Usage & Applications of Structure High Quality Mild Steel H Beams 

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

Packaging & Delivery of Structure High Quality Mild Steel H Beams 

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:Are all the steel girders H?
I-beam, channel steel, angle steel and so on, according to the different parts used in the project, choose different steel.
Q:What does "welding H" steel set "vertical" and "corrective processing" mean?
Since the H steel web needs to be machined is 10 thick, it can be easily welded to the submerged welding machine, so there is no need to break the seamAfter blanking, use the crane to lift the plate to the erection machine one by one, and clamp. Start the set, set the machine, adjust the position of the three plates, and fix the spot weldingNote: the assembling machine is specially used to assemble the H steel machine, three plates, processing it can clamp type H steel H steel will start the machine, by the end of the assembling machine to roll to the other end, through assembling the machine when the door frame, can be used to adjust the assembling machine accurate three plate position, is a period of adjustment of rolling.After erection, the crane is welded to the welding platform and submerged arc weldingAfter welding, lift to straightening machine for straightening and correctingNote: the straightening effect correction principle: after welding flange may be not perpendicular to the web, using roller flat. Because H type steel may also be in the length direction is not straight, also can use the pressure roller is adjusted. The general steel processing plant of the straightening machine only in H flat slab steel width flat with length up straight. Straight up the length function of flame correction, flame correction, H steel with roasted curved, roasted red with water, due to thermal expansion and contraction, H type steel straight up. But it must have some experience to master the operation.
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: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:H steel or I-beam, which bearing good?
If load-bearing, H steel is better.
Q:What is the theoretical weight of welded H - section steel 900*350*20*30?
298*149*12*16 is the welding specification, the weight is 63.4KG per meter.
Q:Hot rolled H section steel
The flange width, lateral stiffness.The bending capacity, than the beam about 5%-10%.The two flange surfaces parallel to each other makes the connection, convenient manufacture and installation.We compared with welded I-beam with low cost, high precision, small residual stress, without expensive welding and weld testing, saving the cost of steel production is about 30%.The same section under load. The structure of hot rolled H steel than the traditional steel structure weight 15%-20%.We compared with the concrete structure, the structure of hot rolled H steel can be increased by 6% of the area, and the structure to reduce weight 20% to 30%, reducing the internal force of structure design.The H type steel can be processed into T type steel honeycomb beam can be formed by the combination of all kinds of section form, design and production greatly satisfy the engineering demand.
Q:H Elastic modulus of section steel
The elastic modulus of steel is 2.1 * 10^7N/cm L.
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.
Q:What are the specifications for H steel HW, HB, HN?
HN is H steel with a flange width ratio greater than or equal to 2; used mainly for beams and I-beam purposes, equivalent to HN.
