Product information

Product names

  • ALMCAN Hurricane Tie
  • ALMCAN Joist Hangers
  • ALMCAN Rafter Tie

Product description

The joist hangers identified in the Results of testing of factored resistances of the hanger series table are used to transfer the loads from the supported member to the supporting member. They are face-mount hangers that are fabricated in cold-form with light steel gauge. The steel gauge of the hangers is indicated in the Results of testing of factored resistances of the hanger series table. A typical drawing of the hanger model series is shown in Figure 1.

The hurricane tie and rafter tie identified in the Results of testing of factored resistances of the hurricane tie and rafter tie table are used where additional protection is required against wind uplift from seismic and wind loads. They are fabricated in cold-form with light steel gauge. The steel gauge of the connectors is indicated in the Results of testing of factored resistances of the hurricane tie and rafter tie table. A typical drawing of the connector model is shown in Figure 2.

The steel of the hangers with model No. 452 to 462 is coated with a corrosion protection of G153 designation from the standard ASTM A 653/A 653M-04, “Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot Dip Process.” The steel of the other hangers and connectors is coated with a corrosion protection of G60.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The pre-engineered wood members assembled with the evaluated joist hangers must be designed in accordance with Part 4 of Division B of the NBC 2015 by a professional engineer licensed to practise under a provincial or territorial legislation.
  • The joist hangers are used to support joists consisting of lumber, wood trusses, glued-laminated timber, prefabricated wood I-joists or structural composite lumber. The pre-engineered wood members must conform to the manufacturer’s specifications and instructions (e.g., web stiffeners, filler blocks and backer blocks for I-joists).
  • The design values (factored resistances) for joist hangers provided in this Report are valid for the wood species and the hanger models shown in the Results of testing of factored resistances of the hanger series table. However, the design value (factored resistance) can be valid for other wood products provided that: 
    • the relative density (or compressive strength perpendicular to grain, fcp) of the proposed wood product is equal or superior to the actual wood product tested with the hanger; and 
    • where structural composite lumber (SCL) products are intended to be used, only TimberStrand® (LSL), Parallam® (PSL) and laminated veneer lumber (LVL) of vertical veneer are acceptable. Southgate Manufacturing Inc. must confirm acceptance of the use of a SCL product with their hanger and provide installation instructions.
  • Fastener specifications shown in the Results of testing of factored resistances of the hanger series and Results of testing of factored resistances of the hurricane tie and rafter tie tables must be used for the published values to be valid. The joist hanger must be fastened to both the supported member and supporting member. All fastener holes must be filled, or there must be a minimum number of nails as per the engineer’s specifications.
  • The hanger must not display any fracturing in either the protective coating or the base metal.
  • When used in attics, at rim boards or in high humidity or corrosive environments, the user must consult the manufacturer to determine the appropriate level of corrosion protection for the intended use of the joist hanger and connector.
  • The products must be installed by an informed and knowledgeable installer.
  • The products listed in the Results of testing of factored resistances of the hanger series and Results of testing of factored resistances of the hurricane tie and rafter tie tables must be identified with the phrase “CCMC 13287-R.”

CCMC recognition

The Canadian Construction Materials Centre (CCMC) assesses compliance with Canadian building, energy and safety codes. We are the only construction code compliance service supported and operated by the Government of Canada. Trusted by over 6,000 regulators across Canada.

Most Canadian authorities having jurisdiction (AHJs) consider CCMC product assessments acceptable as evidence for product approval.

CCMC assessments are recognized by construction authorities across Canada:

The CCMC provides code compliance assessments to Canadian code requirements, consulting nationwide with construction regulators to elicit regional variations in code requirements as well as provincial and local interpretations. Users are advised to review the technical information presented in CCMC assessments when making approval decisions. Learn more about how the CCMC provides a unique service for Canada.

Code compliance as an acceptable solution

Code Compliance via Acceptable Solutions

If a building design (e.g. material, component, assembly or system) can be shown to meet all provisions of the applicable acceptable solutions in Division B (e.g. it complies with the applicable provisions of a referenced standard), it is deemed to have satisfied the objectives and functional statements linked to those provisions and thus to have complied with that part of the Code.

National Building Code of Canada, Sentence A-1.2.1.1.(1)(a)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Acceptable Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

  • complying with the applicable acceptable solutions in Division B, or
  • using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.

Code compliance as an alternative solution

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions
