1. Improve the surface flatness of high quality galvalume steel coating steel coil. After finishing, the flatness of the galvanized aluminum coil is improved, and the wave shape of the galvanized aluminum coil is partially eliminated, and the surface slag particles or other uneven spots can be flattened to make the surface smooth and flat. 

2. Adjust the roughness of the surface of the hot sale aluminum zinc steel coil. By controlling the roughness of the surface of the work roll of the finishing machine, the original uneven roughness of the surface of the galvanized aluminum plate can be unified to a certain range. This improves the paintability of the product and the lubricity during processing. 

3. Improve the surface color of high quality galvalume steel coating steel coils. For small zinc flower and zinc-free flower products, the galvanized aluminum plate can achieve a more uniform surface with gloss by finishing. For some private enterprises, the use of large zinc flower products as color-coated substrates can make the zinc flower bumps and different glosses formed by the large zinc flower crystals smooth and uniform, which makes the zinc flowers blurred and unfavorable. Cover the zinc flower when painting. 

4. Improve the processing of GL Galvalumed coil performance. By finishing, the yielding platform of the galvanized aluminum coil can be eliminated or become inconspicuous, and the metal slip line can be prevented from being generated in the subsequent processing.

It is understood that high quality PPGI prepainted galvanized steel coil is divided into two types of products: high-strength board and deep-drawing board. Faced with the strict requirements of customers on product performance indicators, technicians take root in production lines, solve technical problems, and rely on national-level enterprise technology centers and national physical and chemical inspection centers to continuously strengthen key indicators research and experiment of automobile plate strength, forming and welding.

When producing high-strength galvanized sheet, the technicians actively docked the market on the basis of stable production of 600MPa grade dual-phase steel and developed 800MPa grade high-strength steel. When producing deep-dip galvanized automotive panels, technicians overcome the problems of high elongation and high surface quality of the products, especially the ultra-deep O5 board surface requires zero defects. The technicians specially formulated the production guarantee measures: before the production, the whole line cleaned the roll surface and carefully checked the defect source; in the production, the surface quality was checked by means of the meter; after the product was off the line, the product was manually polished and then the product was inspected to ensure the product. Surface Quality.

The company's O5 board has produced and sold more than 1,000 tons for two consecutive months, and the contract fulfillment rate has reached 100%. Automobile panels have become suppliers and service providers of many well-known automobile manufacturers at home and abroad, and the products are moving towards high-end, high-quality and brand-oriented.

With the development of China's construction industry, the development of related building materials industry has also a broader development space. With its own unique advantages, hot sale prepainted color galvanized coil has been recognized by many users in the market.

The galvanized coil is cold rolled or hot rolled, and a thin layer of zinc is plated on the elongated steel coil. The production of hot sale prepainted galvanized steel coil concentrates on the advantages of both galvanizing and strip steel so that the product is not only corrosion-resistant, beautiful but also has high dimensional accuracy, good surface quality, easier processing, and material saving. The product can meet the requirements of the public to a certain extent, and can better meet the needs of users.

At present, the construction industry and the automotive industry in China have been continuously developing. The hot sale prepainted color galvanized coil has become a shortage of products in China, and the related manufacturers of galvanized coils in China are producing galvanizing according to the current market demand. At the time of the board, efforts have been made to extend its service life and to some extent reduce the shortage of resources.

The hot sale prepainted galvanized steel coil is fully in line with the needs of modern industry. It has been widely used in various industries such as building construction, wire and cable. The galvanized coil has stable performance, long service life and corrosion resistance, and is well received by consumers. The development prospect of high quality prepainted color galvanized coil is very broad, because in the development of industry, a galvanized coil is inseparable.

A. Hot rolled coil is a steel sheet heated by a billet. The thickness of wholesale hot rolled steel coil is between 2 mm and 13.5 mm. Generally, the price of hot rolled coil is cheaper than that of flat plate.

B. The raw materials of cold-rolled coils are the same as those of hot-rolled coils. The process of knowledge processing is different. The high quality cold rolled steel coil china is transformed into coil by repeated cold rolling, pickling and cold rolling. This kind of steel plate has a smaller scope of use and its price is cheaper than that of hot-rolled coils.

