This is a high-precision cold bending production line that integrates mechanical, hydraulic, and electrical control. The equipment uses galvanized steel plate, color steel plate or aluminum magnesium manganese alloy plate as raw materials, and directly produces trapezoidal roof tiles with double-layer hollow structure through continuous cold bending and rolling process.
Unlike traditional single-layer machines, Trapezoid Double Layer Roofing Sheet Machine For Building device cleverly combines two layers of substrates during the molding process to create a closed or semi closed “air chamber” inside the finished tile shape while maintaining a trapezoidal appearance. The entire line integrates automatic feeding, precise guidance, double-layer synchronous forming, fixed length cutting, and fully automatic stacking system, truly realizing unmanned and efficient production from coil to finished product.
Application scenario: Hidden champions of landmark buildings
● Large span industrial plants and logistics parks
The ultra large single slope length requires extremely high bearing capacity. The rigidity advantage of double-layer trapezoidal tiles can reduce the amount of purlins used and lower the overall steel structure cost. At the same time, the hollow layer effectively isolates machine roar and forklift noise, achieving a “noise reduction revolution” in the workshop environment.
● Airports, stations, and sports venues
Among these urban landmarks, roofs serve as both a barrier against wind and rain, as well as a carrier for showcasing grandeur. The smooth trapezoidal lines and the super long span capability of the double-layer structure perfectly support the designer’s grand idea and meet the requirements of a first level waterproof rating.
● High end villas and prefabricated residences
People’s pursuit of living comfort is endless. The insulation and rain suppression functions brought by double-layer tiles make metal roofs bid farewell to the cheap feeling of “metal houses” and become the first choice for high-end homestays and passive energy-saving residences, safeguarding the peace of one room on rainy nights.
● Coastal and high-altitude extreme climate zones
Whether it is the seaside corroded by salt spray or the plateau with strong ultraviolet radiation and huge temperature difference, double-layer trapezoidal tiles provide a longer service life and safety guarantee than single-layer tiles due to their diverse material selection and structural redundancy.

Core features: hardcore technology, dimensionality reduction strike
1. Double layered hollow structure, with a geometric leap in performance
The unique hollow interlayer of the finished product is like putting a “constant temperature protective suit” on the building. Compared with the single-layer tile, the sound insulation effect is improved by more than 50%, and the thermal conductivity coefficient is significantly reduced, which eliminates the noise caused by rainstorm strikes, effectively prevents the problem of dew and water dripping caused by the temperature difference in the morning and evening, and creates a quiet, dry indoor environment for users.
2. Super strong load-bearing capacity, crush resistant wind resistance
Through the implicit reinforcement principle of “I” – shaped or box shaped in mechanics, the cross-sectional modulus of double-layer trapezoidal tiles far exceeds that of single-layer tiles. This means that at the same thickness, it can withstand greater snow pressure and negative wind pressure, easily cope with strong typhoons and extremely cold blizzard weather, and perform particularly well in large-span buildings such as airports and large factories.
3. One machine dual-mode, flexible intelligent production
The equipment adopts an independently adjustable roller press unit, which can quickly switch to produce trapezoidal tiles of different specifications (such as wave height and wave spacing). Whether it is the combination of different materials for the upper and lower layers, or the special process of adding anti condensation adhesive layers, it can be accurately achieved. The PLC intelligent control system supports remote operation and maintenance, real-time monitoring of production, error, and energy consumption.
4. High precision cold bending, zero defects in the cross-section
The mold adopts Cr12MoV quenching and precision grinding to ensure that the double-layer plate maintains micrometer level synchronous accuracy during high-speed composite, completely solving the industry problems of double-layer plate misalignment, scratching or wrinkling. The cutting system adopts hydraulic flying shears or fixed length saws for cutting, with smooth and burr free cuts that perfectly fit the waterproof edge treatment of the rear.
Win win of efficiency and quality：
Choosing a double-layer trapezoidal roof tile forming machine is not only purchasing a machine, but also choosing a forward-looking architectural concept. It uses the ultimate precision of cold bending technology to transform ordinary steel coils into a new type of building material that integrates strength, sound insulation, and energy saving.
