1.2mm galvanized steel refers to a 1.2mm thick carbon steel sheet or coil that is coated with a protective zinc layer through a hot dip galvanizing (HDG) or electro galvanizing (EG) process. This coating prevents rust and corrosion and is ideal for outdoor and industrial applications. Wanzhi Steel, as a gold medal supplier, always provides high-quality 1.2mm galvanized steel. We accept various mechanical processing, zinc layer, length, and width can be customized, and we have a large number of common sizes in stock. You are welcome to contact us for details.
We often use Z+X to represent the zinc content. The amount of zinc coating determines the corrosion resistance of steel. The commonly used zinc content is as follows.
Z60–Z100: The zinc layer weight is between 60-100g/㎡, which is suitable for scenes with relatively low requirements for corrosion resistance. It is easy to perform forming operations such as stamping and bending.
Z120–Z180: The zinc layer weight is between 120-180g/㎡, which can provide good corrosion protection and is suitable for medium corrosion environments.
Z200–Z275: The zinc layer weight is between 200-275g/㎡, which has high corrosion resistance and can be used for a long time in relatively harsh environments.
Strength and toughness: The thickness of 1.2 mm gives moderate strength and toughness, can withstand moderate external impact, is not easy to break, and is suitable for scenes that require a certain load-bearing or deformation resistance.
Excellent corrosion resistance: The surface galvanized layer can effectively isolate air, moisture, and acid-base substances, greatly delay the rust of steel, and extend the service life.

Good processability: Its ductility ensures that it can be cold punched, rolled, bent, and other forming operations without damaging the coating. It can be used to make roof corrugated sheets, ventilation ducts, etc., and the surface zinc layer remains intact after forming.
Economical and practical: Compared with stainless steel, it has lower costs. At the same time, galvanizing reduces the frequency and cost of later maintenance, such as rust removal and painting, and the comprehensive use cost advantage is significant.
Good surface finish: The galvanized layer makes the surface relatively flat and smooth, which can be used directly or as a primer base, which is convenient for subsequent secondary treatments such as spray painting and lamination to improve appearance or functionality.
Beautiful surface: After chromate passivation, the zinc-plated layer can present white, colorful or military green appearance, with uniform color and high gloss, which improves the beauty of the product. It has both functional and decorative properties.
Strong wear resistance: The zinc layer and the steel base are metallurgically combined to form an iron-zinc alloy layer with a dense structure and strong bonding. The 1.2 mm thickness provides sufficient wear resistance margin, and the zinc layer is not easy to peel off under mechanical friction or impact.

Common Applications
Construction field
Light enclosure structure: commonly used to build light steel structure frames, wall and roof purlins, corrugated steel sheets, etc., such as industrial plants, warehouses, mobile houses, etc.
Inside and outside wall decoration: keels, door and window frames, anti-theft doors, protective window frames or panels, 1.2 mm galvanized steel can enhance the stability and sealing of the structure.
Tunnel walkway board: embossed galvanized sheet can be used for anti-slip corridor floors, with thicknesses of 1.2 mm, 1.5 mm, and 1.8 mm. The surface is sprayed with epoxy anti-rust primer and hot-dip galvanized.
Agricultural breeding
Greenhouse frame: as the bracket connector, side wall baffle, etc. of the greenhouse, it can withstand the high humidity environment in the greenhouse and support the film or sunshade net at the same time.
Aquaculture fence: fences or feed troughs can be made, and its corrosion resistance and high tensile strength can ensure the corrosion resistance of the fence.
Municipal engineering
Temporary guardrail: bridge and tunnel construction enclosures in public places such as urban roads and squares. It can prevent workers and passers-by from mistakenly entering the construction site.
Street light poles, guardrails: suitable for making municipal facilities such as street light poles, guardrails, outdoor billboards and signs.

Manufacturing
Home appliance shell: washing machine, refrigerator back panel, air conditioner outer shell, etc., use its anti-rust properties to extend the service life of the equipment.
Warehousing and logistics equipment: light shelf partitions, storage cage frame components, load-bearing capacity suitable for small and medium-sized goods storage, and moisture-resistant.
Auto parts: some car chassis protective plates and internal support parts of the car body require a certain strength and can resist corrosion from muddy water on the road.
Mechanical manufacturing: It is an important material for manufacturing mechanical equipment frames and brackets, which can provide reliable support for the equipment and ensure the stability of the equipment during operation.
Home & Protection
Stair handrails, shelves: stair handrails, shelves, bookshelves, etc. in home decoration can be used. Thanks to its smooth and beautiful surface.
Material storage and transportation, packaging: galvanized steel plates can also be used for material storage and transportation, external packaging, etc.
Protective nets and fences: protective fences and isolation fences in factories and communities.
Pipeline and ventilation system: pipe wall materials for kitchen and bathroom ventilation ducts and smoke exhaust ducts to reduce the risk of rust and blockage.

Product Type
(1) Corrugated galvanized sheet: wavy texture, enhanced rigidity. Used in roofs, wall panels, and mobile shelters. A variety of tile shapes can be customized.
(2) Perforated galvanized sheet: precision punching, light-transmitting and breathable, used for ventilation, filtration, screens, machine guards, etc.
(3) Embossed galvanized coil plate: textured surface, such as diamond and linen, non-slip and beautiful. Mostly used in elevators, subway floors, decorative panels, and high-altitude walkways.
(4) Galvanized steel coil: continuous coil, easy to automate. It can be used as a substrate to make various molded parts and stamped parts.
(5) Color-coated galvanized sheet and coil: the zinc layer is coated with an anti-corrosion organic coating to achieve colored steel, double rust protection, used in building cladding and signs. The type of paint is optional.

Manufacturing process
Cold Rolling: The steel coils are rolled to 1.2 mm thick with precise tolerances.
Cleaning and Annealing: Remove oil/oxide; anneal to restore ductility.
Galvanizing: Hot-Dip Galvanizing: Immersed in molten zinc (450°C) to form a bonding alloy layer with a thicker coating. Electrogalvanizing: The zinc layer is thinner and more uniform, suitable for springs, wires, nails, and precision parts.
Passivation and Coating: Chromating or oiling for enhanced protection and also for ease of subsequent processing.
Cutting and Finishing: Cut into sheets/coils as required; embossing or painting can be performed if special needs are required, and Wanzhi Steel supports customization of all RAL colors.
