ZhongTuo Launch TR4 Trapezoidal Color Steel Roof Tile Roll Forming Equipment Customizable

ZTRFM new TR4 trapezoidal color steel roof tile roll forming equipment is officially online. It focuses on lightweight metal enclosure panel production and is specially designed to manufacture TR4 trapezoidal roof sheets for domestic engineering supply and cross-border building material export business. The new product optimizes forming pass design to bend sheet metal step by step and release internal stress of steel, effectively improving common industry problems such as tile springback and uneven waves, stably producing high-standard TR4 trapezoidal roof color tiles.

The machine adapts to 1000–1250 mm width color steel coils with processing thickness from 0.3 mm to 0.8 mm, compatible with PPGI galvanized color plates and GL galvalume substrates. The whole machine production speed is 15–20 meters per minute and speed can be adjusted according to order requirements, supporting both small batch sampling and large-scale continuous production. The main rollers go through precision machining and hard chrome hardening with smooth surface. They protect color plate coatings during rolling, reduce paint scratches and improve finished product appearance, more suitable for high-quality roof tile orders for export.

The whole machine components: uncoiler bracket, feeding guide device, roll forming main host, hydraulic shearing system, PLC electric control cabinet and finished product outlet platform. The electric control system integrates touch screen, supporting customized cutting length, automatic counting and fault prompt alarm. Production data is intuitive to view and reduce manual recording errors. The hydraulic shearing unit responds quickly with smooth cuts to reduce waste and improve raw material utilization rate.

Multiple configuration options are available for this product. The basic configuration contains a manual uncoiler frame for small and medium-sized building material processing factories with limited budget; upgraded options include hydraulic automatic uncoiler, sheet deviation correction device and automatic finished product stacking table to reduce labor intensity of feeding and picking materials for large-scale factories. The machine adopts modular design. Additional accessories can be added for upgrade during capacity expansion later without replacing the whole machine to protect fixed asset investment.

TR4 trapezoidal roof color tiles produced by this machine own reasonable rib structure and excellent drainage performance. Rainwater flows down quickly along tile grooves to reduce roof leakage risks. The finished sheets feature low self-weight and lower load on building roofs, applicable for steel structure factories, logistics warehouses, roof renovation of rural residential buildings, simple garages and breeding sheds. For overseas markets, TR4 trapezoidal tile is a general roof profile with strong demand in infrastructure projects of Africa, Southeast Asia and South America, becoming a hot-selling product for foreign trade building material merchants.

The new equipment supports complete delivery services including pre-delivery material test running, on-site installation & commissioning, operation and maintenance training. The machine frame is welded with thickened H-beams with solid structure, low vibration at high speed and slow forming precision attenuation in long-term use. Daily maintenance items are simple: clean iron scraps on rollers every day, regularly add lubricating oil, check hydraulic oil level and fasten connecting bolts to reduce unexpected shutdown.

Custom tile forming is supported at purchasing stage. Customers can provide TR4 tile drawings or physical samples. The factory will make mould trial production and provide samples to verify size and appearance before whole machine production. Meanwhile, production line layout plan can be offered with reference for workshop space, floor bearing capacity and power supply power to help customers plan workshop arrangement in advance.

This new product differs from simple low-end roll forming machines on the market. It strengthens materials of three core components: spindle, roller and cutting blade to avoid problems such as bending of hollow spindle under long heavy load and rapid blade wear. The machine can be packed in containers for cross-border sea export with split fixing and good protection to reduce damage risks during ocean transportation. Chinese and English machine operation manuals are provided for overseas customer maintenance.

After putting into production, factories can independently control product specifications, colors and sheet thickness of roof tiles, flexibly respond to customized demands of engineering customers without relying on external tile suppliers. Whether supplying domestic local engineering projects or exporting large batches of building material orders overseas, this TR4 forming machine can serve as core production equipment to help enterprises expand metal roof building material business.
