Specify shaftwall CH studs by matching the complete shaftwall assembly to the project drawings, specifications, required dimensions, and manufacturer documentation. Do not select a profile based only on a familiar name or assume that a standard dimension will suit every project.
The correct process begins with the wall assembly and ends with technical confirmation. That means reviewing design documents, identifying the required CH stud details, checking compatibility with surrounding components, and giving the supplier enough information to quote the right product.
1. Identify the shaftwall assembly before choosing a CH stud
A CH stud is one part of a shaftwall framing system, so it should not be selected in isolation. Start by identifying where the wall is located, which wall type applies, and what the assembly is intended to achieve within the project.
Collect the relevant floor plans, wall-type schedules, sections, enlarged details, specifications, and addenda. Look for the detail or assembly reference that governs the shaftwall rather than relying on a general metal framing note elsewhere in the drawing set.
Once you have identified the applicable assembly, compare its terminology with the supplier’s product terminology. Dass Metal Products lists shaftwall and CH studs among its steel framing products, but the project documents must still control selection of the specific profile and configuration.
2. Review the drawings and specifications for controlling requirements
Read the drawings and specifications together. Drawings may identify the wall type, location, dimensions, openings, and interfaces, while specifications may define materials, finishes, submittals, installation requirements, or referenced standards.
Record every reference that appears to control the shaftwall framing system. Useful information may include the wall-type designation, section detail, stud description, required length, connection detail, liner or board arrangement, and notes about penetrations or transitions.
Do not resolve a conflict by choosing the most convenient interpretation. If a plan, section, schedule, and specification describe different products or dimensions, pause the selection and send the discrepancy to the responsible design professional.
3. Confirm the CH stud details instead of assuming standard dimensions
Build a product-information checklist from the approved documents. The request should identify the required profile designation and, where specified, its dimensions, gauge, material requirements, finish, and length.
Also confirm whether the project calls for a standard product or a profile with project-specific characteristics. Custom steel profiles may be relevant when documented geometry or an interface does not correspond to a supplier’s standard offering, but customization should be confirmed rather than assumed.
Exact dimensions, gauges, capacities, and other technical values must come from project documents and current manufacturer data. This article cannot establish those values for a particular shaftwall, and a product name alone is not enough to demonstrate suitability.
4. Check compatibility with the complete shaftwall framing system
Review how the CH studs interact with the rest of the assembly. Check the specified tracks, connectors, clips, liner or board system, perimeter conditions, openings, corners, intersections, and transitions shown in approved details.
Pay particular attention to locations where the shaftwall meets another framing system. The connection may affect the required profile, dimensions, installation sequence, or supporting components. A CH stud that appears correct on a schedule may still require confirmation at an unusual opening or interface.
Keep product selection tied to the documented assembly. Do not substitute a different stud, track, connector, or board arrangement because it appears similar. Any substitution should follow the project’s approved review process and the relevant manufacturer or design professional’s confirmation.
5. Verify the technical documents that support the selection
Before requesting a final quotation or submitting the product for approval, assemble the documents that support your review. Dass Metal Products provides technical resources such as product brochures, metric and imperial load tables, standards, and MSDS documentation.
Use each document for its intended purpose. A brochure can help identify product information, a load table can support a review where its conditions apply, and a standard or project specification can define an external requirement. None should be treated as an automatic project compliance decision without checking the exact application.
Confirm that documents are current and that the referenced product, dimensions, units, and conditions match the project. If the specification requires a particular submittal, certification, test report, or design professional review, include that requirement in the supplier inquiry.
6. Check quantities, lengths, packaging, and delivery requirements
Prepare quantity information from the project takeoff and identify required lengths for each profile. Separate different dimensions, gauges, lengths, and wall-type references rather than combining them into one general line item.
Document project-specific quantity assumptions, including how the project team has handled waste, cuts, damaged material, replacements, and changes. The supplier can price the request more clearly when required product quantities are separated from allowances or unresolved quantities.
