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. Here’s our equipment line-up for steel structurals – IN-PLANT FACILITIES BAND SAWING FLAME CUTTING CIRCULAR COLD CUT SAWS SAW TOLERANCE ± 1⁄16"

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.
