Circular hole mesh is a type of perforated mesh series, which is mainly named after the round holes punched in the plate.
Circular hole mesh is usually made of galvanized steel plate, stainless steel plate, copper plate, aluminum plate, nickel plate and alloy plate, which is punched by punching machine and die.
According to the different raw materials, it can be divided into
Galvanized steel plate circular mesh, stainless steel plate circular mesh, copper plate circular mesh, aluminum plate circular mesh, nickel plate circular mesh, etc. The product has the characteristics of beautiful appearance, strong integrity, uniform mesh, smooth mesh surface, easy processing and low cost.
Perforated mesh is usually used in the production of speakers for electrical products, as well as protective covers and ventilation hoods for the protection of small equipment, original noise reduction systems, filter elements for filtration in protective covers and furniture, and booth production and decoration.

Characteristic machining technology
1D -- The surface has discontinuous granular shape, also known as fog surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B -- Silver white with better gloss and flatness than a 2D surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
Ba - Excellent surface gloss, high reflectivity, like a mirror surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
No.3 -- Good gloss, coarse grain surface.
Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).
No.4 -- Good gloss, fine lines on the surface.
Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
HL -- Silver grey with hair streaks.
Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.
MIRRO -- Specular.
Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
