840 Trapezoidal & 800 Glazed Tile Double Layer Roofing Sheet Roll Forming Machine

Manufacturer: Hebei Xinnuo Roll Forming Machinery Co., Ltd. | Core Keyword: Double Layer Roofing Sheet Roll Forming Machine Manufacturer

As a professional Double Layer Roofing Sheet Roll Forming Machine Manufacturer, Hebei Xinnuo Roll Forming Machinery Co., Ltd. independently develops this dual-profile forming equipment integrating 840 trapezoidal roof panel and 800 glazed tile production. One machine produces both 800 trapezoidal roofing sheets and glazed tile roofing sheets, saving production space, investment cost and maintenance expenses. This dual-layer machine is widely favored by metal roofing factories, villa construction suppliers and prefab building manufacturers across Southeast Asia, Africa and South America.

The machine adopts double-layer separated feeding platform design. The upper layer feeds coils for 800 glazed tiles, while the lower layer loads raw materials for 840 trapezoidal sheets. The reinforced steel feeding rack supports color steel, galvanized steel and aluminum coils within 0.3–0.8mm thickness. Adjustable guide baffles prevent sheet deviation during high-speed feeding, greatly reducing material waste and improving overall production continuity.

All forming rollers are forged from GCr15 bearing steel with overall quenching and mirror polishing. The surface hardness reaches HRC58-62, ensuring clear sheet textures, scratch-free panel surfaces and long service life. Two groups of independent roller rows are arranged up and down, realizing separate molding of two different roof profiles without replacing molds frequently. The transmission system uses solid gear boxes for stable running, low vibration and low noise during long-hour continuous work.

The independent PLC touch screen control console integrates all speed adjustment, length setting and automatic cutting functions. Operators can switch between glazed tile and trapezoidal sheet production mode with one click. Equipped with overload, emergency stop and fault alarm functions, the control system minimizes operation risks for new workers. Frequency conversion speed regulation allows flexible adjustment of production speed according to order quantity, matching the capacity of uncoiler and stacking machine perfectly.

The hydraulic cutting shear is installed at the machine outlet for fixed-length automatic cutting. The shear blade adopts high-strength alloy steel, featuring sharp cutting edge and no burr on finished sheets. Each profile has an independent cutting group, avoiding cross interference during switching production modes. The hydraulic station runs stably with low oil leakage rate, lowering daily maintenance workload for factory operators.

Hebei Xinnuo’s double layer roofing forming machine features an integrated thickened steel frame welded with stress relief treatment, which effectively resists deformation under long-term heavy load. Compared with buying two separate single-layer machines, this dual-profile equipment cuts half of factory floor occupation and reduces extra purchasing and maintenance costs. We support customized forming width, working voltage and mold patterns to fit local construction standards. All equipment undergoes 72-hour continuous running test before delivery, with complete export documents and lifelong remote technical support for global clients. This dual-purpose roll former is the most cost-effective choice for medium and small roofing material manufacturers with diversified product demands.
