Steel Bar Truss Floor Decking Sheet Roll Forming Machine

Steel Bar Truss Floor Decking Sheet Roll Forming Machine

The Steel Bar Truss Floor Decking Sheet Roll Forming Machine is a specialized piece of industrial equipment engineered to produce the galvanized base plates used in modern steel bar truss floor decking systems. In contemporary construction, particularly for high-rise steel structures, the steel bar truss floor deck has become the preferred choice over traditional formwork due to its superior load-bearing capacity and construction efficiency. The base plate produced by this machine acts as the permanent bottom formwork, providing a stable platform for the truss welding and subsequent concrete pouring. This equipment is designed to meet the rigorous standards of modern structural engineering.

The machine features a robust, welded steel frame, characterized by its distinctive red and blue industrial finish, ensuring high rigidity and long-term durability under continuous production loads. The forming section consists of precision-engineered rollers fabricated from high-grade forged steel, which undergo meticulous heat treatment and chrome plating to achieve exceptional hardness (HRC 45-50°). These rollers are designed to handle the narrow strips of galvanized steel, creating subtle yet critical ribs and lips that ensure the structural integrity of the base plate. Unlike wide-profile floor deck machines, this line focuses on concentrated forming accuracy for the truss integration process. The stable frame geometry prevents vibration and misalignment during high-speed operation.

The production process begins at the decoiler, where the galvanized steel strip is fed into the guiding station. The material then enters the multi-stage roll forming section, where it is gradually transformed into the required profile through a series of cold-bending passes. One of the standout features visible in the technical assembly is the precision-guided material entry, which ensures that the narrow strip remains perfectly centered throughout the forming sequence. The machine utilizes a high-performance drive system, often paired with heavy-duty chains, to maintain a consistent forming speed and prevent material distortion. This progressive forming method minimizes internal stress in the finished metal profile.

A critical component of this machine is the hydraulic cutting station, which features a custom-profiled cutting die. As seen in the close-up images, the cutting blade is precisely shaped to match the cross-section of the truss base plate, providing clean, burr-free cuts at programmed lengths. This hydraulic system is integrated with a centralized PLC (Programmable Logic Control) unit, which allows operators to input specific quantities and lengths via an intuitive touch-screen interface. This automated approach significantly reduces manual labor and material waste, allowing for seamless integration into a larger truss welding production line. The accuracy of the length measurement system is essential for subsequent welding steps.

The base plates produced by the Xinnuo Truss Decking Sheet Machine are essential for the construction of high-performance composite floor slabs. These systems are widely used in commercial skyscrapers, large-scale industrial warehouses, stadiums, airports, and residential steel-frame buildings. By using a truss floor deck, contractors can achieve longer spans with fewer temporary supports, dramatically accelerating the construction timeline. The high precision of the Xinnuo machine ensures that every base plate meets the tight tolerances required for high-speed automated truss welding, which is critical for maintaining structural safety standards in major public infrastructure projects.
