Steel Grating Standard YB / T4001.1-2007 have pointed out that the steel grid plate size, shape and tolerances: a steel grating length to allow deviation, width tolerance of ± 5mm. 2 any piece of steel grating dimensions are subject to shop lifting and handling the force limit, removable planks need to consider the size of the manual handling of the weight limit. 3 does not verticality flat load should not exceed 10% of the flat width. 4 crossbar positional deviation: the rail surface shall not exceed the load on flat surface 1.0mm; both ends of the crossbar shall not exceed outer face flat steel grating on both sides of 3mm. 5 rail deflection and pitch deviation: the edge of the crossbar deflection of steel grating center should be less than 5mm: 1500mm at any length, steel grating stair treads, both ends of the bar spacing to allow deviation of soil 6mm. 6 longitudinal bending: Portrait of the deflection of steel grating should not its length of 1 / 200.7 lateral bending: lateral bending deflection of steel grating (before the edging) should be less than 1 / 100.8 pairs angle of the width Line bias: steel grating caused due to dimensional tolerances relative deviation diagonal, not ± 5mm.
