a = 20 mm indicates the width, t = 4 mm the thickness, and L = 2000 mm the section length. Dimension lines refer to the material’s outer edges. The diagram explains the labels. The proportions of this specific offer are defined by the dimensions in the table.
Material and surface
Unfinished aluminium without an additional decorative finish. The surface is not brushed, polished, anodised or painted. The main photo illustrates the general appearance of this material type.
If a specific aluminium grade or temper is required, confirm the material currently available before purchase.
Applications and selection for machining
The flat bar can serve as stock material for strips, spacers, washers or components machined by drilling and milling. Match the cross-section and material to the requirements of the finished component. When dividing the section, allow for the saw kerf and extra material for facing the ends and further machining.
Purchase and dimension selection
Buying one piece means one 2000 mm section. Buying three pieces means three separate sections of 2000 mm each. Beside the price, select the width, the thickness available for it and then the length. Each offer has its own price and availability.
Preparation and cutting
For a different dimension, contact the shop and confirm cutting feasibility, cost and tolerance. State the flat bar cross-section, individual section length and number of pieces.
