Short answer: The floor deck roll forming machine specifications that matter are, in order: formed material gauge (typically 0.4–1.2 mm), coil width the decoiler accepts (up to ~1250 mm), the deck profile you need (open/closed/tapered, wave height in tens of mm), forming stations and shaft diameter (28 stations with ~105 mm solid shafts is a heavy-duty reference), and line speed plus cut system (hydraulic length cutting with PLC batch control). A real heavy-duty reference line runs GI coil 0.4–1.2 mm × ~1000 mm wide through 28 roller stations at 15–20 m/min with automatic decoiler, hydraulic punching and automatic stacking — forming composite-floor deck sheets several meters long in one pass.
This guide explains each specification in plain language and gives you a benchmark sheet to compare against any quote.
Why floor deck machines are different from roof sheet machines
Floor decking (bondek / metal deck) is a structural product: the profiled sheet acts as both formwork and, in composite design, tensile reinforcement for concrete slabs in high-rise and industrial buildings. Because it carries load, the forming line must handle thicker, wider strip with higher stiffness demands than a roof sheet line — which is why floor deck machines are built heavy (welded 350H steel frames, large solid shafts) and form deep multi-rib waves in one pass.
Typical applications: super high-rise office buildings and hotels, large-span industrial plants and logistics warehouses, and prefabricated steel-structure housing.
The specification table you should benchmark
Real published example — ZTRFM Bondeck / Floor Decking Cold Making Machine (order code ZT116872238):
| Specification | Example value | Why it matters |
|---|---|---|
| Formed material | GI (galvanized), also color-coated coil | Must match your coil supply and building standard |
| Thickness | 0.4–1.2 mm | Thin end for decking sheets; check your project gauge |
| Coil width | Max ~1250 mm; formed width ~1000 mm (custom) | Wider coil = wider deck sheet, fewer seams |
| Decoiler | Hydraulic automatic decoiler | Loads coil with less downtime (sometimes included free in quote) |
| Forming stations | 28 roller stations | More stations = smoother gradual bending of deep profiles |
| Shaft diameter | 105 mm solid shaft | Rigidity at high load; prevents deflection and profile twist |
| Roller material | GCr15 bearing steel + 45# quenched, hard chrome plated | Wear life in continuous production |
| Machine frame | 350H steel, wall-plate welded | Structural rigidity for heavy strip |
| Drive | Double chain transmission | Torque delivery along the full forming length |
| Cutter | Automatic, Cr12MoV blades | Clean, scratch-free cuts with no deformation |
| Forming speed | 15–20 m/min | Depends on profile shape and material thickness |
| Motor power | Main ~5.5 kW + hydraulic ~4 kW | Total connected load for site power planning |
| Control | PLC automatic; set batch, length, quantity | The basis of ±length accuracy and unattended runs |
| Voltage | 380 V / 50 Hz / 3-phase (custom available) | Match your local supply |
| Machine size / weight | ~15000×1800×1600 mm; ~6 t | Factory space and floor loading |
| Included line | Feeding/uncoiling, servo leveling, hydraulic punching, forming, hydraulic length cutting, automatic stacking | Scope differences explain most price differences |
How to read each spec like a buyer
- Gauge range is the first filter. A machine that runs 0.4–1.2 mm cannot substitute for a heavy purlin line (1–3.2 mm) — match the machine to your decking gauge band.
- Deck profile depth and shape decide the tooling. Floor decks have specific rib/wave profiles and heights (tens of mm). The roll set is profile-specific; confirm the machine is tooled for the exact profile drawing you sell (open, closed or tapered decks).
- Stations × shaft tell you about rigidity. Deep deck profiles need many forming passes (28 stations in the example) and large solid shafts so the wave does not spring back or twist along the length.
- Hydraulic punching before/after forming matters. Floor decks often need embossments and shear stud patterns; confirm the punching stations included cover your drawing.
- Line scope, not machine name, is the price. Two "floor deck machines" at the same price can differ by the decoiler, leveler, punch, cutter type and stacker included. Itemize before comparing.
When a floor deck machine is the wrong buy
- You sell roof sheeting, not structural decks → a roof sheet line (0.18–0.8 mm, lighter frame) is cheaper and faster for that job.
- You only produce short panels by hand or press brake → volume does not justify a full forming line.
- Your building code needs a deck profile outside the machine's tooling range → confirm the roll set can be made to your drawing before ordering.
7 questions to ask every floor deck supplier
- What exact gauge and coil width does this line guarantee — not advertise?
- Is the tooling made to my deck profile drawing, including embossments and hole patterns?
- How many forming stations and what shaft diameter — and what roller steel grade?
- Which cut system and what real length accuracy in production?
- What is included in the price (decoiler, leveler, punch, stacker) and what is extra?
- Which PLC/HMI and is remote assistance available after shipment?
- Can I see a factory test run of my profile before shipment?

ZTRFM (zt-rfm.com) is a roll forming sourcing center operated by Zhongtuo Roll Forming (Hebei) Co., Ltd. Deck steel and composite slab references commonly cited include ASTM A653 (zinc-coated sheet) and the composite-deck design standard applicable in your market (e.g. SDI in the US); ask your supplier which standard your profiles are made to.
Frequently Asked Questions (FAQ)
What gauge can a floor deck roll forming machine run?
Heavy-duty floor deck lines typically run 0.4–1.2 mm galvanized or color-coated coil; confirm the exact guarantee on your model and profile.
What is a bondek machine?
A floor decking (bondek) cold forming line that rolls deep multi-rib structural deck profiles from steel coil in one pass — used as formwork and composite reinforcement for concrete floors.
How fast is a floor deck forming line?
Typical forming speed is 15–20 m/min, depending on profile shape and material thickness; speed is not the main selection criterion for structural decks.
How many forming stations do floor deck machines have?
Heavy-duty reference lines use ~28 roller stations with large solid shafts (e.g. 105 mm) to bend deep deck profiles gradually and accurately.
What is included in a complete floor deck line?
Typically feeding/uncoiling (hydraulic decoiler), servo leveling, hydraulic punching, the forming main unit, hydraulic length cutting and automatic stacking — confirm scope item by item.
Can one machine run different deck profiles?
Only if the roll tooling is changed or the machine is specified multi-profile; each deck profile drawing needs its own roll set. Confirm before ordering.
