Angle specifications indicated by the sides and edge thickness dimensions. Current domestic angle specification 2-20 to centimeter side angle for the number of number of channels, the same number of different angles often 2-7 edge thickness. Imported angle indicates the physical size and edge thickness on both sides and indicate the relevant standards. General side 12.5cm above for large angle, for the medium angle between 12.5cm-5cm side length 5cm or less for small angles.
