Introduction: Why PVC Corrugated Roofing Sheets Are Widely Used

PVC corrugated roof tiles have become a mainstream roofing material in industrial buildings, warehouses, agricultural facilities, factories, and temporary construction projects.

Compared with traditional metal sheets and fiber cement tiles, PVC roofing sheets offer:

• Excellent corrosion resistance

• Lightweight structure

• Long service life

• Low maintenance cost

• Easy installation

Behind this growing demand stands the PVC Corrugated Roof Tile Extrusion Line, a complete automated production system designed for continuous high-efficiency sheet manufacturing.

What Is a PVC Corrugated Roof Tile Extrusion Line?

A PVC Corrugated Roof Tile Extrusion Line is an integrated extrusion production line that converts PVC powder and additives into finished corrugated roofing sheets through heating, extrusion forming, cooling shaping, and cutting processes.

This production line is specifically engineered to manufacture:

• PVC trapezoidal roof sheets

• Corrugated wave roof panels

• Industrial roofing boards

• Agricultural roofing tiles

It combines extrusion technology, precision forming molds, and automatic control systems to ensure stable output quality.

Main Components of PVC Corrugated Roof Tile Production Line

A standard PVC corrugated roof tile extrusion line consists of the following core units:

Conical Twin Screw Extruder

The extrusion system usually adopts a conical twin screw extruder, which is ideal for PVC powder processing.

Its advantages include:

• Stable plasticization

• Uniform melt temperature

• High output efficiency

• Low material degradation

Sheet Die and Corrugated Forming Mold

The extrusion die shapes molten PVC into flat sheet form, which then enters corrugated forming molds to create precise wave profiles and surface patterns.

Customized mold designs allow production of:

• Different wave shapes

• Sheet thickness variations

• Customized width specifications

Vacuum Calibration and Cooling System

The vacuum forming table ensures accurate sheet dimensions and smooth surface finish. Water cooling stabilizes sheet geometry and prevents deformation.

Haul-Off Unit

The haul-off machine continuously pulls the formed sheet at synchronized speed, maintaining consistent production flow.

Automatic Cutting System

Length cutting machines ensure precise panel dimensions and smooth edges suitable for packaging and installation.

Working Process of PVC Corrugated Roof Tile Extrusion Line

The complete production workflow includes:

1. Raw material feeding and automatic dosing

2. PVC melting and plasticizing inside extruder

3. Sheet extrusion through precision die

4. Corrugated shaping and vacuum calibration

5. Cooling and dimensional stabilization

6. Haul-off traction

7. Length cutting and stacking

This continuous production process allows 24-hour industrial operation with stable output.

Applications of PVC Corrugated Roof Sheets

PVC corrugated roofing sheets produced by extrusion lines are widely applied in:

Industrial Buildings

Used in factories, warehouses, and logistics centers for lightweight roofing systems.

Agricultural Facilities

Commonly installed in greenhouses, livestock farms, poultry houses, and storage barns due to chemical resistance and moisture protection.

Coastal and Chemical Environments

PVC roof sheets resist salt corrosion and chemical vapors, making them suitable for coastal regions and chemical plants.

Temporary and Modular Construction

Used in prefabricated buildings, mobile houses, and temporary shelters.
