A line card is the single sheet a metals stockholder hands over to say, in the fewest possible words, what shapes exist. This is the reference version of the one this site carried: the same grouping, the same vocabulary, but written as an index into the material pages rather than as an inventory.
Independent reference. This is an independent, non-commercial reference on metal forms, grades and mill processes. It sells nothing, quotes nothing and takes no orders, and it is not affiliated with any metal supplier, distributor or mill. See about this reference.
Angles
Bar-size angle and structural angle, in equal and unequal leg configurations, in carbon steel, stainless and aluminium. Aluminium additionally in an architectural profile with square corners and a uniform wall. See the form catalogue.
Bars
- Reinforcing bar — deformed bar for concrete
- Flats — hot rolled and cold finished
- Rounds — hot rolled and cold finished, plus turned-ground-and-polished shafting
- Squares — hot rolled and cold finished
- Hexagon — principally in brass and free-machining steel
- All-thread rod — carbon steel and stainless, cut to length
Beams and channels
I-beams and wide flange beams; channels in bar size, structural, and ship-and-car series. The section geometry that makes these efficient is covered under structural steel.
Sheets
Hot rolled strip, hot rolled, hot rolled pickled and oiled, cold rolled, galvanised, stainless, aluminium. Gauge series, finishes and the sheet/plate boundary are set out on the sheet and plate page.
Plates
Structural plate, manganese plate, abrasion-resisting overlay plate, quenched-and-tempered high-strength plate, hot rolled A36 mild steel plate, and raised-pattern floor plate.
Tubing and pipe
Rectangular, square and round structural tube; drawn-over-mandrel tube; ornamental and mechanical tube; welded and seamless pipe in nominal sizes and schedule walls.
Aluminium
Sheets, plates, bar in all sections, and the full structural extrusion range — angle, channel, tube, beam and pipe.
Copper and brass
Free-machining brass rod, flat, square and hexagon bar; cartridge brass sheet and plate; copper sheet and bar.
Tool steel
Drill rod and precision ground flat stock in the air, oil and water hardening grades.
Expanded metal and grating
Standard (raised) and flattened expanded metal; welded bar grating panels.
Miscellaneous
Spring steel strip, shim stock in steel, stainless and brass, metal framing strut, adjustable basement columns, and the assorted specials that every stockholder carries.
Processing operations
The standard service-centre operations that turn any of the above into a part: sawing and mitering, shearing of sheet and plate, punching, brake forming, and oxyfuel, plasma or laser burning. What each can and cannot hold is covered on the service centre page.
A note on certification
Material certification is a document, not a property. A mill test report records the chemistry and mechanical test results for the specific heat a piece came from, and it travels with the material. If a job requires certified material, the requirement has to be stated at the point of order — once a bar has been cut off a rack and mixed with others, its heat number is gone and no test afterwards can restore the traceability.
