The Selection and Maintain of Colored Stainless Steel Sheets  

----Keep colored stainless steel sheets as new after years of use

The colored stainless steel sheets are widely used in construction industry, especially play an important role in building steel structure warehouse, making corrugated steel roof and producing color steel sandwich panel, which all need a long service life to ensure safety and carefree use. So, the question remains, How to choose and buy high-quality colored stainless steel sheets, and how do we keep them as new after years of use?

Methods of Picking Out High-quality Colored Stainless Steel Sheets 

1.Choose Hot Galvanizing foundation steel sheet

There are three kind of foundation sheet of colored stainless steel sheets: colored hot galvanizing foundation sheets, color coated cold rolling base steel sheets and colored electricity galvanizing steel sheets. 

For construction industry, the colored hot galvanizing foundation sheet is absolutely the best. Advanced hot galvanizing technique make sure it has thicker zinc coating than others, besides, the organic coating on the surface can also protect the steel plate from being corroded. Unlike color coated cold rolling base steel sheets, the colored hot galvanizing foundation sheets will not rust quickly after a few tiny scratch. These unique double protections ensure colored hot galvanizing foundation sheets a long service life in the complex outdoor environment.

2.Customize the Coating by your needs

Paint layer and zinc coating are the key factors which can directly determine the service life of colored stainless steel sheets. Choose proper amount of zinc coating and paint materials by needs can help you to pick out the most cost-effective products, which will not only fit the needs, but also save costs.

The amount of zinc coating mostly decides the anti-corrosive property of colored stainless steel sheets. The thicker the zinc coating layer, the more difficult it is for corrosive substance to penetrate the coating to corrodes the steel plate, and the better the anti-corrosive property of colored stainless steel sheets. Choose the proper coating thickness according to the local environment. Hot galvanizing technology can be used for galvanize pure zine and zinc aluminum alloys, the specific choice of mental types of coating is mainly depends on the outside PH value. The performance of pure zinc coating is better than that of zinc aluminum alloy coating in alkaline environment, but the reverse in acidic medium.

There are four main types of painting layer: Polyester, polyurethane, silicon modified polyester and high durable polyester. Polyester is the most commonly used coating, it has good hardness and malleability and a moderate price, but only mediocre durability. Compared with polyester, the durability, lustrousness and color longevity of silicon modified polyester are improved, but its malleability is slightly reduced. High durability polyester not only has the advantages of polyester, but also good malleability, which is cost-effective.

3.Purchase from reputable and large-scale companies

In general, reputable and large-scale companies has professional production lines and experience,  their standardized production and quality testing process can ensure the quality of products of  stability and reliability. The product performance may not meet the requirements if there are some tiny deviation of the thickness of painting layer or zinc coating.

Colored Stainless Steel Sheets Maintenance Methods

Although colored stainless steel sheets has stable physical properties and relatively long service life, they also need maintenance measures to keep good look and cleanliness. There are many outside factor which can influence the service life of these steel sheets, such as climate, temperature, air quality, frequency of cleaning, the PH of rainwater, etc. The service life of colored stainless steel sheets with the same amount of galvanizing, the same type of painting and  coating thickness could be very different when it comes to the different district and usage part.

Increasing the gradient of roof and flushing with water is effective ways of extending the service life of colored stainless steel sheets. The more inclined the roof is, the less likely it is to accumulate dust and other dirt, and the longer of its service life.
