Product Description:

1.Structure of Hot-Dip Galvanized Steel Sheet Description

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.

2.Main Features of the Hot-Dip Galvanized Steel Sheet

• Excellent process capability

• Smooth and flat surface

• Workability, durability 

• Excellent anticorrosive property

• High strength

• Good formability

• Good visual effect

  • D500N12 is deformed bar, 500 MPa strength, normal ductility and 12 mm nominal diameter - also known as "N12"

  • R250N20 is round bar, 250 MPa strength, normal ductility and 20 mm nominal diameter - also known as "R20"

Bars are typically abbreviated to simply 'N' (hot-rolled deformed bar), 'R' (hot-rolled round bar), 'RW' (cold-drawn ribbed wire) or 'W' (cold-drawn round wire), as the yield strength and ductility class can be implied from the shape. For example, all commercially available wire has a yield strength of 500 MPa and low ductility, while round bars are 250 MPa and normal ductility.

5.FAQ of Hot-Dip Galvanized Steel Sheet 

We have organized several common questions for our clientsmay help you sincerely: 

1.How about your company

A world class manufacturer & supplier of castings forging in carbon steel and alloy steelis one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

2.How to guarantee the quality of the products

We have established the international advanced quality management systemevery link from raw material to final product we have strict quality testWe resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q:What about the size of a large tractor engine
A large tractor has six cylinders with four cylinders, so the displacement is about the size
Q:Agricultural tractor four-wheel drive than the two drive what is the benefit
The front wheel can also be driven, the obvious difference between the front tread pattern and the rear tread pattern is the same, and the front tires are larger than the front wheels of the two drives.
Q:What is the reason for the abrasion of a tractor
Front wheel toe-in improper adjustment, the main reason is that the hollow shaft and shaft bushing wear before the clearance is too large, hollow shaft and bushing forging is easy to wear. When l this material set of wear l, big intervals between the front wheel toe-in value change, accelerate the wear of front wheel.
Q:Walking tractor shake, how to do?
Directly see the car, but according to what you say I think 90 percent is to hold the tile, and the situation is very bad, ordinary tile for tile on OK, you not only have to change the crankshaft have to change, seven
Q:What skills do you have for a tractor?
Tractors are also called "upgrading" games Each 5, 10 and K in the upgrade game will be a card, 5 for 5, 10 for 10, and K for 10, and two for 200. In the game, each party should try to catch the CARDS. The card that is clasp in the bottom card, if the bookmaker is buckled at the bottom of the calculation, double the calculation.

Ordinary we can buy diesel are: 0 #, - 10 #, - 15 #, - 20 #, - 30 #, there are -35 # military.
Q:Why should the tractor use diesel?
The same displacement and fuel consumption, diesel engine effort than gasoline engine four times.
Q:Do you want these tractors to be tractors?
On the deputy 2 and on the main 1 is the tractor, the main 2 and the pair 2 is the tractor, the main 1 and the pair 2 is the tractor, the main 2 and the king is the tractor, the above are tractors, adjacent two

GB / T 8421-2000 Laboratory measurement and limits for transmission vibration of agricultural wheeled tractors
Q:How is the music tractor?
Broken than the car, who to buy who regret, said aftermarket is good, not a pack of three, for parts to spend money, big trouble did not out, little trouble constantly, do not buy this broken car.
