CSSBI 10M-2018:

Standard for Steel Roof Deck

may be reproduced in any form without the written permission of the publisher.

PREFACE

One of the objectives of the Canadian Sheet Steel Building

Institute is the development of product standards to promote

safety and sound construction practices. This Standard is

intended to assist speciers, designers, buyers, manufacturers

and erectors of steel roof deck by providing information which

can be adopted by reference where desired. This Standard

replaces the previous edition dated October 2013.

Steel roof deck is a basic component of the overall roof system

which normally would also include the roof framing, the various

roong materials, and other items necessary to provide a

complete assembly. A compatible relationship between the

various roof system components is an important consideration

when job plans and specications are being developed. It is

intended that this Standard for Steel Roof Deck will provide

useful guidance to designers and speciers, as well as to

suppliers and trades involved in roof construction.

The requirements contained herein are in accordance with

sound engineering principles, augmented by experience.

They include recommended minimum requirements for

grade of steel, base steel design thickness, metallic coating

designation, loads, resistances and deections, as well as

design, fabrication and erection in general. While the material

is believed to be technically correct and in accordance

with recognized practice at the time of publication, it does

not obviate the need to determine its suitability for a given

situation. Neither the Canadian Sheet Steel Building Institute

nor its Members warrant or assume any liability for the

suitability of the material for any general or particular purpose.

In the event of any conict between this Standard

and any legal regulations, such regulations

shall apply and this Standard shall only supplement

as applicable.

2.2 Where reference is made to another publication,

such reference shall be considered to refer to the

6.2 Vapour Retarder

A vapour retarder is required for the majority of

applications.

6.3 Insulation

Steel roof deck shall be insulated with a suitable

insulating material of sucient thermal resistance to

prevent condensation under normal occupancy

conditions. Additional insulation, beyond this

minimum requirement, is usually desirable for

thermal eciency. Insulation shall be properly

installed.

All sheet metal work, such as ashings, shall be

detailed and furnished by others unless otherwise

specied.

6.5 Field Painting

Any eld painting is the responsibility of the Buyer

who should check with the paint supplier for the

proper paint type and application procedures. Primer

that may be required to cover wet staining

discolouration is not the responsibility of the deck

supplier.

7. SAFETY DURING ERECTION

7.1 Minimum safety requirements for steel roof deck

erection are outlined in 7.2 to 7.8 inclusive. In the

event of any conict between these requirements

and any legal regulations, such regulations shall

apply and these requirements shall only supplement

as applicable.

7.2 All steel roof deck being hoisted to the working level

shall be adequately banded and carefully slung

employing steel wire rope and a choker type sling or

multi lift beams.

7.3 All bundles shall be tag lined during the ascent of the

hoisting operation. Bundles shall be placed so as to

avoid overloading the supporting structure.

7.4 All steel roof deck sheets, after being laid and

aligned, shall be properly secured in place prior to

leaving the jobsite at the end of each working day.

7.5 All loose bundles of steel roof deck sheets shall be

secured at the completion of each working day.

7.6 All steel roof deck cuttings, strapping, packaging

material, and other debris pertaining to steel roof

deck shall be removed from the roof area each

working day and disposed of in a suitable manner.

7.7 Perimeter safety lines, safety lines at discontinued or

incomplete construction and barricading of openings

shall be the responsibility of the General Contractor.

7.8 Steel roof deck is designed primarily to support

uniformly distributed load. Care shall be taken

to avoid excessive concentration of loads during the

temporary storage of materials for sub-trades.
