Product Description

From the name, you can guess the intended use of the Tank brand heavy duty locked grating. This is a heavy duty locked grating with a deeper or thicker bearing bar. The size of the cross bar is also adjusted accordingly.

At the same time, the cross bar also has a reverse groove, which provides additional stability to the heavy duty locked grating, so it can easily withstand surface loads of more than 50 tons and wheel loads of 10 tons.

We can also achieve higher loads by increasing the grade of steel. For specific situations, it is recommended to contact our technicians before designing the drawings. We will provide a reasonable and economical design solution free of charge.
