Stainless iron classification

In a corrosive environment, the damage caused by the chemical or electrochemical action of the metal and the surrounding medium is called corrosion. In corrosive environments, corrosion can also occur when stainless steel is not properly selected.

Corrosion has many classification methods.

1. According to the nature of the action can be divided into chemical corrosion and electrochemical corrosion.

2. According to the form of corrosion, it can be divided into general (comprehensive, uniform) corrosion. The so-called general rot, the corrosion of the system is distributed on the entire stainless steel surface. The so-called local corrosion pitting, crevice corrosion, stress corrosion, corrosion fatigue, selective corrosion, Scour corrosion and so on.

3. According to the environment and conditions of corrosion, it can be divided into atmospheric corrosion, industrial water corrosion, soil corrosion, acid, alkali, salt corrosion, seawater corrosion, high temperature corrosion, (including liquid metal, molten salt, gas corrosion).

Biaxial Geogrid(bx geogrid) is made of high molecular polymer through extrusion, forming and punching before longitudinal and lateral stretching. This material has considerable tensile strength in longitudinal and lateral directions. This chain structure can effectively bear and diffuse forces on soil and is applicable to large area permanent load bearing foundation as a reinforce. 


1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ; 

2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction . 

3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;  

4. It is used in soft soil base reinforcement treatment ,  is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base; 

5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
