Product Description

China manufacture galvanized steel roofing sheet corten steel roof sheet price

A galvanized sheet is a steel sheet whose surface is coated with a layer of zinc. Galvanizing is a cost-effective and effective rust-preventing method that is used in the world for about half of the world's zinc production.

Category

According to production and processing methods can be divided into the following categories: 1 hot dip galvanized steel sheet. Immerse the steel sheet in the molten zinc tank A thin steel plate with a zinc layer attached to its surface. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a plating tank in which zinc is melted to form a galvanized steel sheet; 2 alloyed galvanized steel sheet. This steel sheet is also produced by hot dip, but immediately after it is discharged, it is heated to about 500 ° C to form an alloy film of zinc and iron. This galvanized sheet has good adhesion and weldability of the coating; 3 electro-galvanized steel plate. The production of such a galvanized steel sheet by electroplating has good processability. However, the coating is thinner and the corrosion resistance is not as good as that of hot dip galvanized sheet; 4 single-sided plating and double-sided differential galvanized steel. Single-sided galvanized steel, that is, a product that is only galvanized on one side. It has better adaptability than double-sided galvanized sheet in welding, painting, anti-rust treatment and processing. In order to overcome the shortcomings of uncoated zinc on one side, there is a galvanized sheet coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized sheet; 5 alloy, composite galvanized steel sheet. It is made of zinc and other metals such as aluminum, lead, zinc, etc., or even composite plated steel. This steel plate has excellent rust resistance and good coating properties; In addition to the above five types, there are also colored galvanized steel sheets, printed galvanized steel sheets, and polyvinyl chloride laminated galvanized steel sheets. However, the most commonly used ones are still hot dip galvanized sheets.

Physical properties

Tensile test: 1 Performance indicators: Generally speaking, only galvanized sheets for structural, tensile and deep drawing have tensile properties. Among them, galvanized sheets are required to have yield point, tensile strength and elongation, and elongation is required only for elongation. For specific values, see the relevant product standards in “8” of this section; 2 Test method: Same as the general thin steel plate test method, see the relevant standards provided in “8” and the test method standards listed in “Ordinary Carbon Steel Sheet”. (2) Bending test: The bending test is the main item to measure the performance of the sheet. However, the requirements of various standards for various galvanized sheets are not consistent. The US standard does not require bending and tensile tests except for the structural level. In Japan, except for structural grades, building corrugated sheets and general corrugated sheets, bending tests are required. Requirements: Generally, after the galvanized sheet is bent 180, the outer surface shall not have a zinc layer to be detached, and the plate base shall not be cracked or broken.

chemical composition

.The requirements for the chemical composition of the galvanized sheet substrate are different in national standards. The national standard generally measures the content of carbon, manganese, phosphorus, sulfur and silicon.

Packing & Delivery

galvanized steel sheet

It is divided into galvanized sheet cut into fixed length and packaged in galvanized sheet. Generally, the metal packaging is lined with moisture-proof paper, and the iron waist is bundled on the bracket. The strapping should be secure to prevent the inner galvanized sheets from rubbing against each other.
