Learn the math, give you the length, width and height, can you calculate the weight of the steel bar?
NoNo!!! Do you understand how the weight of reinforcement is calculated? Remember the formula below, you can calculate it properly without math!
There are many types of reinforcement, and the weight calculation method of different types of rebar in different shapes is also different.
<h1>Threaded reinforcement</h1>
(1) Introduction:
Rebar is a common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar consists of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words hot rolled ( Hot rolled ) ( Ribbed ) , and bar ( Bars ) respectively.
(2) Weight calculation formula:
Diameter mm× diameter mm× 0.00617 × length m
Example: Rebar Φ20mm (diameter) ×12m (length)
Calculation: 20×20× 0.00617×12 = 29.616kg
<h1>steel tube</h1>
The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of oil in the early 19th century, the manufacture of ships, boilers and aircraft during the two world wars, the manufacture of thermal power boilers after World War II, the development of the chemical industry and the drilling and transportation of oil and gas, all of which have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.
Formula: (outer diameter - wall thickness) × wall thickness mm× 0.02466× length m
Example: Steel pipe 114mm (outer diameter) ×4mm (wall thickness) ×6m (length)
Calculation: (114-4) ×4×0.02466×6=65.102kg
<h1>Bar</h1>
Round steel refers to solid strips of steel with a round cross-section. Its specifications are expressed in millimeters in diameter, such as "50" which means round steel with a diameter of 50 mm.
Formula: Diameter mm× diameter mm× 0.00617× length m
Example: Round steel Φ20mm (diameter) ×6m (length)
Calculation: 20×20×0.00617×6=14.808kg
<h1>Flat steel</h1>
Flat steel refers to steel with a width of 12-300 mm and a thickness of 4-60 mm, with a rectangular section and a slight edge.
Formula: Side width (mm) × thickness (mm) × length (m) ×0.00785
Example: Flat steel 50mm (side width) × 5.0mm (thickness) ×6m (length)
Calculation: 50×5×6×0.00785 = 11.7.75 (kg)
<h1>Hexagonal steel</h1>
Angle steel is a type of section steel, also known as hexagonal bar, the cross-section is a regular hexagonal bar.
Formula: Counter-edge diameter×-to-edge diameter× length (m) ×0.00068
Example: Hexagonal steel 50mm (diameter) ×6m (length)
Calculation: 50×50×6×0.0068=102(kg)
<h1>armor plate</h1>
Steel plates are divided according to thickness, thin steel plates < 4 mm (the thinnest 0.2 mm), thick steel plates 4-60 mm, extra thick steel plates 60-115 mm. The width of the thin plate is 500-1500 mm; the width of the thick plate is 600-3000 mm.
Formula: 7.85× Length (m) × Width (m) × Thickness (mm)
Example: Steel plate 6m (length) × 1.51m (width) × 9.75mm (thickness)
Calculation: 7.85×6× 1.51×9.75= 693.43kg
<h1>Fangtong</h1>
Fangtong is mainly used for welding shelves, curtain walls, decorative decoration, machining, steel structures, daily necessities and so on.
Formula: Side width mm×4× thickness× 0.00785 × long m
Example: Fangtong 50mm×5mm thick×6m (length)
Calculation: 50×4×5×0.00785×6=47.1kg
<h1>Square steel</h1>
Square steel belongs to the modern word, refers to a square material that is hot rolled out of a square billet, or a square material pulled out by a round steel cold drawing process.
Formula: Side width (mm) × side width (mm) × length (m) ×0.00785
Example: Square steel 50mm (side width) ×6m (length)
Calculation: 50×50×6×0.00785=117.75(kg)
<h1>Equilateral angle steel</h1>
Equilateral angle steel is an angle steel with equal sides, and the theoretical weight of equilateral angle steel is calculated in the unit of measurement of kilograms (kg).
Formula: Side width mm× thickness× 0.015× length m (rough calculation)
Example: Angle steel 50mm×50mm×5 thickness×6m (length)
Calculation: 50×5×0.015×6 = 22.5kg (table is 22.62)
<h1>Unequal angle steel</h1>
As opposed to two equal-sided angle steels with equal sides, it refers to male angle steels whose cross-sections are right-angle L-shaped and the two sides are not equal in length.
Formula: (side width, side width) × thickness× 0.0076× long m (rough calculation)
Example: Angle steel 100mm×80mm×8 thickness×6m (length)
Calculation: (100 80) × 8×0.0076×6 = 65.67kg (Table 65.676)
<h1>Brass tube</h1>
A type of non-ferrous metal tube, is a pressed and drawn seamless tube. Copper pipes are robust and corrosion resistant, making them the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housings. Brass pipes are the best water supply pipes.
Formula: (outer diameter - wall thickness) × thickness× 0.0267× length m
Example: Brass tube 20mm× 1.5mm thick×6m (length)
Calculation: (20-1.5) × 1.5×0.0267×6 = 4.446kg
<h1>Copper tube</h1>
Also known as copper pipe. A kind of non-ferrous metal tube. It is a pressed and pulled seamless tube. Light weight, good thermal conductivity, high low temperature strength. Commonly used in the manufacture of heat exchange equipment (such as condensers, etc.).
Formula: (outer diameter - wall thickness) × thickness× 0.02796× long m
Example: Copper tube 20mm× 1.5mm thick×6m (length)
Calculation: (20-1.5) × 1.5×0.02796
The above is the calculation method of the weight of the steel bar, absolutely practical dry goods, maybe one day you can use yo, collection collection!
