Excellent film adhesion

The coating layer is manufactured with fine porous surfaces so as to be high in surface vitality and be very excellent in film adhesion without phosphate treatment.

Excellent corrosion resistance

The surface layer is finer and harder than electrically galvanized steel sheets by using a hot-dip coating method so as to be excellent in white rust resistance at constant temperature and humidity as well as in red rust resistance. Especially, the adhesion with paint is good so as to be very excellent in paint corrosion resistance.

Excellent powdering resistance

This is manufactured in a short time heating and long time heat treatment method so as to be very excellent in powdering resistance.

Diverse mechanical property and high formability

The passing length of heating, crack and cooling zone of furnace before coating is made longer than the existing equipment so as to secure diverse mechanical property and high formability so that diverse desires of consumers can be satisfied.

Beautiful appearance

The flatness equal to the cold rolled steel sheet was realized by completely removing unevenness in the surface layer occurring during iron-zinc alloy using a temper rolling mill of high pressure load ratio after coating. Besides, this has no spangle and has a white gray color similar to EGI so as to be very beautiful in appearance

Corrosion resistance

The improved corrosion resistance of 55% AI-Zn alloy-coated steel coils is derived from the unique combination of the barrier protection of the aluminum and the sacrificial protection of the zinc. The formation of an insoluble aluminum oxide layer provides the barrier protection while the zinc provides a sacrificial protection at cut edges, scratches and areas of coating damage. Outdoor exposure testing of 55% AI-Zn alloy-coated steel onus has been conducted for over 20 years in various atmospheric environments. This testing also demonstrated a superior cut edge protection of 55% AI-Zn alloy-coated steel sheet than the galvanized steel sheet.

Heat resistance

Similar to the aluminum coated steel sheet that can resist high temperature oxidation, 55% AI-Zn alloy-coated steel sheet demonstrates better resistance to high temperature than the galvanized steel sheet.Benlog 55% AI-Zn alloy-coated steel sheet can be used in temperatures up to 315ºC.

Heat transmission and reflectivity

55% AI-Zn alloy-coated steel coil has a high reflectivity value making it an effective barrier against heat.

Surface Treatment:

Chromate treatment,Oiled or Anti-finger print

Surface Finished:

REGULAR SPANGLE:

Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.

MINI SPANGLE:

The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.

EXTRA SMOOTH:

The mini spangle is further skin-passed to produce the extra smooth surface

Q: Consider a steel rod of diameter 4.5 mm and length 3.3 m. If a compressive force of 4900 N is applied to each end, what is the change in the length of the rod?: You need to calculate the stress on the rod and compare this with the mechanical properties of the steel. It would help if you were given more info. You will need to know something about the steel such as the yeild stress and E, the modulus of elasticity. The value of E is about the same for a wide range of steels. So long as the applied stress is below the yield stress, the strain is all elastic and is calculated from E. The real answer is that you can not answer this question since you do not know what the temperature is. Given the applied load, the change in length will be much different at room temperature than at 1500C.

Q: What are the different types of steel coil finishing machines?: There are several different types of steel coil finishing machines, including slitting machines, cut-to-length machines, and coil coating machines. Slitting machines are used to cut steel coils into narrower strips, while cut-to-length machines are used to cut steel coils into specific lengths. Coil coating machines are used to apply a protective coating or finish to the surface of steel coils.

Q: How are steel coils used in the manufacturing of agricultural sprayers?: Steel coils are used in the manufacturing of agricultural sprayers primarily for constructing the frames, supports, and structural components of the sprayers. The high strength and durability of steel make it suitable for withstanding the harsh conditions and heavy loads associated with agricultural operations.

Q: What are the different methods of stretch leveling steel coils?: There are several methods of stretch leveling steel coils, including roller leveling, tension leveling, and temper rolling.

Q: Can steel coils be coated with RFID technology?: Yes, steel coils can be coated with RFID technology. This technology allows for tracking and identification of the steel coils, improving supply chain management and providing real-time information on their location and status.

Q: I have to explain some functions of stainless steel but after days of searching I cant find an answer. Thankyou in advance for your help :): What is the function/s of stainless steel? Stainless steels of various kinds are used in thousands of applications. The following gives a flavour of the full range: Domestic – cutlery, sinks, saucepans, washing machine drums, microwave oven liners, razor blades Architectural/Civil Engineering – cladding, handrails, door and window fittings, street furniture, structural sections, reinforcement bar, lighting columns, lintels, masonry supports Transport – exhaust systems, car trim/grilles, road tankers, ship containers, ships chemical tankers, refuse vehicles Chemical/Pharmaceutical – pressure vessels, process piping. Oil and Gas – platform accommodation, cable trays, subsea pipelines. Medical – Surgical instruments, surgical implants, MRI scanners. Food and Drink – Catering equipment, brewing, distilling, food processing. Water – Water and sewage treatment, water tubing, hot water tanks. General – springs, fasteners (bolts, nuts and washers), wire. don't forget to rate and good luck hope it helps you

Q: How are steel coils used in the construction of buildings?: Steel coils are used in the construction of buildings primarily for their strength and durability. These coils are typically formed into beams, columns, and other structural components, providing a sturdy framework. Additionally, steel coils can be shaped into sheets or plates used for roofing, walls, and flooring, offering excellent resistance to weather and fire. Overall, steel coils play a crucial role in ensuring the stability and longevity of buildings.

Q: Can steel coils be used in marine environments?: Although steel coils can be utilized in marine environments, it is crucial to take necessary precautions to avoid corrosion. Given that steel is susceptible to corrosion when exposed to moisture and saltwater, which are commonly found in marine environments, it is imperative to employ protective measures on the steel coils. One such method is treating them with protective coatings like galvanization or painting to establish a shield between the steel and the corrosive elements. Moreover, regular maintenance and inspections should be conducted to detect any signs of corrosion and promptly address them to prevent further harm. By implementing these measures, steel coils can be effectively employed in marine environments while minimizing the risk of corrosion and ensuring their durability and performance.
