Product Description:

Hot-dip Zinc Coating Steel Building Roof Walls

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:

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Excellent anticorrosive property

Q:How much will be burned out if the soaked and oxidized 5182 aluminum coil is melt down and reprocessed?
Burn out rate is generally between 1% -2.5%, but that varies among plants as their actual situations are different.
Q:What are the production processes of aluminum coil and what are the functions of various industrial furnaces in the production of aluminum? The more detailed, the better. Thank you! Points!
General steps are as follows: melting - hot rolling - cold rolling - annealing – shearing – straightening – punching
Q:Why does the coated aluminum coil have thickness requirement for membrane?
The purpose of coating is to protect the surface of aluminum coil and make it more aesthetic. The thickness of membrane is closely related to the keep years of products made by aluminum coil.
Q:Why does fillet appear when rolling aluminum coil?
How thick and wide is it when there is such problem? Which is the rolling pass? And what is the type of the rolling mill? The simple 4 rollers or CVC and HC rolling mill with roller control. Does the filler appear in rolling or out of roller? Different thickness will lead to different analysis.
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:What is the common color of aluminum coil membrane?
The blue transparent membrane is the most common.
Q:How to measure the thickness of aluminum coil at real time? In what areas can the sensor be used?
I suggest that you use the laser displacement sensor for real-time measurement of the thickness of aluminum coil. ZLDS100 can exactly measure the change value of aluminum coil thickness through simple technique in the thickness measurement project, which can help judge the production phase and status.
Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
It is either the external or the bearing problem in designing and installing.
Q:What is color aluminum coil?
Colored aluminum coil is that the aluminum alloy whose surface has been shaded. The surface color after special treatment will not fade within 30 years at least because of the stable performance and good corrosion resistance. The weight per unit volume of color aluminum coil is the lightest among metal materials because of the low density and high hardness. Color aluminum is a newly emerging material in the field of doors and windows. Compared with steel, the biggest advantage is unparalleled firmness, varied colors and non-toxic for which steel has always been blamed. Therefore, it is widely used in areas such as doors and windows, sunroom and balcony seal. Color coated aluminum coil has become one of the most popular decorative material which is environmentally-friendly, durable and aesthetic. As a decorative material, it has the following unparalleled advantages: uniform color, bright and clean, strong adhesion, durability, anti-acid and anti-alkali, corrosion resistance, wind and weather resistance, decay and abrasion resistance and ultraviolet proof. Products categories: polyester coated aluminum coil (PE) and perfluorocarbon coated aluminum coil (PVDF).
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
