Hot Dip Galvanized Sheet

Hot dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot galvanizing is to pickle the steel and iron parts first. In order to remove the iron oxide on the surface of the steel and iron parts, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Prepainted Galvanized Steel Sheet

When steel components are used to make more complex finished products, they can be galvanized before the product is assembled. This is called pre-galvanizing, or "pre-galvanizing". It may also be referred to as "in-line", "continuous" or "rolled" galvanizing. Essentially, steel components (such as sheets or wires) are galvanized using an automated process before they are cut to size.

DX51D / SGCC Galvanized Sheet

DX51D (European Standard EN 10346) and SGCC (Japanese Standard JIS G3302) are two widely used international standards that specify commercial-grade hot-dip galvanized steel sheets. This product is manufactured by processing a low-carbon steel substrate through a continuous hot-dip galvanizing process, resulting in a steel product coated with a pure zinc layer. It is primarily intended for forming applications rather than structural load-bearing purposes.

DX51D Z150 Galvanized Sheet

The Z150 in the DX51D Z150 galvanized steel coil is the actual coating name. The manufacturer describes the DX51D Z150 material as a mild steel galvanized layer for steel products. Specifically, DX51D is a steel grade characterized by its cold-formed bending and profiling qualities. The steel grade corresponds to steel grade 1.0917

DX52D/SGCD1 Galvanized Sheet

DX52D (European Standard EN 10346) and SGCD1 (Japanese Standard JIS G3302) are specifications for hot-dip galvanized steel sheets designed for deep drawing and complex forming applications. They feature a low-carbon steel substrate with enhanced formability, coated with a pure zinc layer for corrosion protection. The "D" in both designations signifies their primary use for forming (Drawing).

DX53D/ SGCD2/SGCD3 Galvanized Sheet

The material of DX53D galvanized sheet is a cold-rolled steel sheet with a hot-dip zinc coating. The substrate is a low-carbon steel with excellent deep-drawing and forming properties, while the zinc coating provides corrosion resistance through sacrificial protection. It is produced through a continuous hot-dip galvanizing process, where the cleaned steel strip is immersed in molten zinc and then cooled to form a metallurgically bonded zinc‑iron alloy layer. The product is widely used in automotive panels, home appliance housings, and other deep‑drawn or severely formed parts that require both high formability and good corrosion resistance.

Z275 Galvanized Sheet

The galvanized steel coil Z275 is a double-sided galvanized carbon steel sheet. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc. This continuous hot-dip plating or also known as electro-galvanizing is the main process that these carbon steel sheets must go through to produce coils and galvanized sheets. The process consists of applying zinc by electrolytic treatment. After the sheet is subjected to this treatment, a layer of zinc is adhered to the base metal through the iron and zinc bonding layer.

Z120 Galvanized Sheet

Z120 is the coating name, which means that the coating thickness on both sides is approximately 120g/㎡ or 36g/㎡ (three-point test) and 90g/㎡ (single-point test). Z120 grade galvanized steel coil is coated with zinc to make it more durable. The working principle of the process is to immerse the coiled steel plate in a galvanizing tank filled with molten zinc. Through the continuous galvanizing process of the thin steel sheet, the galvanized coil is obtained. This type of steel has better formability and good paint adhesion in commercial or architectural use. Another method of producing galvanized steel sheet is through a hot-dip plating process. In this method, it is essential that the steel sheet is heat-treated at 500°C immediately after the exit of the can to form the alloy film coating.

G40 Galvanized Sheet

Galvanized steel coils are covered with a zinc coating to provide corrosion resistance. G40 galvanized steel coil is a galvanized layer name or A653 standard specification specified in the hot-dip coating process galvanized (galvanized) or zinc-iron alloy (galvanized) steel sheet requirements. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.

G60 Galvanized Sheet

G60 is the coating grade of steel sheet after continuous hot dip plating process. G represents the "galvanized" or galvanized layer of the product. The number 60 refers to the thickness of the zinc around the steel sheet or the thickness of the entire double-sided coating. To get the amount of galvanizing on one side, you need to divide this number by two. Galvanized steel sheet G60 is coated with molten zinc. After the continuous coating process at a speed of 600 feet per minute, the excess zinc on the steel plate is removed by high-pressure air. This is in order to produce the desired coating thickness. After cooling, the sheet is rolled into a roll, ready for manufacturing.

G90 Galvanized Sheet

G90 refers to the coating type and coating weight on the steel coil or steel plate. "G" means that the coating is galvanized, that is, galvanized. Meanwhile, the number "90" represents the weight of zinc on the steel. G90 galvanized steel coil is hot-dip galvanized cold-rolled steel sheet to improve durability.

Galvalume Steel Corrugated Roof Sheet

A Galvalume steel corrugated roof sheet is a high-performance building material manufactured from Galvalume-coated steel coil. The core of this product is a hot-dip coating composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, which metallurgically bonds to the steel substrate. This unique alloy coating synergistically combines the barrier protection of aluminum with the sacrificial anode protection of zinc, resulting in a roofing material with exceptional durability, longevity, and aesthetics, suitable for a wide range of architectural and industrial applications, including extreme environments.
