Because edging, different, actual weight and theoretical weight and cut holes will appear different. Weight in the industrial computing platform steel grating and steel grating delivery settlement, unified theoretical basis for the calculation of the weight. For the length is less than 1 meter steel grating (such as trench cover) or need for special edging steel lattice panels, due to the increased edging plate, the weight will increase. When using a planar flat steel edging, steel grating length not less than one meter, according to the following formula to calculate the theoretical weight of steel grating: Wt = (b1t1N1 + b2t2N2 + 2b3t3) ρμ formula: Wt- steel grating weight, g / m2 t1- load flat width, mm b1-- flat steel thickness, mm N1- per meter steel grating load flat number t2- rail width, mm b2- rail thickness, mm N2- per meter steel grid plate number t3- crossbar edging flat width, mm b3-- edging flat steel thickness, mm ρ- material density, g / mm3 surface treatment of steel density calculations μ-- gain coefficient of thermal press 7.85g / mm3 zinc dipping by 1.08 to calculate the weight gain
