Product Description

JISG 3302 cold rolled hot dipped galvanized iron steel coil

Product Description
Hot-Dip Galvanizing is a protection method for steel workpieces against atmospheric corrosion and widely used in metal structure facilities. Galvanized steel coils are made of full hard steel coils through UEC hot dip galvanizing process. After pretreatment and annealing treatment, the dedusted steel material are submerged into melted zinc solution which is about 500°C hot to attach zinc coating on the steel material as corrosion protection. Then after finishing and pulling-straightening treatment, the galvanized steel coils or sheets are finally completed.

Packaging & Shipping

Standard packing to export 4 eye bands and 3 circumferential bands in steel, galvanized metal fluted rings on inner and outer edges, galvanized metal & waterproof paper wall protection disk, galvanized metal & waterproof paper around circumfer.

Each bare coil to be securely tied with two bands through the eye of coil (or not) and one circumferential, the contact points of these bands on the coil edge to be protect with edge protectors. Coil then to be properly wrapped with water proof /resistant paper, it then to be properly and completely metal wrapped. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance, and two-four such bands securely tied around belly of coil at about equal distance.

FAQ

1.What's your MOQ?
25MT, it is for one container.
2.Do you have QC teams?
Yeah, sure, our QC team is very important, they will keep the quality control for our products.
3. What's your normal delivery time?
Our delivery time about 10-20days for standard sizes, if you have other requirements like hardness and width ,it is about 20-40days. But don't worry ,we also try our best for the delivery time ,because time longer and our cost is higher.
4.Are the products tested before shipping?
Yes, all of our PPGI and GI was qualified before shipping. We test every batch every day

Q:How are steel coils used in the production of shelving units?: Steel coils are used in the production of shelving units by being cut and formed into various components, such as brackets and supports. These components are then assembled and welded together to create the frame and structure of the shelving unit. The steel coils provide strength and durability to the shelving units, ensuring they can withstand heavy loads and provide long-lasting storage solutions.

Q:What is the minimum temperature that steel coils can withstand?: The minimum temperature that steel coils can withstand depends on the specific grade of steel and its intended application. However, in general, most steel coils can withstand temperatures as low as -40°C (-40°F) without significant damage or structural failure.

Q:What are the different thickness tolerances for steel coils?: The different thickness tolerances for steel coils can vary depending on the specific grade and type of steel being used, as well as the industry standards and customer requirements. However, common thickness tolerances for steel coils typically range from +/- 0.005 inches to +/- 0.020 inches, with tighter tolerances available for certain applications.

Q:What are the different types of corrosion protection methods used for steel coils?: There are several types of corrosion protection methods used for steel coils, including: 1. Coating: Applying a protective layer of paint or coating, such as epoxy or zinc, on the surface of the steel coil to prevent direct contact with moisture and corrosive substances. 2. Galvanization: Immersing the steel coil in a bath of molten zinc to create a protective zinc coating, which acts as a sacrificial layer that corrodes first before the steel. 3. VCI (Volatile Corrosion Inhibitors): Using volatile chemicals that release protective vapors, which form a thin layer on the steel coil's surface, inhibiting corrosion by blocking moisture and oxygen. 4. Passivation: Treating the steel coil with chemicals like nitric acid to remove impurities, creating a passive oxide layer that protects against corrosion. 5. Cathodic Protection: Connecting the steel coil to a sacrificial anode (usually made of zinc or magnesium) or using impressed current to provide a flow of electrons, which prevents corrosion by making the steel coil the cathode in an electrochemical cell. 6. Environmental Control: Maintaining controlled temperature, humidity, and atmospheric conditions during storage and transportation to minimize exposure to corrosive elements. These methods can be used individually or in combination, depending on the specific requirements and environmental conditions.

Q:I'm trying to put together a small structure using galvanized steel electrical conduit (3/4) and I can't seem to find a T-junction conduit coupler anywhere. I'm wondering if I could weld the tubing together, but I'm not sure if I can weld galvanized steel. Also, if I can weld them, is there any special technique that I need to use outside of regular acetelene/oxygen torch and solder?: Welding Galvanized Pipe

Q:In construction, what types of stress require steel to be placed in footings?: Steel is always added to concrete to handle local 'tension' stresses. (Sometimes to provide extra compression in 'pre-stressed' applications, but the steel is still in tension.) Steel would be added to the lower section of footings to stiffen them to 'bridge' local 'soft spots' in the substrate.

Q:(I'm not sure if steel is in fact a mineral)But I want to know if .. Last say topaz is stronger/harder then steel: Sandpaper , quartz will wear a hole in alloy steel. Just rub it. The steel that is.

Q:What are the common methods of joining steel coils?: The common methods of joining steel coils include welding, mechanical fastening (such as bolts or screws), and adhesive bonding.

Q:What temp does fire have to be to melt steel?: There are different types of steel. Melting point of steel depends upon its contents. Generally the melting point of stell is above 1500 c.

Q:How are steel coils priced and traded in the market?: Steel coils are typically priced and traded in the market based on various factors such as the current demand and supply, raw material costs, production costs, and market competition. Steel coil pricing often takes into account the specifications of the coil, including its size, thickness, width, and grade. Additionally, market dynamics, such as global economic conditions, trade policies, and currency fluctuations, can also influence steel coil pricing. Traders and buyers negotiate prices based on these factors, and the final price is determined through a combination of supply and demand dynamics and market forces.
