Manufacturing method |
Use for |
|
NO.1 |
Products surface treated with acid after hot rolling
|
Cold rolling materials, industrial tanks, and
industrial chemical devices
|
|
NO.2D |
No. 2D is a non-glossy cold-rolled product that has
undergone annealing and pickling treatment after cold
rolling
|
Petrochemical plants, automobile parts, building
materials, and pipes |
|
NO.2B |
No. 2B is the type that had skin-pass (temper-rolling)
performed on No.2D. It has better gloss and surface flatness
compared to No.2D. It is the standard surface class with
improved mechanical properties
|
Applicable for almost all uses
|
| NO3 |
No. 3 is polished with 100~120 mesh abrasive
|
Building exterior and interior, casings for
various kinds of home appliances, and kitchen
installations |
| NO4 |
No. 4 is polished with 150~180 mesh abrasive. Compared to
No.3, this product has a finer abrasion condition. Its
surface is an attractive silvery-white
|
Bathtubs, building exterior and interior,and
food industry |
|
NO.6 |
Produced using rotating cloth mops (Tampico fibre, muslin or
linen) which are loaded with abrasive paste.
The finish depends on how fine and abrasive is used, the
uniformity and finish of the original surface
|
Tank for industry, automobile parts, building
materials and pipes |
|
NO.7 |
A buffed finish having a high degree of reflectiveness
|
Tank for industry, automobile parts, building
materials and pipes
|
|
NO.8 |
produced in an equivalent manner to a No. 7 Finish, the
final operations being done with extremely fine buffing
compounds
|
Tank for industry, automobile parts, building
materials and pipes |
| BA |
BA is bright and highly reflective surface produced by
bright annealing after cold rolling
|
home appliances, small-sized mirrors,
kitchenware, building materials and others that
require reflective properties
|
|
HL (HAIR LINE) |
HL is a type of surface with continuous striped pattern
acquired by polishing the surface with No.4 abrasive
|
widely used for building exterior and interior.
HL is also used in sashes and doors
|
|
L-HL (LIGHT HAIR LINE) |
Surface made by polishing the surface of No. 4 products so
that ground, consecutive pattern can be seen. Surface is
softer and more graceful than HL
|
Color etching |
| SM
(SUPER MIRROR) |
Much higher degree of gloss surface in proportion to glass
mirror
|
home appliances, small-sized mirrors,
kitchenware, building materials and others that
require reflective properties |
| DULL |
Dull surface is matte finish produced by reducing gloss from
No.2B and creating roughness on the surface
|
widely used in building exterior and interior,
roofing and elevators that require reduced light
reflection |
