Type of H beam
There are many product specifications of H-beams, and the classification methods are as follows.
(1) According to the flange width of the product, it is divided into wide flange, medium flange and narrow flange H-beams. The flange width B of wide flange and medium flange H-beam is greater than or equal to the web height H. The flange width B of narrow flange H-beam is approximately equal to one-half of the web height H. The flange width of narrow flange H-beam is approximately equal to the web height H.
(2) According to the product use, it is divided into H-beam, H-beam column, H-beam pile, and very thick flange H-beam. Sometimes parallel-legged channels and parallel-flange T-beams are also included in the range of H-beams. Generally, narrow flange H-beam is used as beam material, and wide flange H-beam is used as column material, according to which there are beam H-beam and column H-beam.
(3) According to the production method, it is divided into welded H-beam and rolled H-beam. 
(4) According to the size specification, it is divided into large, medium and small size H-beams. Usually, the 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 and flange width of 530mm.

Usage of H beam

H-shape beam is widely used, mainly for: various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and industrial plants under high-temperature working conditions; large bridges requiring large load-bearing capacity, good cross-sectional stability and large span; heavy equipment; highways; naval skeletons; mine support; foundation treatment and dam projects; various machine components.

ADVANTAGES OF WELDED H-BEAM

Determined by the shape, the cross-sectional modulus, moment of inertia and corresponding strength of H-beam are significantly better than the same single weight of ordinary I-beam. H-beam has wide flange, thin web, many specifications and flexible use, and can be used in various truss structures to save 15% to 20% of metal. Since the flanges are parallel inside and outside and the edge ends are at right angles, it is easy to assemble and combine into various members, thus saving welding and riveting workload by about 25%, which can greatly speed up the construction speed and shorten the construction period.

APPLICATION OF H-SHAPE STEEL BEAM

H-shape steel beam is mainly used for beam and column members in industrial and civil structures. 
◆ Steel structure bearing support for industrial structures 
◆ Steel pile and support structure for underground engineering 
◆ Industrial equipment structure such as petrochemical and electric power 
◆ Large span steel bridge members 
◆ Ship and machinery manufacturing frame structure 
◆ Train, car and tractor beam support 
◆ Port conveyor belt and high speed baffle support 
H shape steel beam is an economic section steel, widely used in industry, construction, bridge, oil drilling platform, etc. According to forecast The demand for H-beam in China is about 2.5 million tons in 2005 and 5 million tons in 2010, but the current annual production capacity of H-beam in China is 1.2 million tons, and the market demand is very huge.

Packing

There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security. Our packing can meet any  needs of the customers.

Plastic caps plugged at the two sides of pipe ends
Should be avoided by the steel strapping and transport damage
Bundled signs should be uniform and consistent
The same bundle(batch) of steel pipe should be came from the same furnace.
The steel pipe has the same furnace number, the same steel grade, the same specifications.
