Galvanized Gabion basket
Gabion Basket means the provision by the machine a twisted hexagonal wire mesh surface together constitute a box-shaped components .Gabion basket at the construction site by stones fill to form a flexible ,permeable and overall structure, is mainly used in control river,protection of rock breaking,bridge protection, soil and water conservation ,road protection etc.
Zhuoda Gabion basket production quality is in full accordance with ASTM A975-97 standard and EN10223-3 standard.
Main Materials of Gabion basket
Galvanized steel wire:High quality low carbon steel wire, wire diameter is 2.0MM-4.0MM, the tensile strength of steel wire is not less than 380Mpa. Hot dipped galvanized steel wire protects the surface. The thickness of galvanized protective layer can be produced according to customers’request. The largest mass of zinc coat is 300g/m2.
Galfan steel wire is a new international materials in recent years. Corrosion resistance of zinc coat is over 3 times than the traditional coat. The steel wire diameter is up to 2.0MM-4.0MM, the tensile strength of steel wire is not less than 1380Mpa.
Galvanized steel wire after PVC coated:high low-carbon steel wire, warped PVC and PE protective layer in galvanized steel wire surface, and then woven into all kinds of Gabion box. This protective layer will increase the protection of higher pollution environment. The choice of different color is suitable to surrounding environment.
Zinc Coatings
Service Life* vs. Coating Zinc Thickness
* Service life is defined as the time to 5% rusting of the steel surface
Galvanized
A zinc coating, usually hot-dipped, in which the zinc and steel form a metallurgical bond. The thickness of a hot-dipped coating can be varied from a thin zinc/iron alloy layer to heavy applications suitable for extended outdoor exposure. In-line galvanized coatings are applied during the manufacturing process of the hollow or open section, with the cleaned steel section exiting the mill and passing into the galvanizing bath. This coating is usually measured as thickness or as coating mass in grams per square meter and ranges from a minimum of about 100 g/m2 upwards, with an average around 175 g/m2.
Electro galvanized
Also a zinc coating, but applied in a cold, electrolytic bath rather than a molten zinc bath. Traditionally the coatings are thinner than hot-dipped and not suitable for extended outdoor exposure. This process applies a layer of pure zinc that ranges from a few microns on cheap hardware components to 15 microns or more on good quality fasteners. Technical and cost issues prevent the economical plating of components with heavier coatings.
Galfan
A proprietary zinc alloy coating (5% aluminum) with improved corrosion resistance and formability compared to zinc alone. Galfan has been around since the International Lead Zinc Research Organization (ILZRO) obtained worldwide patents on this new alloy for anti-corrosion coating in 1981. It was discovered that by combining 95% zinc with nearly 5% aluminum plus specific quantities of rare earth mischmetal could be reliably used in the hot-dip coating process, and conferred substantially improved performance to the end-product.
Standard:
Wire tolerance:ASTM A641-89
Strength tensile: ASTM A641-92
Weight of galvanized wire: ASTM A-90
Zinc coated weight: ASTM A-239,ASTM B-6
Elongation: ASTM A370-92
