Where Is The Wholesale Color Coated Rolls?

China high quality prepainted color galvanized coil

Among the color-coated products, China aluminum zinc steel coil and galvanized color steel plates have been highly praised by the market. Color coated rolls have also become synonymous with high-end products. So, is there a wholesale of color coated rolls in China? The answer is yes.

Shandong HENGZE New Material Co., Ltd., a provider of modern steel roofing materials in Central China, specializes in China high quality prepainted color galvanized coil and has the following three advantages:

1. Excellent molding performance, which can meet the requirements of roll stamping, bending and other forms of processing.
2. Good heat resistance. Ordinary hot-dip galvanizing products usually use a temperature not exceeding 230°C and will change color at 250°C. Baosteel’s galvanized sheet can be used for a long time at 315°C.
3. High reflectivity. The ability to reflect heat and light is twice that of hot-dip galvanized steel, with a reflectance greater than 0.75, which is better than the EPA Energy Star’s 0.65, making it an ideal building material for energy savings.

Roof Sheet Installation Process

Standard installation process for high quality Galvalume Corrugated Roofing Sheet.

  1. Pre-class safety training and technical delivery.
  2. Hoisting: According to the site conditions, the cranes should be selected reasonably according to the layout of the plates, and the number corresponding to the main ribs of the roof panels should be hoisted in order.
  3. The low cost Galvalume Corrugated Roofing Sheetwill normally be directly hoisted from the truck to the roof installation, such as stacking on site, requiring no more than 6 heights per stack, stacked neatly.
  4. When lifting, hang the hook on the sling of the main rib of the plate surface, and use a special lifting hook.
  5. Check if the hook is sturdy before hooking. If there is any hidden danger, immediately inform the crane driver to re-hook.
  6. When lifting, the roof panel should be raised at a constant speed. In the process, it is forbidden to stand under the boom. Place the plates in accordance with the drawings and place them on the steel beams or supports.

Geomembrane Repair Method

hot sale hdpe geomembrane pond liner

When the hot sale hdpe geomembrane pond liner brings us profits, we should not forget to maintain the geomembrane, because each material has its own working limit, how to better maintain it. 

1. The patch should extend to at least thirty centimeters outside the area of the damaged geomembrane.

2. The patch material used to fill holes or fill the crack should be consistent with the geomembrane.

3. The work shoes worn by the construction personnel and the construction tools used should not damage the geomembrane.

4. All geomembranes and seams must be inspected. Defective geomembranes and stitching must be clearly marked on the geotextile and repaired.

5. For the safety of geotechnical materials, the packaging film should be opened before laying. And the geomembrane is tested for the appearance quality.

Galvalumed Steel Coil Characteristics

1. Heat reflective:
GL Galvalumed Steel Coil made in China have a high heat reflectivity, which is twice that of galvanized steel sheets, which are often used as insulation materials.
2. Heat resistance:
The aluminum-zinc alloy steel plate has good heat resistance and can withstand temperatures of more than 300 degrees Celsius. It is similar to the high-temperature oxidation resistance of aluminized steel sheets, and is often used in chimney tubes, ovens, illuminators and fluorescent lamps. Corrosion resistance:
The corrosion resistance of galvanized steel coils is mainly due to the protective function of aluminum and aluminum. When the zinc is worn, the aluminum forms a layer of dense alumina that prevents the corrosion-resistant material from further corroding the interior.
3. Economical:
Since the density of 55% of AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is larger than the area of ​​the plated steel sheet by 3% or more in the case where the weight is the same as that of the gold-plated layer.
4. Easy to paint
Excellent adhesion between galvanized sheet and paint, lacquered without pretreatment and weathering.
The coating of the gold-plated zinc-plated steel plate has excellent adhesion. Therefore, without the pre-treatment of the zinc plate such as Weathering, the characteristics of the galvanized plate can be directly coated on the advertising plate and the general plate.
5. Aluminized zinc plated steel has a silvery white ornate surface.
6. Galvanized steel sheets have similar processing properties and spray properties to galvanized steel sheets.

