01.Classification of Floor Deck Roll Forming Machine
The floor bearing plate, also known as profiled steel plate or steel bearing plate, is the core material for floor construction in steel structure buildings. The industry primarily classifies it based on "plate configuration and forming process," dividing it into three main types: open-type, concave (swallow-tail) type, and closed-type. Each type exhibits significant differences in performance and application scenarios. The specific classifications and characteristics are as follows:

Composite Floor Deck Roll Forming Machine: Precision Production Line for Steel-Concrete Composite Slabs
The composite floor deck roll forming machine is a heavy-duty cold roll forming line that converts galvanized or galvalume steel coil into high-strength profiled floor deck sheets. These decks act as permanent formwork during concrete pouring and, after curing, work compositely with the concrete slab to provide tensile strength, stiffness and fast multi-story construction. In international markets the equipment is also searched as a composite metal deck roll forming machine, steel floor decking roll former, concrete deck sheet making machine or structural floor deck production line.
It is the core machine for steel structure contractors, precast and composite slab factories, high-rise building material suppliers and industrial flooring manufacturers who need consistent rib geometry, reliable concrete bonding and high daily output.

Why Composite Floor Deck Sheets Dominate Modern Construction
Composite steel decking replaces traditional timber formwork in most medium- and high-rise projects. The rolled sheet becomes a working platform immediately after it is fixed to the steel beams, allowing following trades to start earlier. When concrete is poured, the embossed ribs and optional shear-stud holes create mechanical interlock between steel and concrete, forming a single composite floor system.
Main advantages for the buyer and end user:
Faster floor cycles – no temporary formwork removal, less shoring, simultaneous upper-floor work
Strong composite action – embossing patterns improve steel-to-concrete bond and slip resistance
Material savings – optimized rib design reduces concrete volume and overall dead load
Long spans – deep rib profiles allow wider beam spacing in commercial and industrial buildings
Fire and durability performance – when correct gauge and coating are used, decks suit fire-rated floor assemblies
Repeatable factory quality – every sheet has the same rib height, cover width and flatness

How the Composite Floor Deck Roll Forming Machine Works
Production starts with a heavy steel coil on the hydraulic or manual decoiler. The strip passes through the entry guide and multi-roll leveler, which removes coil curvature, camber and crossbow before forming. If the profile requires surface bonding lugs, the line uses an embossing station; if shear-stud holes, service holes or edge notches are specified, a punching press is installed before or after forming depending on tooling design.
The strip then enters the roll forming mill. Composite deck profiles are deeper and wider than roofing sheets, so the mill uses more stations and heavier rollers. Each station bends the flat strip progressively into trapezoidal, re-entrant or dovetail rib shapes without cutting the steel. Shafts, gearboxes and sidewall plates are sized for thick galvanized coil and high-yield material.
After forming, the panel runs to the cutting system. Most export lines use hydraulic post-cut or flying shear synchronized with the profile movement. The PLC controls length, quantity, batch production and optional punch timing. Finished sheets go to the run-out table, manual stacking area or automatic stacker.

Machine Configuration and Build Quality
A composite deck line is not a lightweight roofing machine. It is built for continuous industrial duty.
The frame uses heavy H-beam or thick welded plate construction with stress-relief treatment to prevent deflection during long runs. Rollers are machined from GCr15, Cr12 or 45# forged steel, heat-treated to high hardness and hard-chrome plated for wear resistance and a clean surface on coated coil. Shafts are precision-ground alloy steel supported in taper-bearing stands. The drive system is chain or gearbox type, often dual-motor on wide-deck lines to keep rib symmetry.
Embossing rollers are a key differentiator. Proper embossment geometry increases the shear grip between deck and concrete. Punching dies are guided and changeable for round holes, elongated holes, stud-hole patterns and edge notches. Cutting blades are Cr12MoV or equivalent, quenched and ground for burr-free ends. Control is PLC + HMI with encoder length feedback; advanced lines add remote diagnostics, recipe storage and automatic stacker integration.

Technical Scope for Export Orders
Each composite floor deck machine is customized to the buyer’s profile drawing. Standard configurable range includes:
Material: galvanized steel GI, galvalume GL, cold-rolled steel, occasionally stainless or aluminum-clad steel for special projects
Thickness: commonly 0.7–1.5 mm; heavy-duty versions up to 2.0 mm
Coil width: 1000–1250 mm typical, depending on effective cover width
Effective width: around 600–1000 mm depending on profile, e.g. YX51-250-750, YX76-305-915, YX75-200-600 and custom Losacero/B-Deck/N-Deck type sections
Rib depth: 50–80 mm standard; deep-deck versions up to 100 mm+
