Product Description:

Hot-dip Zinc Coating Steel Building Roof Walls With 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:Cold rolled steel coil steel, what is the difference?
From the last finishing mill stand out of the hot strip laminar cooling through to the set temperature, the coiling machine rolled strip steel roll cooled, according to the different needs of users with different finishing line (flat, straightening, transverse or longitudinal, inspection, weighing, packing and marking etc.) processing and become steel, flat steel product volume and slitting, its strength is not very high, but the ductility and weldability is good, the appearance of color is not bright, easy to corrosion, because the price is cheap, the majority of enterprises in order to reduce the cost, so the more commonly used.
Q:What does "steel roll number" mean?
The coil numbers in the steel industry are generally applicable to rolled round steel bars. A coil of steel has a specified length and weight. Different rolls have different volumes
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
Q:How can the outer diameter and weight of steel coil be converted?
When it comes to this question, in fact, a lot of them are irrelevant. The weight of the steel rolls means that there is a unit weight called the weight of each mm in the width of the steel coil
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 maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
The length of the roll is related to its width and thickness, but not to the extent of the zinc layer.
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:How to solve steel plate storage
According to the principle of "first in first out" to carry out the turnover, organize the logistics, reduce the large amount of moving plate, reasonable arrangement, easy to steel coil into the use of state.
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
Steel plate is divided into many kinds of PU, low alloy, boiler plate, vessel plate, high strength plate, etc..
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
