You Can Speed Up
Production by
Using Our
Cutting
Facilities
Approximately six out of every ten
orders received now call for some
pre-production cutting. More and
more customers are realizing that
this is one way to contend with high
production costs.

CSA G40.21
Standard for Structural Steels
Issued by Canadian Standards Association (CSA)
This standard, known as CSA G40.21 covers six types of structural quality
plates, shapes and bars for general construction and engineering purposes.
The six different types covered are:
Type G – General Construction Steel
Type W – Weldable Steels
Type T – Weldable Low Temperature Steels
Type R – Atmospheric Corrosion Resistant Structural Steels
Type A – Atmospheric Corrosion Resistant Structural Steel
Type Q – Quenched and Tempered Low Alloy Steel Plate
AVAILABILITY
These seven strength levels and six types have been combined into eighteen grades
as follows:

TYPE G – A general construction steel meeting minimum strength requirements, but not recommended for low temperature service. Primarily
designed for applications requiring bolting. However, can be welded under
carefully controlled shop conditions, but not recommended for field welding
where control may be difficult to maintain.
TYPE W – Weldable steels for general construction. Available in six strength
grades. These steels are widely used for bridges and other dynamically
loaded structures. Grade 44W is recommended for normal building construction where field or shop welding procedures are used. Not specifically
recommended for low temperature applications.
3MPage 3
TYPE T – Weldable, low temperature steel. A superior quality, weldable
structural steel, with chemical composition that makes it suitable for low temperature applications. Possesses good notch toughness in the “as rolled”
condition. Used for bridge construction for all types of loading. Certified minimum impact test requirement available. Easily weldable, using good shop
or field practices, by all the usual methods.
TYPE R – Steels with an atmospheric corrosion resistance of approximately four times that of carbon steel without copper. This type of steel usually
limited to 1⁄2" in thickness and up to this thickness may be readily welded
using good shop and field practices. Most popular applications unpainted
roofing, siding, facia and curtainwall.
TYPE A – Top quality steels for plates and shapes. High strength, low alloy
steels with good low temperature properties and providing good long term
atmospheric corrosion resistance. Weldable in all thicknesses. Widely used
in painted or unpainted condition for bridge construction, for exposed beams
and columns and for other types of construction.
TYPE Q – QUENCHED AND TEMPERED LOW ALLOY STEEL PLATE.
Steels that display a very high yield strength and good resistance to brittle
fracture. Suitable for bridges and other structures. May be welded providing
the techniques used do not adversely affect the properties of the plate.
