Production Technology of Galvalumed Steel Plate

The surface of low cost galvalumed steel plate is characteristic of smooth, flat and rich star flowers, and the base color is silver white. The coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon. The production technology of aluminizing zinc is similar to that of the galvanizing steel plate and aluminizing plate. The 55% al - Zn alloy coating has superior corrosion resistance when both sides are exposed in the same environment. The 55% al - Zn alloy coating has not only excellent corrosion resistance but also excellent adhesion and flexibility.

The long-term corrosion resistance of metal coating products mainly depends on the melting rate of coating and coating thickness, the melting rate of galvanized steel plating is higher than that of 55% aluminum-zinc alloy coating. Therefore, the service life of 55% al - Zn alloy coating is longer than galvanized steel plate.

Galvalume steel plate is similar to the silver-white beautiful appearance of the galvanized steel plate and excellent appearance and processing, especially in the steel plate rarely appear processing part crack, the processing part durability is more excellent. In addition, the heat resistance is far better than the galvanized steel plate, thermal reflection than galvanized steel plate more than two times. Uncoated products used in the roof and partition plate can get the effect of energy saving.

Aluminum plating zinc plating layer coating adhesion is relatively good, and therefore without Weathering such as pretreatment, can also directly coated on the advertisement board and usually use plank.

Galvanized Steel Sheet Main Market

Construction and light industry is the main market of galvanized sheet, about 30% of the demand for galvanized sheet. China color corrugated steel sheet manufacturers from the speed of national economic development and the previous consumption base, its total demand in the first half of about 4 million tons, equivalent to refined zinc consumption of 180,000 tons.

From the perspective of the demand for galvanized steel in the home appliance industry, air conditioning is the main product of galvanized steel consumption. The backboard after air conditioning indoor machine and cabinet machine, interior piece, the casing of the outdoor machine, the interior wait is to make by the galvanized board, average one air conditioning consumes the galvanized board of 22 kilograms. In addition, each washing machine consumes about 8 kilograms of galvanized sheet, and each refrigerator consumes about 3 kilograms of galvanized sheet.

The automobile industry is also a major consumer galvanized sheet industry, its weight is much larger than the home appliance industry. Since 2006, the output of our country automobile increases quickly, especially with car outstanding. According to the calculation of about 350 kg of galvanized sheet per vehicle, the annual demand for galvanized sheet in China's automobile industry is at least about 3.1 million tons.

The construction industry needs a large number of colored corrugated steel plates to make ventilation pipes. For example, a medium-sized building needs more than 25,000 square meters with a total of 200 tons of each specification. Of course, this does not count the consumption of processing. At present, there are still many large engineering projects being built in China, and the demand is also very large.

What is Installation Works for Color Roofing Sheets

First, the correct placement of the color-coated corrugated roofing sheet
1. Overlapping type (applicable to the length of ≦ the 15M roof)
2. Staggered (applicable to the length of ≧ the 15M roof)

Second, the correct use of special nails
1. Special nails must be hit in the middle of China color-coated corrugated roofing sheet to have a waterproof effect.
2. The special nail fixing interval is 50CM～100CM (preferably 4/m2).
3. Special nails must be struck from the lower end of the roof sheet to the roof to highlight the beautiful, sealed and tidy effect.

Third, install the sealing strip roof sheet sealing cover
1. Separate the seals in half, and press the color-coated corrugated roofing sheet to press the roof sheet at the roof and fix it with special nails.
2. At the junction of the side roof sheets, the ridge roof sheet is directly covered with cement for sealing treatment, and the bottom of the ridge roof sheet is closed with the cabin sheet file.
3. Install the sealing cover directly at the lower end of the roof sheet, ie, the eaves and fix it with screws.
4. At the intersection of the ridge color-coated roofing sheets, the contrast interface is trimmed with scissors and then overlapped and sealed with glass glue.

Fourth, the protruding part of the waterproof treatment
First, make a V-shaped material, you can choose different materials and specifications, depending on the actual situation. After installing the water receiving a place at the bottom, place the color-coated corrugated roofing sheet on it.

Five, inclined surface connection installation
Refers to the construction of the two roofing roof sheets after the angle and length are cut off, and the bottom is installed with water treatment. First, install the water-receiving material (that is, the gutter) under the roof sheet, and then finish it with waterproof adhesive or cement.

What is PPGI Corrugated Roofing Sheet

The high quality PPGI corrugated roofing sheet is a new type of material and is the same material as the color coated steel sheet. The essence of its manufacture is to apply an organic coating on the PPGI corrugated roofing sheet.

It is usually used to build movable board houses or wall slabs that make up simple houses. It is usually used in the construction industry.

PPGI corrugated roofing sheets have many excellent properties. For example, the weight is very light, much lighter than bricks, so it is easy to transport and can save transportation costs. Moreover, it has many characteristics that other materials can't do, such as having good heat insulation and water-tightness, and high hardness. The houses built have generally had certain earthquake resistance and wind resistance, and are very practical. The installation process is also very fast and easy, and can effectively shorten the construction period, which is the best choice for cost saving.

But even though the benefits of PPGI corrugated roofing sheets are numerous, they can't be avoided with some slighter deficiencies than other materials. For example, in the manufacturing process of PPGI corrugated roofing sheets, there are many irregular operations, resulting in a certain amount of waste of social resources, but as long as it is a standardized operation manufacturer, there is no problem in production, but it is more environmentally friendly and energy-saving.

PPGI corrugated roofing sheets can be used in a wide range.

It can be used to build temporary workshops, warehouses for storage, even the top of the building, and then temporary shelters such as temporary resettlement sites for disaster victims in the disaster areas can find the use of PPGI corrugated roofing sheets.

Nowadays, social environmental awareness has gradually strengthened, and people are paying more and more attention to the importance of low carbon. PPGI corrugated roofing sheet is an extremely energy-saving material that can be recycled, arbitrarily assembled, saves materials during production, and has a lightweight, so it has been sought after by contemporary people. People prefer to use PPGI corrugated roofing sheets as construction materials.

color-coated sheet manufacturer introduces various core materials

Color-coated corrugated roofing sheet manufacturer introduce color steel plate various core material functions:

1. Color steel sheet foam board: It is made of expandable polystyrene (EPS) particles, which is like chemical fertilizer particles.
