Carbon steel bar

Round bar :Widely used in aerospace, electric energy, oil and gas, chemical treatment, mechanical engineering, shipbuilding transportation, machinery manufacturing, electronic technology, automotive industry, environmental protection and other fields.

Die steel

Tool steel is used to manufacture cold punching die, hot forging die, die casting die and other types of steel.Mould is the main tool for manufacturing parts in the industrial sectors such as machinery manufacturing, radio instruments, motors and electric appliances.The quality of the die directly affects the quality of the pressure processing technology, the precision of the product output and production cost, and the quality and service life of the die in addition to the reasonable structure design and processing accuracy, mainly affected by the die material and heat treatment.

Stainless steel rod

According to the production process, stainless steel bars can be divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used to manufacture mechanical parts or seamless steel pipe billets .

H-beam

H-section steel is an economic section efficient section with a more optimized cross-sectional area distribution and a more reasonable weight-to-weight ratio. It is named because its section is the same as the English letter "H". With each part of the H-beam arranged at a right angle, the H-beam has advantages of strong bending resistance, so it is widely used in simple construction, cost saving, light weight structure and son on.

lead

Lead sheet is a radiation protection material. It is made of raw material with high level of lead content (99.99%).It has stable protective performance and is a necessary protective material of x-ray machine. We supply lead sheet with different specifications and custom-made sizes.
