Under the background of the rapid development of global infrastructure expansion and warehousing and logistics, arch roof span buildings are rapidly popularizing in overseas markets with their outstanding advantages such as large span, fast construction and low cost.  As a continuous production line integrating rolling, roll forming, automatic cutting and biting, K span roll forming machine can directly process rolled galvanized steel coils into arched corrugated plates with reinforcement ribs, saving intermediate warehousing and secondary transportation links, and pressing from the source Shrink the construction period and comprehensive cost.

Product Profile

Product Process

1. Decoiling and leveling: The steel coil is automatically fed by the hydraulic decoiler and enters the leveling device to remove residual stress to ensure that the plate surface is flat and the feeding is stable;
2. Roller forming: the flat plate material is gradually roll forming through multiple sets of rollers in turn, and is pressed into a corrugated plate with a trapezoidal or V-shaped reinforcement rib. The depth of the arch rib and the plate shape are precisely controlled by the roller;
3. Automatic fixed-length cutting: The PLC numerical control system automatically calculates the arc length according to the preset span, and the cutting device cuts with the movement during the forming process to ensure that the incision is flat and the size is consistent;
4. Arch plate forming and bite: The cut corrugated plate is roll formed into an arch plate by the supporting K span roll forming machine, and is tightly bonded with the adjacent plate through the bite machine to form a self-supporting arch structure;
5. On-site lifting and installation: The formed arch plate is hoisted to the roof position in sections, and the whole cross-house panel can be closed without bars and supporting components.

From the perspective of the workflow, the operation logic of the K span roll forming machine is clear and reliable: after the steel coil is automatically decoiled and leveled, the flat material is pressed into a corrugated plate with a trapezoidal or V-shaped reinforcement rib through multiple sets of rollers. Then it is automatically cut into an arch plate according to the set span. With the arch plate forming and buckling equipment, the K span roll forming machine can complete the whole process of production from steel coils to full-span arched roofs at the construction site.

Core competitive advantage

In the actual project, the competitiveness of K span roll forming machine is reflected in three aspects:

First, high forming accuracy, multi-channel gradual forming ensures that the arch plate size is consistent, and the assembly bite is tight; second, the degree of automation is high. Second, the whole machine is compact, easy to transport, and can be quickly deployed at the overseas project site. Third, the use of arch plate system can save the lots of bar and most of the support components, which significantly reduces the amount of steel and comprehensive cost compared with the traditional steel structure.

Typical application scenarios

Judging from the application scenario, the coverage of K span roll forming machine is very wide, covering almost all types of buildings that require large-scale, fast and low-cost closed spaces:

Warehousing and Logistics Center

Modern logistics warehousing requires a large-span column-free space to facilitate forklift operation and shelf layout. The arched roof does not need internal columns, which can realize a single-span unobstructed continuous operation area, which is the most cost-effective roofing scheme.

Gymnasium and Convention and Exhibition Center

The arched roof has smooth lines and beautiful shape. With a large span design, it can create an open indoor space. At the same time, the construction cost is much lower than that of steel structure venues of the same specification, which is favored by the owners.

Agricultural greenhouses and breeding facilities

Agricultural production is highly sensitive to cost. Arched panels have good insulation performance and fast construction speed. They can quickly build large-scale planting and breeding houses at low cost. They are widely used in Australia, South America and other markets.

Mining areas oil fields and temporary facilities

In remote operation areas, transportation and lifting conditions are limited. K span roll forming machine can transport the equipment to the site for direct forming and use with construction, which is especially suitable for rapid deployment scenarios such as barracks, machine repair workshops and temporary buildings for emergency disasters.

Overall, with the continuous growth of demand for assembly and low-cost construction in the overseas market, K span roll forming machine has become an indispensable core equipment in the arched construction production line. It uses a continuous production line to simplify the construction of complex steel structure roofs into the standard process of “steel roll-in, arch plate-out”, bringing the triple benefits of speed, cost and quality to contractors.
