Hot dip zinc coated steel coil/strip for sale

Product Description

Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized steel Coil is an essential fabrication component.

Hot Dip Galvanized steel produced by ZHONGYUAN,is coated with zinc using a continuous and controlled process. The tight metallurgical bond between the steel and coating takes place in a continuous galvanizing line. This process results in a material with the strength and formability of steel and with the corrosion protection provided by zinc. The zinc coating protects the base metal from external corrosive elements in two main ways, by acting as (1) a physical barrier and (2) a sacrificial anode.

What is the Lead-Safe Limit in Zinc?

The maximum safe limit for the amount of lead in zinc specified in ASTM A653/A653M is 0.009% (90 mg/kg). Exceeding this limit may have a negative impact on the product performance, such as delayed adhesion failure and spangle darkening. Further, excess levels of lead are harmful to human health, especially via the inhalation of fumes and dust generated during the welding and grinding operations performed during fabrication using galvanized steel and when this product is used in applications involving direct contact with human beings or indirect contact via the air, water, and soil, such as in storage tanks and water pipe lines. UNICOIL strictly complies with the lead-safe limit in zinc, and actually provides product with much lower values of lead (e.g., 60 mg/kg). UNICOIL uses high-purity zinc (minimum of 99%), which is procured from vendors approved by the London Metal Exchange.

What is the Mandatory Minimum Zinc Coating of Galvanized Steel?

 The mandatory Minimum zinc coating as per SASO ASTM A653M-A1-15 is 60 gsm (grams per square meter) in order to deliver the minimum expected product performance and life span. Applications that are closer to the sea, offshore, or in urban areas will require a heavier zinc coating. The thickness of the steel also significantly affects the product performance and its life span, and should be determined based on the final product end use and the site of installation.

To prevent staining during storage and in transit, the galvanized coils are lightly oiled or subjected to online chemical passivation treatment. Hot-dip coatings are specified in a wide range of coating mass categories.
