Hot Rolled H Sections
1. Brief
On completion of construction, the Hot H Section Plant of Masteel
was put into operation in September of 1998,Built with the technology
and equipment imported form DEMAG, SIEMENS (Germany) and ITAM
(USA), up to 90‘―s world advanced technical level, the plant is
the first production line of H sections in China. The plant can
now organize production in accordance with China national standards,
producing H sections with webs of 200-800 mm high and sheet piles,
but also can provide the products to the Japanese, British and
American standards.
From the time the plant began its production, its products have
been widely used in various fields such as civil building, mechanical
manufacture, petroleum power generation, communication, etc. and
also used in may large or small projects like China Century Monument
in Beijing, Xiamen Exhibition Center (Xiamen City), Aomen City
Sovereignty Hand-over Ceremony Hall, Guangzhou Yajisha Bridge,
for manufacturing new vehicles used in Railway Engineering Ministry,
petroleum prospecting platform at Bohai Sea, Dayawang Nuclear
Energy Power Generation Station, etc. Moreover its products have
successfully found the markets in America and Canada. The products
of the plants have been accredited by ISO9002-2000 first, later
by German Lloyd‘―s Register of Shipping and won the title of newly-developed
product in China.
Characteristics of H Sections
Wide flange, high rigidity, and high bending resistance.
With wide flanges and parallel surfaced, it is easy for mechanical
processing and installation, make connection of steel structure
much easier.
Actually, substitution of H section rolling for welding process
can save production cost by about 30%.
With a same sectional load bearing capacity, the weight of the
steel structure made with H sections can be reduced by 15-30%.
Depending on its different application in bearing loads, the H
sections can be approximately classified in three series products
namely H beams H columns and H piles.
