Short answer:<\/strong> A B deck roll forming machine produces the 1.5 inch structural deck that US commercial roofs and composite floors are built on. It forms 36 inch panels from 22 to 16 gauge galvanised coil at 12 to 30 m\/min, with a nesting sidelap that locks panel to panel on site.<\/p>\n\n

A B deck roll forming machine is a dedicated line, not a converted roofing mill. Six wide ribs at 6 inch centres, a 1.5 inch rib depth, and geometry stiff enough to carry wet concrete between joists. Every module on the line follows from those numbers.<\/p>\n\n

What the B Deck Roll Forming Machine Produces<\/h2>\n\n

B deck is a wide rib structural panel. The rib is 1.5 inch deep, the pitch is 6 inch on centre, and six ribs give 36 inch of coverage. Top flange 3.5 inch, bottom flange 2.5 inch, which is why insulation boards sit flat instead of sagging between ribs.<\/p>\n\n\n\n

The 3.5 inch flange carries the insulation, the 1.5 inch rib carries the moment, and the sidelap carries the diaphragm shear. A B deck roll forming machine that misses any of the three ships deck that fails inspection.<\/p>\n\n

B Roof Deck and B Floor Deck Come Off the Same Line<\/h2>\n\n

Roof and floor deck share one profile. Dimensions are identical. What changes is coil thickness, sidelap detail, and whether panels carry embossments for composite action.<\/p>\n\n\n\n

A floor deck order pushes buyers toward a heavier B deck roll forming machine. Going from 0.8 mm to 1.5 mm adds load to every station, so shafts, bearings and the shear cylinder all step up. Budget a B deck roll forming machine for the thickest coil, never the average.<\/p>\n\n

If your book mixes deck with deeper structural profiles, the steel floor deck roll forming machine<\/a> page covers 75 mm composite sections. Buyers comparing floor systems should read the mezzanine floor roll forming guide<\/a> before locking a rib height.<\/p>\n\n

Line Configuration from Coil to Bundle<\/h2>\n\n

A standard B deck roll forming machine runs on one straight axis. Coil enters at one end, formed panel leaves at the other, and every module between is sized for 1.5 mm steel at full width.<\/p>\n\n\n\n
Module<\/th>Standard specification<\/th>What it does<\/th><\/tr><\/thead>\n
Hydraulic uncoiler<\/td>10 ton, with coil car<\/td>Pays off coil under controlled tension<\/td><\/tr>\n

\n\"Complete\n
A complete line: uncoiler, 26 forming stations, hydraulic shear and runout table in one axis.<\/figcaption>\n<\/figure>\n\n

Three modules decide whether the line earns money. The shear decides speed, the stacker decides labour, the uncoiler decides how much coil handling fills each shift.<\/p>\n\n

Technical Parameters<\/h2>\n\n

These numbers hold for a standard B deck roll forming machine. Anything outside them is a custom build, and we quote it as one.<\/p>\n\n\n\n

The 90 mm shaft is what buyers under-specify most. A 1.5 mm floor panel at 36 inch width puts real torque into the shaft, and a 70 mm shaft deflects enough to show in rib height.<\/p>\n\n

Speed, Output and What Limits Them<\/h2>\n\n

Speed on a B deck roll forming machine follows the cutoff, not the motor. The forming section can always outrun the machine’s ability to stop a moving panel.<\/p>\n\n
