Proud Member Of Stairbuilders And Manufacturers Association
A stair business may design components, run a shop, deliver finished assemblies, or install them on site. Your insurance review should follow the work you actually take on.

From the shop floor to the installed stair
The Stairbuilders and Manufacturers Association connects the stairbuilding and stair-parts manufacturing community through education, technical resources, and collaboration. Its members’ roles and materials can differ considerably.
The Southern Agency retains SMA in its existing membership directory. The guidance here distinguishes fabrication from delivery and installation; it does not suggest that every member performs all of those activities.
Insurance considerations
The work that leaves your shop
Describe the components you make and where they are used. Discuss product liability and completed operations, including injury allegations after installation; the cost of correcting your own defective product is a separate question.
Machinery and production
Shop equipment, dust collection, and stored materials affect the review. Ask about property damage, equipment breakdown, and interruption of production, alongside maintenance, and fire prevention.
Installation and design duties
Explain who measures, prepares drawings, approves specifications, and installs the stair. Design allegations may need a professional liability discussion, while lifting and work at height affect employee injury exposures.
Industries
Use the finish-carpentry guide for installation work. The wood-component guide applies only to businesses making wood components; describe metal or other fabrication separately.
- Carpentry and Finish Trim ContractorFor stair and railing installers working at customer sites, including occupied buildings, installation responsibilities and tools carried to the job.
- Prefabricated Wood Component PlantFor businesses fabricating wood stair components in a shop; use the manufacturing context only where the materials and production work match your operation.
Policy types
Manufacturing and installation can create different policy questions within the same business. These are educational links, not evidence of a specialist SMA product or placement commitment.
- Product Liability InsuranceDiscuss injury or damage allegations involving manufactured stair components and the policy’s treatment of defects, recall costs, and your own product.
- General Liability InsuranceReview customer-site work, installation, and completed operations, identifying which tasks you perform and which are subcontracted to others.
- Commercial Property InsuranceList fabrication machinery, raw materials, and finished assemblies, and consider business income if a covered property loss stops shop production.
- Equipment Breakdown InsuranceAsk how a mechanical or electrical breakdown of production equipment is treated, separately from wear, maintenance, and ordinary property damage.
- Workers Compensation InsuranceSeparate shop duties from delivery and installation work, including lifting, cutting equipment, and work at height when describing payroll and tasks.
- Inland Marine InsuranceReview components in transit, stored assemblies, and installation tools, including when responsibility changes between your shop and the customer’s site.
Questions members ask
Should a stair manufacturer disclose installation work?
Yes. Explain whether you deliver only, install with your own employees or subcontract the work. Those activities can affect liability, vehicle, tools, and employee injury reviews.
Does product liability pay to remake a defective stair?
Do not assume it does. Injury or damage claims, repair of your own product, recall expenses, and contractual obligations are different issues. Ask your agent to explain the applicable exclusions and terms.
What if we also prepare designs or shop drawings?
Describe the design, engineering or specification responsibilities you accept, including approvals and contracts. Ask whether a separate professional liability review is needed; a link to a guide does not establish that a product is available for your services.
