[Company Profile]
Pulei Steel Industry specializes in floor steel deck, galvanized corrugated steel sheet, and color steel tiles.CZ steel, aluminum magnesium manganese alloy roofing systems, and related accessories are specially processed and manufactured. After fierce market baptism, the company now owns nearly 30 floor deck production lines, nearly 60 sets of color steel tile and aluminum magnesium manganese profiled sheet production equipment, and 4 CZ steel production lines. The floor deck processing thickness ranges from 0.7mm to 3.5mm, covering open, closed, and reduced gap floor decks. Color steel tiles include roof tiles, wall tiles, vertical locking edge roof systems, arched color steel tiles, etc., with thickness ranging from 0.3mm to 1.2mm, capable of processing custom special color plates and aluminum profiled plates. Our company also processes and sells auxiliary materials for steel structures, such as color steel downspouts, gutters, welding nails, and steel structure brackets. Whether in terms of market sales, equipment ownership, or processing capabilities, our company has become a strong player in the steel structure material production and processing industry. Additionally, we can design, develop, and process new sheet profiles and new products according to market requirements.

【Product Advantages】
Our production facility is staffed with a highly qualified team, and products are manufactured strictly according to standards.
Reinforced truss floor decks not only eliminate the hassle of construction processes but also offer the advantages of cast-in-place concrete slabs, such as excellent overall integrity, high rigidity, and good fire resistance, as well as the benefits of profiled steel deck floors, including no need for formwork and rapid construction. Furthermore, they can achieve larger spans through varying the truss height and steel bar diameter. As a mature new technology, truss floor decks are extensively used in both domestic and international construction and hold great potential in multi-story and high-rise buildings.
Maximize the mechanical properties of both steel and concrete materials.
The ribbed surface of the profiled steel sheet enhances the bonding between the deck and concrete, creating a cohesive unit. With the addition of stiffeners, the deck plate gains load-bearing capacity.
The corrugated steel sheets themselves provide a smooth ceiling surface for concrete floors.
The fire resistance of the floor deck: The special design of the closed rib shape of the floor deck allows the steel deck ribs to be completely encased in concrete, resembling the rebar in cast-in-place concrete slabs, which has been actually verified through a two-hour fire resistance test.
Installation Matters
Color-coated steel sheet bending machine and place pads of appropriate thickness.Ensure that the top and bottom molds fit together with even gaps around all four sides, and the distance between the top and bottom molds is equal to the thickness of the required wafer. Then, using the top mold as a reference, rotate the workbench and install the remaining five sets of bottom molds. Only after all the top and bottom molds are installed can the press machine be started for wafer pressing. By the way, it's Children's Day! Pressing machines are usually equipped with a set of lubrication equipment. While the machine is running, it automatically oils all bearing supports, transmission gear mechanisms, and guide rails.
Enhance concrete curing.Factory Notes for 300 Closed Deck Forming Machines: The spacing of steel column grids is generally 5~9.0m x 8~15m, with secondary beam spacing at 3m. However, the cutting length of the deck plates is 4.97~8.97m, making transportation and installation challenging, especially for hoisting deck plates with a vertical arc area. It is difficult to pass through the narrow space between secondary beams from top to bottom, which also disrupts the normal welding sequence of secondary beams.
Due to the difficulty in observing the flanges of the secondary beams after the roof deck is laid.#Reposition the centerline and flange width of the secondary beam back to the center of the main beam#, and when fixing the dowels, reposition the centerline and flange width of the secondary beam to the floor deck on the secondary beam surface. This saves the amount of steel and concrete used. Accommodate the straight-line machine. After the steel floor deck is installed, it can be used as a construction platform. Additionally, as it does not require props: the ribbed surface of the shaped panel creates a significant bond between the floor deck and the concrete.
Estimated: The flatness of the board should be less than 3mm, with no obvious unevenness, warping, or deformation. The galvanized layer should exceed 120g/m², and there should be no scratches, marks, or remaining slag from silver brazing. Weld points should be secure. The surface should not have any contaminants that could affect cement curing.
The load-bearing performance of concrete slabs, where the self-weight of the concrete slab is entirely supported by the reinforcing steel, avoids tensile stresses within the concrete. During use, the concrete in the negative moment and positive moment areas experiences significant tensile stresses, which reduces crack widths. The presence of galvanized steel sheets prevents cracks from forming under the slab, enhancing its performance and durability. The reinforcing steel in the floor deck is encased in concrete, providing reliable fire resistance. Experiments show that the slab thickness isAt 100mm thickness (with a corresponding steel truss height of 70mm), the耐火 duration is 1.67 hours; no fire protection is required for galvanized steel plates.
