Steel structure house material quality calculation
Quality calculation standards for different materials
Angle steel: weight per meter = 0.00785* (side width + side width - side thickness) * side thickness
Round steel: weight per meter = 0.00617 * diameter * diameter (rebar and round steel are the same)
Flat steel: weight per meter = 0.00785 * thickness * side width
Pipe: weight per meter = 0.02466 * wall thickness * (outer diameter - wall thickness)
Plate: weight per meter = 7.85 * thickness
Brass tube: weight per meter = 0.02670 * wall thickness * (outer diameter - wall thickness)
Copper tube: weight per meter = 0.02796 * wall thickness * (outer diameter - wall thickness)
Aluminum tread plate: weight per square meter = 2.96 * thickness
Non-ferrous metal specific gravity: copper plate 8.9 brass plate 8.5 zinc plate 7.2 lead plate 11.37
The calculation formula for non-ferrous metal sheets is: weight per square meter = specific gravity * thickness
The theoretical weight of steel is calculated in kilograms (kg). The basic formula is: W (weight, kg) = F (breaking area mm2) × L (length, m) × ρ (density, g/cm3) × 1/1000
The density of steel is: 7.85g/cm3,
The theoretical weight calculation formula for various steels is as follows:
Round steel wire rod (kg/m) W= 0.006165 ×d×d ,d = diameter mm
Rebar (kg/m) W= 0.00617 ×d×d ,d= section diameter mm
Square steel (kg/m) W= 0.00785 × a ×a , a= edge width mm
Flat steel (kg/m) W= 0.00785 ×b ×d , b= side width mm, d= thickness mm
Hexagonal steel (kg/m) W= 0.006798 × s × s , s = distance to the side mm
Octagonal steel (kg/m) W= 0.0065 × s × s , s = distance to the side mm
Equilateral angle steel (kg/m) = 0.00785 × [d (2b – d ) + 0.215 (R2 – 2r 2 )] : b= edge width, d = edge thickness, R = inner arc radius, r = end arc radius
Unequal angle steel (kg/m) W= 0.00785 ×[d (B+b – d )+0.215 (R2 – 2 r 2 )] : B= long side width, b= short side width, d= side thickness, R = inner arc radius r = end arc radius.
Channel steel (kg/m) W=0.00785 ×[hd+2t (b – d )+0.349 (R2 – r 2 )] h= high, b= leg length, d= waist thickness, t= average leg thickness, R = inner arc radius, r = end arc radius
I-beam (kg/m) W= 0.00785 ×[hd+2t (b – d )+0.615 (R2 – r 2 )] h= high, b= leg length, d= waist thickness, t=average leg thickness, R= inner arc radius, r=end arc radius
Steel pipe (including seamless steel pipe and welded steel pipe (kg/m) W= 0.02466 × S (D – S), D = outer diameter, S = wall thickness.we are steel structure house manufacturer and provide steel structure house,we can guarantee quality.
Mainly have the following characteristics:
1)Adopt high-efficiency lightweight thin-walled profiles, light weight, high strength and small footprint.
2)The structure of the accessories is automatic, continuous and high-precision production. The product specifications are serialized, finalized and matched. Each part is dimensionally accurate.
3)Structural design, detailed design, computer simulation installation, factory manufacturing, site installation, etc. are synchronized in a short time difference.
4)Basic dry work does not have wet work, and interior decoration is easy to be in place at one time. Lightweight steel is galvanized and coated with a beautiful appearance and anti-corrosion, which helps to reduce the cost of enclosure and decoration.
5)It is convenient to enlarge the column spacing and provide more separation space, which can reduce the height of the floor and increase the building area (the utility space can reach 92%). The advantages in layering, transformation and reinforcement are obvious.we are steel structure house manufacturer and provide steel structure house,we can guarantee quality.
