.
'Sheared edge' smiliar to sheared plate. Additional grinding may be necessary depending on application. Some loss of width in addition to the normal beam manufacturers tolerance.
Flame / Plasma cut tees:
Usually 2/3 mm loss of width per cut. Tees are supplied as cut. When reversing the tees to produce tapered tees the loss of width is compunded and some remedial welding may be necessary to achieve your exact width.
Straightness of tees:
Tees are straightened to BS 4/N.S.S.S tolerances. Finer tolerances can be achieved at cost.
Plate Cutting tolerances are +/- 3mm
