The three-layer color steel forming machine is a cold bending forming equipment that integrates three different tile types. The mainstream configuration includes upper layer 850/828 glazed tiles, middle layer 900 wall panels, and lower layer 840 roof panels. One set of equipment replaces three single machines, saving land occupation, investment, and fast changeover. It is suitable for 1000-1250mm color coated/galvanized coils and is widely used in steel structure factories, villa roofs, fences, new rural transformation projects, etc.

Equipment structure composition

Uncoiler: 

• Passive/Hydraulic Uncoiler, capable of carrying 5-8 tons of coil material, preventing deviation and ensuring smooth feeding.

Feed import platform:

• Three layer independent guiding and correction to ensure that the board enters the forming area of each layer in a straight line.

Three layer molding host：

• Lower layer: 11 rows of rollers pressing 840 roof panels (wave height 25mm, effective width 840mm);
• Middle layer: 9-row rolling mill pressing 900 wall panels (flat arc type, effective width 900mm);
• Upper layer: 9-row roller press 850/828 antique glazed tiles (wave height 25mm, effective width 850/828mm);
• Three layer independent transmission, one key switching, and non-interference with each other.

Hydraulic shearing system: 

• rear cutting design, three-layer independent cutting, smooth and burr free cutting, precise length.

PLC control system:

•  Delta PLC+touch screen, parameter storage, fault alarm, 15 minute quick changeover, single person operation.

Discharge rack:

•  A 4-6 meter three-layer material rack that is scratch resistant and convenient for collecting finished products.

Core advantages

1. One machine, three types, the king of cost-effectiveness

• Simultaneously producing 840 roofs, 900 walls, and 850 glazed tiles, saving 60% of land and 50% of investment, replacing three single machines.
• Changing the mold only takes 15 minutes, saving 60% of the time compared to traditional single machine models. It is suitable for flexible production of multiple orders and small batches.

2. Efficient and labor-saving, doubling production capacity

• Three layer independent drive, capable of single layer independent operation or three-level staggered production, with a daily production capacity of 2000-3000 square meters and an efficiency improvement of over 50%.
• PLC intelligent control, one click setting of length, quantity, and speed, beginner can get started in 1 hour, single person on duty.

3. Precise and durable, stable molding

• Thickened H-beam frame+solid shaft, long-term operation without shaking or deformation.
• The rolling mill is coated with hard chrome for wear resistance, with a size error of ≤ 0.5mm, consistent tile shape, seamless overlap, and a flat surface without raised edges.

4. High material utilization and low loss

• Continuous feeding+servo cut to length, reducing the scrap rate to below 1.5%, saving tens of tons of raw material costs annually.

Application scenarios

• Lower 840 roof panel: steel structure factory, warehouse, and residential roof, waterproof and durable;
• Middle layer 900 wall panel: factory walls, building exterior walls, fences, beautiful and rust proof;
• Upper layer 850/828 glazed tiles: villas, antique commercial streets, temple ancient buildings, new rural renovation roofs, antique high-end.
