How much is a ton of I-beam now

The price of I-beam is around 4000 yuan/ton. If accurate price is needed, it is also necessary to provide accurate specifications, models and product weight requirements. I-beams have different specifications and models, different uses, and of course different prices. I-beams with the same specifications and different weights will have different prices.

1. The price of I-beam is slightly higher than that of raw materials. I-beams are made of Q345B, and commonly used raw materials are Q235 and Q345. The raw material of manganese steel is Q345B. Q345B I-beam is manganese I-beam. Manganese steel is a kind of high strength steel. It is mainly used to withstand severe working conditions such as impact, rubbing and material wear. The main damage mode is wear, and some parts have cracks and deformation. The wear of I-beams can be divided into three types: the impact wear of metal components when they contact and move; Abrasive wear caused by the impact of other metals or nonmetallic materials on the metal surface and erosion wear caused by the contact between moving gas or liquid and metal.

2. When buying I-beams, besides the price of I-beams, we also need to consider the quality of I-beams. Some customers will have different weighing weights after receiving the goods, and the appearance of I-beams will have common defects. When I-beams are delivered by manufacturers at low prices, the following problems will occur: scars: metal sheets with scars on the surface of I-beams. Its size, depth and shape are very irregular, often in the form of nails, fish scales, blocks and tongues, irregularly distributed on the surface of steel, and there are often nonmetallic inclusions under the scars. Reason: Because the billet is not cleaned, the original scar still exists after rolling.

3. Delamination: The defect on the cutting surface of I-beam saw is black line or black belt, which is seriously divided into two or more layers, accompanied by inclusions. Reason:

(1) is mainly due to shrinkage cavity of killed steel or gasbag of boiling steel.

(2) The bubbles under the billet are loose and there are no impurities during rolling, which will also cause delamination.

(3) The chemical composition of billet is seriously segregated, and delamination is formed when it is rolled thin. The reason for the low price of I-beam must be the product. Don't ignore the product for the price.

4. I-beam, also known as universal beam, is a long steel with I-section. I-beams are divided into hot rolled I-beams and light I-beams. This is an I-beam. I-beams are mainly divided into ordinary I-beams, light I-beams and low-alloy light I-beams.
