How to check paint thickness of steel structure? Linshang LS220 paint thickness gauge can be used to test the paint thickness of steel structure.

       In China, most of the factories are build in steel structures. At present, the common method for steel structures anticorrosion is galvanization. Steel structure anti-corrosion paint generally needs to brush primer, intermediate paint, top coat. And the indoor and outdoor requirements of steel paint thickness are also different. So how to check paint thickness? We recommend you Linshang paint thickness gauge.

1. The application of anticorrosive paint on steel structure surface     

       The conventional steel structure plants generally do not have special anti-corrosion requirements. But in some special industries, the anti-corrosion requirements of steel structure plants are relatively high. Industries such as printing and dyeing, chemical, paper and coastal construction. Anti-corrosion requirements of these places are relatively high.

2. Why is it necessary to measure the anticorrosive paint thickness on steel structures

       Steel structure is one of the main structural forms of civil engineering. Steel structure is easy to manufacture and has good plasticity, toughness and short construction period. Therefore, steel structure is widely used in various industries. 
       However, the corrosion resistance of steel structures is poor. After being corroded, the strength and bearing capacity of steel structures will decrease, and the safety and durability of steel structures will be seriously affected. Therefore, do anticorrosive coating work and use paint thickness gauge to measure the paint thickness is an important task to check whether the anticorrosive paint is qualified. 

3. The advantage of Linshang paint thickness gauge

(1) Fe and NFe measurement modes 

       At present, the paint thickness gauge has two types: single use and iron-aluminum dual use. The Linshang coating thickness gauge uses both the Hall Effect and the eddy current principle. It is an iron-aluminum dual-use instrument that automatically recognizes the substrate and switches between iron-based and non-ferrous-based measurement modes.

(2) Large measurement range

       The test range of Linshang paint thickness gauge mainly includes 0-2000μm and 0-5000μm. The paint thickness gauge of 2000μm range is suitable for the thickness detection of steel structure anti-corrosion coating. The paint thickness gauge of 5000μm range is suitable for the steel structure with anti-corrosion and fire protection.

(3) Separate and integrated

       The integrated type that can be operated with one hand.The split-type paint thickness gauge that is more suitable for measurements in narrow spaces and higher or lower positions,making reading and operation more convenient.

(4) Wear-resistant probe

       The ruby probe is wear-resistant and corrosion-resistant, which makes the service life of the paint thickness gauge longer and avoids the error due to probe wear.

4.  How to check paint thickness of steel structure?

   (1)Use an uncoated or unpainted steel structure or zeroing iron plate for zeroing adjustment.
   (2)Press the zero-adjusted paint thickness gauge vertically on the anti-corrosion steel structure workpiece. 
   (3)As shown in the figure above, the paint thickness of the anti-corrosion paint is 727um.
        At present, the coating thickness gauge has two types: single use and iron-aluminum. The test range of Linshang coating thickness gauge mainly includes 0-2000μm and 0-5000μm. The coating thickness gauge of 2000μm range is suitable for the thickness detection of steel structure anti-corrosion coating. The coating thickness gauge of 5000μm range is suitable for the coatings with anti-corrosion and fire protection.
