What a construction roll forming line actually does

Every machine on this page does the same three things: uncoil flat steel, bend it through a sequence of roll stands, and cut it to length. What changes is the profile — and the profile changes the machine. A purlin line running 5 mm coil carries several times the shaft load of a roof sheet line running 0.4 mm, so stand count, shaft diameter, drive power and cut-off design all move with the material.

Beli RollForming has built cold roll forming equipment since 2005. This catalogue covers 25 machine types for construction and steel structure work, grouped below by what they produce rather than by model number.

Purlin lines: the structural skeleton

Purlins are the horizontal members that carry roof and wall loads between frames. They are the highest-volume profile in most steel building plants, and usually the first line a new factory orders.

C purlins are rolled from 1.5 to 5.0 mm coil. Z purlins use the same thickness window with a web of 80 to 350 mm and a flange of 35 to 80 mm. The lapped connection between Z sections is what lets a roof span further without a deeper section, which is why Z outsells C at long spans and why both profiles stay in every catalogue.

If you sell both, an interchangeable C/Z machine removes the second line. On the current BELI design the change from C to Z takes about two minutes and is made through the control, not by swapping roll sets by hand.

Multibeam (omega) lines run a wider window again: web 100 to 450 mm and flange 60 to 100 mm, adjustable without new rolls across the standard sizes. They are bought by plants serving cladding, mezzanine and secondary framing work rather than pure structural purlins.

Roof and wall sheet lines: the face of the building

Sheet profiles are regional products. A line built for one market rarely sells its output in another, so this is the part of the catalogue where the destination decides the specification.

  • Klip-Lok — concealed-fix roof sheets for Australia, in 700 mm and 406 mm cover widths.
  • IBR — the South African standard sheet, in continuous use there since 1958.
  • Box profile — the UK industrial and agricultural sheet, and the profile most often specified on British portal frame buildings.
  • Corrugated — the widest-selling sheet in the world. Our line changes sheet width by adjusting the feed guides rather than changing moulds, so one machine covers a family of widths.
  • Widespan and standing seam — long spans and concealed fasteners for architectural roofs where the fixing line must not show.
  • Double layer — two different profiles on one machine base, for plants that sell a roof and a wall sheet from the same floor space.
  • AG panel — the US agricultural panel, with a deep rib and a wide flat pan.

Most sheet lines run 0.2 to 0.8 mm coil and are limited by cut-off and stacking rather than by the forming stands. If you are planning output per shift, price the run-out table and the stacker together with the mill.

Tile profiles: a regional product too

Metal tiles copy the look of clay and concrete while weighing a fraction of them. Glazed tile lines on the current design reach up to 6 m/min, steel tile profiles reach a depth of 30 mm, and the Monterey V1100 is the profile most often specified for residential roofs in North and South America. All of them are built to the buyer's drawing, because tile profiles are effectively brand products: a millimetre of rib height is a different product on the roof.

Deck, framing and trim

Three smaller families complete the range. Deck lines produce B deck for the US structural market and composite floor deck from coil up to 2.0 mm with yield strength up to 550 MPa. Light steel framing lines produce studs and tracks for LSF construction, and one machine can cover ceiling channels, wall angles, POP and furring channels by changing the roll set. Trim lines cover ridge caps and edge details — small parts, but the first thing a building owner sees on the roof.

How to specify a construction line

Four answers decide most of the quotation, and giving them up front saves a round of revisions. First, the profile drawing: dimensions, rib geometry and hole positions. Second, the steel you will actually buy, not the grade you would like to buy — a 550 MPa coil on a mill specified for mild steel will distort the section and wear the rolls early. Third, target output per shift, which decides whether you need automatic stacking or a manual run-out table. Fourth, the coil size and weight your crane or forklift can handle, because a 10 t uncoiler is useless if nothing on site can lift the coil onto it.

If you are still comparing line architectures, our guide to choosing, operating and maintaining a roll forming machine covers the same decisions from a wider angle. For coil purchasing and yield planning, the metal coil calculator works out how many metres a coil will yield before you commit to a tonnage.

Frequently asked questions

What is a construction roll forming machine?
A construction roll forming machine turns flat steel coil into a finished building profile: a purlin, a roof or wall sheet, a metal tile, a floor deck panel or a light steel framing member. The coil is uncoiled, formed through a series of roll stands, punched where the profile needs holes, and cut to length in one continuous pass. No heating and no welding during forming.
What steel thickness can these lines run?
The catalogue spans 0.2 mm to 5.0 mm, but no single line covers that range. Roof and wall sheet lines run roughly 0.2 to 0.8 mm, C and Z purlin lines 1.5 to 5.0 mm, and floor deck lines up to 2.0 mm with yield strength up to 550 MPa. Running a line far outside its comfortable window is how plants end up with distorted sections and worn rolls.
Can one machine produce both C and Z purlins?
Yes. An interchangeable C/Z purlin machine produces both profiles from one base, and on the current BELI design the change is made through the control in about two minutes. It is not the right answer for every plant though: if you sell very high volumes of one profile, a dedicated line usually runs faster and needs less operator attention.
What is the difference between a purlin line and a roof sheet line?
Load. A purlin line forms 1.5 to 5.0 mm structural steel, so it needs larger shafts, more drive power, more stands and a heavier cut-off. A roof sheet line forms 0.2 to 0.8 mm sheet, where the forming load is small and the real constraints are surface finish, cut-off quality and stacking speed. The two are not interchangeable even when the profile drawing looks similar.
Which roof profiles are regional?
Most of them. Klip-Lok 700 and 406 are Australian, IBR has been the South African standard since 1958, box profile is the UK industrial and agricultural sheet, B deck is a US structural deck, and AG panel serves US agricultural buildings. Buying a line for the wrong regional profile is the most expensive mistake in this category, because the finished sheet simply has no market.
How fast do these lines run?
It depends on the profile and the cut-off, not just the mill. Glazed tile lines on the current design reach up to 6 m/min, and sheet lines generally run faster than heavy purlin lines because the material is thinner. In practice most plants are limited by the run-out table, the stacker or the operator, so price those with the mill rather than after it.
What information do you need to quote a line?
A profile drawing with dimensions, the steel grade or yield strength you intend to buy, your target output per shift, and the coil size and weight you can handle. Add the regional standard you are selling into, because that decides the profile set. With those five items we can propose a configuration, estimate cycle time and give a price range instead of a catalogue number.
