The minimum weight of zinc coating mentioned above indicates the minimum weight of zinc coating on both sides of sheets or coils. This expresses the average measured weight of zinc coating of triple spot test pieces cut from the test sheets.
Pre-painted Galvanized Steel
Resistance to acid rain: Coating protection mechanism: it is very easy to form acid rain in the high level of industrial emissions or pollutants environment. Acidic penetration is formed in the surface of pre-painted steel, and accelerates the corrosion, forming blistering, peeling and so on.
Resistance ultraviolet rays: Coating protecting mechanism: pre-painted sheet in ultraviolet or strong sunlight conditions, the coating will exhibit chalking degeneration, manifested as discoloration and loss of gloss, lose paint quickly.
Resistance to humid heat: Coating protecting mechanism: in hot and humid environments, high osmotic pressure of water vapor accelerates penetration, forming the degeneration of painting film, then the corrosion of the substrate, with the phenomenon of bubbles and peeling.
Resistance to low temperature: Coating protecting mechanisms: most of the paint can keep stable processing performance above 0°degree, but at alpine region, the temperature will be below 20°-40°degrees, normal paint will become brittle bend cracking, or even lose paint, thus protection function is lost totally.

TFS
TFS (Tin Free Steel, also known as ECCS, Electro-Chromium-Coated-Steel).
Low carbon steel covered with chromium with a layer between them of steel-chromium alloy. Its price is slightly cheaper than tinplate. It is mainly used for producing can lids or ends, two pieces cans (drawn cans) and crown caps.
Chromium provides very good lacquer adherence. It is not apt for welding.
This material can be supplied in sheets or coils. In the case of sheets, we deliver the material lacquered and printed, as well as with straight or scroll cut.
Even though the minimum thickness can be of 0.10mm, the standard range is between 0.13 and 0.50mm.
Basic Uses of tinplate
Food cans: Standard ends, easy-open ends, twist-off caps, crown taps, round or rectangular welded bodies, drawn bodies, and deep drown bodies (DWI).
General line cans: Aerosol, ends, tops, rings, welded round or rectangular bodies, welded and expanded bodies, drawn bodies, decorative cans.
Other applications: Deep drawn and moderate conformation.
