China China Thrie Beam Guardrail Manufacturers and Factory

The guardrail is mainly to follow the AASHTO M180, GB-T 31439.1-2015 and EN1317 standard. The material for that are mainly the Q235B (S235Jr the yield strength is more than 235Mpa) and Q345B (S355Jr the yield strength is more than the 345Mpa). For the thickness of the guardrail mainly through the 2.67mm to 4.0mm. China St37-2 / S235jr / 1.0037 Hot Rolled Structural Steel S235JR / ST37-2 / 1.0037 is a structural grade steel with a minimum yield strength of 275 N/mm² which widely used in the engineering and construction industries. S235 offers high yield and tensile strength and is supplied with a variety of treatments and test options to ensure it is a highly usable steel in your various projects. Applications:

EN 10025-2 S355JR high strength structural steel plate

S355 a structural grade steel with a minimum yield strength of 355 N/mm² which widely used in the engineering and construction industries. S355 offers high yield and tensile strength and is supplied with a variety of treatments and test options to ensure it is a highly usable steel in your various projects. Material selection and product specification In the CEN product standards, the primary designation relates to the yield strength, e.g. S355 steel is a structural steel with a minimum yield strength (R eH) of 355 N/mm 2. The number quoted in the designation is the value of yield strength for material up to 16 mm thick. Q235 Steel Equivalent, Properties, Specification, CompositionQ235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm).

S235JR Steel Pipe - Tianchuang Steel Pipe Manufacturer

Grade S235JR is structural grade (S) with a minimum yield strength of 235 N/mm²m, but in which a "rolling condition" is provided. S235 has good high yield and tensile strength, but if the material is heat treaed at the temperature over 600, it will be affected. Usage of S235JR Steel Pipe S235JR steel plateS235JR steel plate. S235JR Material Introduction EN 10025 S235JR material (1.0038 steel) is an European standard hot rolled non-alloy structural steel grade. It has good plasticity, toughness and weldability, certain strength and good cold bending properties.We have large quantities of S235JR in stock with thicknesses up to 200 mm. St37-2 - BEBON steelST37-2 steel is Non-alloy steel. ST37-2 steels Mechanical properties is Yield strength more than 235MPa, tensile strength 360-510Mpa.ST37-2 steel is mainly used for riveting, bolting, welding purposes. Structural Steels like ST37-2 is used in many applications, combining good welding properties with guaranteed strengths.

Sections Beams S355J2+AR/+M/+N (1.0577) HEA - HEB -S235JR Non-alloy quality structural steel - Material GradesThe tensile strength of the S235JR non-alloy steel is eed in Newton per millimeters and it should be in the range of 360 to 510 N/mm2 (MPa). The elongation property of S235JR steel changes with the heat treatment process and varies with the thickness. It is referred normally between 10% 25%.
