Metal roofs are a top – choice for many because of their elegant appearance, high durability, long lifespan, energy – saving properties, and low maintenance requirements. They can significantly enhance the aesthetic appeal of a building, making it look its best.
There is a wide range of materials available for metal roofs, including zinc, tin, galvanized steel, aluminum, copper, and others. The manufacturing process of metal roofs is not one – size – fits – all; it is influenced by factors like the material used, the design of the metal roof sheets, and more.
The standard process of the roofing sheet manufacturing
Material
The first step is to turn raw materials like galvalume, aluminum, zinc, copper, and stainless steel into the desired form. They’re purified and melted into metal coils. In Chennai, metal roofing uses a special raw – material mix for better environmental resistance. Then, the coils go through a rolling machine to reduce thickness and reach the required grade, which varies by raw material.
Coating
The coil enters the coil coater where a Kynar 500 or Hylar 5000 coating system is applied. It moves along a continuous coating line, gets cleaned, painted, and baked at high – temperature. Quality is checked after each paint coating. Quality assurance engineers also conduct redundant checks before the manufacturing process.
Roll forming mill
The third step is to feed the metal coil into the roller former. This machine is crucial for transforming the coil into metal sheets and panels. Its main functions are to reduce the coil’s thickness and reach the desired grade. Successive rolls of the roller give the material its shape and bends. The sheet width is manually adjusted according to the design.
The metal coil for roller – forming seams passes through a roll – former system. A roller former turns the metal coil into roofing sheets and panels, playing a key role in shaping the roof sheet designs. It can be adjusted to create the desired panel designs. The seam panel is made by feeding the metal coil into the roll former to get the right curves and profiles. Successive rolls effectively bend and shape the metal. The panel width, usually 12″, 16″ or 20″, is manually set in the roll – forming machine according to the roof seam design. An extra 4″ is left to form locks on both sides of the panel.
PLC control system
Most metal roofing sheet manufacturers use a computer control unit to adjust speed, operation, panel length, etc. This unit simplifies the adjustment of the roll – forming machine according to needs. It automates the manufacturing process, feeding the coil as required and cutting panels to a specific length.
Sheet metal
In addition to metal panels, metal roof manufacturing involves numerous other elements, including small accessories like rakes, gable trims, drip edges, ridge caps, sidewalls, and roof – to – wall connections. All these elements are produced through a detailed process to ensure the panels perform optimally.
Quality Check
The product is promptly inspected for color, appearance, and quality. After the sheets pass the quality check, they are carefully packed for transportation and are then ready for a lifetime of installation on your roof.
Metal roof manufacturing encompasses multiple processes and steps. It’s crucial to pay close attention to each process to ensure the final product meets the highest quality standards. Most manufacturers follow a standard process to produce metal roof sheets, panels, and designs.
Metal roofs are highly favored for their high endurance and long lifespan. They are sturdy and can withstand various climatic conditions, keeping your property warm and dry. Metal roofs offer excellent protection for your house and have high resistance. They are a trusted roofing solution for those seeking durable options.
