COLD ROLLED SHEETS

Commercial Quality - These sheets are rolled to a close thickness tolerance and possess a fine surface
finish. Cold Rolled Sheets are suitable for stamping, forming and moderate drawing
operations. Very desirable nickel or chrome plating results can be secured. Also, Cold
Rolled Sheets provide an excellent base for baked enamel and lacquer finishes.

GALVANIZED SHEETS

Commercial Quality (Lock Form Quality) - A continuous mill annealing and
galvanizing process produces sheets with a tight, even coat of spangle that will not flake
or peel in forming operations. Normally stocked in a G-90 coating weight.

GALVANNEALED SHEETS

Commercial Quality - Galvannealed sheet is carbon steel coated with
zinc on both sides by the continuous hot dip process. Immediately as the strip exits
the coating bath, the zinc coating is subjected to an in-line heat treatment that
converts the entire coating to a zinc iron alloy, giving the sheet a better surface
for painting. Normally stocked in an A-60 coating weight.

ALUMINIZED SHEETS

Commercial Quality - Aluminized coated carbon steel sheets have an
aluminum and silicon alloy coating on both sides. They are principally used in
heat-resisting applications and also where corrosion and heat are involved.

ASTM A1011 CS TYPE B HOT ROLLED SHEETS HOT ROLLED PICKLED AND OILED SHEETS

A prime quality low carbon sheet suitable for forming, punching, welding, etc. Sheets will
be furnished in standard mill edge unless sheared edge is specified. Hot rolled sheets are
commercial quality and in most sizes temper flat to improve flatness and relieve internal
stress.

HIGH-STRENGTH-LOW-ALLOY (HSLA) Sheets

SPECIFICATION: HR A1011 HSLA-F
Temper Flat
*GR
*16 ga is GR 50
High Strength Sheet Steels have higher strength properties along with improved formability,
weldability and/or atmospheric corrosion resistance than normally obtained from
conventional carbon sheet steels. These desirable properties are obtained through
selected chemical composition and controlled mill processing. High strength steels
lend themselves to applications where weight reduction is a major factor.

SCS (Stretched Clean Surface) HR Sheet

SCS is a patented process where the material is stretcher leveled, producing a dead flat
product. After the material is stretched flat, it is brushed to remove the upper 2 layers
of scale leaving a smooth, clean surface. The final layer of scale, which is left on the
sheet, will inhibit rust without the need for oil. It can even be painted without the costly
clean up required for pickled and oiled.

ASTM A-36 HOT ROLLED PLATE

A-36 is a structural quality carbon steel used for use in a variety of general construction
applications including; bolted, riveted, or welded construction of bridges and buildings.
Minimum yield point is engineered at 36,000 psi. In addition to greater strength than A-283,
A-36 plates can be used to design structures and equipment lighter in weight with better
weldability.

1020 HOT ROLLED PLATE

The controlled carbon range of 1020 improves the machinability of this grade. Good formability
and weldability are also characteristic.

FLOOR PLATE

Floor Plate is an economical safety flooring that gives long life under the most severe usage.
Its raised lug pattern is scientifically designed to resist skidding and slipping in any
direction and makes possible safer and faster movement of men and materials.

High Strength ASTM A-588 Gr. A/B

ASTM A-588 Gr. A/B steel plate offers all the advantages of ASTM A572-50 but is produced with
elevated levels of copper to add corrosion resistance. This "weathering" grade is often used in
unpainted applications such as bridges, utility sign/poles and highway structures and guardrails
because of the self-repairing, natural oxide patina greatly reduces maintenance.

HIGH STRENGTH ASTM A-572 Gr. 50

This high strength, low alloy steel plate offers an optimum combination of strength, weldability
and notch toughness with economy. Applications include: bridges, buildings, automotive and truck
parts, railroad cars, cargo containers, tote boxes, construction equipment, structural tubing,
lighting standards and transmission poles.

1045 HOT ROLLED PLATE

1045 is silicon killed with a higher carbon content for greater strength. Strength can be
improved in the lighter and medium thicknesses by heat treatment. Machinability is good,
while forming and welding properties are limited.

ASTM A-516 Gr. 70 (PVQ) ASME SA516-70

Intended primarily for service in welded pressure vessels where improved notch toughness is
required, this grade of ASTM A516/ASME SA516-70 is normally found in moderate and lower
temperature applications.

ABRASION RESISTING PLATE

that would give prolonged service life where abrasion is the primary cause of failure. The
surface hardness of Abrasion Resisting Steel will vary by grade from 200-500 Brinell.

ARMOR PLATE MIL-A-46100 (e)

A popular high hardness armor grade (HHA), 46100 is selected for use by all departments
and agencies of the Department of Defense. This grade is produced to 2 inches (51mm)
thick with hardness requirements of 477-534 BHN and Charpy Impact testing on every plate.

High Strength ASTM A-656 Gr. 80

ASTM A-656 Gr. 80 combines outstanding toughness, ease of fabrication and positive
strength to cost relationships when compared to A572-50 and A-36. These translate
into real savings in applications such as telescopic cranes, truck trailers, railroad
cars, construction equipment and transmission towers; or any other extreme load-bearing
job where the economy of superior strength and weight are paramount.

ASTM A-514 PLATE (Grade B, Grade H, Grade F, Grade Q)

The A514 plate steels are a group of quenched and tempered alloys with attractive
advantages and characteristics. The most important are high yield strength at 90 or
100 ksi minimum, weldability, and good toughness at low atmospheric temperatures.
Designed for a wide range of structural uses as well as machinery and equipment,
these alloy steels offer help with selecting the optimum in strength, toughness,
corrosion resistance, impact-abrasion resistance, and long-term economy.

Clean-Cut 20®/LFM 20/FM 15®/1119 Modified

The Clean-Cut/LFM 20 families of plate steel were developed for improved machining.
Produced by a special calcium treatment and a controlled sulphur process, Clean-Cut
steels contain sulfide inclusions which are predominately calcium modified to make
them smaller and more uniformly distributed. The result: enhanced machinability.
The economy of Clean-Cut steels can be realized in reduced wear and breakage
of machine tools, a reduction in machining time and increased productivity. Also,
the improved internal quality of Clean-Cut produces a superior machined surface
compared to free machining carbon steels.

1144 MODIFIED

1144 Modified offers high strength and hardness and is applicable where resistance
to deformation and wear are essential. It may be flame hardened to further enhance
surface properties. It is frequently used as an economical replacement for more
expensive quenched-and-tempered alloy grades.

100XF TEMPER LEVELED PLATE

100XF steel plate has been developed for applications where increased strength-to-
weight ratios are required. It has physical properties similar to those of ASTM A514
even though its manufacturing process does not require heat treatment.

MANGANESE PLATE (11% - 14% Manganese)

Manganese plate is a nonmagnetic steel that work hardens to a 650 Brinell. It is a
12-Mn austenitic steel with an exceptionally high level of wear-resistance when subject
to work-hardening by shocks or high pressures in service.
