Grating price formula: Grating price formulas [1] the weight of steel grating means after edging and surface treatment (excluding non-surface treatment) after the theoretical weight. Because edging, steel grating openings and different cuts, the actual weight and theoretical weight will be different. Weight in the industrial computing platform steel grating and steel grating delivery settlement plant steel grating, unified theoretical basis for the calculation of the weight. According to the following formula to calculate the theoretical weight of steel grating: Wt = (b1t1N1 + b2t2N2 + 2b3t3) ρμ × 10-6 .................. (1) Where: Wt- steel grating weight, in kilograms per square meter ( kg / m2); t1- carrying flat width in millimeters (mm); b1- flat bearing thickness, in millimeters (mm); N1- per meter flat steel grating in the number of hosts; t2- cross pole width in millimeters (mm); b2- crossbar thickness, in millimeters (mm); N2- per meter steel grating in the number of rail; t3- edging flat width in millimeters (mm) ; b3-- edging flat steel thickness, in millimeters (mm); ρ- material density, in kilograms per cubic meter (kg / m3); steel density calculated according to 7850kg / m3; μ-- surface treatment weight gain coefficient ; hot-dip zinc weight gain is calculated as 1.06 surface treated steel grating: galvanized, cold galvanizing, electro galvanizing, painting, anti-rust oil dip, dip, not processed. Steel grating Feature 1: High strength, light weight, 2: anti-corrosion ability waterway steel grating, durable, 3: appearance, glossy surface; 4: The plot is not dirt, not plot rain and snow, not water Shaped steel grating, self-cleaning, easy maintenance 5: ventilation, lighting, cooling, slip-proof good 6: Easy to install and dismantle Grating Product Specifications 1. Bar Pitch: General for 30,40,60 (mm ); and non-standard pitch: 25,34,35,50 and so on. 2. The bar spacing: General for 50,100 (mm); there are non-standard pitch: 38,76 and so on. 3. Width: 20-60 (mm); 4. Thick: 3-50 (mm).
