High Speed Commercial Metal Roof Tile and Panel Roll Forming Machine 0-20 m per minute

20 Station Tiles Making Machine Metal Roof Delivers Reliable Roll Forming

What do you worry about most when buying a metal roof tile machine? That the frame shakes at high speed and panel dimensions drift? That the rollers wear out and lose precision after two years? That the shafts bend and require a major repair?

These problems all trace back to the main roll forming system. It is the heart of the entire production line. It determines how many years you can run stably, how low your scrap rate stays, and how much you spend on maintenance. This article starts with the main roll former, explains its structure, configuration, durability, and complete line options, and helps you decide if this tiles making machine metal roof fits your production needs.

Machine Overview

This tiles making machine metal roof processes steel coils into finished metal roof tiles continuously. The complete line covers five stages: uncoiling, feeding, roll forming, cutting, and collecting. The coil enters from the decoiler, passes through the entry table into the main roll former, gets cut to length after forming, and is collected by the receiving tables. Let us look at this equipment from two angles: its advantages and its applications.

Machine Advantages

• Double chain drive provides reliable power transmission

• PLC control with touchscreen runs automatically after parameter setup

• Hydraulic cutting with encoder measurement delivers accurate length cutting

• Touchscreen supports multiple languages for easier operation

• Optional automatic decoiler and automatic stacker adapt to different capacity needs

Applications of Metal Roof Tiles

• Roof covering for industrial plants and warehouses

• Sloped roofing for residential housing

• Simple roof structures for agricultural greenhouses

• Metal roofing systems for large public buildings

• Exterior wall cladding for commercial buildings

Different applications have different requirements for profile type, material thickness, and surface quality. But stable forming accuracy is the common foundation for all of them.

Why the Main Roll Forming System Is the Core of the Line

Now that you understand the complete machine, let us focus on its most important part: the main roll forming system. The profile, dimensional accuracy, and surface quality of metal roof tiles are determined at this stage.

A main roll former consists of the frame, rollers, shafts, drive system, and control system. The steel strip enters from the feeding side, passes through each roller station one by one, deforms gradually, and exits as a complete profile. This process runs continuously at up to 20 meters per minute. If the main roll former has a problem, the whole line stops.

The core features of the main roll forming system on this tiles making machine metal roof are:

• Gradual forming with 20 stations, each bends a little, so hard materials resist cracking

• 45# steel rollers with hard chrome plating for smoothness and wear resistance

• 400 H beam steel welded frame, weighing 6.5 tons, for stability at high speed

• 45# steel quench treated shafts, 80mm diameter, for long term load resistance

Durability Design of the Main Roll Former

We have covered what the main roll former does. Now let us look at why it can do it consistently over many years.

The durability of the main roll former comes from three parts: the frame, the rollers, and the shafts.

The frame uses 400 H beam steel welded construction. A welded structure maintains stability under long term high speed operation. The roller surface has hard chrome plating for wear resistance. The shafts are quench treated and measure 80mm in diameter, so they resist bending under continuous load.

Stable forming directly affects finished product quality. A rigid frame keeps the rollers from shifting at high speed, so every sheet stays consistent in shape.

Long Term Operation Maintenance Points

No matter how robust the structural design is, proper daily maintenance is necessary to get the most out of its durability. Maintaining the main roll former is not complicated. Three things need daily attention:

Roller surface: Check for wear or foreign object scratches. The hard chrome plating resists wear well.

Chain tension: The drive uses double chains. Check tension regularly.

Lubrication: The shafts and chains need regular lubrication. We recommend checking every shift and doing a full maintenance check every month.

Regular inspection helps avoid unexpected breakdowns. The rigid frame and quench treated shafts of the main roll former ensure long term stability.

Complete Line Main Parameters

Complete Line Configuration and Selection Guide

The parameters above show the core data of the main roll former, but a complete production line includes other supporting components:

• Decoiler: 2 manual decoilers as standard, can be used alternately; optional hydraulic automatic decoiler available

• Entry table: includes manual pre shearing device, cuts only the joint section during coil change

• Cutting mechanism: hydraulic driven, PLC controlled length cutting

• Receiving tables: 2 as standard; optional automatic stacker available

If you have high coil change frequency, consider the automatic decoiler. If you have high output, consider the automatic stacker.

The durability of the main roll former comes down to three factors: the rigidity of the welded frame, the wear resistance of the chrome plated rollers, and the bending resistance of the quench treated shafts.
