Non-standard handwashing countertop stone window sill stone measurement method
ONE
Non-standard washbasin area = actual projection area of the countertop + area of retaining stone + skirt area
1. Non-standard under bench basin washbasin area
Table stone area = A*B+(A+B)*H+(D1+D2)*C
2. Non-standard table basin washing table area
Table stone area = A*B+(A+B)*H+(D1+D2)*C
3. “L” type non-standard washing station area
Table stone area = A1*B+A2*B2+(A1+B1+A2)*H+(DI+D2)*C
TWO
Non-standard window sill stone area = actual projection area of table stone + lower water edge area
Grinding edge length = lower retaining edge length
1. “One” shaped window sill stone area
Window sill stone area = A*C+D*E*2+B*H
Edging length = B
2. “L” shaped window sill stone area
Window sill stone area = A*B1+D*B2+F*G*2+(C+E)*H
Grinding length = C+E
3. “Bagua” type window sill stone area
Window sill stone area = (A+E)*D/2+(B+F)*D/2+(C+G)*D/2+(E+F+G)*H
Edged length = E+F+G
THREE
Non-standard threshold stone area = actual projection area of threshold stone + thickened edge area
1. No thickened edge sill stone area
Sill stone area = A*B
2. There is a thickened edge sill stone area
Sillstone area = A*B+A*C
