Are you always looking for formulas when you're doing engineering, pricing, steel bands, steel structures, and counting weights, reporting budgets, checking in? Circle steel, screwd steel, pipe, corner steel, steel plate, trough steel, pieced steel, mix it up with more than one type, misweighting the material directly
Today, the most complete, field-based steel theoretical weight formula is assembled once and for all. It's easy to remember. Cell phones are checked. New hands can calculate steel weights in one second. The article is accompanied by an icon
I. General rationale
Steel density map
Unified density of all steel: 7. 85g/cm3 = 7850kg/m3 core logic: weight = volume x density, from which all model formulas are extrapolated, bearing in mind 7. 85, common benchmark values for all steel。
Ii. Steel bands (the most commonly used for civil construction)
Quantification of steel bands
A simple universal machine
(kg) = diameter (mm) x diameter (mm) x 0. 00617 example: Φ16 x 16 x 0. 00617 = 1. 58 kg/m common stenography: Φ10 = 0. 617 kg/m, Φ25 = 3. 856 kg/m application: hrb400 screwd steel, hpb300 round steel, wands, stretching
Conch / circle
The previous formula calculates the weight per metre, multiplied by the length of the whole disk; at the time of purchase, the merchant settles directly by theoretical weight。
Iii. Steel plate, iron plate, gravitation plate (ground pre-burial, steel structure)
Steel plate weight speed scale
Steel plate formula per square weight
Weight (kg/m2) = thickness (mm) x 7. 85 example: 10 mm thick steel plate 10 x 7. 85 = 78. 5 kg/m2 whole plate weight = area x per square weight example: 2 m x 1 m, 8mm steel plate 2 x 1 x 8 x 7. 85 = 62. 8 kg/m2 total weight: 125. 6 kg granular coefficient: after calculation of normal plate thickness x 1. 1 and 10 per cent increase in smoother tattoo weight
Iv. Plumbing types: seamless steel pipes, welding circuits
Plumb formula diagram
Round management weight (per metre)
Formula: formulae per metre weight (kg) = (outside diameter mm - wall thickness mm) x wall thickness mm x 0. 02466 example: dn50 steel pipe, outer diameter 60mm, wall thickness 3. 5mm (60-3. 5) x 3. 5 x 0. 02466 = 4. 88kg/m application: fire hose, drainage welding tube, seamless steel pipe, scaffolding truncheon
Angular steel (equivalent corner steel / unsegregated edge steel)
Angular steel specification weight table
Pyramid steel by weight (kg/m) = border width (mm) x border thickness (mm) 0. 00785 for example: 50 x 50 x 50 x 5 corner steel 50 x 5 x 0. 00785 = 19. 625 kg/m border steel: (long edge + short edge width - border thickness) x border thickness 0. 007856, trough steel, industrial type steel, h type steel (main, subbeam of steel structure)
Steel weight comparison table
1. Simple estimate of tank steel
Per metre weight = height x waist thickness x 0. 0078 (field rapid estimate, accurate national marker)
2. Craft/ h type steel
The engineering exercise did not recommend manual complex calculations, directly against the theoretical weight table of the national standard; the field feed was quickly accounted for using the manufacturer's own weight parameters。
Vii. Work site practical and small techniques, all formula calculations must be based on theoretical weight, with a >3% spread of steel overweight and a residual balance in the reconciliation; total steel bars: single weight x root number x length, plus 1,000 tons converted to facilitate material reporting schemes; mobile phone amplifications with 6 accompanying illustrations that can be calculated by hand without heavy weightings; steel price quotations, pre-burial processing, steel intakes, all of which can be checked against this formula to avoid overweight by suppliers。
The steel weight formula is a necessary food tool for dry work, whether it is a builder, a steel worker or a price budget. Stick steel 0. 00617, steel plate 7. 85, steel pipe 0. 02466 with three core coefficients, 90% of which are estimated directly by the weight of steel。
