The Steel Dovetail Profile Roof Floor Deck Roll Forming Machine is an automated specialized equipment that adopts continuous cold bending forming technology, designed for mass manufacturing of dovetail (necking) type floor support plates for steel structure buildings. The whole machine consists of a hydraulic unwinding machine, a leveling feeding mechanism, multiple precision roll forming units, a servo positioning punching system, a hydraulic cutting device, a finished product conveying and stacking line, and a PLC touch screen control system; Hot/electroplated galvanized steel strips with a thickness of 0.7-1.5mm can be processed into dovetail shaped floor slabs at room temperature in one go, without the need for high-temperature welding, fully preserving the strength of the steel and anti-corrosion coating. It is the core processing equipment for achieving “steel-concrete composite floor slabs” in modern steel structure buildings, with dual functions of formwork and stress.
Why choose us?
1.Enhanced grip strength: After the produced dovetail board is combined with concrete, it forms a bite structure similar to a “mortise and tenon”, greatly improving its shear resistance and meeting the needs of most scenarios without the need for additional bolts.
2.Better fire and corrosion resistance: The closed or tapered design allows the ribs to be better wrapped by concrete after pouring, with a fire resistance limit of more than 2 hours and longer lasting protection from the galvanized layer.
Application scenarios:
• Tall buildings and commercial complexes:
The floor structure of office buildings, hotels, and apartments, with swallowtail floor slabs as permanent templates, can reduce the process of formwork support and removal, accelerate concrete pouring and subsequent construction progress.
• Industrial plants and warehousing logistics:
The floor system of heavy-duty plants, three-dimensional warehouses, and cold chain centers combines high-strength load-bearing and good impact resistance, suitable for heavy equipment and frequent operational loads.
• Public buildings and prefabricated projects:
exhibition centers, sports halls, schools, hospitals, as well as light steel villas and modular integrated buildings, can be accurately connected with steel structure beams and columns to improve the assembly rate and shorten the overall construction period.
• Municipal and infrastructure:
subway vehicle depots, supporting buildings for pipe galleries, auxiliary floors of airport terminals, and the anti-seepage and overall stress performance of dovetail structures can cope with complex working conditions and long-term usage needs.

Core Features:
1.Swallowtail lock, high forming accuracy:
Modular steel roller system+PEM optimized design, combined with intelligent correction and synchronous control, the plate height/wave distance/effective width tolerance is controlled within ± 0.2mm; The dovetail joint structure can greatly improve the interlocking degree with concrete, prevent leakage during pouring, and ensure good straightness and no warping or twisting of the finished product. The cross-section is free of burrs and does not require secondary treatment.
2.Full process automation, efficient cost reduction:
the forming speed can reach 15-25m/min, automatically completing unwinding, leveling, punching, forming, cutting, and stacking; Single shift production capacity far exceeds traditional processes, with a material utilization rate of over 98%, reducing labor costs and board losses; Support continuous switching between long board sizing and batch small-sized boards.
3.Flexible changeover, strong customization:
quick mold replacement+one click parameter adjustment, compatible with various specifications of dovetail floor slabs; Customize plate ribs, hole diameter, hole spacing as needed, adapt to pipeline pre embedding, shear nail welding; The surface of the roller is coated with hard chromium (HRC 58-62), which is wear-resistant and durable, suitable for long-term continuous production.
4.Safe, durable, and easy to operate:
using well-known brand electrical and hydraulic components, equipped with overload protection, automatic lubrication, and emergency shutdown systems; The whole machine adopts H-shaped steel welded frame, with sufficient rigidity and low vibration; Visual touch screen operation, automatic fault alarm prompt, no need for professional team for daily maintenance.
