Corten Steel Garden Edging

A variety of materials are often used in construction, and weatherproof steel is one of them. So what kind of material is the weather-resistant steel plate? What are its characteristics? Let's take a look at it right away. What is the weather-resistant steel plate made of? Weathering steel refers to the steel that is resistant to atmospheric corrosion and belongs to the low alloy steel between ordinary steel and stainless steel. In ordinary carbon steel, add a small amount of copper, nickel and other corrosion resistant elements made of weathering steel, with toughness, ductility, wear resistance, high temperature resistance, fatigue resistance and other characteristics, weather resistance can reach 2-8 times of ordinary carbon steel, with rust prevention, corrosion resistance, prolonging life, energy-saving and other advantages. Wear-resistant steel is commonly used for riveting and welding structural parts of vehicles, containers, buildings and other structures. When used for welding structural parts, the thickness of the steel is less than 16 mm. Weathering steel for welding structure has better welding performance than high weathering structural steel, which is used for welding structural parts of Bridges and buildings. What are the characteristics of weather resistant steel plates? Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with ordinary stainless steel, weathering steel is rich in trace alloying elements such as phosphorus, copper, nickel, vanadium, titanium and so on. The total amount of alloying elements is only a few percent of the total content, while stainless steel can reach ten percent, so the price is cheaper than ordinary stainless steel. A dense protective film is formed on the surface of the weather-resistant steel plate, which can protect the matrix under the rust layer and greatly reduce the corrosion rate. The amorphous oxide layer formed between the rust layer and the substrate is dense, because this dense oxide film can prevent oxygen and water in the atmosphere from penetrating into the steel, greatly improving the corrosion ability of steel materials. The steel grade that is resistant to corrosion, prolonging life, saving labor and reducing consumption is also the steel grade that can be integrated into the new mechanism, new technology and innovation of modern metallurgy.

Weather-resistant steel plate is a kind of natural weather-resistant steel steel with atmospheric corrosion resistance, characteristic corrosion and oxidation, which is constantly obtained in many fields. The common basic properties and the state of various weather resistant steel plates have been well reflected in the construction. At present, it is mainly used for welding and manufacturing of traffic vehicles, construction machinery, Bridges, towers, containers, steel containers and other low-alloy structural steels. Features: strong and tough, rust resistance, corrosion resistance, thinning and consumption reduction, energy saving.

However, for anything it always has two sides, also has advantages and disadvantages, for weather-resistant steel is its advantages and disadvantages dialectical view, and therefore selective application.

First, the advantages of weather-resistant steel plate for garden landscape

1, high visual performance

Weathering steel will change over time. Its color brightness and saturation are higher than that of ordinary construction materials, so it is easier to stand out in the context of garden greenery.

2. Strong body shaping force

The weather-resistant steel plate is relatively easy to shape into a rich variety of shapes, and can maintain excellent integrity.

3. Good spatial definition

The use of very thin weather-resistant steel plates to clearly and accurately separate the space, making the site concise and bright.

4. Historical language

With the aging of time, the unique color and texture of the beautiful weather-resistant steel plate can reflect the unique artistic charm and trace the historical sense of the site, record the instant sense of time, and extend the vitality of the site.

Second, the shortcomings of weather-resistant steel plates used in garden landscapes

1. Corrosion of welding points

The oxidation rate of the welding points must be the same as that of other materials, which requires special welding materials and techniques.

2, water corrosion

Weathering steel plate is not stainless steel plate, if there is water in the concave position of weathering steel, the corrosion rate will be faster, so it must be well drained.

3. Salt-rich air environment

Weather-resistant steel plate is more sensitive to salt-rich air environment. In such an environment, the surface protective film may not prevent further internal oxidation.

4. Fade

The rust layer on the surface of the weather-resistant steel plate can make the surface of the object near it become rusty.

5. Maintenance processing

The rust prevention and various patterns and colors that need to be dealt with are more delicate, more troublesome to deal with, and the price of many treatments is relatively expensive.

From the current development point of view, for the time being, there is no better material that can replace weather-resistant steel. Although the weather-resistant steel plate has shortcomings, it has to be admitted that it is really suitable for garden landscape, and we also look forward to improving it in the future development and using other technologies to make up for its shortcomings.

Weathering steel Garden edging corrodes like ordinary steel at first. After a period of corrosion, due to the enrichment of Cu, P and other trace elements on the steel surface, a dense amorphous rust layer is formed, and the matrix is very firm. This layer of stabilized rust can resist the intrusion of atmospheric moisture and harmful ions to a certain extent, prevent further corrosion of the base metal, and there will not be as much rust water as you see.
