Ductile gratings Botou City Wangwu Town Tianlong Castin 

Cast iron rain gratings are mainly used in some factories and even high-grade residential quarters, mainly because the concrete trench cover is often crushed, the road will often be destroyed. The use of steel grating made of rain grate can be applied to varying degrees of load. As the cast iron rain grate construction is relatively simple with the lighter weight, the better ability of load bearing, the stronger ability against impact, bending rather than breaking, and the larger water discharge, and it is easy to open and have a good anti-theft function, it is suitable for the use of factories and high-grade residential quarters. The load bearing capability of the rainwater grate is stronger; and generally, the standard size of the rain grate is selected and used for construction, and others can be customized. The rain is not only the cost of relatively low, but it is important that the anti-theft performance is better.

If the cast iron rainwater grate is made of bad material, the one who is harmed is not only their own, but also the passers-by and even the others and it will bring a variety of inconvenience and trouble to the traffic. Therefore, the manufacturer will produce pit covers and rain grate with conscience. Ensure the quality of the product on the safe and reliable, while the public praise is quite good and it is praised and trusted by customers consistently.

The cast iron rain grate is made of ductile iron, which has a very strong compression performance, very resistant to corrosion and anti-freeze crack; and it is a high performance and cost ratio a product with a very wide range of application, very low cost of production and it has a good anti-theft function as the anti-theft lock is provided inside it. The cast iron rain grate is a strong anti-ductility product, which can withstand very strong pressure and have a strong bearing ability; and it is a product of assurance. It is better in safety and environmental protection, pollution prevention and cost savings. The quality of the cast iron rainwater grate is tested and certified by the national quality inspection authority, and it can achieve the purpose of production and use. Because of its strong performance, it is more economic and the frequency of replacement is less, so as to save a large sum of expense for customers.

From the chemical composition and physical properties of view, the ductile iron, no matter in the tensile or elongation, or yield strength is higher than that of the gray cast iron; and the extreme load pressure head index determines that the performance of the ductile iron is higher than that of product made by other materials. There are a lot of covers facing the phenomenon of pilferage, because the ductile iron has a certain value of recycling. In the anti-theft aspects, a very good modification has been made in our ductile iron products. Using the form of a hidden door, it is connected by the fixed hole and the spring shaft and thrust fixing bayonet lock; a special lifting lock shall be inserted in and rotated clock wise for 90 degree and lift the cover when the lock door is retreated to during open and lifting manual lock is not necessary. This can achieve automatically locked state. It is simpler, more solid, more reliable and more convenient.

Features of ductile iron grate

1. It has an active anti-theft function, since there is not any recycling value.

2. The pattern and color can be customized according to the requirement of customers. The pattern is exquisite and the color is bright, which is a good product for enhancing the city grade and beautifying people’s life.

3. Noise will not be generated by rolling of the vehicle, which reduces noise pollution of the city.

4. The service life is long; it will not be corroded and rusted caused by the passage of time, and it will maintain a beautiful appearance for a long time.

5. Non-slip performance is good, and it will not become slippery because of rain, snow or other reasons.

6. It is resistant to compression, bending and impact and it is used for municipal, drainage, gardens, communications and community construction and other aspects.

7. The specification and size of the product can be customized according to the different demands of the customers; the product is easy to cut, easy for handling for the light mass and convenient for installation, which greatly reduces the input of the human and material resources; and according to the calculation, the loss can also be reduced and controlled to the lowest point.
