The square steel pipes refers to a long, hollowed cylinder
with rectangular or square cross section. It is made of strip
steel. Firstly a coil of steel strip is unwound, flattened, bent
and welded to form the desired profile. Then the section is cut to
the required length.
Sometimes also referred to as box section, our square hollow
section exhibits the same flexural strength and tensile strength as
the solid round tube while having lighter weight than the latter.
Durable and dependable, the box section does have a temptation, due
also to the cheap price. Plenty of applications exist for the box
section. The product can be used to make automobile, industrial
machinery, railway, highway guardrail, agricultural greenhouse,
container framework, furniture, and other steel structure.
Not only are the standard square hollow sections available, we also
can hand make bespoke products according to the typical industrial
applications.
