Safety hazard of steel structure grid
Time:2019/4/1 14:49:43      Click:1474

The steel structure grid is relatively popular, and the effect of the impact is also relatively ideal. The user's recognition of the grid project is high, but the general steel structure grid still has certain safety hazards, so it is necessary to make the steel structure grid in advance. Security measures.

Solve the fire hazard of the steel structure grid. When the temperature around the steel structure product reaches 430-540 degrees, the steel will be bent, the tensile strength will be reduced, and the bearing capacity will be reduced. Therefore, it is necessary to use refractory materials for product maintenance. It is recommended to apply paint or water to extinguish the fire, but the general effect is not very large, so it is necessary to install a fire protection device around the steel frame. Preventing the hidden dangers of the grid, generally including the whole and the part. If the steel structure grid is pressed, it will cause the loss of stability. Therefore, some changes in the load bearing and the defects of the steel will affect the supporting force, and the general grid will be affected. Supporting power is very important. To carry out lifting treatment, it is necessary to consider the lifting point reasonably to avoid imbalance.

The corrosion resistance of the steel structure grid is good. The corrosion resistance of the steel is generally poor, and it is easy to cause corrosion, which causes the bearing capacity to decrease. The maintenance is relatively complicated. Corresponding anti-corrosion measures can bring different effects. .
