Floor Deck Forming Machine: Types, Profiles & Speed Grade Comparison

Description:A floor deck forming machine is a specialized cold roll forming equipment designed to process galvanized steel coils into structured metal floor deck panels for steel structure buildings, high-rise apartments, commercial plazas, and industrial workshops. It realizes continuous feeding, roll forming, punching, cutting, and automatic output in one process, featuring stable molding, high dimensional accuracy, and low production cost.

To help global customers select the most suitable equipment according to production scale, budget, and processing demands, we fully elaborate on the complete classification, mainstream deck profiles, and detailed configuration differences, advantages and disadvantages of low-speed, medium-speed and high-speed floor deck forming machines in this article.

Full Classification of Floor Deck Forming Machines

Floor deck forming machines can be classified from three core dimensions: structural deck type, production automation level, and operating speed grade, covering all mainstream models in the global construction steel market.

Classification By Deck Panel Structure

This is the most common classification standard, corresponding to different building load-bearing and construction scenarios:

Composite floor decking panel (Combined floor decking panel)

Composite floor slab = profiled steel sheet (base slab) + cast-in-situ reinforced concrete – both share the load; the steel sheet serves both as formwork during the construction phase and as the permanent structural load-bearing layer; this combined system is often referred to as a composite floor slab.

Composite floor decking panel: Steel plates participate in load-bearing; permanent load-bearing components

Non-combined floor decking panel (formwork type): The steel plate serves solely as a formwork; the concrete bears all the load-bearing capacity; the panel can be removed or retained at a later stage.

Form Deck (Non-composite Floor Slab / Template-Based Floor Slab)

Form Deck = Permanent Template Floor Slab (Non-Composite Deck)

This serves solely as the permanent form work for the concrete; upon completion, the steel plate does not participate in the subsequent load-bearing process – all loads are borne independently by the reinforced concrete floor slab. The slab surface exhibits no indentations or embossments; no shear interaction occurs between the steel plate and the concrete, and thus no composite load-bearing system is formed.

Floor Deck (Steel Floor Slab / Floor Support Slab)

Floor Deck is a general term for floor decking systems and encompasses two main subcategories: Composite Deck (composite floor decking with shear embossment) and Form Deck (form work-type floor decking without embossment); these must be cast with concrete and are intended solely for floor slabs; they cannot be used on roofs. 

Floor Deck Core Features

Intended for use as a floor surface; cast-in-place concrete shall be poured above it; the surface must not be left exposed as a standalone floor surface.

Temporary construction work platform: Once the steel plate installation is complete, the platform can serve as a construction access route without the need for full-scaffolded support.

Serves as a permanent concrete formwork system, eliminating the need for wooden formwork and demolding operations, thereby significantly reducing construction duration.

Hot-dip galvanized substrate – corrosion and rust protection – ideal for indoor flooring applications.

The rib groove space allows for the installation of water and electrical pipelines, facilitating the pre-installation of mechanical and electrical components.

Roof Deck (Roof Steel Slab / Roof Profiled Steel Sheet)

An independent roof structural substrate is installed above the steel beams without being cast with concrete; it serves to support the insulation layer, waterproofing membrane, and roofing materials. The steel plate features no embossments and does not participate in load-bearing interaction with the concrete. It offers excellent span support capability. The mainstream models – Bdeck (1.5 inches) and Ndeck (3 inches) – feature higher rib heights and longer unsupported spans compared to Formdeck, thereby reducing the number of required steel beams and lowering steel costs.

Various rib profiles available

A deck – shallow ribs, small span

B deck —Most versatile wide-web type

N Deck —Deep Rib,Extra-Large Span

F deck – narrow ribs, high stiffness

Dovetail Floor Deck（Re-entrant Composite Deck）

This is a closed-end composite floor slab system in which the upper edge of the rib is tapered inward, resulting in a dovetail-shaped cross-section; after concrete is poured, the concrete fits into the dovetail groove, ensuring a secure bond between the steel plate and the concrete – constituting a composite load-bearing floor slab system. 

Classification By Automation Degree

Semi-Automatic Floor Deck Machine: Manual feeding, manual parameter adjustment, fixed-length cutting. Simple structure, low price, suitable for small processing factories and intermittent production.

Fully Automatic Floor Deck Machine: PLC touch screen intelligent control, automatic feeding, fixed-length forming, automatic punching and cutting, one-key operation. Supports continuous 24-hour production, saving labor costs.

Multi-Model Quick-Change Floor Deck Machine: Upgraded fully automatic model, realizing stepless adjustment of rib height and bottom width without replacing rollers, compatible with multiple deck profiles, high equipment utilization.

Classification By Operating Speed (Core Classification)

Divided into low-speed, medium-speed and high-speed models, with obvious differences in configuration, production efficiency, applicable materials and investment cost, which is the key basis for customer selection:

Low-speed machine: 5–10 m/min

Medium-speed machine: 12–18 m/min

High-speed machine: 20–30 m/min
