Products DescriptionGalvanized steel sheet also named GC Sheets,Website:, are to prevent corrosion of the steel surface to extend its service life, the steel surface
coated with a layer of metal zinc. Because zinc can form a good corrosion resistant film on the surface in corrosive environment. It not only protects the zinc layer itself, but also protects the steel base. So galvanization ??is the biggest advantage of good corrosion resistance, painting, decorative
and good formability. Galvanized steel sheet are mainly used in automobile, home appliances, architecture, machinery, electronics, light
industry and other industries.There are three kinds: ??electro-galvanized steel , hot dipped galvanized steel and coating galvanized steel.Galvanized steel sheet can be divided into two types: intra line annealing and off-line annealing, namely,
the protection gas method and flux method.Professional production and high technology can avoid effectively zinc layer shedding, scratching, passivating spots, zinc particles, thick edges, gas knife scratches, air knife scratches, exposed steel, inclusions, mechanical damage,
steel base performance, wave edge, ladle curve, size incompatibility, imprint, incompatibility of zinc layer thickness, roll print, etc.The main reasons for the loss of zinc layer of galvanized steel corrugated sheets: surface oxidation, silicon compound, NOF section
oxidation atmosphere, too high dew point of protecting gas, unreasonable air combustion ratio, low hydrogen flow rate, oxygen infiltration of furnace, low temperature of strip, low NOF Duan Luwen, low oil evaporation, low
content of aluminum in zinc pot, speed of unit too fast, reduction The time of residence in zinc liquid is too short, and the thickness of coating is too thick.Supereal Enterprise Limited absorbs advanced production equipment, employs experienced engineers and professional and responsible sales team to guarantee avoidance the loss of zinc layer.There are four kinds of spangle on the surface: big spangle(its crystal core diameter is no less than 0.2 mm),regular spangle, small spangle and non
spangle. Usually big spangle and regular spangle galvanized steel sheet are used in construction and roofing.Products DetailsCommodityGalvanized Steel SheetsStandardB/T1839-2003,??JIS??G3302,ASTM??A653,EN10143GradeSGCC,DC51D,DX51D,DX52D,,SGCD,Q195,Q235,SGHC,DX54D,??S350??GD,S450??GD,S550??GDTypesCommercial??/??Drawing??/??Deep??Drawing??/??Structural??qualityWidth600-1250 mmThickness0.12-0.8 mmZinc??coatingZ40-150g/m2Surface??treatmentchromed??/??skinpass/??oiled/slightly??oiled/??dry/??anti- fingerprintSpanglezero??spangle??/??minimized??spangle??/??regular??spangle/??large??spangleLength1830 mm, 2000 mm, 2440 mm, 3048 mm, 4200 mmBundle??Weight2.5-3 MTPackageStandard??seaworthy??export??packageApplicationRoofing??and??walling,??curved??profiles,??corrugated??sheetsPayment??terms30% TT??in??advance ??and ??70%??balance against copyof ?? ??BL??or??30%??deposit(T/T)??irrevocable??70%L/C??at??sightDelivery??timeup??to??total??quantity??or??as??client??requirement,usually??after??recepit??of??30%??TTTemper??Full??hard,??half??hard,??soft??Remarksinsurance??is??all??risksMTC????will??be??handed??on??with??shipping??documentsWe??can??supply??certificate??SGS,BV??etc.Packaging & Transport & LoadingGalvanized Steel Sheet in Sierra LeoneGalvanized steel sheet are very popular in Africa .Size of 0.12 * 665 * 1830 mm is the best selling size in West Africa, especially in Sierra Leone, Gambia, Kenya, and Nigeria.Because of the different ethnic cultures, different regions
and climate, there are different residential buildings in West Africa, as if the stars scattered in the African continent, it is a wonderful spectacle. But most roofs use galvanized steel sheet as the materials because of the economic backwardness and poverty.The main discharge port in Sierra Leone is Freetown and the main destination port in Gambia is Banjul. Usually we load galvanized steel sheets in 20 feet container at Qingdao port and Tianjin port in China and it needs about 55 shipping days by MSK shipping line and CMA shipping line to destination port.
In the off season, I mean the rain season, West African customers usually reduce the importing quantity. And they will start importing steel sheet after August.Contact Us??Hawk ?? ?? ?? ??
