Hot RolleD Steel I Beam

Applications of GB Standard Hot Rolled Steel I Beams Q235, Q345

Hot Rolled Steel I Beam is widely used in various building structures and engineering structures such as roof beams, bridges, transmission towers, hoisting machinery and transport machinery, ships, industrial furnaces, reaction tower, container frame and warehouse etc.

Package & Delivery Terms of GB Standard Hot Rolled Steel I Beams Q235, Q345

1. Package: All the hot rolled steel I beam will be tired by wire rod in bundles

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. Shipment: In containers or in bulk cargo


Hot Rolled Steel I Beam

6. Delivery time: All the hot rolled steel I Beam will be at the port of the shipment within 45 days after receiving the L/C at sight ot the advance pyment by T/T

7. Payment: L/C at sight; 30% advance payment before production, 70% before shipment by T/T, etc.

Q:No. 20 I-beam, span 9 meters, can support the concrete roof?
No. 20 I-beam 9 meters span, even without bearing, the naked eye can see the middle bend (waist down).
Q:How heavy is the steel rope for lifting I-beam?
The cause of the failure of wire rope is fretting fatigue, manganese phosphate and zinc manganese phosphating are bonderizing, can improve the wear resistance and corrosion resistance on the surface of the wire, not easy to wear and easy corrosion of the fatigue life is three times of smooth wire rope, the highest test has reached four times, can be verified by the fatigue test, far more than the imported wire rope, the use of lower cost, higher cost, phosphating coating steel wire rope is the patented technology, many enterprises have already authorized for production, for reference only.
Q:What's the difference between 16# I-beam and 16A I-beam?
No. 16 means waist high 16cm, if the waist thickness has different sizes, then need to add a, B, C to distinguish, but the standard specification and exterior did not see 16A this model, more than 20 of the A, B or C model difference
Q:What is the length of common I-beam?
The length of the steel bar is generally 9m and 12m; the length of the I-beam and H section steel is generally 12m; the factory length of the angle steel is generally 6 meters; the common length of the channel steel is 6 meters, /8 meters and /9 meters.
Q:What are the meanings of I-beam BH300 x 200 x 6 x 8 in steel structures?
BH is welded to H type steel, not hot-rolled steel H from steel mill. Generally processed by the factory with three pieces of steel welded. BH300*200*6*8, i.e., high 300mm* wide 200mm* web 6mm* flange 8mm.
Q:In the welding of steel structure, the welding between I-beam and stiffener needs three sides to be welded
When the I-beam is the main load, it is recommended that all welds be fully welded
Q:Does the surrounding rock of tunnel V first load I-beam or first lead bolt?
In the actual construction, it is difficult to construct the I-shaped steel frame first, and then the construction of the leading small pipe is difficult, which leads to the increase of the outer inclined angle of the leading small pipe, and can not meet the requirements of the external inclination angle in the design or technical guidelines. The problem belongs to design defects and is difficult to solve.
Q:How can I distinguish between rolled H steel and welded I-beam?
The connecting parts of the wing plate and the rib plate of the hot rolled steel are concave and smooth in transition and uniformly uniform in longitudinal length.
Q:What span is the maximum span for I-beam?
I-beam is also called steel girder (English name Universal Beam). It is a strip of steel with an I-shaped section. I-beam is divided into ordinary I-beam and light I-beam, H steel three. It is a section steel whose shape is trough.
Q:What is the free length of the compression flange?
For beams without lateral support points in the midspan, L1 is the span; for the beams with lateral supporting points in the midspan, L1 is the distance between the lateral supporting points of the compression flange (the lateral support of the beam is considered as lateral support).