C. Galvanized steel coil, as its name implies, is coated with zinc metal on the surface of the steel plate. The main purpose of this is to prevent the surface of the steel plate from being corroded and to increase its service life. Galvanized steel coil can be divided into hot dip galvanized steel coil, high quality cold rolled steel coil china, composite galvanized steel coil and color galvanized steel coil according to different processing methods.

D. The high quality prepainted color galvanized coil is made of galvanized steel coil as the base material, repeatedly spraying paint on the galvanized coil, and then through complex processing procedures. This kind of roll has many colors, such as yellow, blue, red and white teeth. Because of the moderate price, it is widely used as wall and roof.

Some minor problems with China Galvanized Steel Roofing Sheet for sale are in our solution and handling. Today we have listed two more detailed issues - the waterproofing of the roof through the roof and the sealing of the double-sided roof.

Waterproof treatment of the rod wearing the roof
1. According to the different positions of the rods wearing the roof, according to the drainage conditions, different cutting methods are adopted respectively. The museum has two types of slitting and crosscutting.

2. The treatment method is mainly to add water retaining ring and waterproof with multi-channel polyurethane waterproof coating.

3. A single water-passing rod member is provided with a water retaining ring separately; a rod member that passes through the plate is arranged, and a series of water retaining rings are arranged along the longitudinal slit.

1. Wholesale GL steel sheet has sound insulation, good thermal insulation performance - porous foam core layer has good sound insulation and thermal insulation properties

2. Large area, light weight - light body materials, reduce building load

3. Rich in color, long-lasting stability - fluorocarbon paint coating, rich in color, smooth surface, acid and alkali resistance, mildew, rain as new

The 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 plates should be hosted in order.
3. The low cost Galvalumed steel plate will 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 high quality galvalume corrugated roofing sheet 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 sheet should be raised at a constant speed. In the process, it is forbidden to stand under the boom. Place the low cost galvalumed steel plates in accordance with the drawings and place them on the steel beams or supports.

What kind of anti-rust oil is used for the anti-rust treatment of corrugated roofing sheet incision? 

Customers who have high requirements on product appearance are mainly anti-rust treatments for hot sale color-coated corrugated roofing sheet cuts, stamped galvanized sheets, and some fresh cuts. If they are not treated with anti-rust treatment, the time is longer. It will rust, especially if some so-called emulsion is used in the stamping, the rust may be more serious. 

In order to balance efficiency and appearance requirements, the process flow is as follows: blanking - sheet metal forming - cleaning - anti-rust treatment - spraying - silk screen - assembly. In consideration of the anti-rust cycle and the salt spray test requirements, safety, conductivity, and thickness of the oil film should also be considered, and the hand should not be touched, and the subsequent assembly is not affected. 

If it is immersed in anti-rust oil, it is generally recommended to use water-based anti-rust oil (water-based anti-rust agent).

A new material for PP woven prevent grass growth geotextile, one of which, for finished fabrics, is typically 4-6 meters wide and 50 to 100 meters long. Non-woven fabrics have no latitude and longitude lines, are very convenient for cutting and sewing, and are light in weight and easy to shape, which is loved by manual fans. Since it does not require a fabric to be formed by weaving, but the short fibers or filaments of the textile are randomly arranged or oriented, a network structure is formed and then reinforced by mechanical, chemical or thermal bonding.

1. There are needle-punched nonwoven geotextiles and spunlace, short and long fibers.

2. Rrefers to geotechnical cloth geotechnical engineering. It means that no weaving of the nonwoven fabric is required during the manufacturing process.

3. Some geotextiles are not required to be made into so-called woven, non-woven geotextiles. Non-woven, but can be used in a wide range, like our non-woven fabrics in the heart of Indian wipes, as well as the hotel's sneakers, and non-woven fabrics. Polypropylene is a geotextile. Polypropylene geotextiles have excellent water permeability, filterability and durability, and can be widely used in railways, highways, sports halls, dams, hydraulic structures, tunnels, beach coatings, cofferdams, and environmental protection projects.

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 geomembrane is removed and replaced with a new one for the bentonite waterproof blanket.

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 high quality textured 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 high quality textured 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 high quality textured hdpe geomembrane into an inverted trapezoid with a narrow upper and lower width.
