Steel Grating Tolerance Range to Guarantee the Product Qualified

When the steel grating is manufactured there would be tiny mistakes. These mistakes would cause the products not perfect. However the mistakes are inevitable during the machine manufacturing. Then there should be a range that allows the mistakes happen. The tolerance for the steel grating could make sure that the product is qualified.

The tolerance of the steel grating size.

  1. The length tolerance of the steel grating is ± 5 mm, the width tolerance of the steel grating is ± 5 mm.
  2. The steel grating size would be influenced during the hanging and the carrying. And the detachable steel grating size is influenced by the weight limit we the workers carry the goods.
  3. The tortuosity of bearing bar should not be more than the 10% width of the bearing bar.
  4. The cross bar position deviation. The surface of the cross bar should not be more than 1 mm of the bearing bar. The both sides of the cross bar should not be over 2 mm of the steel grating sides.
  5. The cross bar and its pitch tolerance. The cross bar edge tolerance for the steel grating centre should not be more than 5 mm. The cross bar pitch tolerance should be ± with 1500 mm.
  6. The lengthways bending degree should not be more than the 1/200 of the length.
  7. The crosswise bending degree should be less than the 1/100 of the width.
  8. The tolerance of the diagonal.
The drawing shows the tolerance of the bearing bar and the cross bar.
The tolerance range of the bearing bar and the cross bar could make sure the steel grating is eligible.
The drawing shows the cross bar pitch tolerance is ± 6 mm.
The cross bar pitch tolerance range should not be more than 6 mm.
The drawing shows the bending steel grating.
The tolerance of the steel grating bending should not be more than the 1/200 of the length.
The drawing shows the bending of the cross bar.
The tolerance of the cross bar bending should not be more than the 1/100 of the bearing bar pitch.
The drawing shows a steel grating sketch map and on the map writes the tolerance range.
The diagonal tolerance range for the steel grating is ± 5 mm.
