The K Span Machine produces self-supporting arch roof panels that eliminate the need for beams, purlins and interior columns, creating larger unobstructed working areas while reducing overall building costs.
The machine can be transported directly to the construction site, allowing roof panels to be produced close to installation. This minimizes transportation challenges associated with extra-long roofing sheets.
From factories and warehouses to aircraft hangars, livestock farms and emergency buildings, the K Span Machine delivers flexible arch roof solutions for projects requiring wide spans and long service life.
This K Span Machine is designed with an integrated forming and cutting layout that improves production continuity while maintaining excellent forming accuracy. Its rigid frame structure minimizes vibration during continuous operation, making it ideal for manufacturing large-span self-supporting roof panels.
Panels produced by the K Span Machine feature precise seams, uniform curvature and outstanding structural integrity. The finished roof system delivers large clear spans without beams or columns, making it suitable for industrial, agricultural and commercial buildings.
The secondary curving unit allows the K Span Machine to produce smooth and uniform arch profiles with consistent curvature. Accurate secondary forming ensures excellent structural performance and simplifies on-site installation.
The K Span Machine adopts heat-treated Cr12MoV cutting blades that provide clean cutting edges, high hardness and excellent wear resistance. This design helps maintain stable cutting quality even during extended production cycles.
XINNUO Roll Forming Machine has specialized in designing and manufacturing K Span Machine solutions for more than 30 years. Every K Span Machine is engineered according to project span, local wind load, material specification and installation requirements rather than relying on fixed configurations.
Unlike standard equipment suppliers, XINNUO focuses on complete project solutions. Our K Span Machine can be integrated with hydraulic decoilers, automatic feeding systems, panel curving equipment and on-site installation accessories, enabling customers to build efficient production lines from coil to finished arch structure.
Backed by extensive manufacturing experience, advanced CNC machining, strict quality inspection and continuous engineering innovation, XINNUO delivers reliable machines that serve industrial buildings, warehouses, agricultural facilities, sports halls and logistics centers across more than 150 countries.
Whether you require a standard K Span Machine or a fully customized solution for special spans and local building codes, our engineering team provides professional support from design to commissioning.
It is widely used for warehouses, factories, logistics centers, aircraft hangars, agricultural buildings, gymnasiums, storage facilities, military buildings and temporary construction projects requiring large column-free spaces.
Yes. We customize every K Span Machine according to your required building width, arch height, material thickness, wind load and local construction standards to ensure the best structural performance.
The machine can process galvanized steel, Galvalume steel and aluminum coils in various thicknesses depending on project requirements.
A self-supporting arch roof eliminates beams, purlins and interior columns, reducing structural steel consumption while providing larger usable interior space and faster installation.
Yes. The K Span Machine can be moved to project locations so panels are manufactured near the installation area, reducing transportation costs and handling risks for extra-long roof panels.
XINNUO can provide a complete production solution including:
