Class Code 5633 covers high‑wage workers engaged in steel framing operations in California. This classification applies to employees who fabricate, handle, and install steel framing members for commercial and industrial buildings. The September 1, 2026 approved pure premium rate for this code is $5.321 per $100 of payroll.
This class applies to operations that fabricate, assemble, transport and install steel framing members — including metal studs, joists, tracks, channels, light‑gauge and heavier gauge shop‑fabricated framing — used in walls, floors, roofs and mezzanines. Work covered includes both shop prefabrication of framed assemblies and field erection of framed systems for commercial, institutional and multi‑family construction when employees are paid at higher wage levels. Tasks can involve layout from plans, cutting and fitting steel members, fastening with screws or welds, rigging and setting prefabricated panels, and finishing connections. Supervisors, lead hands and experienced journeymen with above‑average wages who perform or directly oversee these operations are typically assigned to the high‑wage version of the steel framing class.
The pure premium rate of $5.321 per $100 of payroll represents the expected cost of indemnity and medical claims for this classification before insurer expenses and profit. Insurers multiply that pure premium by an employer’s actual payroll in hundreds of dollars, then apply policy level factors: loss cost multipliers, insurer expense loads, and the employer’s experience modification. Final premium is affected by payroll allocation, claim history, safety programs, return‑to‑work practices, and any class code audits or misclassification adjustments.
Cal/OSHA standards most relevant to steel framing include fall protection rules for construction work, scaffold and ladder safety requirements, and controls for welding, cutting and brazing operations. Employers must implement fall protection plans, use properly erected scaffolds and certified aerial lift procedures, provide welding PPE and ventilation, and maintain hazard communication for coatings and metalworking fluids. Training, written procedures and equipment inspection records are required under California Title 8 construction safety regulations.
A PEO like Key HR helps employers in this classification by centralizing workers’ comp claims handling, delivering OSHA‑aligned safety programs and targeted training (fall protection, rigging, welding safety), and deploying return‑to‑work plans to limit indemnity costs. Key HR also ensures accurate payroll reporting and classification, assists with experience modification management, and provides access to loss control consultants to reduce frequency and severity of claims — all of which can lower the effective premium paid by the employer.
Get a QuoteAssign 5633 when employees perform shop fabrication or field installation of steel framing members and are paid at higher wage levels; crews focused on heavy structural steel erection or non‑framing metalwork may fall under different codes. Review job duties, percent of time spent on framing tasks, and payroll for supervisors to confirm correct classification—Key HR can assist with an audit and job‑task review.
Prioritize fall protection systems and training, enforce proper rigging and load‑securement procedures, require cut‑resistant gloves and eye protection, implement welding ventilation and PPE policies, and establish a formal return‑to‑work program. Consistent toolbox talks, equipment inspections, and prompt medical management of injuries reduce claim severity and the employer’s experience modification.
Not automatically; the high‑wage designation applies when job duties match steel framing operations and payroll reflects higher wage rates for those employees or supervisory staff. Insurers look at both the nature of the work and payroll allocation. A PEO or insurance advisor can help document duties and determine the correct class placement to avoid overpayment.