Roof panel waterproof design note

The high quality T-Type corrugated gl roofing sheet is not only the waterproofing requirement of buildings, but also an important measure to protect aerated concrete roofing panels. The coiling materials are still commonly used at home and abroad. Due to the narrow plate and the flat seam butt joint, the overall rigidity is poor. Therefore, if the linoleum is directly laid on the roof panel, the following points should be noted in the design:
1. The waterproof layer of aerated concrete roofing panel should have better overall rigidity in addition to its own waterproof performance. The overall rigidity of the board should be well connected with the main structure. Strengthen the joint between the side seams. If the gap is small and the general cement mortar is used for filling, the metal sheet subjected to anti-rust treatment should be nailed between the joints, or the mortar should be bonded.
2. In the flat roof, generally no slope is found on the upper part of the roof panel and the slope is determined by the structure. Only when the slope of the support is uniform and flat, the flatness of the board surface can be ensured, and the linoleum can be laid.
3. Before the aerated concrete roof panel is made of linoleum, there is generally no gas barrier layer in the upper part. The function of the gas barrier on the reinforced concrete roof is to prevent the moisture in the room from penetrating into the insulation through the reinforced concrete roof panel and affecting the insulation effect. However, the aerated concrete roof panel itself is the insulation material, so it is separated in the upper part. The gas layer has lost its meaning.

Geomembrane WeldingGeomembrane anti-seepag

Geomembrane Welding

Geomembrane anti-seepage geotechnical materials, presumably many customers should be familiar with it. One of the most concerned issues is the issue of high quality textured hdpe geomembrane welding. Today, we will introduce you to the welding of HDPE geomembrane in special parts. Let’s take a look at it:

1. Connection of dam pipe and geomembrane: Firstly, the HDPE geomembrane is cut into a trumpet-shaped pipe sleeve according to the diameter of the leachate through the dam pipe, divided into 6-8 small pieces, and then the pipe sets are ordered from large to small. The sleeve is inserted into the dam tube, and the position of the sleeve is adjusted appropriately and temporarily fixed by a hot air welding torch. The sleeve cannot be suspended, and finally the sleeve of the sleeve is welded to the HDPE geomembrane and the leachate through the dam tube. The geomembrane is reinforced with stainless steel hoops.

2. At the intersection of the slope of the reservoir area and the bottom of the reservoir, there are many blind trenches in the design. First, the HDPE geomembrane is laid along the dam surface at a distance of 1.5 meters away from the blind ditch and then connected to the base film. The welding of the adjacent two pieces is: first welded and then pressed into the blind ditch.

3. The intersection of the slope, that is, the bend of the dam slope: laying and welding are special cases. Special cutting according to the actual conditions can make the HDPE geomembrane close to the dam slope base, otherwise it will cause ��hanging�� or ��drumming�� phenomenon. In this area, the operator should carefully measure the HDPE geomembrane into an inverted trapezoid with a narrow upper and lower width.

Geomembrane Repair Method
1. In order to the safety of geotechnical materials, the packaging film should be opened before laying, that is, a roll, a roll, and high quality pond liner textured hdpe geomembrane inspection appearance quality.

2. The worn geomembrane must be repaired by laying and heat-bonding small pieces, the thermal connection must be strictly controlled to ensure that the patch and the geomembrane are tightly combined and not damaged.

3. Before the end of each day, visually inspect the surface of all paving materials on the day to ensure that all damaged areas have been marked and repaired immediately to determine that there are no foreign substances on the paving surface that may cause damage.

4. At the bottom of the landfill, if the crack exceeds 10% of the width of the coil, the damaged part shall be cut off and then the two geomembranes shall be connected. If the crack exceeds 10% of the width of the coil on the slope, the The geomembrane is removed and replaced with a new one for the bentonite waterproof blanket.
