This is the index the rest of the site hangs from: every standard mill form covered here, grouped by material family, with a one-line note on what the form is actually for. It follows the same six-family structure the original catalogue used, because that structure reflects how mills produce and how service centres rack — not how a search engine files things.

Hot rolled carbon steel
The largest family by far, and the default for anything structural, fabricated or painted. Detail on grades, tolerances and mill scale is on the hot rolled steel page.
- Steel angle — equal and unequal leg L-sections. Brackets, frames, trailer rails, lintels, edge protection.
- Steel flat bar — rectangular section. Straps, gussets, base plates, weldments, fabricated hinges.
- Steel square bar — solid square section. Shafts, keys, decorative work, machine bases.
- Steel round bar — solid round section. Pins, axles, shafts, weld studs, forged blanks.
- Steel square tube — hollow structural section. Posts, frames, racking, gates.
- Steel rectangle tube — hollow structural section with unequal sides. Beams in light framing where depth matters more than width.
- Steel round tube — hollow round section, welded. Handrail, rollers, light structures.
- Steel pipe — nominal-size, schedule-wall product. Fluid conveyance and, in heavier schedules, columns and posts.
- Steel channel — C-section, in bar-size, structural, and ship-and-car series. Frames, sills, machine bases.
- Steel beam — I-beam and wide flange. Spanning members; see I-beam for the section mechanics.
- Steel sheet — gauge-thickness flat product: hot rolled, hot rolled pickled and oiled, cold rolled, galvanised.
- Steel plate — flat product above sheet thickness, including structural, manganese, abrasion-resisting overlay and quenched-and-tempered high-strength plate.
- Steel floor plate — raised-pattern plate for walkways and trailer decks.
- Steel expanded metal — sheet slit and stretched into a diamond mesh; see expanded metal. Guards, walkways, screens.
- Steel rebar — deformed reinforcing bar for concrete.
- Steel threaded rod — all-thread, cut to length. Hangers, tie rods, adjustable assemblies.
- Metal framing strut — slotted channel strut systems for services support.
- Bar grating and basement columns — welded grating panels and adjustable steel columns.
- Drawn-over-mandrel (DOM) tube — cold drawn welded tube with excellent concentricity; see the DOM tubing note.
Stainless steel
Same form vocabulary, corrosion-resisting alloys, roughly four to six times the price. Grade selection is covered on the stainless steel page.
- Stainless angle, flat bar, square bar and round bar
- Stainless square tube and rectangle tube — see the stainless tubing reference
- Stainless pipe — schedule-wall, for process piping
- Stainless sheet and plate — see stainless sheet finishes and gauges
- Stainless floor (diamond) plate
- Stainless threaded rod — see stainless rod
Aluminium
Extrusions and rolled product. Alloy and temper matter more than they do in carbon steel; see the aluminium page.
- Aluminium angle and architectural angle — the architectural series has square corners and a uniform wall
- Aluminium flat bar, square bar and round bar
- Aluminium square tube, rectangle tube and round tube
- Aluminium pipe and channel
- Aluminium sheet and plate — see aluminium sheet
- Aluminium diamond (tread) plate
- Aluminium beam — American Standard channel and I-beam profiles
Cold finished steel
Bright, dimensionally tight bar for machining. Detail on the cold finished page.
- C1018 flat bar, square bar and round bar — the general-purpose cold drawn low-carbon grades
- 1045 turned, ground and polished round bar — medium carbon, straight and round enough to use as a shaft
- 4140 alloy flat bar and round bar — chromium-molybdenum, usually supplied heat treated
Tool steel
Bought by hardening behaviour. Detail on the tool steel page.
- A2, O1 and W1 drill rod — round, close-tolerance, annealed
- A2, O1 and D2 precision ground flat stock — rectangular, ground on all faces, annealed
Brass and copper alloys
Detail on the brass page.
- Brass flat bar, square bar and round bar — free-machining C360
- Brass sheet and plate — C260 cartridge brass, formable and solderable
Shim stock and miscellaneous
Thin gauge material in steel, stainless and brass, supplied in rolls or precut sheets for setting clearances, plus spring steel strip and the assorted specials that every stockholder carries and nobody catalogues consistently.
