Specifications of Galvanized H beam

1. Invoicing on theoretical weight or actual weight as customer request

2. Length: 6m, 12m as following table

3. Sizes:Zinc Thickness :15-80μ

(1).used for the plant, high-rise building construction

(2).used for the bridge, shipment building

(3).used for lifting and transportation machinery, equipment manufacturing base building

(4).used for the support, foundation pile manufacturing

Packaging & Delivery of Galvanized H beam

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in    China, shipping marks and other information request by the customer.    

If loading by container the marking is not needed, but we will prepare it as customer request.

4.Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

5. Delivered by container or bulk vessel

Further performance and design information for galvanizing can be found in BS EN ISO 14713-1 AND BS EN ISO 14713-2. The durability performance of a galvanized coating depends solely on the corrosion rate of the environment in which it is placed. Corrosion rates for different environments can be found in BS EN ISO 14713-1 where typical corrosion rates are given with a description of the environment in which the steel would be used.

The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated.

A typical hot-dip galvanizing line operates as follows:

  • Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and paint.

  • The caustic cleaning solution is rinsed off.

  • The steel is pickled in an acidic solution to remove mill scale.

  • The pickling solution is rinsed off.

  • A flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.

  • The steel is dipped into the molten zinc bath and held there until the temperature of the steel equilibrates with that of the bath.

  • The steel is cooled in a quench tank to reduce its temperature and inhibit undesirable reactions of the newly formed coating with the atmosphere

Q:300*200h steel 7 meter span center load the most, can bearing 30 tons?
H section steel belongs to middle wing H section steel, can weigh 30 tons. 294*200*9*12 of the national standard. According to the specifications of the calculation, 10 meters span is large, or the cross section of the beam is a bit small, only the strong or the equivalent of roof purlin. Can not bear too much weight. Recommend the use of H type steel above 600*300*12*18. Below is the H type steel bearing calculation:RA=RB=P/2 Mc=Mmax=Pl/4 fc=fmax=Pl^3/48EI A= B=Pl^2/16EI symbol and theta theta P - Q - N; concentrated load, uniform load, N; R - bearing force, the direction of the action is positive, N; M - bending moment, the compression of the upper section, lower tension is positive, Nm; Q, the shear. The adjacent section of the torque in a clockwise direction is positive, N; F, deflection, downward displacement is positive, mm; angle theta, clockwise rotation as positive degrees; E - Gpa; I - elastic modulus, cross-sectional moment of inertia, m^4; L = x/. =x'/l, zeta, alpha beta gamma = a/l, =b/l, =c/l from two aspects
Q:H steel 200x300 how many tons?
In general, we use the "steel section characteristics inquiry and calculation tools" to calculate the small software to calculate the theoretical weight of welded H steel
Q:What is the length of the butt joint of H steel? What is the minimum requirement?
H type steel butt joint is not required for length, but oblique, generally 45 degrees, that is to say, not less than the length of at least H steel height.
Q:How to declare the processed H steel? What is the rate of tax refund? Urgent urgent
First of all, does your company have the right to import and export?! If you have, you can use your company to declare, if not, but also to find a business right to import and export enterprises to help you act as agent.
Q:What's the difference between hot rolled H steel and welded H? Is it the same weight?
The product has high precision and good surface quality. Because of the high precision and good surface quality of the steel plate, the accuracy of the H after welding is high and the surface quality is good. (used for welding H steel plate) the thickness deviation is generally a few hundredths of a millimeter to zero a few millimeters, and the thickness deviation of hot rolled H steel is a few tenths of mm to 1 mm, is nearly 10 times.
Q:Is the beam made of I-beam or H?
The I-shaped and H type are actually the same shape, which refers to the appearance of the formed steel beam, usually called the H type steel beam.
Q:What is the load-bearing capacity of H steel spans 6 meters and 300 * 300? How is it calculated?
According to the specifications of the calculation, 10 meters span is large, or the cross section of the beam is a bit small, only the strong or the equivalent of roof purlin.
Q:In the steel structure, the semifinished product H steel column, whether also sets the manufacture quota?
To fully grasp the list items and under the quota sub objective may not converge (including engineering calculation rules, etc.). The quota has the rule of calculation, the list has the rule of calculation, both must be consistent. For example, someone mentioned several times in front of the pipe support and wall bushing, the list should be calculated, but the indoor pipeline installation quota usually include a bracket and a casing (around by), then calculate the duplicate.
Q:H Elastic modulus of section steel
The elastic modulus of steel is 2.1 * 10^7N/cm L.
Q:H how long is the length of the steel section?
The average length is 12m!!!!!!!!But this H steel can be negotiated with manufacturers.According to the required length, but generally require a long time to go to docking.
