Installation precautions for galvalume corrugated roofing sheets

No matter what product is produced and applied, the reason why it can be further developed is that it has certain excellent characteristics, and it can also explain that the use of the product can play some role, which is what we expected. The effect is the same for the application of low cost Galvalume Corrugated Roofing Sheet, but in order to make it work smoothly, there are also many problems to be aware of during its use, such as galvalume corrugated roofing sheets.

1. We should meet the shelving length of the lintel in our construction and ensure that the adhesive at the support surface is even and full.

2. The control joint should be set according to the design requirements. The flexible material such as foaming agent embedded in the joint can adapt to the deformation requirements of the wallboard.

3, regardless of drilling or slotting are damaged by a single aluminum-zinc roofing panel, therefore. After the galvalume corrugated roofing sheet is assembled and reached the overall strength, it can be drilled and slotted. In order to better bond, the bonding surface of the partition wall board should be cleaned, and the binder should have good water retention performance, so the board should not be watered before bonding.

Common Type Of Cold Rolled Coil

The high quality cold rolled steel coil china: cold-rolled from ordinary carbon structural steel or low-alloy structural steel into cold-rolled sheet with good surface quality and good punching performance. It is required to enise that the cold bend and cup test are qualified for the raw materials of the automotive industry and the coated board.

Cold-rolled high-quality steel coil: mainly including various high-quality steel cold-rolled coils, the most commonly used carbon-structured steel sheets, especially cold-rolled steel sheets for deep-drawing are made of low-carbon high-quality steel 08Al cold-rolled coil steel according to surface quality. The three groups I, II, and III respectively indicate that the special advanced, advanced, and high finishing surfaces are classified into ZF, HF, and F grades according to the drawing level. According to the allowable deviation of the thickness of the steel plate, it is further divided into two grades A and B, which are widely used in the automobile tractor industry.

Cold-rolled steel coil: Excellent surface finish for household appliances such as automobiles, refrigerators, washing machines, industrial equipment, and various building materials. With the economic development, cold-rolled steel coils have been called essential materials for modern society.

Roofing Sheet's Three-Step Approach To Problem Solving

The skeleton of the high quality Galvalume Corrugated Roofing Sheet, that is, the curve, is a combination of several more complicated curves. It affects the tightness of the seal installation and whether the roof shape can reflect the architectural design requirements. The solution to this is:
1. Accurate calculation of the wing sample for the rubbing, supplementing several simple parts that can be adapted to various angles and position adjustments.
2. When installing, use the baseline reference line to adjust the deflection change caused by the deformation of the steel structure.
3. The sealing baffle itself is assembled with narrow strips to accommodate the shape of the non-expandable curved surface.
Paying more attention to the above two problems in detail can reduce many problems caused by improper handling. Roofing manufacturers can take care of these problems during installation, which can make consumers trust manufacturers and choose more products.

Cold Rolled Steel Coil

Cold rolled steel coil factory supplier tells you what a cold rolled sheet is.
The production of cold rolled strip requires not only high precision of surface and dimension, straight shape of a strip but also good structure and properties. The cold rolled strip has the following characteristics in a rolling process:
Because cold rolling takes place below the recrystallization temperature of metals, the strength and hardness of metals increase while the plasticity decreases during cold rolling. This phenomenon is called work hardening. The result of work hardening is that the deformation resistance increases, the rolling pressure increases, the plasticity decreases, and brittle cracks easily occur. After work hardening exceeds a certain degree, the rolled piece will be too hard and brittle to continue cold rolling. Therefore, after a certain pass of cold rolling, the steel plate is often softened (recrystallization annealing, solution treatment, etc.) to make the rolled piece plastic, reduce the deformation resistance, so as to continue rolling thin.

Suggestions On Fire Protection of Coloured Steel Sheet

PPGI corrugated roofing sheet for sale is used more and more in the society nowadays. Both material structure and construction technology have been improved to a certain extent. At the same time, the safety and fire prevention measures concerned by people are beginning to diversify. In the past, some methods have been adopted, such as setting fire barrier with cast-in-situ solid concrete outer layer, setting fire-resistant brick, covering with gypsum board or adopting external water-filled cooling of hollow pipe.
Now all the people who use PPGI corrugated roof panels know that fire prevention is the biggest problem. The news about the fire of colored steel plate is endless. In fact, the most fundamental problem is not the quality of products, but the appropriateness of the selected products and the standardization of the use, which is very important. Following are some suggestions on fire protection of PPGI corrugated roof panels from China color corrugated steel sheet manufacturers.
1. PPGI corrugated roof panel products are progressing continuously. If you want to completely prevent fire and use safely, you have to choose color steel plate with good fire resistance, such as rock wool color steel plate, which is almost non-flammable. This product has been widely used, and used customers have said well.
2. in the process of using color steel products, we must keep away from fire sources. If the selected color steel plates are ordinary foam color steel plates, it is best not to set up kitchens in the color steel plate room, so far away from the fire source will naturally bring no fire.
3. In PPGI corrugated roof panel, do not use excessive power and illegal electrical appliances, so as to avoid fire caused by leakage of electricity, wire and cable is best not to pass through the core material of color steel plate.
4. Fire extinguishing equipment such as fire extinguishers must be provided in the color steel plate movable room, which is convenient to extinguish in time when a fire breaks out. If conditions are good, fire alarms can be installed to facilitate the personnel inside to escape the fire quickly and avoid casualties.
5. PPGI corrugated roof panels must be kept at least 6 meters apart, which is also very important. Normally responsible manufacturers will pay attention to this point. Users should not dismantle the color steel plate privately, and must inform the professionals of China color corrugated steel sheet manufacturers.
The use of color steel products as long as these points of attention, can reduce the possibility of fire, must not ignore some details, fire is likely to be caused by details, I believe that we pay attention to these issues, the use of color steel products, will be very safe, will not lead to fire. With the continuous progress of science and technology, under various new materials, the fire protection measures of color steel house have changed further. At the same time, according to what we know now, more and more people adopt the layout of spraying fire-proof coating and anti-corrosion coating to protect steel.
