Roofing sheets or corrugated steel roofs are commonly used in construction projects for the purpose of shading from the sun, wind, etc. There are many different types of corrugated steel sheets on the market, based on the purpose of use, cost, etc. durability that customers can choose.
Corrugated steel sheet
Corrugated steel sheets are steel sheets that are thinly rolled and undergo galvanizing or zinc-aluminum plating, and then square or round corrugated (corrugated) with high aesthetics.
Currently, corrugated iron is mainly used for roofing and partitions for civil and industrial buildings.
Corrugated steel is divided into 3 main types: industrial corrugated steel (5-wave corrugated iron, 7-wave corrugated iron) and civil corrugated steel (9-wave corrugated iron, 11-wave corrugated iron), and 13-wave corrugated steel. Depending on the needs and preferences, users can learn and choose the appropriate type of corrugated steel sheets.
Galvanized steel sheet in coil
Galvanized steel sheet (also known as zinc corrugated steel) is a kind of building material made from metal sheets (steel plates) and the surface is covered with a layer of zinc during the hot dipping process.
With the advantage of zinc corrugated steel is light, easy to transport, high strength and good rust resistance. Therefore, this type of material is easily encountered in daily life such as household electrical appliances. Has high applicability in the construction industry, used to manufacture roofing sheets, fabricating partitions and gutters, etc.
Color coated steel or Pre-painted Galvanized
This is a type of thin-rolled steel that has undergone the process of galvanizing aluminum-zinc alloy with the usual proportions of 55% Aluminum, 43.5% Zinc and 1.5% Silicon.
The aluminum component in the plating creates a mechanical barrier against environmental influences in different climatic conditions.
The zinc component in the plating provides sacrificial electrochemical protection to the base metal. When exposed to water, moisture, zinc will create a protective compound at the cutting edges or scratches.
