- The first difference is in the amount of zinc.
The main customers of the thorn rope factory are still targeted at farms and plantations, because the demand for thorn rope is often very large.
After the column is installed and secured, the net can be connected directly to the Internet. The tools required for this step must be special spanner, casing and matching screws. Stand the net in the middle of the two columns, and then force upward to align the net with the connecting accessories of the column.
Some large roll galvanized wire products in order to meet different industrial needs, will be further processed on the surface, such as the anti-corrosion layer, galvanized, iron plating, aluminum alloy plating, or in the galvanized wire appearance above the copper plating, brass plating, etc., to strengthen the steel wire and colloidal years and capabilities. Generally, galvanized wire products should be well plated and drawn when they are produced, and the sequence of the two processes should be decided according to the production or industrial needs.
- Galvanized iron wire is divided into hot-dip galvanized wire and cold galvanized wire, using low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, hot-dip galvanized, cooling and other processes. With good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can cut off the tie wire used in the building, the length is 20cm 30cm 40cm, can be cut off according to the requirements.

River isolation network because of different regions are not close to the same, some places called river guardrail network, reservoir isolation network and called river bridge guardrail and so on, but they refer to the same kind of product, we all know that the river isolation network fence itself is a kind of obstacle, to prevent people and cars falling into the river, if installed river isolation network will not appear such a problem, Its setting is conditional, generally in the river fence set guardrail and more people and vehicles installed guardrail maintenance, the relative risk of discrimination. As long as the correct planning, guardrail to play its own function and advantages. Today, I will introduce to you the style of the river isolation network.

If the requirements are higher, and it is humid place, it is recommended to use hot-dip galvanized barbed rope, although the price is higher, but the service life is longer, generally speaking, it is more cost-effective.

Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.

The steel mesh improves shock resistance and crack resistance. The longitudinal and transverse steel bars of the welded steel mesh constitute a network structure. Therefore, the bond anchorage between the steel mesh and concrete is good, and the load distribution is uniform, which significantly improves the earthquake resistance and crack resistance of the reinforced concrete structure. According to the practice test, the cracks of welding net are reduced by more than 75% than that of manual binding net. Greatly reduce the unnecessary cost of the construction process, shorten the construction cycle, the use of steel wire mesh is simple and convenient, easy to transport.

Choosing the wrong materials for an oil seal may result in premature wear, lip hardening, cracks, swelling, and subsequent expensive damage to the machinery in which the seal is used. It is therefore vital to gather all relevant data and consult with experts before purchasing to match the right type of oil seal with your application.

Even though it’s better than other materials in terms of toughness and wear time, it is preferably used in dry-running applications. The salient demerit of this material is its cost.
Factors in Oil Seal Selection
Oil seals, also known as grease seals or shaft seals, are essential components in many machines and systems. They play a crucial role in preventing the leakage of oil and other lubricants, ensuring the smooth and efficient operation of various mechanical parts.
Construction of an Oil Seal
Rubber covered
Pressure - Many oil seals can only withstand low-pressure applications, so understanding the compression set of your components is key.

Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
Amongst the several applications of oil seals, these are the most common three applications – o-rings, spring seals, and lip seals.
