1.copper mesh

kg=wire dia×wire dia×mesh x length x width ÷2 x 1.07

2. Stainless steel wire mesh plain weave

kg=wire dia x wire dia x mesh x length x width÷2

3. Stainless steel wire mesh dutch weave

kg= horizontal.dia x horizontal.dia x horizental mesh x length x width ÷ 4+ vertical dia x vertical dia x vertical mesh x length x width ÷ 4

4. crimped wire mesh

mesh=2.54÷(Wire dia.+Hole in mm)

kg= (wire diaxwire dia x mesh x length x width ÷ 2)x(1+ 2%~5%~9% )

5. nickel and molybdenum wire mesh

kg = wire diameter × wire diameter × mesh ÷ 2 × 1.13xlengthxwidth

6.Aluminum alloy wire mesh

kg=wire dia×wire dia×mesh x length x width÷2 x 0.33

7. hexagonal wire mesh

kg=1" x 1/2": wire dia×wire dia× 2 x length x width ÷ 8 x 3

other size:

kg=Wire dia×Wire dia×cardinal number x Length x Width÷2

cardinal number: 1/2"=2.15  1"=1.27  3/4"=1.6 5/8"=1.87  5/4"=1.09  

8. expanded mesh

kg=length/SWOx2xstrand width x thickness × 7.85

9.perforated mesh

kg=thickness × width ×length × (1-n) × 7.85,

n (opening rate) = hole area / whole area
