If you have seen the wave-shaped iron sheet roofs of factory buildings or rural self-built houses, that is the material we are going to talk about today - Corrugated Galvanized Sheet Metal. This material may seem simple, but the underlying process and supply chain actually have quite a few nuances.
How was it made?
In simple terms, the processing of Galvanised Corrugated Roofing Sheets involves two steps. The first step is to subject hot-rolled or cold-rolled steel coils to hot-dip galvanizing, which forms a zinc layer on the surface to prevent rust. The second step is to place these galvanized sheets in a rolling forming machine and use a series of rollers to press the flat sheets into a wavy shape. The entire process is continuous cold bending, without heating, relying on mechanical force.
The Galvanized Roofing Sheets produced in this way have both the corrosion-resistant protection of the zinc coating and the strength brought by the corrugated structure. The higher the waves and the closer the spacing, the stronger the bending resistance of the sheet will be.
Where is it suitable to be used?
This kind of corrugated board is very common on construction sites. It can be found in industrial buildings, residential houses, warehouses, sports venues, airport terminals, large-span steel structure houses - basically, it can be used for any decoration on the roof, exterior walls, or interior and exterior walls. It is lightweight, fast to install, and doesn't rust even on rainy days.
Why can we trust the materials of ZZ Group?
The ZZ Group was established in Yangpu District, Shanghai in the early 1980s. It started out by engaging in steel trading, and later gradually expanded into processing and distribution, raw materials, real estate and financial investment. Its registered capital is 200 million yuan. The key point is that they have their own processing factories and also cooperate with several long-term partner galvanizing and profiled production lines. From the steel coils entering the factory to the profiled sheets leaving the factory, the Corrugated Galvanized Sheet Metal of each batch has records of thickness, uniformity of the galvanizing layer, and wave size. It is not something randomly produced by small workshops.
To sum up
If you are looking for a batch of stable-quality Galvanised Corrugated Roofing Sheets, whether for industrial projects or civil buildings, the supply chain system of ZZ Group can help you avoid many troubles in the middle links. The color, thickness, wave shape, and fixed-length can all be customized according to the project requirements. OEM customization is also available.
