EN H-Shaped Steel Construction h Beam
H-beam steel is widely used, mainly used for: a variety of civil and industrial building structures; A variety of long-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and high temperature working conditions; Large Bridges with large bearing capacity, good cross-section stability and large span are required; Heavy equipment; Highway; Ship skeleton; Mine support; Foundation treatment and dam engineering; Various machine components.
PRODUCT PRODUCTION PROCESS
The flange of H beam is parallel or nearly parallel on the inside and outside, and the end of the flange is at a right Angle, so it is named parallel flange I-steel. The thickness of the web of H-shaped steel is smaller than that of ordinary I-beams with the same height of the web, and the width of the flange is larger than that of ordinary I-beams with the same height of the web, so it is also named wide-rim I-beams. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight. Used in different requirements of the metal structure, whether it is under bending torque, pressure load, eccentric load show its superior performance, can greatly improve the bearing capacity than ordinary I-steel, saving metal 10% ~ 40%. H-shaped steel has wide flange, thin web, many specifications, and flexible use, which can save 15% to 20% of metal in various truss structures. Because its flange is parallel inside and outside, and the edge end is at a right Angle, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting workload, and can greatly accelerate the construction speed of the project and shorten the construction period.

EN H-Shaped Steel
Grade: EN10034:1997 EN10163-3：2004
Specification:HEA HEB and HEM
Standard: EN
FEATURES
There are many product specifications of H-beam, and the classification methods are as follows.(1) According to the flange width of the product, it is divided into wide flange, middle flange and narrow flange H-beam.The flange width B of wide flange and middle flange H-beam is greater than or equal to the web height H. The flange width B of the narrow flange H-shaped steel is equal to about half of the height H of the web plate.(2) According to the use of the product, it is divided into H-type steel beam, H-type steel column, H-type steel pile and H-type steel beam with extremely thick flange.Sometimes the parallel leg channel steel and the parallel flange T-beam steel are also included in the range of H-beams.Generally, narrow flange H-beam steel is used as beam and wide flange H-beam steel is used as column. Accordingly, it is also known as beam H-beam steel and column H-beam steel. (3) According to the production method, it is divided into welded H-beam steel and rolled H-beam steel. (4) According to the size specifications are divided into large, medium and small H-shaped steel.Generally, products with web height H above 700mm are called large, 300 ~ 700mm are called medium, and those less than 300mm are called small.By the end of 1990, the world's largest H-beam web height of 1200mm, flanged width of 530mm.
PRODUCT INSPECTION
The requirements for H-shaped steel inspection mainly include the following aspects:
Appearance quality: The appearance quality of H-shaped steel should comply with relevant standards and ordering requirements. The surface should be smooth and flat, without obvious dents, scratches, rust and other defects.
Geometric dimensions: The length, width, height, web thickness, flange thickness and other dimensions of H-shaped steel should comply with relevant standards and ordering requirements.
Curvature: The curvature of H-shaped steel should comply with relevant standards and ordering requirements. It can be detected by measuring whether the planes at both ends of the H-shaped steel are parallel or using a bending meter.
Twist: The twist of H-shaped steel should comply with relevant standards and ordering requirements. It can be detected by measuring whether the side of the H-shaped steel is vertical or with a twist meter.
Weight deviation: The weight of H-shaped steel should comply with relevant standards and ordering requirements. Weight deviations can be detected by weighing.
Chemical composition: If H-shaped steel needs to be welded or otherwise processed, its chemical composition should comply with relevant standards and ordering requirements.
Mechanical properties: The mechanical properties of H-shaped steel should comply with relevant standards and ordering requirements, including tensile strength, yield point, elongation and other indicators.
Non-destructive testing: If H-shaped steel requires non-destructive testing, it should be tested in accordance with relevant standards and ordering requirements to ensure that its internal quality is good.
Packaging and marking: The packaging and marking of H-shaped steel should comply with relevant standards and ordering requirements to facilitate transportation and storage.
In short, the above requirements should be fully considered when inspecting H-shaped steel to ensure that its quality meets relevant standards and ordering requirements, and to provide users with the best H-shaped steel products.
Application
Common H-beam steel materials include Q235B, SM490, SS400, Q345 and Q345B.The chemical composition and mechanical properties of these materials are different, so when choosing the use of H-beam, it is necessary to choose the appropriate material according to the specific situation
PACKAGING AND SHIPPING
Packaging and protection:
Packaging plays a vital role in safeguarding the quality of ASTM A36 H beam steel during transportation and storage. The material should be securely bundled, using high-strength straps or bands to prevent movement and potential damage. Additionally, measures should be taken to protect the steel from exposure to moisture, dust, and other environmental factors. Wrapping the bundles in weather-resistant material, such as plastic or waterproof fabric, helps protect against corrosion and rust.
