Roofing Tile Roll Forming Machine

Roofing tile roll forming machines are essential equipment for manufacturing metal roofing tiles and panels. This guide provides a comprehensive overview of roofing tile roll formers covering how they work, types, key components, specifications, applications, installation, operation, maintenance, suppliers, costs, pros and cons, and more.

Overview of Roofing Tile Roll Forming Machines

Roofing tile roll forming machines, also known as roof panel roll forming machines, are used to convert flat metal sheets into roofing tile profiles and panels. The roll forming process involves gradually bending and shaping the sheet metal through a series of rollers until the desired roofing profile is formed.

Roll formed metal roofing tiles are lightweight, durable, corrosion resistant, fireproof, and cost-effective. They are an economical alternative to traditional clay or concrete roofing tiles. The raw material for roofing tile roll forming is typically galvanized steel, zinc-aluminum coated steel, aluminum, or copper. The most common profiles produced are interlocking tiles, corrugated tiles, and standing seam panels.

Roll formed roofing provides excellent protection from weather elements while reducing roof weight load. Other benefits include quick and easy installation, long service life, and low maintenance. Roofing contractors, building material suppliers, metal building manufacturers, and panel integrators use these machines widely.

How Does a Roof Tile Roll Forming Machine Work?

A roofing tile roll former works by feeding a coil of flat sheet metal through a series of roller stations. Each roller station incrementally forms the sheet into the desired roof tile profile through a bending and folding operation.

The sheet metal is passed through the roller sets at a constant speed and gets gradually shaped from its original flat form into the final roofing product shape. The number of roller stations required depends on the complexity of the profile. Simple profiles like corrugated sheets may require 10-12 stations while complex profiles need 16-20 stations.

The rollers are precision machined to accurately shape the metal without defects. They bend and mold the material through a progressive series of small steps which avoids overstressing the material. The key components of a roll former include an uncoiler, feed table, forming rollers, cutting unit, and exit table. The formed tiles can be collected for further processing or directly packed for shipment.

कुंडल वजनMax 25 tons
Coil ID400-650 mm
  • Forming speed determines output and typically ranges from 50-120 m/min depending on complexity of profile.
  • Forming width is the effective working width and determines sheet width capacity. Common sizes are 1000, 1250, 1500, 2000, and 2500 mm.
  • Thickness capacity ranges from 0.15 to 1.2 mm. Thicker materials may require bigger machines.
  • Power consumption depends on speed and profiles. Larger units may require up to 80 kW.
  • Rollers are made of steel or alloy steel hardened up to 65 HRC. Flower pattern rolls improve formability.
  • Number of roll stations should match profile complexity. More stations allow more gradual bending.
  • Raw material can be galvanized steel, aluminum, or copper. Material properties impact quality.
  • Coil weight determines how often new coils need to be loaded. 25 tons is common for roofing lines.
  • Inner coil diameter ranges from 400-650 mm. Bigger ID coils require de-coilers.

  • Proper foundation leveling avoids vibration issues during high-speed running.
  • Firm anchoring prevents machine movement and deformation during forming.
  • Power supply should be stabilized and regulations followed.
  • Trial runs are needed to verify quality and tune parameters before production.
  • For operation, constant monitoring of speed, feeds, and guides alignment is required.
  • Daily cleaning and oiling maintains smooth operation and prevents corrosion.
  • Periodic roller surface inspection for wear and regrinding to keep tolerance.
  • Realigning rollers periodically compensates for deflections under load.
  • Bearing, gearbox, and hydraulics require scheduled lubrication and servicing.
  • Electrical components and wiring need to be checked for heating or damage.
