Usage & Applications of Hot Rolled Structural Steel H Beam

Commercial building structure ;Pre-engineered buildings; Machinery support structure; Prefabricated structure; Medium scale bridges; Ship-building structure. etc.

Packaging & Delivery of Hot Rolled Structural Steel 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

Q:What is the weight per metre of 250x250x9x14h steel, please? Do you have any relevant information? Thank you
The main material of H steel is Q235B, SM490, SS400, Q235B, Q345, Q345B and so on.
Q:Method for calculating weight of H steel
Sectional area=(H+2T =(TW)2bt 580×2×14)+2×280×12×14 = 144.64cm2
Q:How to distinguish between narrow flange and wide flange H section steel
I as the name suggests, is a kind of I-shaped section steel flange on the inner surface of slope is generally 1:6, the flange and the thickness of thin, resulting in two main characteristics of I-beam section plane is huge, it is difficult to play the strength of steel in the application, as the first picture shows. Although there has been a thicker I-beam in the I-beam market, the structure of the I-beam has determined its torsional properties.
Q:What's the difference between hot rolled H steel and welded H? Is it the same weight?
Stable performance and good internal organization. Due to continuous casting from smelting to rolling, steel production than hot-rolled H steel process requirements, equipment capacity, control level, detection means is high, so the welding of H steel internal organization, chemical composition, various properties (mechanical properties, process performance indicators are reliable and stable etc.).
Q:How can the steel posts of different types of H steel be butted?
The same type of H steel, steel column butt joint, bolted or welded joint or all welded joints.
Q:H steel column calculationHow do you calculate the amount? And what are the steps and formulas for this calculation?
H steel is welded; HWHMHN is the hot rolled HW H steel is the height and width of flange is basically the same; mainly used for reinforced concrete frame column steel column, also known as rigid steel column; in steel structure is mainly used for HM H type steel column and steel I-beam flange height of airfoil is a variable cross-section on web portion thick and thin outer flange; H steel is uniform HWHMHNH is known as H steel
Q:Can the section steel butt joint on the end?
If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.
Q:In the steel structure, the semifinished product H steel column, whether also sets the manufacture quota?
The cost budget is easy to miss 100 items. 1, in the flat roof insulation roof discharge hole2 embedded iron pieces in the stair railing3 scaffold for paint and coating construction4 precast slab beam concrete: plate, beam head concrete, transportation, installation5 bored pile: drilled into the depth of rock (the municipal and highway quota projects contain a great gap in content)6, the installation of indoor plumbing is easy to miss
Q:H steel or I-beam, which bearing good?
If load-bearing, H steel is better.
Q:What's the quota for finished H - shaped steel sleeve?
In the installation of H steel, in addition to painting, that is, rust, units are 10m2, there is no security item. Landlord can not really apply: Civil Engineering - metal structural engineering - steel structure - steel wall (or other), and this is my personal opinion, for reference only.
