Processing type: high gloss surface processing;
Status characteristics: smooth, high reflection;
Main content: Grinded from a good base surface, but the surface wear marks can not be eliminated. This surface is mainly suitable for fasteners for exterior decoration of buildings requiring high gloss.
2# surface (8K surface):
Processing type: mirror processing;
Status features: no direction texture, high reflection, clear image;
Main content: The surface is polished with a progressively refined abrasive and rubbed with very fine steel balls. The surface does not leave any traces of rubbing. This product is used for mirror or template connection.
Processing type: cold work hardening treatment;
Status characteristics: vary according to the material and the amount of cold work;
Main content: sufficient cold work hardening treatment for annealing dephosphorization or bright annealing steel, greatly improving the strength level.
4#HL surface (brushed surface, hairline surface):
Processing type: cold rolling, pickling, leveling, grinding;
State characteristics: continuous striated;
Main content: Polishing with a suitable particle size of abrasive material to make the surface continuous.
