Quality:Commercial , Lock Forming / Grade A,B,C,D,E / DQ,DDQ
Width:610mm ~ 1600mm

Special Feature & Strength

GI steel is characterized by“ corrosion resistance”,“ excellent workability”and “weldability”. It is produced by continuous annealing, temper rolling and post-treatment process. In addition, it can be classified according to various grades of formability.

Usage

Furniture, Office appliances, inner and outer panels of home appliances, automobile
inner plates, pipes, construction materials

Electro-Galvanized Steel

Description

EG is a kind of galvanized steel, coated with Zn by electrolytic coating method. On that account, EG is superior to the conventional galvanized steel in its paintability and anti-corrosivity after painting, because coating adherence amount is small but equal and smooth.

Specification

Typical Spec:JIS G3313
Thickness:0.4mm ~ 2.3mm
Quality:Commercial / DQ, DDQ
Width:610mm ~ 1600mm

Special Feature & Strength

EG is very widely used in home appliances, automobile and construction materials through various kinds of post-treatments. These goods take advantage of the fine appearance of elaborately plated layers and excellent workability.

Usage

Automobile inner and outer parts, Computer and office devices, Electronic products, Building materials and furniture, Home appliances.’

Non-Oriented Electrical Steel

Description

Non-oriented electrical steel features even magnetic properties in the rolling direction and in other directions. It is widely used for iron core materials of rotating machines ranging from large size power generators to small size precision electric motors. They are also desirable for iron core of small size transformers.

Specification

HGO (High permeability grain-oriented)
JIS C2553 30P105, 30P100:Core loss is under 1.05(W17/50)

Usage

CORE FOR TRANSFORMER
POLE TRANSFORMER
DISTRIBUTION TRANSFORMER
