Stainless steel welded mesh - calculation method
Square meter weight (kg) = wire diameter × wire diameter × [25.4 ÷ (mesh size × 25.4 + wire diameter)] ÷ 2
Square meter cost price (yuan) = square meter weight × wire unit price + welding mesh fee + circulation fee
For example: the mesh size is 1/2" × 1/2", the wire diameter is 1.2mm. The square
meter cost price of stainless steel welded mesh (yuan) = 1.2 × 1.2 × [25.4 ÷ (1/2" × 25.4 + 1.2)] ÷ 2 × 30.7 + 2 yuan + 0.8 yuan = 43.18 yuan
(Note: 30.7 yuan is the price of SUS304 per kilogram at that time)

Wide-width stainless steel welded mesh - calculation method:
Weight per roll (kg) = wire diameter × wire diameter × mesh number ÷ 2 × length × width
[mesh number = 25.4 ÷ (specification + 25.4 + wire diameter)]
For example: mesh size is 1”×1”, wire diameter is 2.0mm, width is 1.5m. Cost price per square meter of stainless steel welded mesh (yuan): 2.0×2.0×[25.4÷(1"×25.4+2.0)]÷2×27.5+2.5 yuan+1.2 yuan=58.7 yuan

Large wire welded mesh - calculation method:
Weight per roll (kg) = wire diameter × wire diameter × mesh number ÷ 2 × length × width [mesh number = 25.4 ÷ (specification + 25.4 + wire diameter)]
For example: specification is 1/2'' × 1/2'' hot-dip galvanized wire mesh, 1 meter wide, 30 meters long, 19# wire low carbon steel welded mesh (19# wire 3.2 yuan/kg, Zinc 12 yuan/kg)
Weight per roll: 1.0×1.0×[25.4÷(1/2×25.4+1.0)]×1 meter×30 meters=30kg
Zinc application fee: 30kg×15%×12 yuan=67.5 yuan (15% is the zinc application index of 1/2" welding mesh)
Cost per roll: 30×3.2 yuan/kg+67.5 yuan+8 yuan+7.5 yuan+6 yuan=215 yuan/roll
Hook flower net (diamond net)--Calculation method Square meter weight (kg) = wire diameter×wire diameter×1.29÷aperture Square meter cost (yuan) = Square meter weight×wire unit price+processing fee+circulation fee
For example: 5cm×5cm hole, wire diameter is 2.3mm, square meter cost price (yuan) = 2.3×2.3×1.29÷5×3.45 yuan+0.25+0.5 yuan=5.46 yuan/m2

Grassland fence net--Calculation method
Net weight kg = wire diameter × wire diameter × 0.00617 × wire length used (m)

Calculation method of razor wire:
To produce one ton of barbed wire, 480kg of core wire and 800kg of plate are required. The price of core wire is 3700 yuan/ton and the price of plate is 6500 yuan/ton.
Cost (yuan) = 480×3.7+800×6.5+1000 (cost) = 7976 yuan/ton

Barbed wire - calculation method: sold by ton price: (12# current price 2250 yuan/ton, 14# current price 2600 yuan/ton)
cost accounting = total weight × (strand price × 70% + barbed wire price × 30%) + processing fee

Anti-theft Meige Net - Calculation method Square meter weight (kg) = wire radius × wire radius × 1.54 ÷ average aperture
For example: φ4.0mm, hole 8cm × 10cm Small flower Meige Net
per square meter weight (kg) = 4.0 × 4.0 × 1.54 ÷ 9 = 2.72kg
Square meter cost (yuan) = 2.72kg × 3.2 yuan/kg + 2.2 yuan (processing fee) + 0.7 yuan (circulation fee) = 11.2 yuan

Stainless steel crimped wire mesh - calculation method
Square meter weight (kg) = wire diameter × wire diameter × mesh number ÷ 2 × n
[Note: mesh number = 25.4 ÷ (mesh size + wire diameter)] (n is 1.13 when the wire is large or double wave ginning, and 1.1 when the wire is small) Square meter price (yuan) = square meter weight × wire price + labor time fee + circulation fee
Steel wire crimped wire mesh - calculation method 2008-5-12 Square meter weight (kg) = wire diameter × wire diameter × mesh number ÷ 2 × n [Note: mesh number = 25.4 ÷ (mesh size + wire diameter)] (n is 1.13 when the wire is large or double wave ginning, and 1.1 when the wire is small) Square meter price (yuan) = square meter weight × wire price + labor cost + circulation fee... Iron wire mesh - calculation method 2008-5-12 Square meter weight (kg) = wire diameter × wire diameter × mesh number ÷ 4.58 × n [Note: mesh number = 25.4 ÷ (mesh size + wire diameter)] (n is 1.13 when large wire is ginned or double wave ginned, and 1.1 when small wire is ginned) Square price = square meter weight × wire price + labor cost + circulation fee...

Coiled round hole mesh - calculation method
1. Punching rate calculation: n = hole area ÷ plate area × 100%
2. Round hole mesh calculation: square meter mesh weight (kg) = mesh thickness × mesh width × 1m × 7.85 (specific gravity × (1-n) square meter price (yuan) = square meter number × plate price/m2 + processing fee + circulation fee...

Plastic vinyl window screen--Calculation method
Net weight (kg) = wire diameter × wire diameter × mesh number × length × width ÷ 2 ÷ 6.78 Twisted wire net weight (kg) = (wire diameter × wire diameter × mesh number × length × width ÷ 2 ÷ 6.78) × 1.5 Cost (yuan) = net weight × wire price + labor time fee + Liu Fei net...

Dense mesh (mat-type mesh) - calculation method:
Weight per square meter (kg) = (diameter of radial wire × diameter of radial wire × number + diameter of weft wire × diameter of weft wire × number of weft meshes) ÷ 4 For example: Weight per meter of MPW280 stainless steel mesh: (0.112 × 0.112 × 71.1 + 0.08 × 0.08 × 350) ÷ 4 = 0.78kg/m2 (Note: For the corresponding diameter and weft data of MPW280, please refer to the common specifications table of dense mesh) Square meter...

Calculation method of plate mesh
1. Punching rate calculation: n = hole area ÷ plate area × 100% 2. Calculation of round hole mesh: square meter mesh weight = mesh thickness × mesh width × 1m × 7.85 (specific gravity) × (1-n) square meter price = square meter number × plate price/m² + processing fee + circulation fee...
