Products Description
Galvanized steel plate is made by immersing a thin steel plate in a molten zinc bath, and a layer of zinc thin steel plate is attached to the surface. Galvanizing is one of the most effective and economical methods of protecting bare steel from corrosive environments. Zinc not only acts as a barrier between steel and the environment, but it also sacrifices itself to protect the steel plate underneath.

Galvanized zinc flower type:
The American ASTM A653 standard galvanized steel plate and coils have two different flower types
Ordinary zinc flowers are galvanized, galvanized 30g to 275g (G90). Thickness from 0.15mm to 2.0mm. Ordinary zinc flowers can be used for damp -heat outdoor places. For example, fences, roofs, garage doors, etc.
Galvanized zinc flower, such a shiny GI, 30g galvanized to 2755g (G90). The thickness ranges from 0.12mm to 0.25mm. It can also be used outdoors. Mainly exported to Southeast Asia and Africa. It is cheaper than GI with conventional sequins. This product can be processed later, such as processing into stone coating tiles.
Galvanized metal plate inspection：
1. Size and shape measurement items: allowable deviation of thickness, width, length, unevenness, out of square degree and sickle bend.
2. Chemical composition test items: carbon content, sulfur content, manganese content, silicon content, phosphorus content, titanium content, aluminum content, niobium content, vanadium content, etc.
3. Physical performance test items: yield strength, tensile strength, elongation after breaking, R value, N value, tensile strain mark, baking hardening value, coating adhesion, coating weight, coating surface structure, surface quality, adhesion and corrosion resistance.
4. Environmental performance evaluation test items: lead content, content, cadmium content and hexavalent chromium content.
5. Galvanized sheet brand identification
Application areas of gi steel sheets:
The hot-dip galvanizing process provides much-needed corrosion control in many applications and industries, including energy, utilities, automotive, agriculture, construction, HVAC, transportation, chemical processing, telecommunications, outdoor recreation and more. With low initial cost, low maintenance costs and a long service life, galvanizing is a versatile and economical method of protecting steel substrates. In addition, the galvanized layer has excellent corrosion and rust resistance, UV protection and excellent non-flaking properties.
