Wev e been known as an outstanding quality producer all the years weve beenin operation. Quality control has always been a priority, one in which
management and workers both take pride.
At its state-of-the-art mills in Longview, Washington
and Calgary, Alberta, Prudential Steel produces steel
pipe, tubes and hollow structural sections which have
earned the company a first-class reputation for
product quality and customer service.
And whether its for agricultural or architectural
purposes, H.S.S. has a high strength-to-weight ratio
which makes it the product of choice for a variety
of projects.
The integrity of Prudential Steels production of
H.S.S. assures you of a product with exceptional
dimensional accuracy in areas such as straightness,
corner radius, and wall thickness.
For ease of detailing, fabrication and erection,
H.S.S. produced by Prudential Steel is a product you
can rely on.
In fact, Prudential Steels H.S.S. makes it the
product of choice for projects in many industries:construction, telecommunications, transportation,
materials handling, agriculture, mining, and
petroleum. Whatever your project, Prudential Steel
has, in stock, the range of sizes, shapes and grades to
meet your needs for immediate delivery.

AThe minimum elongation values specified apply only to testing
performed prior to shipment because of the possibility of strain
aging. Tests performed after shipment may show values below
those stated.B Applies to specified wall thicknesses 0.120 in. and over. For
wall thicknesses under 0.120 in., the minimum elongation shall
be calculated by the formula: percent elongation in 2in. = 56t +
17.5.C Applies to specified wall thicknesses 0.180 in. and over. For
wall thicknesses under 0.180 in., the minimum elongation shall
be calculated by the formula: percentage elongation in 2in. =
61t +12.D Applies to specified wall thicknesses 0.120 in. and over. For
lighter wall thicknesses, elongation shall be by agreement with
the manufacturer.NOTE:The following table gives calculated minimum values for

Tolerances include allowance for convexity or concavity. For rec-
tangular tubing having a ratio of outside large to small flat dimen-
sion less than 1.5, and for square tubing, the tolerance on small flat
dimension shall be identical to the large flat dimension tolerance.
For rectangular tubing having a ratio of outside large to small flat
dimension in the range of 1.5 to 3.0 inclusive, the tolerance on
small flat dimension shall be 1.5 times the large flat dimension
tolance. For rectangular tubing having a ratio of outside large to
small flat dimension greater than 3.0, the tolerance on small flat
dimension shall be 2.0 times the large flat dimension tolerance.
