Hot-dip Zinc Coating Steel Building Roof Walls With Best Price Best Quality

1.Structure of Hot-Dip Galvanized Steel Sheet Description

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.

2.Main Features of the Hot-Dip Galvanized Steel Sheet

Q:What's the best material for color coated steel coil?
The base material of color coated coil is mainly galvanized steel or galvanized alloy steel plate.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:How can the outer diameter and weight of steel coil be converted?
To obtain the outer diameter of the steel coil is calculated according to the density of 7850, according to the density, in general, hot-rolled is 0. 96~0, 98, cold rolled, according to 0. 98~0. Ninety-nine
Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
Steel is usually stable in performance. One thing is that the environment should be dry, not rain, because the damp environment is easy to rust. As long as it's in a dry room, it's basically no problem.
Q:Several reading methods of steel tape measure
Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:What is the material of steel coil 08F and what brand can be used instead?
20 steel used for various mechanical parts is not subjected to great stress and toughness, such as rod, sleeve, screw, lifting hook; also can be used for manufacturing in 60 pressure and 450 DEG C using non corrosive medium pipes, pipe; can also be used for carbon and cyanide carburized core strength is not the chain, such as bushings, roller, shaft and gear, sprocket and other important.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
The difference between hot rolled primary and hot-rolled carbon thin steel coils is that they include carbon steel rolls and low alloy steel coils.
Q:What is the difference between cold rolled strip and cold rolled steel coil?
Single literal explanation, volume and band are different, appearance shape is not the same.
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
