What are the common types of steel sheet?

According to a fixed method
A: screw penetration type - fixed by the self-tapping screw directly through the hot sale color-coated corrugated roofing sheet on the purlin;
B: Dark button type - no screws on the surface, the roof panel is fastened to the support fastener by machining tolerances;
C: bite type I - the surface roof sheet is connected to the support by crimping, but the panel and the panel can slide relative to each other between the panel and the support;
D: Bite type II - The surface roof panel is connected to the support by crimping, but there is no relative sliding between the panel and the panel, and between the panel and the support.

Effect Of The Use Of Geomembrane

The effect of the use of [url=https://www.dk-geosynthetics.com/pond-liner-hdpe-geomembrane/]dam liner/fishing farm/shrimp liner Hdpe geomembrane[/url] is actually different for the use of this material in different places, especially in some relatively large buildings, the use of this material will be specially purchased, and the material is in use. It is very convenient, it doesn't take too much time when laying, and some machines may be welded to this material in different projects, making it very easy to weld and the effect It is also very good.

The effect of the use of geomembrane is actually different for the use of this material in different places, especially in some relatively large buildings, the use of this material filament silk cloth will be specially purchased, and this The materials are very convenient when used, and do not need to spend too much time when laying. At the same time, some machines may be welded with this material in different projects, making it very easy to weld. And the effect produced is also very good.

Nowadays, emerging products are not only supported by the state, but also very popular among business owners, especially the composite geomembrane that has emerged in recent years. It is produced by international standards, and its quality is stable and reliable. At present, researchers combine advanced production technology. , various practical parameters, developed a dozen geotechnical materials including composite geomembrane, geotextiles according to the actual engineering needs of processing characteristics and functions, expanded the geotechnical material family, injected new engineering projects Elements, so choose high-quality, safe and reliable composite geomembrane, and also inject new blood into the company.

Requirements for the laying of filament geotextiles1. The

Requirements for the laying of filament geotextiles

1. The slope of the seam line that should intersect; the balance of the toe may be local or stress, and the distance of the horizontal joint must be greater than 1.5 m;
2. Main inspection: check whether it is deep into the grassroots, solid, if there is any foreign body, there should be no proper treatment;
3. Geotextile factory installation notes:
a. It is also possible to use a long fibre filament needle punched geotextile in stock cutting knife (knife hook) or scissors to cut, as a cutting part, special protective measures for other materials to be taken, due to cutting the filament geotextile to prevent unnecessary damage;
b. The connection between the filaments and geotextiles must pay attention to the following: Under normal circumstances, there should be no horizontal connection (the connection profile should not intersect along the slope) unless the slope of the patch is used;
c. Kinds of filament geotextile uses, such as sutures, such as or more than geotextile materials should be sutured to maintain chemically resistant UV suture material should be the same. And the filaments of the suture filaments should have a clear color and check.

What Is The Benefits Of Galvanized Steel?

In recent years, with the emphasis on dust suppression in China, the application of dust suppression networks has increased. Basically, the wind and dust suppression nets are mainly made of high quality GL galvanized steel coils. It has also been mentioned that rust prevention of galvanized sheets is also mentioned. Better performance and the need for galvanized sheets for wind and dust screens. So which of these two materials is better?

The difference between the two is the difference in surface

The difference between hot sale galvanized steel coil and high quality GL Galvanized Steel Coil is mainly due to the difference in the coating. The surface of the galvanized sheet is evenly distributed with a layer of zinc material, which has an anodic protection effect on the substrate, that is, the zinc material replaces the substrate to corrode and rust. The metal is protected and the internal substrate is damaged only when the zinc is completely corroded.

The surface of the aluminum zinc steel coil in stock is about 55% aluminum, 43.5% zinc and a small number of other elements. Under the watch, the surface of the galvanized layer is a honeycomb structure, and the "honeycomb" made of aluminum is wrapped with zinc. In this case, although the aluminum-zinc plating also functions as anode protection, on the one hand, since the zinc content is reduced, on the one hand, the zinc material is wrapped with aluminum, and electrolysis is not easily generated. Therefore, the effect of the anode protection is greatly reduced, so once the galvanized sheet is cut and substantially loses protection at the cutting edge. In this case, it will rust quickly, so the galvanized sheet should be cut as little as possible.

Galvanized Steel Coil made in China is the metal materials we often use. Galvanized sheets for wind and dust screens are hot dip galvanized sheets. The hot dip galvanizing treatment will cover the surface layer of the steel sheet having a thin zinc layer. Effectively prevents air and moisture from entering and prevents an internal substrate from rusting.

In cities where the air is humid and the rain is abundant, once a certain point of the galvanized sheet is rusted, if the measures are not taken in time, the rust will become larger and larger until the entire surface; and the high-quality GL galvanized steel coil will rust evenly and will not cause diffusion.

After comparing the two, it can be seen that the Galvanized Steel Coil made in China is superior in terms of service life and corrosion resistance, and the price of the galvanized sheet is also lower than that of the galvanized sheet. Therefore, it is recommended that you choose windproof and dustproof. The material of the mesh should be galvanized as much as possible.

Filament geotextile paving method

Filament geotextile paving method

1. Using a manual or mechanical roll shop; the high quality long fibre filament needle punched geotextile is smooth and the left margin is modified as appropriate;
2. Filament geotextiles usually overlap, several methods of stitching and welding, the width of stitching and welding is usually 0.1 m or more, and the overlap width is usually 0.2 M or more. Possible long-term exposure of geotextiles should be welded or stitched;
3. The filament geotextile method can also be connected by hot air welding. The two fabrics are connected by a heat gun at a moment of high temperature heating to partially realize the molten state, and immediately have a certain force, so that they are firmly adhered together and cannot be connected. To wet heat bonding (rain or snow) weather. For a minimum width of 10 cm suture, the minimum width of the lap is naturally 20 cm, when hot air is welded to a minimum width of 20 cm for the seam
4. Sewing with the same quality and geotextile, materials that are resistant to chemical attack and UV radiation are more resistant to sutures;