Include the delivery location, site access limitations, receiving requirements, requested delivery window, and any cross-border considerations. Dass Metal Products states that it serves customers across Ontario, Canada, and the United States, but availability, timing, and delivery arrangements still need confirmation for the individual order.
7. Prepare a technically complete quotation request
A useful quotation request gives the supplier enough information to identify the product, evaluate the request, and highlight unanswered questions. Include the following where applicable:
- Project name, location, and the person responsible for technical decisions.
- Drawing numbers, revision dates, specification sections, wall-type references, and relevant detail numbers.
- Shaftwall location, assembly description, required profile, dimensions, gauge, material, finish, and lengths.
- Quantities separated by profile, dimension, gauge, length, floor, area, or wall type.
- Required tracks, clips, connectors, accessories, or related components identified in assembly details.
- Documentation requirements, including brochures, load tables, standards, MSDS documents, or project submittals.
- Delivery address, site restrictions, receiving instructions, requested timing, and cross-border information where relevant.
- Questions about custom profiles, substitutions, missing information, or technical review.
Attach relevant drawings and specifications instead of copying only a short product description. A complete reference set helps the supplier and project team identify whether the request is clear, incomplete, or inconsistent before an order is placed.
Stop points: when to seek engineering or manufacturer confirmation
Stop the selection process and request review when the assembly reference is missing, drawings and specifications conflict, or required dimensions and gauges are unclear. These details should not be filled in from memory or inferred from a generic product listing.
Technical confirmation is also appropriate for unusual geometry, complex openings, custom profiles, nonstandard interfaces, or applications where structural, fire, acoustic, deflection, or other performance requirements control the design. The responsible engineer, architect, authority, or manufacturer should confirm the applicable requirements.
Do not use general article guidance as a replacement for project engineering, code review, or authority approval. If a requested product would be a substitution, document the proposed change and follow the project’s formal approval procedure before procurement.
What to look for in a shaftwall CH stud supplier
Evaluate suppliers on more than a product name or quoted price. Look for product-specific documentation, clear technical communication, and the ability to distinguish standard products from requests that need further review.
Engineering support is particularly useful when a project involves custom profiles, conflicting information, or a detailed submittal process. Dass Metal Products states that its engineering team has more than 40 years of steel framing experience and supports customized profiles.
Also consider manufacturing location, quality information, documentation availability, and delivery coverage. Dass Metal Products is a Canadian manufacturer and supplier based in Vaughan, Ontario, and states that it supports projects across Canada and the United States. These factors can help organize procurement, but they do not replace confirmation of suitability for a specific assembly.
FAQ about shaftwall CH studs
What are shaftwall CH studs used for?
Shaftwall CH studs are steel framing components used as part of a shaftwall assembly. Their selection depends on the complete wall system, including surrounding framing, liner or board arrangement, connections, openings, and project requirements.
What should I confirm before ordering shaftwall CH studs?
Confirm the assembly reference, profile designation, dimensions, gauge, material requirements, finish, lengths, quantities, related components, documentation, and delivery details. Also verify that drawings and specifications agree.
Can I assume shaftwall CH studs have standard dimensions and gauges?
No. A supplier may offer standard products, but project documents and current manufacturer information must establish which dimensions and gauges apply. Do not infer the selection from wall thickness, a previous project, or a similar-looking product.
When should an engineer or manufacturer review the CH stud selection?
Request review when the assembly is performance-critical, documents conflict, geometry is unusual, a custom profile is required, or the selection involves a substitution. Review is also appropriate when required dimensions, gauge, compatibility, or documentation cannot be established from approved project information.
Conclusion: confirm the assembly before you order
Correctly specifying shaftwall CH studs is a document and coordination task, not a guess based on a product label. Identify the assembly first, extract controlling requirements, check the complete framing system, verify supporting documents, separate quantities and lengths, and prepare a quotation request that exposes unanswered questions.
When the project includes conflicting documents, custom conditions, or performance requirements, obtain technical confirmation before procurement. For product information, technical review, or a quotation request, contact Dass Metal Products about shaftwall CH studs.
