Hot galvanizing is common throughout

Classification of hot galvanizing

Hot galvanized sheet coils are produced by hot - rolled strip or cold - rolled strip. After crosscut with rectangular plate supplies for hot galvanized sheet; A hot galvanizing coil supplied in rolls

The hot-rolled galvanized sheet can be divided into hot-rolled galvanized sheet and cold-rolled hot-rolled galvanized sheet. In particular, steel construction, car production, steel warehouse production and other jobs.

They are mainly characterized by strong corrosion resistance, good appearance quality, favorable for deep processing, economic and practical, etc.

Commodity standard: fulfill company standard/national standard.

(1) hot galvanizing of baosteel

Produced by successively galvanizing cold - rolled or hot - rolled steel for general use or construction. Usual supply range of hot-dip galvanizing:

Thickness (0.3-3.5) width (800-1830) length (plate 1000-6000, coil inner diameter 610) in mm.

(2) galvanized steel

Galvanized steel is cold rolled base plate galvanizing. The brand names of galvanized steel mainly include ST01Z, ST02Z, deep drawing, ST03Z, ST04Z, and some, but few.

(3) Taiwan ye hui galvanizing

Taiwan ye hui galvanizing, can divide into cold rolled base plate galvanizing (SGCC), hot rolled base plate galvanizing (SGHC).

(4) pohang hot-dip galvanizing roll in Korea

The company is doing cold - rolled base plate galvanizing and hot - rolled base plate galvanizing two kinds. Its quality is stable and the market response is outstanding. Can completely replace the baosteel three - phase galvanized coil. Hope we do a good job of publicizing and introducing.

Use: first use request higher steel structure and replace part of baosteel phase 3 commodity.

Easy to present quality problem: white rust. Few others.

USES: widely used in cars, home appliances, computers and audio materials. Another big use is when the secondary electricity galvanization USES - guangzhou market.

Easy quality problem: uneven thickness.

(5) Indian galvanized coil

India national factory, India TATA, India SHREE, India pushan, India udon

Thickness below 0.5mm, function and appearance: small zinc flowers (national factory, India TATA), no zinc flowers (SHREE), usually non-passivating and lightly oiled. The weight is 5 tons and the galvanized coating is 120 grams on both sides.

USES: ventilation ducts and chimneys of northern shopping malls, as painted substrate.

Easy to present quality problems: white rust, roll deformation - can not be up to the machine, the impression is removed and bent (not through zhang long leveling, the appearance is not through finishing).
